Definitions
- This invention generally relates handles having rotational detachment mechanisms for use with medical device deployment systems that deploy implantable medical devices at target locations within a human body vessel, and methods of using the same.
- catheter delivery systems for positioning and deploying therapeutic devices, such as dilation balloons, stents and embolic coils, in the vasculature of the human body has become a standard procedure for treating endovascular diseases. It has been found that such devices are particularly useful in treating areas where traditional operational procedures are impossible or pose a great risk to the patient, for example in the treatment of aneurysms in cranial blood vessels. Due to the delicate tissue surrounding cranial blood vessels, especially for example brain tissue, it is very difficult and often risky to perform surgical procedures to treat defects of the cranial blood vessels. Advancements in catheter deployment systems have provided an alternative treatment in such cases. Some of the advantages of catheter delivery systems are that they provide methods for treating blood vessels by an approach that has been found to reduce the risk of trauma to the surrounding tissue, and they also allow for treatment of blood vessels that in the past would have been considered inoperable.
- these procedures involve inserting the distal end of a delivery catheter into the vasculature of a patient and guiding it through the vasculature to a predetermined delivery site.
- An implantable medical device such as an embolic coil or vascular stent, is attached to the end of a delivery member which pushes the medical device through the catheter and out of the distal end of the catheter into the delivery site.
- Some of the delivery systems associated with these procedures utilize a control wire, sometimes referred to as a pull wire, to activate the release and deployment of the medical device.
- a control wire sometimes referred to as a pull wire

- the carrier member 14 is a hypotube that may be comprised of a biocompatible material, such as stainless steel.
- the hypotube typically will have a diameter of between about 0.010 inch (0.254 mm) and about 0.015 inch (0.381 mm), a preferred tube having a diameter of approximately 0.013 inch (0.330 mm).
- Such a carrier member 14 is suitable for delivering and deploying implantable medical devices, such as embolic coils, vascular stents or the like, to target locations, typically aneurysms, within the neurovasculature, but differently sized carrier members comprised of other materials may be useful for different applications .
- implantable medical devices such as embolic coils, vascular stents or the like
- An engagement member 20 is associated with the distal end portion 16 of the carrier member 14.
- the engagement member 20 can comprise a distal end length of an elongated wire loosely bent in half to define an opening 22 (Fig. 2) .
- the proximal end or ends 24 of the engagement member 20 can be fixedly connected to the carrier member 14 at a location proximal to the distal end portion 16.
- the engagement member 20 can comprise a flat ribbon defining the opening 22 at a distal portion thereof.
- the engagement member 20 typically is deformable to the up-turned condition illustrated in Figs. 1 and 2.
- the engagement member 20 can be elastically deformable to the up-turned condition of Figs. 1 and 2, such that it will return to a substantially flat condition, illustrated in Fig. 3 when not otherwise constrained, as will be explained in more detail below.
- the engagement member up-turned condition is generally straightened by contact with another component that "unbends" this member.
- the engagement member 20 may be comprised of any of a number of materials, including nitinol and stainless steel. The function of the engagement member 20 will be described in greater detail herein.
- the deployment system 10 further includes a control member 26, such as a control wire or pullwire, received within the lumen 28 of the carrier member 14 and movable with respect to the engagement member 20.
- the control member 26 stretches beyond the proximal end portion 18 of the carrier member 14 and is operatively connected to the handle 12.
- the control member 26 may be a wire comprised of any of a number of materials, including nitinol. The function of the control member 26 will be described in greater detail herein.
- an implantable medical device 30 such as the illustrated embolic coil, is releasably attached to the distal end portion 16 of the carrier member 14 by the engagement member 20,
- an aperture- containing proximal end portion 32 of the implantable medical device 30 is placed adjacent to opening 22 of the engagement member 20, which is then deformed to the up-turned condition of Figs, 1 and 2.
- the opening 22 may be moved to the up-turned condition prior to placement of the implantable medical device 30. In the up-turned condition, at least a portion of the opening 22 passes through the aperture of the proximal end portion 32.
- the engagement member 20 can be elastically deformable to the up-turned condition of Figs. 1 and 2 so it will tend to return to a substantially flat condition as illustrated in Fig. 3,
- the distal end portion 33 of the control member 26 is moved axially through the opening 22 to the position shown in Figs. 1 and 2,
- the control member 26 holds the engagement member 20 in the upturned condition, and the engagement member 20 releasably secures the proximal end portion 32 of the implantable medical device 30 to the distal end portion 16 of the carrier member 14.
- the handle 12 can include a handle body 34 having a proximal end portion 36 and a distal end portion 38 wherein the distal end portion 38 is connected to the proximal end portion 18 of the carrier member 14.
- the handle body 34 can be comprised of a proximal wall 40 and a circumferential wall 42 that define a cavity 44.
- the cavity 44 communicates with the lumen 28 of the carrier member 14 and accepts a proximal end portion 46 of the control member 26.
- the circumferential wall 42 can be a continuous arcuate wall which forms a handle body having a generally circular cross-section, such as a generally cylindrically shaped handle body, or the circumferential wall could be comprises of a series of panels or sub-walls which form a handle having a rectangular cross-section.
- a rotatable member 48 such as the illustrated generally cylindrical rotational sleeve, is located within a portion of the cavity 44 that is configured to house the rotatable member and allow the rotatable member to rotate relative to the handle body 34, the carrier member 14 and the control member 26.
- the rotatable member 48 can rotate in the direction of "A" or the direction of "B" (Fig. 1), as desired or as required by the application of use.
- the rotatable member 48 includes an internal threaded surface 50 (perhaps best shown in Fig. 3) which defines a lumen 52 that accepts the proximal end portion 46 of the control member 26.
- the proximal end portion 46 of the control member 26 is threaded to correspond to and threadably engage the internal threaded surface 50 of the rotatable member 48.
- the threading on the proximal end portion 46 of the control member 12 can be any suitable threading, such as a grooved surface or a twisted shape of the proximal end 46 of the control member 26.
- the threaded engagement between the internal surface 50 of the rotatable member 48 and the proximal end portion 46 of the control member 26 causes the control member to move in a proximal or distal direction depending on the direction of rotational movement of the rotatable member 48.
- the cavity 44 of the handle can include a through port 54 at a location that is proximal the rotatable member. The through port 54 accepts the proximal end portion 46 of the control member 26 as the control member is moved proximally out of the proximal end of the rotatable member 48.
- the control member 26 can include stops 56a, 56b that contact the rotatable member 48 and prevent further movement of the control member 26 in a particular direction. For example, as illustrated in Fig. 3, when the stop 56b contacts the rotatable member 48, the stop 56b prevents any further movement of the control member 26 in the proximal direction.
- the locations of the stops 56a and 56b can be varied along the control member 26 and can be placed at preselected locations prior to use so that the control member only moves a pre-determined distance in the axial direction.
- the handle body 34 and rotatable member 48 are preferably configured so that the rotatable member 48 can be rotated by hand, but both may also be configured to be rotated by instrument.
- the circumferential wall 42 of the handle body 34 can include an aperture or window 58 that extends through the wall 42 to allow access to the rotatable member 48 so that the rotatable member can be rotated.
- the rotatable member 48 preferably includes an outer surface 60 that is textured or knarled to provide a gripping surface that may be gripped by a finger of a user to rotate the rotatable member 48.
- the medical device 30 can be attached to the deployment system 10 as described above and as illustrated in Figs. 1 and 2.
- a user can access the rotatable member 48 through window 58 to cause rotation of the rotatable member relative to the control member 26.
- the threaded engagement between the internal surface 50 and the proximal end portion 46 of the control member 26 causes the control member to move proximally relative to the engagement member 20.
- this proximal movement proceeds so that the distal end portion 33 of the control member 26 moves out of the opening 22 of the engagement member 20, Once the distal end portion 33 of the control member 26 is moved out of opening 22 of the engagement member 20, the engagement member is free to allow release of the medical device 30.
- Fig. 3 shows the engagement member 20 returned to its flat configuration, thereby releasing the medical device 30. This return can be due to a bias in the engagement member 20 or by a straightening-type of engagement with the medical device 30 as it separates from the detachment device.
- a tubular catheter (not shown) is fed into a body vessel until a distal end thereof is adjacent to a target location. Thereafter, the deployment system 10 and associated implantable medical device 30 are advanced through the catheter, using procedures and techniques known in the art, until the device 30 is itself generally adjacent to the target location. Alternatively, the deployment system 10 and associated device 30 may be pre-loaded in the catheter, with the combination being fed through a body vessel to a target location. Other methods of positioning the implantable medical device 30 generally adjacent to a target location may also be practiced without departing from the scope of the present invention, [0035] To more accurately position the engaged device 30, radiopaque markers (not illustrated) may be attached to the carrier member 14 or the device 30 itself.
- the rotatable member 48 When the engaged device 30 has been properly positioned and oriented, the rotatable member 48 is rotated, preferably by hand through window 58 in wall 42 of the handle body, relative to the control member 26. Referring to Fig. 3, as the rotatable member 48 is rotated, the threaded engagement between the internal surface 50 of the rotatable member 48 and the proximal end portion 46 of the control member 26 causes the control member 26 to move in a proximal direction and out of engagement with the engagement member 20- The engagement member 20 is allowed to return to its original substantially flat condition or is moved to a release condition by engagement with another component of the system, thereby disengaging the aperture-containing end portion 32 of the implantable medical device 30 and deploying the medical device 30.
- the control member 26 may be provided with a radiopaque portion to provide visual feedback to indicate when the device 30 has been released.
- the deployment system 10 may be removed from the patient alone or in conjunction with the catheter.
- Figs. 5 and 6 illustrate an alternative embodiment of a handle in accordance with present invention.
- the deployment system 10a includes a handle 12a which includes a handle body 62 and a rotatable member 64.
- the rotatable member 64 is rotatably coupled to the proximal end portion 18a of the carrier member 14a so that the rotatable member is rotatable relative to the carrier member 14a and the handle body 62, as will be explained in more detail herein.
- the rotatable member 64 can be rotatably coupled to the proximal end portion 18a of the carrier member 14a by any suitable rotatable coupling configuration; for example, one suitable rotational coupling is a rotatable coupling similar to the rotatable couplings used in rotatable hemostatic valves, which are well known in the art.
- the rotatable member 64 includes an internal threaded surface 66 which defines a lumen 68.
- the proximal end portion 18a of the carrier member 14a is located within the lumen 68 r and a rim 70 extending radially form the proximal end portion 18a of the carrier member 14a is located within a groove 72 of the rotatable member 64 to mechanically and rotatably connect the rotatable member 64 to the carrier member 14a.
- the handle body 62 includes a threaded portion 74 and ' a gripping portion 76 extending from the threaded portion 74.
- the threaded portion 74 is located within the lumen 68 of the rotatable member 64 and includes a threaded surface 78 corresponding to and engaging the threaded internal surface 66 of the rotatable member 64.
- the threaded engagement between the threaded portion 74 of the handle body 62 and the internal threaded surface 66 of the rotatable member 64 can be any suitable threaded engagement.
- the threaded surface 78 of the threaded portion 74 includes a grooved thread 80
- the threaded surface 66 of the rotatable member 64 includes at least one projection 82 that follows along the groove 80 as the hand body 62 and rotatable member 64 are rotated relative to one another.
- the threaded engagement between the handle body 62 and the rotatable member 64 causes the handle body 62 to move axially in a proximal or distal direction depending on the direction of relative rotation and the desired use.
- the proximal end 46a of the control member 26a is operatively connected to the handle body 62 so that the control member 26a moves proximally and distally with the handle body 62.
- the handle body 62 and rotatable member 64 can be rotated relative to one another by a variety of methods.
- the gripping portion 76 of the handle body 62 can be grasped to hold the handle body 62 in a rotationally stationary position, and the rotatable member 64 can be rotated relative to the handle body 62.
- the rotatable member 6A can be held in a rotationally stationary position, and the handle body 62 can be rotated relative to the rotatable member 64.
- the rotatable member 64 could be rotated in one direction and the handle body 62 could be rotated in the other direction.
