Methods and devices are provided for anchoring a ligament or tendon to bone. In one embodiment, a biceps tenodesis system is provided and includes a sheath inserter tool, an expandable sheath configured to couple to the sheath inserter tool, an expander inserter tool, and an expander configured to couple to the expander inserter tool. The sheath inserter tool is configured to advance the expandable sheath, with a tendon disposed therearound, into a bone hole, and the expander inserter tool is configured to advance the expander through an outer shaft of the sheath inserter tool and to drive the expander into the sheath. The expander is configured to be received within a lumen extending at least partially through the expandable sheath to thereby expand the sheath. In this way, the system delivers the tendon or ligament into the bone hole and locks the sheath and tendon within the bone hole.

A knotless suture anchor may include an anchor body with a proximal end, a distal end, an interior longitudinal passageway, a proximal opening communicating with the longitudinal passageway nearer the proximal end, and a distal opening communicating with the longitudinal passageway nearer the distal end. A first suture portion extends within the longitudinal passageway between the proximal opening and the distal opening, a second suture portion is contiguous to the first portion and extending out of the anchor body, a third suture portion is contiguous to the second portion and extends within the longitudinal passageway proximally to distally, and a fourth suture portion is contiguous to the third portion, extending along the exterior surface distally to proximally. A proximal member may be joined to the anchor body by a frangible connection and may have a proximal member axial passage containing an interference member coaxially aligned with the longitudinal passageway.

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 hone, 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 hone 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.

Systems and tools are provided for anchoring a ligament or tendon to bone. In one embodiment, a sheath is provided having a first sidewall with proximal and distal ends and a second sidewall with proximal and distal ends. The distal ends of the first and second sidewalls can be coupled to one another by a hinge pin such that the first and second sidewalls pivot relative to one another about the hinge pin. A sheath inserter tool is also provided and it can be configured to couple to the sheath and to advance the expandable sheath, with a tendon disposed therearound, into a bone hole. An expander is also provided for expanding the sheath. In this way, a tendon or ligament is delivered into the bone hole and the sheath and tendon are locked within the bone hole.

Systems and methods for fixating a graft in a bone tunnel are provided. In general, the system includes a tissue fixation device having a delivery configuration and a deployed configuration, at least one graft retention loop coupled to the tissue fixation device, and a drill pin having a sidewall surrounding a cavity at a proximal end of the pin and at least one longitudinally oriented opening in the sidewall in communication with the cavity, the cavity being configured to fully seat the tissue fixation device. The drill pin is configured to substantially contain therein the tissue fixation device when in the delivery configuration and to enable deployment of the tissue fixation device through the opening. Drill pins configured to contain a tissue fixation device are also provided.

Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A tissue anchoring device is described that comprises an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and inside surfaces of a bone tunnel to secure the tissue within the tunnel. An anchoring device is described that comprises an anchor body having compressible tabs with teeth, and a spreader that forces the compressible tabs into an expanded state when inserted into anchor body, facilitating engagement between bone and the teeth of the compressible tabs. Methods are described that enable use of the bone anchoring device to secure a tissue graft into the tibial and femoral bones during anterior cruciate ligament (ACL) reconstruction.

A bone anchor configured for use in anchoring an implanting portion to an anchor point. A bone anchor can be of particular use in anchoring soft tissue to a bone. A bone anchor can have a wire loop and a suture. The wire loop of the bone anchor can be configured to capture a suture and to pull a portion of the suture through a hole in the anchor body aiding in anchoring an item, such as tissue to a bone. Methods of using the bone anchor with a suture and a wire loop to attach an item are disclosed.

Methods and devices are provided for anchoring a ligament or tendon to bone. In particular, various delivery tools, including a variety of sheath inserter tools, are provided. The tools can be used to position a tendon within a prepared bone hole, and to deliver a sheath into the bone hole.

A graft ligament anchor includes a tubular body having a bore therethrough and proximal and distal ends. A flange is attached to the tubular body at the proximal end thereof and extends radially outwardly beyond the tubular body. A deformable wall is disposed in the tubular body bore and defines, at least in part, a chamber for retaining the graft ligament therein. An expansion device is configured for insertion into the tubular body axially of the tubular body, and for impinging upon the deformable wall to press the deformable wall, and hence the graft ligament received in the chamber, toward a wall of the bore, whereby to fix the graft ligament in the tubular body.
