This disclosure describes embodiments of an anchor with a body configured to expand radially outwardly along its entire length. The anchor includes, but is not limited to, a cylindrical body having a longitudinal axis and an inner surface and an outer surface, the inner surface defining a central bore, the cylindrical body having a slot exposing the central bore, the slot having a helical path around the longitudinal axis, wherein the slot is configured to expand so that the cylindrical body changes from a first state to a second state in response to pressure on the inner surface, and wherein an outer diameter of cylindrical body in the second state is larger than the outer diameter of the cylindrical body in the first state.

A bone anchor including an outer sleeve defining slots and an inner sleeve including fins extendable radially outward through the slots to engage surrounding cancellous bone. The outer sleeve includes an outward extending flange disposed about an opening defined by the outer sleeve configured to receive a fastener. The flange can seat against cortical bone around an opening sized for the anchor. The anchor can be a suture anchor including the fastener that engages the inner sleeve when installed therein and pushes the fins outward to engage the cancellous bone as the fastener is installed, better securing the anchor to the bone, particularly where the bone is osteoporotic, weak, broken, diseased, and/or compromised. The outer sleeve can include projections between fins to prevent rotation as the fastener is installed. A related method of using the suture anchor is provided to anchor soft tissue with a suture to bone.

A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. A bone engaging fastener is coupled to bone. A second fastener is coupled to a suture construction. The second fastener is coupled to the first fastener. Soft tissue is coupled to the suture construction.

Systems and methods for providing fixation of soft tissue (for example, ligament) to bone by employing a novel multi-piece device. The novel multi-piece device is a ligament fixation system consisting of a larger collar that is initially impacted into a bone aperture, and a smaller plug/bullet-shaped part that is impacted into the larger collar. During ligament repair/reconstruction, the graft is inserted into a bone tunnel with sutures from the graft extending outside the tunnel. The sutures are passed through a collar of the multi-part device and the collar is then inserted into the bone tunnel. The graft suture strands may be tensioned. Subsequently, the smaller plug/bullet-shaped part is impacted into the collar thereby maintaining the tension on the graft sutures. The plug/bullet-shaped part is tightened after the desired tension on the suture is achieved.

This disclosure describes embodiments of an anchor with a body configured to expand radially outwardly along its entire length. The anchor includes, but is not limited to, an elongate body having a distal end, a proximal end, and a longitudinal axis extending therebetween, the elongate body having an outer surface and an inner surface, the inner surface defining a bore aligned with and extending along the longitudinal axis, the elongate body comprising a slot penetrating into the outer surface towards the longitudinal axis, the slot forming a path circumscribing the longitudinal axis.

A system for an anatomical joint includes a first fastener, a second fastener, a prosthetic ligament member, and a biasing member associated with at least one of the first and second fasteners. The first fastener is operable to be connected to a first bone portion. The second fastener is operable to be connected to a second bone portion. The prosthetic ligament member is flexible and is directly coupled to both the first and second fasteners to support the first bone portion and the second bone portion for relative movement. A portion of the prosthetic ligament member extends from the first fastener to the second fastener and has an adjustable length. The biasing member is operable to bias the prosthetic ligament member to thereby maintain tension in the prosthetic ligament member.

Various methods and devices are provided for a graft fixation device for fixing a graft member within a bone tunnel. In one embodiment, a graft fixation device is provided having a radially expandable sheath adapted to be disposed within a bone tunnel, and a sheath expander adapted to be received within the radially expandable sheath to expand the sheath and thereby anchor a graft between the sheath and the bone tunnel. In an exemplary embodiment, the graft fixation device is particularly useful to affix a graft within a femoral tunnel.

Devices and methods for securing a graft with respect to bone are provided. One exemplary embodiment of a surgical implant includes a flexible filament body and a suture filament or repair construct that extends through the filament body at multiple locations. The repair construct is formed into one or more coils, which can receive a graft. The flexible filament body can be configured to be actuated between unstressed and anchoring configurations, the latter of which sets a location of the suture filament, and associated graft, in a bone tunnel. More particularly, the flexible filament body can ball up, or become denser, to a size that cannot pass into the bone tunnel in which the suture filament holding the graft is disposed. The present disclosure also provides for feedback units to assist a surgeon in knowing a location of the implant. Further, other exemplary devices and methods are provided.

A method of treating a defective mitral valve includes percutaneously advancing a prosthetic device into a patient's heart. The prosthetic device includes an insert member and anchoring member. The prosthetic device is contained within a sheath along a distal end of a delivery catheter during advancement. The anchoring member is secured to a muscular wall of the left ventricle and the insert member self-expands between native leaflets of the mitral valve. The insert member preferably includes a biocompatible fabric outer layer, a passageway, and a valve member disposed within the passageway. After deployment, the native leaflets of the mitral valve form a tight seal against the fabric outer layer of the insert member for preventing regurgitation, while blood passes through the passageway of the insert member for allowing blood to pass from the left atrium to the left ventricle.

Tissue anchors and systems and methods for delivering and removing them are provided. In an exemplary embodiment, the tissue anchor may include an outer shell including a proximal end, a distal end, a passage extending therebetween, and a plurality of expandable arms; an expander including a proximal portion disposed within the passage and distal portion that extends distally from the outer shell distal, the expander movable proximally relative to the outer shell to a deployed position wherein the distal portion directs the plurality of arms outwardly to engage adjacent bone. A fork extends from the distal portion of the expander including a pair of tines spaced apart from one another and a concave distal surface extending between the tines. A suture loop extends from the distal portion of the expander for capturing a tissue structure.
