No. 11/923,526 (the '526 application), entitled Methods and Systems for Material Fixation, filed on Oct. 24, 2007, and herein expressly incorporated by reference in its entirety.
  • Current ACL repairs may be difficult to perform, require more steps, additional procedure time, extra drilling, external jigs or fixtures or multiple assistants. The device is an easy to use positioning and installation tool for a femoral implant of the type disclosed in the '526 application. The device is inserted through a single, simple drill hole and positioned into place. The device controls the degree to which the implant is deployed and prevents accidental disengagement from the implant before deployment has completed. The device also guides the components of the implant involved in active tendon compression at the aperture of the femoral tunnel. The implant is deployed simply by rotating a knob, thereby creating a femoral anchor point of high stiffness and fixation strength. When deployment has completed, the inserter is disengaged from the affixed implant by simply pulling a release mechanism.
  • The use of the device is straightforward, eliminating potential for confusion that may arise when using other femoral fixation technologies. No additional accessories or steps are required. The only required step in preparation for fixation is to locate and drill a single tunnel within the femur.

Preferably, the deployment control comprises a rotatable knob and the safety mechanism comprises a safety pin which is removable to permit rotation of the rotatable deployment knob.
  • The inventive insertion device further comprises a mechanism for limiting rotation of the deployment knob to only one direction, wherein because the deployment knob may only be rotated in one direction, the deployment knob may be advanced distally, but not retracted proximally. The implant retention mechanism comprises a ball detent mechanism. The ball detent mechanism comprises a detent ball, a detent ball retainer, and a ball detent rod. An insertion shaft spring is disposed on the ball detent rod.
  • The fixation implant comprises an implant screw for deploying the fixation implant. The implant screw comprises a head having a hole for engaging the detent ball. The implant release control comprises a knob which is movable proximally to disengage the implant retention mechanism from a fixation implant engaged therewith. A hex tube is disposed at the distal end of the insertion shaft. The implant retention mechanism is disposed on the hex tube and the hex tube has a recess for receiving a portion of the fixation implant.
  • The implant screw further comprises internal left-hand threads disposed on an interior surface in the head, defining the hole, so that the implant screw may be disengaged from the fixation implant. A shaft having external threads extends distally from the implant screw head.
  • In another aspect of the invention, there is provided a fixation implant for securing soft tissue to bone or bone to bone, wherein the fixation implant comprises an implant screw for deploying the fixation implant. The implant screw comprises a head having a hole for engaging a detent ball forming part of an implant retention mechanism on an insertion tool. The implant screw further comprises internal left-hand threads disposed on an interior surface in the head, defining said hole, so that the implant screw may be disengaged from the fixation implant, and a shaft having external threads, extending distally from the head.

    •  DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The device 10 of the present invention is an inserter, used for positioning and deployment of a fixation implant like that described in the '526 application. The user interface features of the inserter 10, depicted in FIG. 1, are a handle 12, a safety pin 14, an insertion shaft 16, a deployment knob 18, a release knob 20, and suture cleats 22.
  • At the end of the insertion device 10, a sutured soft tissue graft (not shown) is loaded onto the implant (not shown), and the free suture strands (not shown) are secured to the suture cleats 22 to allow for suture management and easy insertion of the graft complex. The suture cleats 22 are designed to be easily and quickly wrapped with suture. After the suture has been attached to the cleats, the inserter is placed inside a femoral tunnel 24 in the femur 26 of a patient (FIG. 3). When it has reached the desired deployment location, the inserter and implant are deployed. Deployment is performed by removing the safety pin 14 and rotating the deployment knob 18 in a clockwise fashion until the deployment knob 18 comes into contact with the inserter handle 12, or until it can no longer be turned. An implant (not shown) is attached to the tip of the insertion shaft 16 by means of a ball detent mechanism (FIG. 2), comprising a detent ball 28, a detent ball retainer 30, and a ball detent rod 32, on which is disposed an insertion shaft spring 34. The ball detent mechanism engages with a hole 36 (FIG. 4A, 4B, 4C) in an implant screw 38. Deployment motion of the inserter 10 is ratcheted and is limited to the clockwise direction to prevent accidental undeployment. By rotating the deployment knob 18, the diamond wedge of the implant expands the implant arms outward, which provide fixation by engaging against the wall of the femoral tunnel 24. To disengage the implant from the inserter 10, the implant release knob 20 is pulled, releasing the detent mechanism. The insertion device can then be removed from the soft tissue graft implant site after any suture has been detached from the suture cleats 22.
  • The device may come preloaded with the fixation implant attached to the inserter tip 40 (FIG. 3). FIGS. 4A-4C show the implant screw 38, held to a hex tube 42 of the inserter 10 by means of the aforementioned ball detent mechanism and hole 36 in the implant screw. The head 44 of the implant screw 38 has internal left hand threads 46 (FIG. 4C) in order to remove the screw if a revision of the implant should be necessary. To remove the screw, a left-hand threaded removal tool is screwed into the hex head 44 of the screw, securing the screw to the removal tool. The tool is then rotated in a counterclockwise direction to unscrew and disengage the screw from the implant.
  • Now referring more particularly to FIG. 2, a threaded ratchet shaft 48 has a multitude of cuts running parallel to its length, designed to engage a pawl 50, limiting its rotation to the clockwise direction. The pawl 50 is fitted over a pawl axle 52 which rests inside a mated cavity in a handle bottom 54. As the threaded ratchet shaft 48 rotates clockwise, the pawl 50 is deflected downwards towards the handle bottom 54. When the pawl 50 comes into contact with one of the cuts in the threaded ratchet shaft 48, it is returned to the engaging antirotation position by a torsion spring 56. If motion is attempted in the counterclockwise direction, the flat face of the cutout in the threaded ratchet shaft 48 engages the flat face of the pawl 50, preventing antirotation. A leaf spring may be substituted for the pawl 50 and torsion spring 56 if it is positioned such that it engages the flat face of the threaded ratchet shaft 48.
  • The deployment knob 18 may be attached to the threaded ratchet shaft 48 by means of an alignment pin 58. As the deployment knob 18 rotates the threaded ratchet shaft 48 in a clockwise direction, it is translated linearly forward by a stationary translation nut 60. The translation nut 60 is fitted inside a cavity in the handle bottom 54 and the handle top 62. The deployment tube 64, which engages with and turns the implant screw, is affixed to the threaded ratchet shaft 48. The threaded ratchet shaft 48 and implant screw are threaded so that the turn to travel ratio are 1:1 between the two components. Therefore, as the threaded ratchet shaft 48 and deployment tube 64 rotate, the per-turn linear travel of the threaded ratchet shaft 48 is equal to the linear travel of the implant screw within the implant body.
  • The inserter tip 40 interfaces with the compression pads on the femoral implant to prevent implant rotation and assists in aligning and guiding the compression pads as they separate. The insertion shaft 16 is preferably a hollow cylindrical collar that is allowed to freely slide over the deployment tube 64. An anti-rotation washer 66 has a machined groove that aligns to a longitudinal rib in the handle top 62. The anti-rotation washer has a positive spring bias created by the insertion shaft spring 34. The insertion shaft spring 34 is constrained by a rib within the handle top 62. As the assembly of the inserter tip 40, insertion shaft 16, and anti-rotation washer 66 moves distally during the course of implant deployment, the insertion shaft spring 34 compresses, providing a reaction force that ensures the inserter tip 40 remains engaged with the implant.
  • The deployment tube 64 contains a hollow cylindrical center portion that allows the ball detent rod 32 to slide freely within. The ball detent rod 32 also fits within the detent ball retainer 30 that is fixed inside the tip of the deployment tube 64. The purpose of the detent ball retainer 30 is to retain the detent ball 28 within the deployment tube 64 and to constrain its motion inwards and outwards from the engaging hex face of the deployment tube 64. The inside engaging hex face of the deployment tube 64 is drilled in such a manner that the detent ball 28 is prevented from falling out of the assembly yet is still allowed to protrude enough for significant engagement with the implant screw.
  • The detent ball 28 is sandwiched above the detent ball retainer 30 and below the engaging hex face of the deployment tube 64. As the ball detent rod 32 slides into the detent ball retainer 30, it pushes the detent ball 28 from the engaging hex face of the deployment tube 64. In this state, the detent ball 28 protrudes a distance out of the engaging hex face of the deployment tube 64 and is prevented from retracting back into the engaging hex face by the support of the ball detent rod 32 underneath.
  • The ball detent rod 32 is connected to a spring shaft 68 which is equipped with an engagement spring 70 that translates a positive engagement force to the ball detent rod 32. The engagement spring 70 is confined within the deployment knob 18 and a deployment knob cover 72 which it is compressed by when the spring shaft 68 is retracted.
  • It is to be understood that the figures of the bone and anchors seen above are purely illustrative in nature, and are not intended to limit the application of the inventive embodiments to any particular physiological application or purpose. The invention is applicable to many different types of procedures involving, in particular, the attachment of connective or soft tissue to bone.

Claims (21)

1.-19. (canceled)
20. A method of deploying a fixation implant in a tunnel formed in a bone, comprising:
positioning a fixation implant retained on a distal end of an insertion tool in a tunnel formed in a bone, the fixation implant, comprising:
an implant body having a distal end, a proximal end, and a longitudinal axis;
a first arm on the implant body, the first arm located at the distal end of the implant body and being outwardly deployable relative to the longitudinal axis of the implant body for engaging a wall in the tunnel for implanting the implant body in the tunnel; and
a first compression pad on the implant body, the first compression pad located at the proximal end of the implant body and being outwardly deployable relative to the longitudinal axis of the implant body for moving soft tissue that is situated between the first compression pad and the wall in the tunnel away from the longitudinal axis of the implant body for compressing the soft tissue against bone in the tunnel; and
rotating a knob of the insertion tool relative to a handle portion of the insertion tool, wherein said rotating causes a rotatable element that is linked to the knob through the insertion tool to rotate relative to the longitudinal axis of the implant body, the rotatable element extending longitudinally through the implant body to engage a wedge disposed in the distal end of the implant body such that rotating the rotatable element: (a) moves the wedge in a proximal direction inside the implant body so that the wedge contacts the first arm and forces the first arm to deploy outwardly relative to the longitudinal axis of the implant body; and (b) moves a proximal deployment element that is located proximally of the wedge inside the implant body in a distal direction so that the proximal deployment element contacts the first compression pad and forces the first compression pad to deploy outwardly relative to the longitudinal axis of the implant body.
21. The implanting system of claim 20 further comprising disengaging a safety pin from the handle portion prior to said rotating, wherein the safety pin, prior to said disengaging, prevents said rotating.
22. The implanting system of claim 20, wherein the insertion tool allows for rotation of the rotatable element in only one direction relative to the longitudinal axis of the implant body when the rotatable element is extending longitudinally through the implant body.
23. The implanting system of claim 20 further comprising coupling a soft tissue graft to the fixation implant.
24. The implanting system of claim 23 further comprising securing a suture attached to the soft tissue graft to a suture cleat on the insertion tool.
25. The implanting system of claim 20, wherein said rotating is performed until the knob contacts the handle portion of the insertion tool.
26. The implanting system of claim 20, wherein the fixation implant further comprises a second arm on the implant body, the second arm being located at the distal end of the implant body and being outwardly deployable relative to the longitudinal axis of the implant body for engaging the wall in the tunnel for implanting the implant body in the tunnel.
27. The implanting system of claim 26, wherein the second arm is separated from the first arm on the implant body.
28. The implanting system of claim 20, wherein the fixation implant further comprises a second compression pad on the implant body, the second compression pad being located at the proximal end of the implant body and being outwardly deployable relative to the longitudinal axis of the implant body for moving soft tissue that is situated between the first compression pad and the wall in the tunnel away from the longitudinal axis of the implant body for compressing the soft tissue against bone in the tunnel.
29. The implanting system of claim 28, wherein the second compression pad is separated from the first compression pad on the implant body.
30. The implanting system of claim 20, wherein the implant body has a longitudinal passage extending from the proximal end to the distal end of the implant body, the wedge and the proximal deployment element positioned in the longitudinal passage.
31. The implanting system of claim 20, wherein the implant body is sized for deployment through a 5-8 mm cannula.
32. A method of deploying a fixation implant in a tunnel formed in a bone, comprising:
positioning a fixation implant retained on a distal end of an insertion tool in a tunnel formed in a bone, the fixation implant, comprising:
an implant body having a distal end, a proximal end, and a longitudinal axis;
a first arm on the implant body, the first arm located at the distal end of the implant body and being outwardly deployable relative to the longitudinal axis of the implant body for engaging a wall in the tunnel for implanting the implant body in the tunnel; and
a first compression pad on the implant body, the first compression pad located at the proximal end of the implant body and being outwardly deployable relative to the longitudinal axis of the implant body for moving soft tissue that is situated between the first compression pad and the wall in the tunnel away from the longitudinal axis of the implant body for compressing the soft tissue against bone in the tunnel;
actuating a deployment system that extends longitudinally through the implant body, wherein said actuating: (a) moves a distal deployment element of the deployment system in a proximal direction inside the implant body so that the distal deployment element contacts the first arm and forces the first arm to deploy outwardly relative to the longitudinal axis of the implant body; and (b) moves a proximal deployment element of the deployment system in a distal direction inside the implant body so that the proximal deployment element contacts the first compression pad and forces the first compression pad to deploy outwardly relative to the longitudinal axis of the implant body; and
disengaging a safety pin from a handle portion of the insertion tool prior to said actuating, wherein the safety pin, prior to said disengaging, prevents said actuating.
33. The implanting system of claim 32, wherein the distal deployment element comprises a wedge.
34. The implanting system of claim 32, wherein the implant body is sized for deployment through a 5-8 mm cannula.
