A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression. Graft strength has been found to be greater than 1,000 N (Newtons), which is desirable for ACL reconstruction systems.

A method of anchoring soft tissue to a suitable bone site, using a soft suture anchor, includes steps of disposing the soft suture anchor on a shaft of an inserter, and securing a proximal end of a tensioning suture limb, extending proximally from the soft suture anchor, to structure in a handle of the inserter, so that it is maintained in place at a first level of holding tension (T_(hold)). The inserter shaft is inserted into a bone hole at a desired procedural site, so that the soft suture anchor is positioned at a location where it is to be anchored. A further step involves actuating a control mechanism in the inserter handle to move the structure proximally to apply a second level of deployment tension (T_(load)) to the tensioning suture limb.

A device for repairing a tear in a portion of tissue comprises a proximal actuator portion, a transfer needle extending distally from the proximal actuator portion and a catch needle extending distally from the proximal actuator portion. A suture needle is disposed in the transfer needle, and is extendable from the transfer needle toward the catch needle and retractable from the catch needle toward the transfer needle. An extendable catch plunger is disposed in the catch needle for capturing suture therein when it is transferred from the transfer needle. A retractable insertion sheath is provided for covering the transfer needle and the catch needle when the device is inserted into a procedural site. A depth limiting apparatus limits the depth of insertion of the needle into the procedural site.

A method of anchoring soft tissue to a suitable bone site, using a soft suture anchor, includes steps of disposing the soft suture anchor on a shaft of an inserter, and securing a proximal end of a tensioning suture limb, extending proximally from the soft suture anchor, to structure in a handle of the inserter, so that it is maintained in place at a first level of holding tension (Thold). The inserter shaft is inserted into a bone hole at a desired procedural site, so that the soft suture anchor is positioned at a location where it is to be anchored. A further step involves actuating a control mechanism in the inserter handle to move the structure proximally to apply a second level of deployment tension (Tload) to the tensioning suture limb.

A system and method for making an orthopedic repair by fixing a soft tissue graft to bone, utilizes an implant including a body wedge having first and second outwardly expandable wedge portions, a wing portion having outwardly expandable wings, and a deployment member which is movable distally into the implant to deploy the wedge portions and the wings into an expanded deployed orientation.

A wicking component is integrated into an arthroscopically deployable bone anchor, and is intended to improve soft tissue-to-bone repair. Once deployed, the fibrous wick component extends from within the bone tunnel, out of the hole, and to the bone-tendon interface on the bone surface. The tissue is approximated against the bone, sandwiching the wick material between the bone and tissue. The wick component is ideally a polymeric fibrous or tissue-based scaffold that provides a pathway for cells (autologous bone marrow constituents and blood) to travel from within the bone to the soft tissue-bone interface, accelerating and promoting the healing response. The system provides a biomimetic structure that stimulates the extracellular matrix to encourage cell attachment and potentially improve the healing response. The wick component does not need to be integrated into a suture anchor and installed when the suture anchor is deployed. For example, the wick component could be placed above or near a traditional suture anchor after it has been deployed.

An anchoring system for securing tissue to bone includes an implant having a body through which a suture eyelet extends transversely, a suture recess extending along a portion of a length of the body, having a predetermined depth below an outer surface of the body, and a suture pinch ramp disposed at a proximal end of the suture recess. The suture pinch ramp has a depth approximately equal to the predetermined depth at a distal end thereof and sloping outwardly in a proximal direction so that a depth of a proximal end of the suture pinch ramp approaches zero. An insertion member includes an insertion tube and a handle which is engageable with the anchor body to deploy the anchor in a selected bone site.

The present invention provides a novel split barbed fixation device for tenodesis, soft tissue reattachment of tendons and ligaments to bones. The insertion device is adapted for an entirely arthroscopic approach while achieving fixation strength with ultimate pullout resistance comparable to interference screws. The device includes an integrated tendon grasper that provides for easy manipulation of the tendon arthroscopically while eliminating the need for external whip stitching of the tendon, thereby reducing preparation time. The device further includes elements that prevent the fixation implant from being destabilized or rotating during deployment and manipulation, including: a depth limiting sheath, a first implant retainer, a first implant retaining step, a tendon grasping needle tube, and an implant keyway for mating the implant to the tube. The implant itself comprises two separate portions mating along a diagonal and having barbed surface features in opposite directions, only one of which contacts the tendon.

The present invention provides a method and device for restoring individual patient joint kinematics using minimally invasive surgical procedures. The instrumentation of the invention sculpts the articular surface of a first bone that normally articulates in a predetermined manner with a second bone. The instrumentation includes a bone sculpting tool and a mount for attaching the tool to the second bone. The implant system is comprised of implants that provide intraoperative surgical options for articular constraint and facilitate proper alignment and orientation of the joint to restore kinematics as defined by the individual patient anatomy.

A method for securing suture to bone comprises drilling a hole in a desired portion of bone at a desired procedural site, passing a strand of suture through a portion of soft tissue to be approximated to the portion of bone, and extending the free suture ends proximally from the soft tissue. The suture is loaded into an anchor implant. Using an inserter, on a distal end of which is attached the anchor implant, the anchor implant is manipulated into the bone hole. The suture is then tensioned to a desired level by pulling on the free suture ends, after the anchor implant is positioned in the bone hole. The free suture ends are wrapped about a suture cleat on an inserter handle once the desired tension level is achieved. A proximal anchor component is moved distally to engage with a distal anchor component to lock the anchor in place within the bone hole, and to lock the suture in place within the anchor. Then, the inserter is removed from the procedural site.
