Abstract: A method of implanting a shoulder prosthesis in a scapula of a patient includes the step of placing a guide over a primary glenoid component previously implanted within the scapula of the patient. The method further includes the steps of removing the primary glenoid component from the scapula and preparing the scapula for implantation of a secondary glenoid component, wherein the removing and preparing steps occur simultaneously.

Abstract: 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 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.

Abstract: Improved prostheses comprising a tissue expander and a graft material are disclosed herein. Also disclosed are methods of making prostheses and methods of treatment using the prostheses.

Abstract: 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.

The present invention also provides methods of producing such constructs.

Abstract: An outer shell (1) for a joint socket implant, in particular for an acetabular implant, which comprises a convex outer face (3) and a concave inner face (4) for receiving an inner shell. The concave inner face (4) has at least partially a toothing system (7), in particular a circular circumferential region (6) thereof. Via the toothing system (7), an inhibition of the rotatability of the two shells, relative to one another, can be achieved upon insertion of the inner shell into the outer shell (1).

Abstract: A method for coating a sterile breast prosthesis packaged within a sterile blister package with a lubricious material while maintaining the sterility of the breast prosthesis is described.

Abstract: Methods of delivering and using an annuloplasty ring to reshape a valve annulus are disclosed. The methods include obtaining an annuloplasty ring having an elastic inner core member. The elastic inner core member can be defined by a multi-stranded braided cable. The inner core member has an unstressed closed or open ring shape and a first elastic modulus that enables the core member to be compressed from the unstressed ring shape into a stressed narrow shape and enables the annuloplasty ring to reshape a native heart valve annulus. The methods can include converting the annuloplasty ring from the unstressed ring shape into the stressed narrow shape, passing the annuloplasty ring through an access tube positioned with a distal tip adjacent a native valve annulus, and expelling the annuloplasty ring from the distal tip of the access tube so that it self-converts back towards the unstressed ring shape.

Abstract: Prosthetic heart valves described herein can be deployed using a transcatheter delivery system and technique to interface and anchor in cooperation with the anatomical structures of a native heart valve. Some embodiments of prosthetic mitral valves described herein include an anchor portion that couples the prosthetic mitral valve to the anatomy near the native mitral valve, and a valve portion that is mateable with the anchor portion.

Abstract: The present invention provides constructs including a tubular biodegradable polyglycolic acid scaffold, wherein the scaffold may be coated with extracellular matrix proteins and substantially acellular.

Abstract: A glenoid component includes a laterally facing bearing surface configured to engage a bearing surface of an element associated with a humerus, and a stem portion extending medially away from the bearing surface. The stem portion is configured such that when implanted in a scapula the stem portion includes three cross-sections parallel to a medial lateral plane. The middle cross-section has a length in the medial-lateral direction which is shorter than the lengths of the other two cross-sections in the medial lateral direction.

Abstract: A lung-volume-reduction elastic implant (500) is tubular and at least the proximal end of the implant has an opening. The implant (500) comprises an elastic deforming part (51) and a flexible guiding part (53) connected to the distal end of the elastic deforming part (51). The elastic deforming part (51) has a shape memory property. The elastic deforming part (51) is provided in the lengthwise direction thereof with several slots (514) at intervals, wherein each slot (514) communicates with the tubular cavity of the elastic deforming part (51). Under the same externally applied force, the flexible guiding part (53) deforms more easily than the elastic deforming part (51). An implant delivering instrument (600) comprises an implant (500) and a matching delivering means (700). The delivering means (700) comprises a core wire (71) and a hollow pushing member (73). The implant (500) is detachably connected to the distal end of the pushing member (73) by means of the proximal end of the implant.
