Description

SURGICAL TOOL AND RELATED METHODS RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application Serial Number 63/665,176 entitled “Surgical Tool and Related Methods”, filed June 27, 2024, which is incorporated herein by reference in its entirety. TECHNICAL FIELD [0002] The present disclosure generally relates to medical devices and more specifically to surgical tools. BACKGROUND [0003] Implantable neural interfaces (INIs) are devices configured to connect with the human nervous system through electrical means. Advantageously, such devices allow electrical recording and stimulation of the nervous system and may contribute to developing effective treatments for various nervous system diseases (e.g., chronic pain, arrythmia, Parkinson’s, Alzheimer’s, and poliomyelitis). [0004] However, the materials used for conventional INIs (e.g., silicon and noble metals) suffer from many limitations. For example, due to a relatively low impedance and small detection window, noble metals and silicon-based INIs have limited application during neural stimulation. Additionally, long-term implantable performance with such devices is poor due to the foreign body response, loss of target neurons, and scar formation (i.e., gliosis). In some instances, a base material, such as Si, has been known to make contact with the neural environment and trigger the body’s immune system response. In some instances this has led to undesirable device encapsulation with glial scar tissue resulting reducing device performance and patient discomfort. [0005] With rapid improvements in bionic limbs (prosthetic hands, arms, legs, etc.) new challenges arise in the efficient and transparent operation of these advanced devices. Electromyography (EMG) sensors may be used to detect and measure electrical signals in a patient’s muscle, however, this does not allow for specific neural interfacing. Performance using these sensors is limited due to the large number of neural signals that are picked up simultaneously at a single recording electrode, sometimes all at the same time. In addition, this type of interface does not lend itself to accurate and effective neural stimulation, for instance to individual nerves, thus bionic limb feedback signals cannot be fed back to the user. ^{HB: 4933-6586-4273.1} 1 [0006] A solution is desired that allows for an increase in the number of individual neural recording/stimulation points that are available, along with reliable, long-term electrode implantation in the peripheral nervous system (PNS). Such a device would preferably improve the number of bionic limb degrees of freedom possible, and also both reduce latency and improve accuracy as contemporary interfaces require a software algorithm and lengthy training to assess and estimate the patient’s intent. While technological advances have been made for interfacing with the central nervous system (CNS) (i.e., brain and spinal cord), neural recording and stimulation of the PNS is more challenging as nerves of the PNS often stretch, compress, twist, change cross-sectional area, etc. as a patient moves. Thus, unique solutions suitable for the PNS are required. [0007] Solutions are also desired that increase the stability and reliability of the connection between an electrode and the nerve or nerve bundle. The devices of the present disclosure provide for improved and secure placement of electrodes and connections to the nerve or nerve bundle, in some cases allowing for longer term deployment and reduced instances of failure and patient discomfort. SUMMARY [0008] Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings. [0009] Embodiments of the disclosure provide a device. The device comprises a body and a hook coupled to the body. The hook can be configured to receive a collar. The device comprises an arm coupled to the body. The collar can be positioned between the arm and the hook. The device comprises an actuator coupled to the hook. When the collar is in an open configuration, the collar can be positioned between and engaged by the hook and the arm. The collar can surround a peripheral nerve. From the open configuration, the actuator can be configured to pull the hook towards the body thereby forcing the collar to close around the peripheral nerve and force the collar into a closed configuration. [0010] In one embodiment, a body comprises a first section and a second section separated from the first section. The first section and the second section can define an actuator. The first section can be coupled to a hook. As the first section is pushed towards the second section, the hook can be pulled towards an arm to close a collar around a peripheral nerve. ^{HB: 4933-6586-4273.1} 2 [0011] In one embodiment, an actuator can be a first actuator. A device may also comprise a second actuator. The second actuator can be configured to insert a probe housing with a probe therein into a collar, when the collar is closed around a peripheral nerve.

[0013] In one embodiment, an arm comprises a first finger and a second finger. In an open configuration each of the first finger and the second finger can be configured to contact a collar. [0014] In one embodiment, after a collar is in the closed configuration, an actuator can be configured to force an arm further against the collar until the arm is released from the collar to remove the device from the collar. [0015] In one embodiment, an arm comprises a first finger and a second finger. The first finger and the second finger can be flexible.

[0026] In one embodiment, causing, when using the device, a collar to close around a peripheral nerve of a subject comprising engaging an arm of the device with a first portion of the collar and engaging a hook of the device with a second portion of the collar. The second portion of the collar can be pivotally coupled to the first portion of the collar. The collar can be positioned between the hook and the arm. In one embodiment of using the device, the collar closes around the peripheral nerve of the subject by pulling, using an actuator, the hook towards the arm to force the second portion of the collar to lock around the first portion of the collar. [0027] In one embodiment of using the device, inserting a probe housing into a slot of a collar comprises advancing, using an actuator, a plunger positioned within a channel of the device until the plunger contacts the probe housing positioned within the channel, and further advancing, using the actuator, the plunger until the probe housing is forced out of the channel and into the slot of the collar. [0028] In one embodiment, removing the device from a collar comprises advancing an arm of the device further towards the collar until one or more fingers of the arm deflect away from the collar to disengage the arm from the collar. ^{HB: 4933-6586-4273.1} 4 [0029] Embodiments of the disclosure provide a surgical device configured to implant a neural collar system.

DETAILED DESCRIPTION OF EMBODIMENTS [0097] For simplicity and illustrative purposes, the principles of the present invention are described by referring to various exemplary embodiments thereof. Although the embodiments of the invention are particularly disclosed herein, one of ordinary skill in the art will readily recognize that the same principles are equally applicable to, and can be implemented in other systems, and that any such variation would be within such modifications that do not part from the scope of the present invention. Before explaining the disclosed embodiments of the present invention in detail, it is to be understood that the invention is not limited in its application to the details of any particular arrangement shown, since the invention is capable of other embodiments. The terminology used herein is for the purpose of description and not of limitation. [0098] As used herein and in the claims, the singular forms include the plural reference and vice versa unless the context clearly indicates otherwise. Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients or reaction conditions used herein should be understood as modified in all instances by the term “about.” [0099] All patents and other publications identified are expressly incorporated herein by reference for the purpose of describing and disclosing, for example, the methodologies described in such publications that might be used in connection with the present invention. These publications are provided solely for their disclosure prior to the filing date of the present application. Nothing in this regard should be construed as an admission that the inventors are not entitled to antedate such disclosure by virtue of prior invention or for any other reason. All statements as to the date or representation as to the contents of these documents is based on the information available to the applicants and does not constitute any admission as to the correctness of the dates or contents of these documents. [00100] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as those commonly understood to one of ordinary skill in the art to which this invention pertains. Although any known methods, devices, and materials may be used in the ^{HB: 4933-6586-4273.1} 11 practice or testing of the invention, the methods, devices, and materials in this regard are described herein. [00101] In certain embodiments, the “collar” is essentially a strap that wraps around the nerve. The strap holds the electrode in place. [00102] In certain embodiments, the “hook” as used herein is a protruding portion of the end of the surgical tool that functions to grip and hold the probe mount collar. The hook doesn’t have to be a hook. It can be a peg, or just a knurled surface like the pattern you would see on the grasping surface of a pair of forceps. The hooks function as a pair of mandibles, in other words: opposable graspers. [00103] Referring now to FIG. 1, a schematic drawing is shown, illustrating a surgical device 100 configured to deploy a neural collar system and related electrode. The surgical instrument or device 100 may have device housing 102, with a proximal user end and a distal patient end, connected by a device shaft 104 in the mid-section. The proximal end may include a surface surrounding, partially or substantially entirely, several functional device parts configured to perform tasks within the surgical site of the patient. Such tasks may include deployment, extraction, adjustment, arrangement, etc. The proximal end may include several actuators that are moveable. The moveable actuators may be configured to cause motion of the functional device parts located at the distal end. The functional device parts may be connected to or coupled with the actuators by a plurality of actuator tendons (e.g., 160, 162, 164) that extend from the proximal end to the distal end of the device 100. The shaft 104 may be hollow or partially hollow and may house the actuator tendons. The shaft 104 may have a cross- sectional shape that is circular, oval, square or similar, including square with rounded corners or a shape that is generally one of the foregoing or combinations thereof, for instance circular on one side and generally square with rounded corners on the opposite side. The actuators, functional device parts, and actuator tendons will be described in further detail below. [00104] The proximal end of the device may also have a handle portion 108 formed within the device housing 102 or attached to or extending from the device housing 102 that can be used to position the device 100 and hold the device 100 in place while various functional device parts are actuated by the actuators. For example, the handle 108 may be include one or more rings 110 extending from the device shaft 104. The rings 110 may have an inner surface 112 that forms holes or grooves 114 configured to receive one or more fingers. The holes or grooves 114 may be circular, nearly circular, elliptical, “C”-shaped, “D”-shaped, or another shape. The rings 110 may also be incomplete, having gaps in a circumferential direction, such that the circumference of the grooves 114 is not fully surrounded. The handle 108 may also be formed ^{HB: 4933-6586-4273.1} 12 in the shape of one or more hooks that extend from the device shaft 104. Each hook may have a curved distal surface forming a space or grooves configured to receive one or more fingers. The handle 108 may also be formed from one or more arms extending linearly from the device shaft 104. The arms may have a distal surface forming a space or grooves configured to receive one or more fingers. The arms may be straight or curved, or include combinations of straight and/or curved sections. [00105] As indicated, the device housing 102 may also include a shaft 104 that connects the distal end to the proximal end. The shaft 104 may have a cavity that can contain or house a plurality of actuator tendons (e.g., 160, 162, 164), which will be described in further detail below. The shaft 104 may have a wall or surface that may define the cavity and surround or partially surround one or more, or all of the actuator tendons. The shaft 104 wall or surface may surround the length of the actuator tendons but leave one or both of the ends of the actuator tendons exposed. The actuator tendons (e.g., 160, 162, 164) may extend from the functional device parts at the distal end, through the shaft 104, to the actuators at the proximal end, coupling each of the actuators to a functional device part. [00106] The actuators may include a plunger actuator 120, a grip hook release 130, and a tongue actuator 150. The actuator tendons may include a plunger actuator tendon 160, a grip hook actuator tendon 162, and a tongue actuator tendon 164. Each of the actuators may function to slide one of the actuator tendons proximally or distally through the device shaft 104. For example, the plunger actuator 120 may slide the plunger actuator tendon 160 proximally or distally through the shaft 104. The grip hook release 130 may act to move the grip hook actuator tendon 162 through the shaft 104. Movement of the tongue actuator 150 may cause movement of the tongue actuator tendon 164. [00107] The plunger actuator 120 may include a plunger shaft 122 that extends proximally from the device housing 102. For example, the plunger shaft 122 may extend parallel to the device shaft 104. The plunger shaft 122 may fit into a plunger shaft cavity 128. The plunger shaft cavity 128 may be sized or configured to limit the motion of and/or to prevent accidental or unintentional distal motion of the plunger actuator 120. For example, the plunger shaft 122 may have a tight fit in the plunger shaft cavity 128. The plunger shaft cavity 128 or plunger shaft 122 may also have friction surfaces or grip teeth. The plunger shaft cavity 128 may also include a spring that biases the plunger actuator 120 for instance in the proximal position. [00108] The plunger actuator 120 may also include a plunger handle 124 coupled to the plunger shaft 122. The plunger handle 124 can provide a surface or grip that is pressable by a user to shift the plunger actuator tendon 160 distally. For example, the plunger handle 124 may ^{HB: 4933-6586-4273.1} 13 be a loop, one or more handlebars, a knob, one or more finger hooks, etc., that can provide a pressable surface. The handle 124 can be pushed distally by a user, moving the handle 124, plunger shaft 122, and a plunger actuator tendon 160 in the distal direction. The device may include a plunger block 126. For example, the plunger block 126 may include a proximal surface configured to abut the plunger shaft 122, preventing further distal motion of the plunger actuator 120. In this way, the plunger shaft 122 can slide distally through the device housing until the distal end of the plunger shaft 122 reaches the plunger block 126, stopping further motion. Similarly, the plunger block 126 may include a proximal surface configured to abut the plunger handle 124. The plunger block 126 may alternatively or additionally include tabs, protrusions, friction surfaces, teeth, bumpers, barbs, springs, etc. that prevent distal motion beyond a pre-determined desired distance. [00109] The grip hook release 130 may include a grip hook slide 132 and a spring 140. The grip hook release 130 may also include an optional handle 134, on which the grip hook slide 132 is disposed. The handle 134 may facilitate holding the surgical device while sliding the grip hook slide 132 against the force of the spring 140. The handle 134 may be a protrusion, finger loop, hook, handlebar, etc. that extends from the device housing 102 or handle 108. [00110] The grip hook slide 132 may be coupled to the grip hook actuator tendon 162, such that sliding the grip hook slide 132 causes the grip hook actuator tendon 162 to move proximally or distally through the device shaft 104. As FIG. 1 shows, the grip hook actuator tendon 162 may be curved away from the axis of the shaft 10 in a lateral direction to align with a grip hook actuator axis 14 that runs proximally/laterally and distally/medially. For example, the grip hook actuator axis 14 may be angled away from the shaft axis 10 by an angle θ 16. For example, the proximal end of the grip hook actuator tendon 162 may extend into the handle 134, which may be angled by an angle θ 16 with respect to the shaft 104. In this way, proximal/lateral motion of the proximal end of the grip hook actuator tendon 162 may translate to proximal motion of the distal end of the grip hook actuator tendon 162. Likewise, distal/medial motion of the proximal end of the grip hook actuator tendon 162 may cause distal motion of the distal end of the grip hook actuator tendon 162. Alternatively, the grip hook actuator axis 14 may be parallel to or aligned with the shaft axis 10 (i.e., θ = 0°) or aligned with the lateral-medial axis 12 (i.e., θ = 90°). [00111] The grip hook release 130 may have two switchable configurations. In a relaxed configuration (as shown in FIG.1), the spring 140 may be in a relaxed or equilibrium position while the grip hook slide 132 is positioned more distally/medially. In an engaged configuration, the spring 140 may be perturbed (i.e., stretched or compressed) into a state of tension while the ^{HB: 4933-6586-4273.1} 14 grip hook slide 132 is positioned more proximally/laterally, for instance towards an outer end of the handle 134. [00112] The grip hook slide 132 may be coupled to a proximal end of the grip hook actuator tendon 162. For example, the grip hook slide 132 may have an elongated shape that lines a part of a surface of the grip hook actuator tendon 162. The grip hook slide may also have a tab 136 or protrusion that facilitates pulling or sliding the grip hook slide 132 in the proximal/lateral direction, which causes the grip hook actuator tendon 162 to slide or move in the proximal direction. [00113] The grip hook slide 132 may also be coupled to a spring 140 that biases the grip hook slide 132 in the relaxed configuration. The spring 140 may be a helical compression spring, a torsion spring, a flexible or stretchable material, such as a rubber band, or another type of spring. The spring 140 may have a stationary end 142 and a moveable end 144. The stationary end 142 may be fixed to the device 100. For example, the stationary end 142 may have a ball that fits into a socket disposed in the handle 134 or the device housing 102. The stationary end 142 may alternatively be coupled to an inner or outer surface of the handle 134 or device housing 102. The moveable end 144 may be coupled to the grip hook slide 132. [00114] The spring 140 may be positioned such that sliding the grip hook slide 132 proximally/laterally stores potential energy in the spring 140, which may be used to return the grip hook slide back to its relaxed configuration, in which the grip hook slide is positioned distally/medially. For example, the stationary end 142 of the spring 140 may be distally/medially positioned relative to the moveable end 144 of the spring 140. Thus, when the grip hook slide 132 is slid proximally/laterally , the moveable end 144 is pulled away from the stationary end 142, stretching the spring 140 into an engaged configuration, in which potential energy is stored in the spring 140. When the grip hook slide 132 is released by the user, the spring 140 can relax back to its equilibrium state, causing the grip hook slide 132 to slide distally/medially toward the device 100, in which the grip hook actuator tendon 162 moves distally through the shaft 104. [00115] Analogously, the stationary end 142 may be positioned proximally/laterally relative to the moveable end 144 of the spring 140. In this case, pulling the grip hook slide 132 proximally/laterally can cause the spring 140 to compress, storing potential energy. Thus, releasing the grip hook slide 132 can cause the spring 140 to relax back to its equilibrium state, causing the grip hook slide 132 to slide distally/medially, in which the grip hook actuator tendon 162 moves distally through the shaft 104. ^{HB: 4933-6586-4273.1} 15 [00116] The grip hook release 130 may also include a grip hook block 138. For example, the grip hook block 138 may be a surface that abuts the proximal end of the grip hook actuator tendon 162 preventing further proximal/lateral motion. The grip hook block 138 may also have a surface that abuts the grip hook slide 132 or grip hook slide tab 136 to prevent further motion. The grip hook block 138 may also be accomplished by an increasing tension in the spring 140 as the grip hook slide 132 is moved proximally/laterally. The grip hook block 138 may also include tabs, bumpers, grips, teeth, friction surfaces, protrusions, or barbs that prevent proximal/lateral movement of the grip hook slide 132 past a predefined location. [00117] The tongue actuator 150 can be coupled to the tongue actuator tendon 164 such that translational or rotational motion of the tongue actuator 150 causes or actuates distal or proximal motion of the tongue actuator tendon 164 through the shaft 104. As a non-limiting example, the tongue actuator 150 may be located on the handle 108. For example the handle 108 may contain a cavity 116 through which the tongue actuator tendon 164 can extend. The tongue actuator 150 can be coupled to a proximal end of the tongue actuator tendon 164 on the handle 108. For example, the tongue actuator 150 may be a protrusion 152 that extends outwardly from the handle 108 in a radial direction 16 perpendicular to the outer surface of the handle. The protrusion 152 may form a handle and may include a hook 154 loop, one or more straight or curved sections, a finger groove, or combinations thereof configured to receive one or more fingers to facilitate movement of the tongue actuator 150. The protrusion 152 may also be a tab or grip that extends from the outer surface of the handle. [00118] In some examples, rotation of the tongue actuator 150 in a circumferential direction around the handle 108 may translate to proximal or distal motion of the tongue actuator tendon. In the example shown in FIG.1, clockwise rotation of the tongue actuator 150 may translate to distal motion of the tongue actuator tendon 164 while counter-clockwise rotation of the tongue actuator 150 may translate to proximal motion of the tongue actuator tendon 164. However, in other configurations, clockwise rotation of the tongue actuator 150 may cause proximal motion of the tongue actuator tendon 164 and vice versa, for instance depending on the attachment of the tongue actuator 150 and tongue actuator tendon 164. [00119] The tongue actuator 150 may further include a tongue actuator block 156. The tongue actuator block 156 can prevent motion of the tongue actuator 150 past a predefined position. For example, the tongue actuator block 156 may have a surface that abuts the tongue actuator 150 when the predefined position is reached, preventing further motion. For example, the tongue actuator block 156 may be formed in the cavity 116 of the handle 108. The tongue actuator tendon 164 may include a jut-out. For example, the jut-out may form an axial surface ^{HB: 4933-6586-4273.1} 16 158 on the tongue actuator tendon 164 that is perpendicular or nearly perpendicular to the long axis of the tongue actuator tendon 164. The axial surface 158 can abut the tongue actuator block 156. The tongue actuator block 156 may alternatively be formed from a tab that can be caught by a complimentary barb that protrudes from the tongue actuator tendon 164, for example. Additionally, or alternatively, the tongue actuator block 156 may extend outwardly from the outer surface of the handle 108 to abut a surface of the protrusion 152 of the tongue actuator 150. The tongue actuator block 156 may also include one or more springs, friction surfaces, barbs, teeth, bumpers, grips, or some combination thereof. [00120] Motion of the tongue actuator 150 may require the user to overcome a predetermined force to prevent accidental motion or deployment or to control the motion to a maximum speed. For example, the proximal end of the tongue actuator tendon 164 may tightly fit in the handle cavity 116, providing a frictional force to slow movement. The tongue actuator 150 may further include a spring that biases the tongue actuator tendon in a proximal position. For example, the spring may be positioned in the handle cavity 116 between the tongue actuator block 156 and a surface of the tongue actuator tendon 164. [00121] The shaft 104 may also include spacers 166 or void space 168 that separates the actuator tendons (e.g., 160, 162, 164). In this way, motion of each actuator tendon can be independent of the other actuator tendons. However, the actuator tendons may be in contact with one another. For example, the actuator tendons may have smooth surfaces with low friction, allowing them to glide past one another independently. [00122] As previously described, the actuators, including the plunger actuator 120, grip hook release 130, and tongue actuator 150, function to translate actuator tendons (e.g., the plunger actuator tendon 160, the grip hook actuator tendon 162, and the tongue actuator tendon 164, respectively) in a distal or proximal direction. Thus, the mechanisms described for each actuator may be interchangeable. For example, the mechanism of the grip hook release 130 may be used to achieve the plunger actuator 120, and so on. Likewise, the relative positions of the actuators and actuator tendons may be interchangeable as would be appreciated by a person of skill in the art. [00123] Referring now to FIG.2, the distal end of the surgical device 100 is shown if more detail. The functional device parts located at the distal end comprises an electrode hood 170, a plunger 172, a retractable grip hook 180, a stationary grip hook 182, a flexible tongue 190, and a tongue guide 192. [00124] The surgical device 100 can be used in conjunction with a neural collar system 200. For example, the neural collar system 200 may include an electrode housing 202, a collar neck ^{HB: 4933-6586-4273.1} 17 204, and a collar 206. The electrode housing 202 can hold a probe 208 that has one or more electrodes 210 configured to couple with a nerve bundle or one or more nerves 212. [00125] The electrode hood 170 may provide a space in the device housing 102 that can receive the electrode housing 202. For example, the electrode hood 170 may have a body in which a slot is formed that is dimensioned to receive the electrode housing 202. The electrode hood 170 may tightly hold the electrode housing 202 until deployment. For example, the slot formed in the electrode hood 170 may be form fitting to the electrode housing 202 with a tight or friction fit. As another non-limiting example, the inner walls 174 of the electrode hood 170 may include grips, barbs, teeth, etc., which can tightly hold the walls of the electrode housing 202. [00126] The slot within the electrode hood 170 may extend from the proximal end of the electrode hood 170 through the distal end of the electrode hood 170 to allow distal movement of the electrode housing 202 through the electrode hood 170 in deployment. The plunger 172 may be positioned proximally adjacent to the slot of the electrode hood 170. The plunger 172 may be sized to fit fully or partially into the slot. The plunger may have a distal surface or wall that abuts a proximal end of the electrode housing 202 when in place. For example, the distal plunger wall 176 may have a complimentary shape of the electrode housing 202 (e.g., concave and convex curves, respectively). When actuated, the plunger wall 176 may put distal pressure on the electrode housing 202 to deploy it through the slot in the electrode hood 170 and into the collar system 200. [00127] When in place, the collar neck 204 may be positioned distal to the electrode hood 170, held in place by the retractable grip hook 180 and stationary grip hook 182. For example, the retractable grip hook 180 may have an arm 184 that extends laterally from the grip hook actuator tendon 162. At the lateral end of the arm 184, the retractable grip hook 180 may have a rounded or barbed hook 186 configured to engage a proximal end of the collar neck 204. The hook 186 may extend distally from the arm 184. [00128] The retractable grip hook 180 is configured to shift proximally by the grip hook release 130 and grip hook actuator tendon 162. The retractable grip hook 180 may be retracted proximally to insert the collar neck 204, then be released distally so that the hook 186 can engage the collar neck 204 with a distal pressure. [00129] The stationary grip hook 182 may be positioned distally from the retractable grip hook 180. The stationary grip hook 182 may include a hook 188 that extends laterally from the device housing 102 and curves proximally. The stationary grip hook 182 may be configured to engage a distal surface of the collar neck 204. In a non-limiting example, the protrusions or ^{HB: 4933-6586-4273.1} 18 hooks (e.g., 186, 188) of the retractable grip hook 180 and stationary grip hook 182 may be aligned along the lateral-medial axis to create opposing force on the collar neck 204 when in place. [00130] The flexible tongue 190 may extend distally from the tongue actuator tendon 164. The tongue guide 192 may extend distally from the device housing 102. The tongue guide 192 may be a curved protrusion with a surface extending from the device housing 102 and curving towards the flexible tongue. The tongue guide 192 may curve laterally from the device forming an inner concave surface 194 that can receive and guide the flexible tongue 190. In use, the flexible tongue 190 may slide along the inner surface 194 of the tongue guide 192. [00131] The flexible tongue 190 may have two lobes. The lobes may be curved or nearly circular bodies. The first lobe 196 may extend distally from the tongue actuator tendon 164. The first lobe 196 may be positioned adjacent to the tongue guide 192, nesting within and abutting the inner concave surface 194. The second lobe 198 may extend laterally from the first lobe 196. The second lobe 198 may also extend slightly distally from the first lobe 196 and may be biased proximally. The outer surface of the second lobe 198 may be configured to facilitate curling or wrapping of the collar 206 around the nerve 212. For example, second lobe 198 may have a smooth outer surface that is rounded. In use, the second lobe 198 may abut an outer surface of the undeployed collar 206a and guide the collar 206 into the deployed position (i.e., 206b). FIG. 2 shows the flexible tongue 190 in several positions along the progression from a first configuration, in which the collar is undeployed (206a), to a second configuration, in which the collar is deployed (206b). [00132] The flexible tongue 190 may be made out of a flexible material that allows for bending of the flexible tongue 190. For example, the flexible tongue 190 may be constructed from plastic, silicone, rubber, nylon, stainless steel or combinations thereof. For example, the flexibility of the material may allow the flexible tongue 190 to bend at the junction between the tongue actuator tendon 164 and the first lobe 196. The flexible tongue 190 may also be configured to bend at the junction between the first lobe 196 and the second lobe 198, for example. [00133] Referring now to FIGS.3-7, the process of deploying the neural collar system 200 is illustrated in one embodiment including six steps. FIG. 3 demonstrates step 1. First, the electrode housing 202 may be placed within the surgical device 300. For example, the electrode housing 202 may be slid proximally into the electrode hood 170 and temporarily fixed into place. In this position, the plunger 172 may be positioned proximally from the electrode housing 202 and may be abutting a proximal surface of the electrode housing 202. ^{HB: 4933-6586-4273.1} 19 [00134] Next, as shown in FIG.4, the retractable grip hook 180 of the surgical device 300 may be retracted into an open position using the grip hook release 130 and grip hook actuator tendon 162. In the retracted or open position, the collar system 200 may be inserted into the surgical instrument 100. The collar system 200 may be placed distally from the electrode hood 170. The stationary grip hook 182 may engage a distal surface of the collar neck 204. The retractable grip hook 180 may be released distally into a closed position to hold the collar neck 204 between the retractable grip hook 180 and the stationary grip hook 182. At this point the collar 206 may be in an open position 206a to receive a nerve 212, multiple nerves, or a nerve bundle. [00135] In step 4, the nerve may be hooked by the collar 206 in its undeployed configuration 206a, as shown in FIG. 5. To hook the nerve 212, the surgical device 100 coupled with the collar system 200 may be moved toward the nerve 212 laterally so that the nerve 212 may enter the open collar 206 while rotating the device circumferentially around the nerve 212. The device may then be moved distally to align the nerve 212 in the proximal end of the collar 206 to partially surround the nerve 212 on the proximal side. For example, control of the surgical device 100 position may be facilitated by the handle 108. [00136] As shown in FIG. 6, step 5 includes deploying the flexible tongue 190 using the tongue actuator 150 and tongue actuator tendon 164, which facilitates distal motion of the flexible tongue 190. As the flexible tongue 190 is pushed distally by the tongue actuator tendon 164, it will slide along the inner surface of the tongue guide 192 and the outer surface of the collar 206 in the distal direction. The flexibility of the tongue 190 may allow for lateral motion of the tongue as it is pushed laterally by the inner surface of the tongue guide 192. [00137] The tongue guide 192 can be shaped to create a circular path of the distal end of the flexible tongue 190. Thus, the movement of the flexible tongue 190 along the tongue guide 192 can cause the collar 206 to curl circumferentially to wrap around the nerve 212. As the first lobe 196 of the flexible tongue 190 slides along the tongue guide 192, the second lobe 198 of the flexible tongue 190 will slide along the outer surface of the collar 206, pressing the collar laterally. Applying force to the collar 206 by the movement of the flexible tongue 190 can cause the collar 206 to wrap around the nerve 212, creating a coiled position (206b) with a circumference that encircles the nerve 212. The collar 206 may have a bias to the coiled or uncoiled position facilitating adjustment of the collar 206 around the nerve or nerve bundle. [00138] After the collar 206 is deployed into the engaged position (i.e., circumferentially wrapped around the nerve 212, 206b), step 6 includes inserting the electrode housing 202 into a slot in the collar neck 204, as shown in FIG.7. The electrode housing 202 may be slid distally ^{HB: 4933-6586-4273.1} 20 into the collar neck 204 by pressing the plunger 172 in a distal direction using the plunger actuator 120 and plunger actuator tendon 160. As the plunger 172 is extended distally, a distal surface of the plunger may apply distal force to a proximal surface of the electrode housing 202. Such pressure will deploy the electrode housing 202 distally into the collar system 200, where the electrodes 210 may embed into the nerve 212, allowing for electrical communication between the nerve 212 and the electrodes 210, thus activating the device for signal transmission to and from the nerve 212. [00139] The collar 206 may be locked into the wrapped position 206b. For example, the collar 206 may include fasteners that can lock the collar 206 in the engaged position with the selected diameter. As a non-limiting example, the fasteners can be activated by the insertion of the electrode housing 202 into the collar system 200. Once locked, the flexible tongue 190 may be released proximally using the tongue actuator 150 and tongue actuator tendon 164. [00140] As shown in FIG.8, an additional step 7 may include that once the collar 206 is in the activated and locked position 206b, the retractable grip hook 180 can be retracted, releasing the collar system 200 from the surgical device 100. The surgical device 100 may be removed, leaving just the collar system 200 fixed in place around the target nerve bundle or nerve 212. A cable other electrical connection can be secured to the collar system 200 to provide electrical communication to the electrodes 210. [00141] FIG.9 shows an example of a system 400, which can be a specific implementation of the various devices and systems described herein. As such, the system 400 pertains and is applicable to the other devices described herein (and vice versa). In some cases, the system 400 can be an implantable neural collar system, similar to the implantable neural collar system. In other cases, the system 400 can be an implantable peripheral nerve system. [00142] As shown in FIG.9, the system 400 comprises a probe 402, a probe housing 404, a support, and a cable 408. The probe 402 and the probe housing 404 can be implemented in a similar manner as the probe and housing as described in the corresponding application U.S. 62/511,101 filed June 29, 2023 and entitled, “Neural Electrode and Related Methods,” which is incorporated by reference in its entirety, including any derivative applications. For example, the probe 402 comprises one or more shanks 410 (e.g., which can be defined as an electrode shank because each shank 410 comprises at least one electrode contact), each of which comprises one or more electrode contacts. Correspondingly, the probe 402 can also include one or more electrode traces and one or more electrical contacts 412. In some cases, each electrode contact is electrically coupled to a respective electrode trace, which is electrically coupled to a respective electrical contact (e.g., of the electrical contacts 412). In some cases, ^{HB: 4933-6586-4273.1} 21 the probe 402 comprises a plurality of electrode shanks, each of which comprises a plurality of electrode contacts, and a plurality of electrode traces each of which electrically couple a given electrode trace of a shank to a corresponding electrical contact of the probe. As shown in FIG. 9, the probe 402 is positioned within the housing 404. For example, the probe housing 404 comprises a recess (or stated a different way a slot) with a hole fluidly coupled to the recess. The hole can be positioned at the bottom of the probe housing 404. The probe 402 can be inserted into the recess of the probe housing 404 and the one or more shanks 410 can extend through the hole and outside of the probe housing 404. In other words, the one or more shanks 410 can be positioned outside of the probe housing 404 (e.g., outside the recess of the probe housing 404), such that the probe housing 404 surrounds and secures a portion of the probe 402 (e.g., to protect the probe 402) while the one or more shanks 410 are free to engage (e.g., penetrate) a nerve of a subject. [00143] In one embodiment, the probe housing 404 comprises a locking feature 414 that can prevent or otherwise block movement of the probe housing 404 (e.g., with the probe 402 positioned therein). For example, as shown in FIG. 9, the locking feature 414 can be implemented as a protrusion, which as described below, engages with a corresponding locking feature of the support 406 to prevent movement of the probe housing 404 relative to the support 406 (e.g., downward translation of the probe housing 404 relative to the view in FIG. 9). In some cases, when the locking feature 414 is implemented as a protrusion, the protrusion can be a locking tooth. For example, the locking tooth can be angled (e.g., can have a triangular side profile) and can be inserted into a recess having a similar shape. In other cases, the locking feature 414 can be a recess, hole, etc., that engages with a corresponding feature of the support 406. In one embodiment, the locking feature 414 comprises a spring (e.g., compression spring, tortional spring, etc.) that biases a protrusion towards a position where the protrusion extends away from the probe housing 404. Similarly, the collar body 416, and in particular, the extension 446 comprises a recess that receives the protrusion, thereby locking the probe housing 404 into the extension 446 (e.g., the slot 452 of the extension 446). Correspondingly, in some cases, the probe housing 404 can be removably coupled to the collar body 416, such as at the extension 446 (e.g., with the spring biased protrusion and recess configuration). [00144] The support can be implemented in different ways, including a similar configuration as the collars described herein or the supports and collars of the corresponding provisional application 62/511,101, and derivative applications thereof, incorporated herein by reference in its entirety. The support can be configured to surround (e.g., entirely or partially) a nerve of a subject (e.g., a peripheral nerve) and can be configured to receive and secure the probe 402 ^{HB: 4933-6586-4273.1} 22 (and probe housing 404) as well as the cable 408. For example, the support comprises a slot with a hole positioned at an end of the slot, in which the slot receives and secures the probe housing 404 with the probe 402 positioned therein. As indicated below, the support will be described as being a collar 406; however, it is appreciated that the support comprises all the features of the collar and can be shaped in different ways as the collar 406. [00145] The collar 406 comprises collar body 416 that can define a bore 418 that can receive a nerve (e.g., a peripheral nerve). The collar body 416 comprises portions 420, 422 and a hinge 424 that can be coupled to the portions 420, 422. Each portion 420, 422 comprises a curve, or stated another way, each portion 420, 422 can be curved. The portions 420, 422 can extend along a longitudinal axis 425 of the collar 406. The longitudinal axis 425 can be perpendicular to a vertical axis 426, which can define distal and proximal directions of the collar 406. Correspondingly, the intersection between the longitudinal axis 425 and the vertical axis 426 can define an origin for a radial axis 428. Further, a circumferential axis 430 can be defined around the longitudinal axis 425. The portions 420, 422 of the collar 406 can span substantially (i.e., deviating from less than or equal to 30 percent from, in this case, a length) the same length (e.g., along the longitudinal axis 425). For example, the length of the portions 420, 422 can be substantially the same. The portions 420, 422 can be coupled to each other, such that when the portions 420, 422 are coupled to each other, the collar 406 is secured to a nerve (e.g., when the nerve is positioned in the bore 418 of the collar 406). [00146] As shown in FIG.9, the portions 420, 422 can be pivotally coupled to each other so as to pivot between an open configuration (e.g., the configuration shown in FIG.9) and a closed configuration. For example, the collar 406 comprises a hinge 424 that can be coupled to the portions 420, 422 so as to allow the portions 420, 422 to pivot about the hinge 424. In some cases, the portion 420 can pivot about the hinge 424 about the longitudinal axis 425, while the portion 422 can pivot about the hinge 424 about the longitudinal axis 425. The hinge 424 can be implemented in different ways. For example, the hinge 424 can be a flexible or otherwise compliant material that can bend to permit pivoting of the portions 420, 422. As another example, the hinge 424 comprises a pin (e.g., a pinned connection) to allow the portion 420 to pivot relative to the portion 422 (or vice versa). In one embodiment, the portions 420, 422 can have substantially the same peripheral shape (e.g., taken from the cross-section at the longitudinal axis 425 of the collar 406). For example, each portion 420, 422 can have a u- shape which can allow the portions 420, 422 to better engage and secure the nerve within the bore 418 of the collar 406 (e.g., which can be defined by the portions 420, 422 of the collar 406). In some cases, and as illustrated in FIG.9, a peripheral distance 432 of the portion 420 ^{HB: 4933-6586-4273.1} 23 can be shorter than a peripheral distance 434 of the portion 422, where each peripheral distance is the length of a line integral that follows the curvature of the respective portion until it terminates at an end. In this way, the portion 422 can wrap around or otherwise surround the portion 420, such that the collar 406 can surround the entire nerve when the nerve is positioned within the collar 406 (e.g., positioned within the bore 418). In some cases, the portion 422 can have different curvatures, which can accommodate securing the portion 422 to the portion 420 and permit adequate bending or compliance of the hinge 424. For example, the portion 422 can have curvature regions 436, 438, each of which can be different, and the curvature region 436 can be positioned above the curvature region 438. In some cases, in the closed configuration, the collar body 416 surrounds the nerve tightly enough to prevent axial translation of the collar body 416 along the nerve, but loose enough to prevent undesired pressure on the nerve. [00147] Although the portions 420, 422 have been described as having a u-shape or being substantially u-shaped, the portions 420, 422 can surround the nerve in other ways. For example, each portion 420, 422 can be circular, such as each being a semi-circle or each having a different arc length. Regardless of the configuration, as described above, the portion 422 can be coupled to and can wrap at least partially around the portion 420 (e.g., with the portion 420, 422 surrounding the nerve). For example, the collar 406 (or broader system 400) comprises a fastener 440 that can secure and lock the collar 406 around the nerve. The fastener 440 can be implemented in different ways. As shown in FIG. 9, the fastener 440 comprises a tooth 442 and a hook 444, in which the hook 444 engages with the tooth 442 to lock the fastener 440. In some cases, and as illustrated, the portion 420 comprises the tooth 442, while the portion 422 comprises the hook 444. However, in other configurations, the portion 422 comprises the tooth 442 and the portion 420 comprises the hook 444. The tooth 442 is positioned at a free end of the portion 420, while the hook 444 is positioned at a free end of the portion 422. More specifically, the tooth 442 can be positioned on an exterior surface the portion 420, opposite an interior surface that can at least partially define the bore 418. In some cases, the portion 420 can be fixed, and the portion 422 can pivot about the hinge 424 towards the portion 420 until the hook 444 engages with the tooth 442 and locks the portion 422 to the portion 420. Although the fastener 440 has been described as being a hook and tooth, the fastener 440 can be implemented as other fasteners including threaded fasteners, hook and loop fasteners, adhesives, magnets (e.g., the portions 420, 422 being magnetically coupled to each other), etc. [00148] In one embodiment, a width or a diameter of the bore 418 can be adjustable so as to permit entry and securement of different sized nerves. For example, the diameter of ^{HB: 4933-6586-4273.1} 24 peripheral nerves can vary, depending on the location the nerve. In particular, as the peripheral nerve emanates from the central nervous system and towards the periphery, the peripheral nerve gets smaller in diameter. Therefore, the collar 406 being adjustable can be advantageous so as to allow the collar 406 to be secured to various sizes of nerves. To that end, as shown in FIG. 9, the fastener 440 can accommodate a plurality of different positions, each of which defines a different width or diameter of the bore 418. For example, the fastener 440 comprises a plurality of teeth (e.g., two, three, four, etc.) with each tooth defining a different locking position that has a different width or diameter of the bore 418. In particular, when the hook 444 engages a first tooth of the plurality of teeth, the collar 406 is locked in a first closed configuration where the bore 418 has a first width. Correspondingly, when the 444 engages a second tooth of the plurality of teeth, the collar 406 is locked in a second closed configuration where the bore 418 has a second width. In this case, the second width can be different than the first width (e.g., larger than the first width). [00149] In one embodiment, the collar body 416 comprises an extension 446. The extension 446 can be positioned at a top of the collar body 416, such that the extension 446 is positioned above the nerve when the nerve is positioned within the bore 418. In some cases, the extension 446 can be coupled to the first portion 420 of the collar body 416 and can extend above the first portion 420. For example, as shown in FIG.9, the extension 446 can be integrally formed with the portion 420 of the collar body 416 (e.g., the components can form a single monolithic component). In some cases, the extension 446 can separate the portion 420 into two sections, with a first section being positioned on one side of the extension 446 and another section being positioned on an opposing side of the extension 446, where each side is a longitudinal side. Therefore, each section of the portion 420 can be curved, can have a u-shape, semi-circular shape, partial circular shape, etc. In some cases, the extension 446 can bisect the portion 420. [00150] The extension 446 comprises seats 448, 450, positioned on opposite sides of the extension 446 (e.g., opposing transverse sides, in a direction transverse to the longitudinal axis 425). For example, the nerve or bore 418 can be positioned between the seats 448, 450. The seats 448, 450 can be angled, beveled, etc., which can extend downwardly towards the nerve. Each seat 448, 450 can receive a corresponding feature of the cable 408 to couple the cable 408 to the extension 446. The collar body 416, and in particular the extension 446, comprises a slot 452 directed into the extension 446 that can receive the probe housing 404 to secure the probe housing 404 therein (e.g., with the probe 402 secured by the probe housing 404). Further, the collar body 416, and again, more specifically the extension 446 comprises a hole 454 directed through the collar body 416. The hole 454 can provide access, such that the one or ^{HB: 4933-6586-4273.1} 25 more shanks 410 of the probe 402 can extend through the hole 454 and engage with to be electrically coupled to a nerve (e.g., a peripheral nerve) secured, trapped, etc., by the collar 406. In some cases, and as shown in FIG.9, the hole 454 can be fluidly coupled to the slot 452 and can be positioned at an end (e.g., a bottom end) of the slot 452. In this way, the slot 452 can secure the probe housing 404, while the one or more shanks 410 can extend through the hole 454 into the bore 418 (e.g., to engage, penetrate, etc., the nerve therein). In some cases, advantageously, the slot 452 can be oriented such that a width extends substantially along a transverse axis of the collar 406 (e.g., perpendicular to the longitudinal axis 425, such that the transverse axis straddles the longitudinal axis 425), which can then ensure that each shank is positioned at a different transverse location along a nerve thereby allowing for the collection of more unique nerve signals (e.g., all the shanks being within substantially same axial cross section of the nerve). [00151] In one embodiment, the collar 416 comprises a protrusion 456. Similarly to the extension 446, the protrusion 456 can be positioned on a top of the collar body 416, such that the protrusion 456 extends above the bore 418 and above the nerve positioned therein. As shown in FIG. 9, the protrusion 456 can extend above the extension 446. For example, the protrusion 456 extends away from and above the collar body 416 including the seats 448, 450 of the extension 446. In some cases, the protrusion 456 can be coupled to the extension 446. In other cases, the protrusion 456 can be integrally formed with the extension 446 (e.g., the protrusion 456 and the extension 446 forming a single monolithic component). In some configurations, a wall of the protrusion 456 can at least partially define the slot 452. In this way, the protrusion 456 can support the probe housing 404 (e.g., with the probe 402 therein). For example, the probe housing 404 can contact the protrusion 456 (e.g., at a wall thereof), when the probe housing 404 (and probe 402) is positioned within the slot 452. [00152] In one embodiment, the collar body 416, and in particular the extension 446, comprises an engagement feature 458. The engagement feature 458 can interface with an arm of a device (e.g., a surgical device, such as the surgical device 300) that can engage with the collar 406 and can close the collar 406 around a nerve. More specifically, the engagement feature 458 can increase the friction between the collar body 416 (and particular the extension 446) and an arm of a device so as to ensure that the arm maintains contact with the collar body 416 (e.g., at the extension 446) and prevents slipping or disengagement with the arm of the device. The engagement feature 458 can be implemented in different ways. For example, the engagement feature can be a recess, a hole, a rough surface, a number of small protrusions emanating from the surface of the collar body 416 at the location, etc. Although the ^{HB: 4933-6586-4273.1} 26 engagement feature 458 is shown on one side of the extension 446, the other side of the extension 446 comprises an engagement feature (e.g., implemented in a similar was to the engagement feature 458). [00153] As shown in FIG.9, the collar body 416, and in particular the portion 422 comprises a hole 460, or in some cases a recess, that can receive the one or more shanks 410 of the probe 402, which can be implemented in a similar way as the electrode tip slot 52 of the collar 16. For example, each tip (e.g., the sharp termination point of a free end of a shank) of each shank 410 can be received in the hole 460, which can prevent the tips from penetrating other tissues. As described with reference to slot 52, although the hole 460 has been described has being a recess, in some cases, the collar body 416 comprises a plurality of recesses (or holes) each of which can receive a respective shank of a plurality of shanks of the probe 402. [00154] In some configurations, and as described in more detail below, the cable 408 comprises a cable boot 462 coupled to and positioned at an end of the cable 408 (e.g., a terminal end of the cable 408 that includes one or more wires therein). The cable boot 462 can be coupled to (and removably coupled) to the collar body 416, and in particular, the extension 446 and protrusion 456 of collar body 416. More specifically, when the probe housing 404 with the probe 402 therein is positioned within the slot 452 of the collar body 416, the cable boot 462 can be coupled to the collar body 416 and can at least partially surround the probe housing 404. In this way, the cable boot 462 can lock the probe housing 404 into the collar body 416 thereby constraining relative movement between the probe housing 404 and the cable boot 462. [00155] FIG.10 shows an example of a cross-section of the system 400 with the collar in a closed configuration around the nerve (e.g., a nerve bundle) and prior to the insertion of the probe into the collar. In particular, the collar 406 surrounds the entire circumferential extent of a nerve bundle 464. For example, the portion 422 partially overlaps with the portion 420, where the hook 444 is engaged with the corresponding tooth 442 to lock the collar 406 into a closed position, such as the one shown in FIG.10. In some cases, the nerve bundle 464 (e.g., a peripheral nerve bundle), and in particular a top of the nerve bundle 464, can extend at least partially through the hole 454 in the extension 446. In this way, the nerve bundle 464 can be further secured by the collar 406 and can ensure that the one or more shanks 410 engage (e.g., penetrate) the peripheral nerve bundle 464). In some cases, when in the closed configuration, the hinge 424 flexes inward to contact opposing portions of the hinge 424 (e.g., the hinge 424 pressing against itself). As illustrated in FIG. 10, the probe housing 404 with the probe 402 therein is aligned with the slot 452 for insertion therein. ^{HB: 4933-6586-4273.1} 27 [00156] In one embodiment, the collar body 416, and more specifically, the extension 446 and the protrusion 456 of the collar body 416, comprises a slot, which can vertically extend down towards the nerve bundle 464 (or towards the portions 420, 422). This slot can receive the locking feature 414 of the probe housing 404, when, for example, the locking feature is implemented as a locking tooth. When the probe housing 404 is inserted into the slot 452 of the collar 406, the locking feature 414 of the probe housing 404 is received in the slot. In this way, side to side movement (e.g., in a transverse direction) of the probe housing 404 relative to the collar 406 is blocked by the engagement between the locking feature 414 of the probe housing 404 and the collar 406. Although the slot is illustrated as being rectangular, the slot can be implemented in different shapes. Further, although the collar body 416 is shown as having a slot, this slot can be replaced with a complementary feature of the locking feature 414. For example, if the locking feature 414 is implemented as a recess, the slot can be implemented as a protrusion. Stated another way, the collar 406 comprises the locking feature 414 that engages with a corresponding feature of the probe housing 404 to secure the probe housing 404 relative to the collar 406. [00157] FIG.11 shows an example of a cross-section of the system 400 with the collar in a closed configuration around the nerve (e.g., a nerve bundle) and with the probe inserted into the collar. In particular, the probe housing 404 with the probe 402 therein is inserted or otherwise positioned within the slot 452 of the collar body 416 (and more specifically the extension 446). At this point, the one or more shanks 410 of the probe 402 extend through the hole 454 and puncture or otherwise are inserted into the nerve bundle 464. For example, as shown in FIG.11, the probe 402 including four shanks extend across a cross-section (e.g., an axial cross-section) of the nerve bundle 464, which can allow each electrode contact (of a plurality or many electrode contacts) on each shank to interface or electrically couple with a different nerve fiber, thereby collecting more unique nerve signals or allowing the different nerve fibers to be selectively excited. In some cases, and as illustrated in FIG.11, each terminal end tip of the one or more shanks 410 can be inserted into the hole 460, as described above. In some configurations, a portion (e.g., a top portion) of the probe housing 404 (and the probe 402) can be positioned above each seat 448, 450. Further, this portion of the probe housing 404 can be flush with the protrusion 456. For example, a top of the probe housing 404 is flush with a corresponding top of the protrusion 456. [00158] FIG.12 shows an example of a cross-section of the system 400 with the collar in a closed configuration around the nerve (e.g., a nerve bundle), with the probe inserted into the collar, and with the cable boot coupled to the collar. As shown in FIG.12, the cable boot 462 ^{HB: 4933-6586-4273.1} 28 comprises arms 466, 468 which can extend away from the cable 408. The arms 466, 468 can be positioned on opposing sides of the cable 408, such that the cable 408 is positioned between the arms 466, 468. In this way, the arms 466, 468 and the cable boot 462 can form a u-shape. As described above, the cable boot 462 can be coupled to the collar 406, and more specially the collar body 416. For example, the system 400 comprises one or more fasteners that are configured to couple the cable boot 462 to the collar 406. As a more specific example, the system 400 comprises fasteners 470, 472, each of which are configured to fasten, couple, etc., the cable boot 462 to the collar 406. In some cases, each fastener 470, 472 can be formed by part of the cable boot 462 and the collar body 416. For example, the fastener 470 comprises a tooth 474 on the arm 468, while the fastener 472 comprises a tooth 476 at the arm 468. The teeth 474, 476 can face each other, with the tooth 474 extending towards the probe housing 404 and with the tooth 476 extending towards the probe housing 404. The teeth 474, 476 can be received in a corresponding recess of the collar body 416 to couple the teeth 474, 476 to the collar body 416. For example, each fastener 470, 472 comprises a respective recess 478, 480. For example, the collar body 416, and specifically the protrusion 456, comprises recesses 478, 480, where the tooth 474 is inserted into the recess 478 and where the tooth 476 is inserted into the recess 480. The engagement between the teeth 474, 476 and corresponding recesses 478, 480 lock the cable boot 462 to the collar body 416, by, for example, a snap-fit connection between the two components. Although the fasteners 470, 472 have been described as being a protrusion on an arm and a recess of the collar body, these can be implemented in a vice versa way (e.g., a protrusion on collar body and a recess on an arm). [00159] In one embodiment, the engagement between the cable boot 462 and the collar body 416 can ensure that the probe 402 is prevented or otherwise blocked from moving relative to the nerve bundle 464. For example, the probe housing 404 can surround the probe 402, the collar body 416 (e.g., the extension 446 and the protrusion 456) can surround the probe housing 404 (e.g., with the probe 402 therein), and the cable boot 462 can surround the probe housing 404 and a portion of the collar body 416 (e.g., the protrusion 456, such as with the arms 466, 468, the extension 446, etc.). This nesting configuration can ensure that the probe 402 is secured relative to the nerve bundle 464 (e.g., the probe 402 does not slide out of the slot 452). To that end, each arm 466, 468 can extend downwardly (e.g., towards the nerve bundle 464), can engage and can contact the respective seats 448, 450 of the extension 446, which can provide further support for the cable boot 462. In one embodiment, and as illustrated in FIG. 12, the cable boot 462, the protrusion 456 and the extension 446 can be flush (e.g., a top of each of these components can be flush). Further, the outer periphery of the cable boot 462, the ^{HB: 4933-6586-4273.1} 29 protrusion 456 and the extension 446 when assembly can be smooth, free of sharp edges, etc., so as to minimize inadvertent rection with surrounding tissue. [00160] Although not shown in FIG.12, when the cable boot 462 couples to the collar body 416 and the probe housing 404, the cable 408 electrically couples to the probe 402. For example, one or more electrical contacts of the cable 408 are brought into engagement with the one or more corresponding electrical contacts 412 positioned on a top of the probe 402. In this way, electrical signals can be transmitted from the cable 408 to the probe 402 (e.g., for nerve stimulation) or electrical signals can be transmitted from the probe 402 to the cable 408 (e.g., for nerve signal interpretation). [00161] In one embodiment, portions of or the entire system 400 can be implanted in the subject. For example, the probe 402, probe housing 404, collar 406, and cable 408 (e.g., including the cable boot 462) can be implanted within the subject, for example, under the skin of the subject. This implantation of the system 400 can allow for prolonged usage of the system 400. In other configurations, the implantation of the system 400 can be temporary, such as during harvesting of neural signals. To that end, some or all of the components of the system 400 that are coupled together can be removably coupled together. For example, the cable boot 462 can be removably coupled from the collar body 416 (e.g., at the protrusion 456 of the collar body 416) and the probe housing 404 can be removably coupled to the collar body 416 (e.g., by removing the probe housing 404 (e.g., with the probe therein 402) from the slot 452 of the collar body 416. [00162] FIG. 13 shows a side view schematic of an example of a device 500 in an open configuration, which can be a surgical device and can be implemented in a similar manner as the device 100. As described in detail below, the device 500 can be configured to deploy, insert, secure, etc., the system 400, and more specifically, the collar 416 of the system 400 and the probe 402 (e.g., the probe housing 404). [00163] The device 500 comprises a body 502, an arm 504, actuators 506, 508, and a hook 511. The body 502 comprises and can support the components for the device 500, and therefore can be made of structurally sound, rigid material. For example, the body 502 can be formed out of a polymer (e.g., a plastic), a metal, etc. The body 502 comprises a base 510 and a shaft 512 coupled to and extending away (e.g., downwardly from) the base 510. As shown in FIG. 13, the base 510 and the shaft 512 can have an L-shape (e.g., substantially an L-shape), in which case the base 510 and the shaft 512 can be substantially perpendicular to each other. For example, the shaft 512 has a longitudinal dimension (e.g., up and down relative to the view in FIG.13) that is larger than a longitudinal dimension of the base 510 (e.g., left to right relative ^{HB: 4933-6586-4273.1} 30 to the view in FIG.13). In some configurations, the longitudinal dimension of the shaft 512 is substantially larger than the longitudinal dimension of the base 510. In this way, the shaft 512 of the device can interact with tissues in a less invasive manner. To that end, the shaft 512 has a thickness (or width) that is smaller (e.g., substantially smaller) than the thickness (or width) of the base 510. In some configurations, the body 502 can be shaped similarly to a laparoscopic surgical instrument’s outside peripheral shape. In some cases, the base 510, including portions thereof, can be configured to be grasped by a hand. Therefore, the base 510 comprises one or more finger ridges, a grip surface (e.g., a polymer), etc. [00164] As shown in FIG. 13, the body 502 comprises sections 514, 516, which can be complementary with each other. For example, the body 502 can be separated into the sections 514, 516, in which the section 516 can be positioned above the section 514 (e.g., with the section 514 positioned below the section 516). In an open configuration (e.g., a non- deployment configuration), which is shown in FIG. 13, the sections 514, 516 are separated from each other by a gap 518. In operation, including when moving from the open configuration to a closed configuration (e.g., a deployment configuration), the section 514 moves towards the section 516 (e.g., with the section 516 being stationary or fixed relative to the section 514) until the sections 514, 516 move closer to each other (e.g., a top edge of the section 514 moves closer to a bottom edge of the section 516) and the gap 518 closes partially (or completely, such as in configurations where only the collar is to be deployed). In this way, as described below, the sections 514, 516 can drive the actuator 506 (e.g., cause the actuator 506 to move). In one embodiment, a protrusion 520 can be received within the body 502. In particular, in the open configuration, the protrusion 520 can coupled to the section 516 and can be partially received within the section 514. In this way, the sections 514, 516 can be prevented from separating from each other. Further, as the device 500 moves away from the open configuration (and towards the closed configuration), the protrusion 520 can be further received within the section 514 (e.g., a recess thereof). [00165] In one embodiment, the sections 514, 516 can be biased away from each other, using for example, a spring (e.g., a spring coupled between the sections 514, 516, which can be a compression spring). To that end, the protrusion 520 comprises a spring, such as a compression spring, that can be coupled between the sections 514, 516. The spring can be advantageous in that the sections 514, 516 can be biased away from each other. In that way, only when the sections 514, 516 are actively forced together (e.g., with the grip strength of a hand) does the hook 511 retract inward, or is otherwise pulled towards the base 512. Therefore, and advantageously, when the sections 514, 516 are released, the hook 511 is forced outward (e.g., ^{HB: 4933-6586-4273.1} 31 pushed in an opposite direction away from the base 512), away from the collar 406. Thus, as described below, when the device 500 locks the collar 406, releasing of the sections 514, 516 can automatically force the hook 511 away and out of engagement with the closed collar 406 to disengage the device from the collar 406 (e.g., after the procedure is completed). In one embodiment, the actuator 506 comprises this spring. [00166] As shown in FIG.13, the sections 514, 516 not only can extend through the base 510, but can also extend through the shaft 512. In some configurations, the gap 518 positioned between the sections 514, 516 at the base 510 can be smaller (e.g., significantly smaller) than the gap 518 positioned between the sections 514, 516 at the shaft 512. In this way, the translational movement between the sections 514, 516 at the shaft 512 corresponds to sliding of these sections 514, 516 relative to each other. In one embodiment, the arm 504 is configured to engage (e.g., contact) the collar 406 and to force the collar 406 to lock around itself and a nerve (e.g., a peripheral nerve) therein. In some configurations, and as described in more detail below, the arm 504 comprises one or more fingers that can engage the collar 406. [00167] In one embodiment, the actuator 506 can drive movement of the hook 511 to cause the collar 406 to close and lock around itself. For example, as shown in FIG.13, the hook 511 can be coupled to the body 502, and more specifically, can be coupled to the section 514 of the body 502. The hook 511 can extend downward, away from the body 502, past the arm 504 (e.g., a free end of the arm 504 ). In other words, the hook 511 can be coupled to the shaft 512 of the body 502 at a free end of the shaft 512 (e.g., opposite to the location in which the base 510 is coupled to the shaft 512). In this way, the collar 406 can be positioned between and supported by the hook 511 and the arm 504. In some cases, the hook 511 (e.g., a portion thereof), can extend substantially parallel to a longitudinal dimension of the base 510. Further, a free end of the hook 511 (e.g., coupled to the portion) can deflect upwardly towards the base 510 of the body 502. The actuator 506 can be implemented as simply being the sections 514, 516 because the separation of the section 514, 516 can drive movement of the hook 511. For example, as the section 514 moves towards the section 516, the hook 511 also moves in the same direction as the section 514. More specifically, the section 514 translates upwardly towards the section 516, and the hook 511 correspondingly moves towards the arm 504 (e.g., decreasing a distance between the arm 504 and the hook 511). This movement can cause the collar 406 to lock around itself thereby securing the nerve (e.g., peripheral nerve) therein. For example, in the open configuration shown in FIG. 13, in which the portion 420 of the collar 406 is secured by the arm 504 (e.g., the arm 504 positioned on top of the portion 420 of the collar 406) and where the portion 422 of the collar 406 is secured by the section hook 511 (e.g., ^{HB: 4933-6586-4273.1} 32 the hook 511 positioned under the portion 422 of the collar 406), the hook 511 is moved towards the arm 504 which pushes the portion 422 of the collar 406 towards the portion 420 of the collar 406 (e.g., while pivoting the portion 422 about the hinge 424) until the portion 422 of the collar 406 locks around the portion 420 of the collar 406. Therefore, the arm 504 can be substantially stationary during locking of the collar 406 around a nerve. [00168] In one embodiment, and as described in more detail below, the actuator 508 can drive insertion of the probe 402, and more specifically the probe housing 404 into the collar 406. For example, the actuator 508 can extend to contact the probe housing 404 (e.g., with the probe 402 therein) and can push the probe housing 404 into the slot 452 of the collar 406, until, for example, the probe housing 404 is secured within the collar 406 (e.g., the extension 446 of the collar 406) and the one or more shanks 410 of the probe 402 are inserted (e.g., puncture) the nerve (e.g., peripheral nerve) that the device 500 has caused the collar 406 to close around. [00169] FIG. 14 shows an isometric view of a schematic of the device 500 in the open configuration, with the device 500 supporting the collar 406 and with the collar 406 surrounding the nerve 464. [00170] FIG. 15 shows an isometric view of a model of the device 500 in the open configuration, with the device 500 supporting the collar 406. [00171] FIG. 16 shows a zoomed in isometric view of the model of the device 500 in the open configuration, detailing the arm 504. As shown in FIG.16, the arm 504 can be coupled to the body 502, and more specifically, can be coupled to the section 516 of the body 502 (e.g., at the shaft 512, such as a free end thereof). In one embodiment, the section 516 (e.g., a free end of the section 516, such as at the shaft 512) comprises a channel 522 that can receive at least a portion of the hook 511. In particular, a base of the hook 511 (e.g., a substantially linear portion that extends substantially parallel to the shaft 512 of the body 502) can be inserted into the channel 522. In this way, as the hook 511 is pulled towards the base 510, the hook 511 can slide along the channel 522. In one embodiment, an opposing side of the section 516 comprises a channel to receive a corresponding portion of the hook 511. In some cases, this can facilitate the arm 504 being positioned between opposing sides of the hook 511. For example, the hook 511 comprises a hole 523 and at least a portion of the arm 504 can extend through the hole 523 towards the free end of the hook 511. In some cases, and as shown, the arm 504 can be angled towards the free end of the hook 511 and a portion of the arm 504 that is angled can extend through the hole 523 towards the free end of the hook 511. [00172] As shown in FIG. 16, the arm 504 comprises a base 524 coupled to fingers 526, 528. Each finger 526, 528 can be symmetrical relative to an axis and thus each finger 526, 528 ^{HB: 4933-6586-4273.1} 33 can be implemented in a similar manner. Therefore, although the finger 528 will only be described in detail, the description of the finger 528 is applicable to the finger 526. The finger 528 comprises extensions 530, 532, and a recess 534. The recess 534 is positioned between the extensions 530, 532, such that the extensions 530, 532 are positioned on opposing sides of the finger 526. Although the recess 534 is illustrated as being rectangular, in other configurations, the recess 534 can have other shapes. Each extension 530, 532 comprises a respective protrusion 536, 538 that extends towards the opposing finger. For example, the protrusions 536, 538 can extend (in the same direction) towards the finger 526, while the protrusions on the finger 526 can extend (in the same direction) towards the finger 528. The finger 528 can also include a projection 540, that can, in a similar way to the protrusions 536, 538 can extend towards the opposing finger, in this case the finger 526. Although the projection 540 is shown as having a curved surface and being partially circular (e.g., being a quarter circle), the projection 540 can have other shapes, such as a semi-circle, etc. In some cases, the curved surface of the projection 540 can face the opposing finger, again, in this case, the finger 526. As shown in FIG.16, the projection 540 can be positioned between the extensions 530, 532. Although the arm 504 has been described as having two fingers 526,528, in other configurations, the arm 504 can have one finger, a single finger, such as the finger 526. [00173] As will be described in more detail below, each finger 526, 528 can engage a portion of the collar 406. More specifically, each finger 526, 528 can engage the extension 446 of the collar 406, in which each finger 526, 528 can be positioned on an opposing side of the extension 446. In some cases, this can be advantageous in that having the fingers 526, 528 engage both sides of the extension 446 of the collar 406 can stabilize the collar 406 and can prevent the collar 406 from undesirably rotating or pivoting during deployment of the collar 406. Further, the presence of the extensions (and recesses) can be advantageous in that the collar 406 and be positioned within the recess with the extensions contacting opposing portions of the collar 406 to stabilize the collar 406 during deployment. Each finger 526, 528 (or more generally a portion of the arm 504 that engages with the collar 406) can be flexible. For example, as described in more detail below, each finger 526, 528 can deflect away from the collar 406 (e.g., the extension 446 of the collar 406) or stated a different away each finger 526, 528 can deflect in a direction away from the opposing finger. [00174] In one embodiment, each protrusion of each finger 526, 528 can engage with a corresponding feature of the collar 406. As described above, the collar 406 comprises an engagement feature 458. This engagement feature 458 can engage with a corresponding feature of a finger of the arm 504 (e.g., a protrusion). For example, when the engagement feature 458 ^{HB: 4933-6586-4273.1} 34 is implemented as a hole or a recess, the engagement feature 458 can receive the protrusion of the finger 528. This engagement can ensure that the fingers 526, 528 remain in contact with the collar 406 during closure of the collar 406, insertion of the probe, etc. In some cases, the collar 406, and more specifically the extension 446 of the collar 406 comprises four engagement features, two positioned on opposing sides of the extension 446. In this way, two engagement features (e.g., implemented as the engagement feature 458) can interface with the respective protrusions 536, 538 of the finger 528, while the other two engagement features can interface with respective protrusions of the finger 526. Although the fingers 526, 528 have been described as including protrusions, in other configurations, each protrusion can be replaced with an engagement feature that is complementary with the engagement feature of the collar 406 (e.g., the protrusion of the finger replaced with a recess and the recess of the collar being replaced with a protrusion). Similarly, in some cases, the fingers 526, 528 comprises respective engagement features (e.g., a rough surface) and the collar can lack an engagement feature (and vice versa). In some cases, each engagement feature of a finger and of the collar can be a roughened surface. [00175] FIG. 17 shows a zoomed in side view of a model of the device 500 in the open configuration, detailing the arm 504 and the hook 511, with the arm 504 and the hook 511 supporting the collar 406, while FIG.18 shows a zoomed in opposing side view of the model of the device 500 in the open configuration, detailing the arm 504 and the hook 511, with the arm 504 and the hook 511 supporting the collar 406. As shown in FIG.17, the finger 528 can engage the portion 420 of the collar 406. More specifically, the finger 528 can engage a first section of the portion 420 of the collar 406 (e.g., while the finger 526 can engage the opposing section of the portion 420 of the collar 406), where the portion 420 (e.g., at the section) can be positioned within the recess 534 and with the extensions 528, 530 engaging opposing sides of the section of the portion 420. As shown in FIG.18, the finger 526 can engage the collar 406 in a similar way to the finger 528. For example, the finger 526 can engage the opposite section of the portion 420 of the collar 406, including with the portion 420 (e.g., at the section) being positioned within the recess of the finger 526 and with the extensions of the finger 526 contacting opposing sides of the portion 420. As shown in FIG.18, the protrusion 456 of the collar 406 can be positioned between the fingers 526, 528 with the protrusion 456 being positioned away from the extensions of the fingers 526, 528. [00176] FIG. 19 shows an isometric view of a schematic of the device 500 in the closed configuration, with the device 500 supporting the collar 406 and with the collar 406 surrounding the nerve 464. ^{HB: 4933-6586-4273.1} 35 [00177] FIG. 20 shows a side view of the model of the device 500 in the closed configuration, with the device 500 supporting the collar 406 and with the collar 406 closed. [00178] FIG.21 shows a bottom zoomed in view of the model of the device 500 in the closed configuration, with the device 500 supporting the collar 406 closed. As shown in FIG.21, each finger 526, 528 engages with (e.g., contacts) an opposing side of the extension 446 of the collar 406. Further, each extension of each finger 526, 528 can at least partially surround the extension 446. In this way, the fingers 526, 528 can ensure that the arm 504 is secured to the collar 406 and that the arm 504 does not inadvertently disengage with the collar 406 during closing of the collar 406 (e.g., by the hook 511 being pulled towards the base 510 of the body 502). In some cases, the protrusion 456 can extend above the extensions of the finger 526 and at least a portion of the protrusion 456 can contact the finger 526. [00179] FIG. 22 shows a zoomed in isometric view of the model of the device 500 in the closed configuration, with the device 500 supporting the collar 406 and the collar 406 closed. [00180] FIG.23 shows a zoomed in front view of the model of the device 500 in the closed configuration, with the device 500 supporting the collar 406 and the collar 406 closed. [00181] FIG. 24 shows a zoomed in front view of the schematic of the device 500 in the closed configuration, with the device 500 supporting the collar 406 and the collar 406 closed. [00182] FIG.25 shows a cross-sectional view of a schematic of the device 500 in the open configuration, with the device 500 supporting the collar 406 with the collar 406 opened. The device 500 comprises a channel 542 and a plunger 544. In some cases, and as illustrated, the body 502 comprises the channel 542, with the channel 542 extending through the shaft 512. In this way, the actuator 508 which can be coupled to the plunger 544 has a path to transmit downward movement into movement of the plunger 544. In some cases, the channel 542 can be positioned within an extension 546 of the shaft 512, in which the extension 546 can be coupled to the shaft 512 (e.g., at a free end of the shaft 512). A portion of the extension 546 (e.g., a free end of the extension 546) can be substantially parallel to the arm 504. For example, the extension 546 can be positioned between the fingers 526, 528 of the arm 504. Correspondingly, then, the channel 542 can be positioned between the fingers 526, 528 of the arm 504. In this way, as described below, the plunger 544 can insert the probe housing 404 into the slot 452 of the collar 406 while the fingers 526, 528 support and engage the collar 406. In some cases, the extension 546 and the channel 542 can be positioned within the section 516 of the body 502, for example, because the channel 542 and extension 546 can be fixed to allow deployment of the collar 406 and allow insertion of the probe 402. ^{HB: 4933-6586-4273.1} 36 [00183] As shown in FIG. 25, the plunger 544 can be positioned within the channel 542 above the probe housing 404 with the probe therein 402 (e.g., the probe housing 404 can be positioned entirely within the extension 546, which can facilitate insertion because the probe housing 404 does not then have to traverse corners or turns in the channel 542). Correspondingly, the plunger 544 can be positioned within the shaft 512 and can be positioned within the extension 546. The plunger 544 can be shaped as a hook with an end that is flat and substantially perpendicular to the longitudinal axis of the extension 546. This hook shape can be advantageous in that it can allow the plunger 544 to traverse an angle, corner, turn, deviation, etc., in the channel 542. In other words, when the plunger 544 is pushed or otherwise forced towards and with the plunger 544 having the hook shape, an end 548 of the plunger 544 (e.g., which can be substantially flat) can translate within the extension 546. In some cases, the end 548 of the plunger 544 can be positioned within the channel 542 at the extension 546 before the probe housing 404 is inserted into the collar 406 and before the collar 406 is closed. [00184] In some configurations, the plunger 544 can be coupled to the actuator 508. In this way, the actuator 508 can drive advancing of the plunger 544 along the channel 542. More specifically, at least a portion of the actuator 508 can be positioned within the channel 542. In this way, as the actuator 508 is extended towards the hook 511, arm 504, etc., the actuator 508 pushes the plunger 544 downwards further along the channel 542 towards the collar 406, the hook 511, etc. In some cases, a portion of the actuator 508 can extend above the body 502 and specifically above the shaft 512 and above the base 510. Further, this portion of the actuator 508 can be positioned outside of the body 502. In this way, the actuator 508 can be more unconstrained and larger translational movements can be realized by the actuator 508. [00185] In one embodiment, when the actuator 506 is advanced (e.g., the sections 514, 516 are brought closer together) the hook 511 is pulled upwardly, for example, towards the base 510, arm 504, etc., of the device 500 to force the portions 420, 422 of the collar 406 to close against each other and lock around a nerve, such as a peripheral nerve. At this point, the actuator 508 can extend to force the plunger 544 further along the channel 542 until the end 548 of the plunger 544 contacts the probe housing 404 (e.g., at a cut away of the probe housing 404) to insert the probe housing 404 out through a hole 550 of the extension 546 and into the slot 452 of the collar 406 thereby inserting the one or more shanks 410 of the probe 402 into the nerve secured by the collar 406. In one embodiment, and as illustrated, the hole 550 can be positioned at an end of the extension 546, can be fluidly coupled to the channel 542, and can be aligned with the slot 452 of the collar 406. Although the actuators 506, 508 can independently move, for example, to pull the hook 511 (e.g., thereby closing the collar 406) ^{HB: 4933-6586-4273.1} 37 and to extend the plunger 544 (e.g., to insert the probe housing 404 into the collar 406), the actuators 506, 508 can be coupled together so as to dependently move or otherwise move together. For example, the actuator 508 can be coupled to the actuator 506 (e.g., the section 514 of the body 502). In this way, as the sections 514, 516 are brought together, the section 514 can simultaneously force the actuator 508 to extend thereby pushing the plunger 544, which can then cause simultaneous closing of the collar 406 and insertion of the probe housing 404 into the collar 406. This can be advantageous in that a user needs only to grasp and close the sections 514, 516 to simultaneously close the collar and insert the probe, which can make deployment less complicated. [00186] FIG.26 shows a cross-sectional view of a schematic of the device 500 in the closed configuration, with the device 500 supporting the collar 406, with the collar 406 closed around the nerve 464, and with the probe 402 inserted into collar 406. [00187] FIG.27 shows a cross-sectional isometric view of a schematic of the device 500 in the closed configuration, with the device 500 supporting the collar 406, with the collar 406 closed around the nerve 464, and with the probe 402 inserted into collar 406. [00188] FIG.28 shows a side view of a model of the device 500 in the closed configuration, with the device 500 supporting the collar 406, with the collar 406 closed, and with the probe 402 inserted into collar 406. [00189] FIG. 29 shows a zoomed in isometric view of a model of the device 500 in the closed configuration, with the device 500 supporting the collar 406, with the collar 406 closed, and with the probe 402 inserted into collar 406. [00190] FIG.30 shows a top view of the model of the device 500 in the closed configuration without the collar 406, but with the probe 402 in an inserted position. [00191] FIG.31 shows a top view of the model of the device 500 in the closed configuration with the collar 406 closed, and with the probe 402 inserted into the collar 406. [00192] FIG.32A shows an isometric view of a schematic of the device 500 with the collar 406 in the closed position and prior to insertion of the probe 402 into the collar 406, while FIG.32B shows an isometric view of a schematic of the device 500 with the collar 406 in the closed position and after insertion of the probe 402 into the collar 406. As shown in FIG.32, the finger 528 engages the collar 406 (e.g., at the extension 446 of the collar 406) and secures the collar 406 during insertion of the probe housing 404 (e.g., with the probe 402 therein) into the slot 452 of the collar 406. After the probe housing 404 is inserted into the collar 406, the actuator 506 is further advanced (e.g., the sections 514, 516 are advanced closer together, such as by further tightening a user’s hand) this further forces the arm 504 further downward, which ^{HB: 4933-6586-4273.1} 38 causes the arm 504 to release engagement with the collar 406, such as at the extension 446 of the collar 406. More specifically, each finger 526, 528 is forced downward until at least one of the fingers 526, 528 deflects away (e.g., bends away) from the collar 406 and disengages the collar 406 (e.g., at the extension 446 of the collar 406). Still more specifically, each finger 526, 528 comprises interfering geometry that when the interfering geometry contacts the collar 406, the interfering geometry pushes or otherwise forces the respective finger to disengage the collar 406. In some cases, this interfering geometry can be implemented as a projection (e.g., the projection 540 of the finger 528). In this way, the finger 528 is pushed further downward until the projection 540 contacts the collar 406 (e.g., the extension 446), at which point the finger 528 deflects. Although FIG.32B illustrates only the finger 528 deflecting, the finger 526 can also deflect in a similar manner as the finger 528. Further, although the interfering geometry was described as being on a finger, in other cases, the collar 406, and more specifically the extension 446 of the collar 406 comprises the interfering geometry (e.g., a projection) to force deflection of the corresponding finger. [00193] FIG.33A shows an isometric view of a schematic of the device 500 with the collar 406 in the closed position, after insertion of the probe 402 into the collar 406, and after deflection of the finger 528 of the arm 504 after further actuation of the actuator 506. [00194] FIG.33B shows a top view of a schematic of the device 500 with the collar 406 in the closed position and after deflection of the finger 528 of the arm 504 after further actuation of the actuator 506. [00195] FIG.34 shows a bottom view of a schematic of the device 500 with the collar 406 in the closed position, after insertion of the probe 402 into the collar 406, and after deflection of the finger 528 of the arm 504 after further actuation of the actuator 506.

CLAIMS What is claimed is: 1. A device comprising: a body; a hook coupled to the body, the hook configured to receive a collar; an arm coupled to the body, the collar being positioned between the arm and the hook; an actuator coupled to the hook; wherein when the collar is in an open configuration, the collar is positioned between and engaged by the hook and the arm, with the collar surrounding a peripheral nerve; and wherein, from the open configuration, the actuator is configured to pull the hook towards the body thereby forcing the collar to close around the peripheral nerve and force the collar into a closed configuration.

2. The device of claim 1, wherein the body comprises a first section and a second section separated from the first section; wherein the first section and the second section define the actuator; wherein the first section is coupled to the hook; wherein as the first section is pushed towards the second section, the hook is pulled towards the arm to close the collar around the peripheral nerve.

3. The device of claims 1 to 2, wherein the actuator is a first actuator and further comprising a second actuator; and wherein the second actuator is configured to insert a probe housing with a probe therein into the collar, when the collar is closed around the peripheral nerve.

4. The device of claims 1 to 3, wherein the body comprises a channel and the probe housing is positioned within the channel and further comprising a plunger positioned within the channel of the body and above the probe housing; and wherein the second actuator is configured to cause the plunger to advance within the channel and push the probe housing into a slot of the collar until one or more shanks of the probe insert into the peripheral nerve.

5. The device of claims 1 to 4, wherein the arm comprises a first finger and a second finger; ^{HB: 4933-6586-4273.1} 41 wherein in the open configuration each of the first finger and the second finger is configured to contact the collar.

6. The device of claims 1 to 5, wherein after the collar is in the closed configuration, the actuator is configured to force the arm further against the collar until the arm is released from the collar to remove the device from the collar.

7. The device of claims 1 to 6, wherein the arm comprises a first finger and a second finger, the first finger and the second finger being flexible; wherein the actuator forces the first finger and the second finger further against the collar until at least one of the first finger or the second finger deflects away from the collar thereby removing the arm from engaging the collar.

8. A device comprising: a body defining a channel therein; a hook coupled to the body, the hook configured to receive a collar; an arm coupled to the body, the collar being positioned between the arm and the hook; an actuator coupled to the body; a plunger coupled to the actuator and positioned within the channel of the body; and wherein when a probe housing is positioned within the channel of the body with the plunger positioned above the probe housing, the actuator is configured to advance to force the plunger to insert the probe housing into a slot of the collar.

9. The device of claim 8, wherein the arm comprises a first finger and a second finger; wherein the first finger and the second finger engage the collar to close the collar prior to or during insertion of the probe housing into the collar.

10. The device of claims 8 to 9, wherein the actuator is a plunger actuator and further comprising a hook actuator, the hook actuator being configured to pull the hook towards the arm thereby closing the collar around a peripheral nerve.

11. The device of claims 8 to 10, wherein the hook actuator moves independently of the plunger actuator. ^{HB: 4933-6586-4273.1} 42

12. The device of claims 8 to 11, wherein the hook actuator is coupled to the plunger actuator; and wherein as the hook actuator pulls the hook towards the arm thereby closing the collar around the peripheral nerve the plunger actuator advances the plunger to insert the probe housing into the slot of the collar.

13. The device of claims 8 to 12, wherein the slot of the collar is positioned between the first finger and the second finger when the first finger and the second finger engage the collar.

14. The device of claims 8 to13, wherein the body comprises a base and a shaft coupled to the base; and wherein the body comprises an extension coupled to the shaft at a free end of the shaft opposite the base; wherein the channel extends through the shaft and the extension; and wherein the extension is positioned between the first finger and the second finger.

15. The device of claims 8 to 14, wherein the hook comprises a hole; wherein the arm extends through the hole of the hook towards a free end of the hook; and wherein the arm is angled relative to the shaft.

16. The device of claims 8 to 15, wherein each of the first and second fingers comprises a recess that receives the collar when the first and second fingers engage the collar.

17. A method comprising: securing a collar to a device; manipulating the device to close the collar around a peripheral nerve of a subject; using the device to insert a probe housing including a probe positioned therein into a slot of the collar; and removing the device from the collar after the collar is closed around the peripheral nerve and the probe housing is positioned within the slot of the collar.

18. The method of claim 17, wherein manipulating the device to close the collar around a peripheral nerve of the subject comprises: ^{HB: 4933-6586-4273.1} 43 engaging an arm of the device with a first portion of the collar; engaging a hook of the device with a second portion of the collar, the second portion of the collar being pivotally coupled to the first portion of the collar, the collar being positioned between the hook and the arm; and pulling, using an actuator, the hook towards the arm to force the second portion of the collar to lock around the first portion of the collar.

19. The method of claims 17 to 18, wherein using the device to insert a probe housing including a probe positioned therein into a slot of the collar comprises: advancing, using an actuator, a plunger positioned within a channel of the device until the plunger contacts the probe housing positioned within the channel; and further advancing, using the actuator, the plunger until the probe housing is forced out of the channel and into the slot of the collar.

20. The method of claims 17 to 19, wherein removing the device from the collar comprises advancing an arm of the device further towards the collar until one or more fingers of the arm deflect away from the collar to disengage the arm from the collar. ^{HB: 4933-6586-4273.1} 44
