Abstract:
A bi-directional suture passing instrument configured to approach soft tissues perpendicularly, enables safer and more efficient surgical repairs and minimally invasive techniques to be employed, useful in areas such as annulus repair, meniscal repair, shoulder arthroscopy, hernia repair, laproscopic repair, and wound closure.
Abstract:
A flexible chain implant for insertion into an interior volume of a vertebral body. The implant may be implanted in an insertion position for sliding through a cannula and is flexible for packing into the interior volume in an implanted configuration. The implant randomly separates in the implanted configuration. The implant includes a top member and a bottom member, wherein the top and bottom members are coupled to one another at a coupled portion. The top and bottom members preferably each include an inner surface such that the inner surfaces include a plurality of alternating projections and recesses so that the projections are received within the recesses in an insertion position. Alternatively, the implant may include a plurality of substantially non- flexible bodies and a plurality of substantially flexible links interconnecting the bodies. The non-flexible bodies include a plurality of facets and/or abutment surfaces.
Abstract:
Packages for the rehydration of implants are described, wherein the package may contain a first chamber containing a rehydration fluid, a second chamber containing an implant, and a barrier configured to be affected without compromising the sterility of the package. The rehydration fluid may engage and rehydrate the implant after the barrier is ruptured. Methods of use are also described.
Abstract:
The present invention relates to plugs (10,560) for filling vacancies in bone tissue. The plugs (10,560) include a body (12,566) and at least one endcap (14,16,562,564) that are coupled together and may be formed from bone. The body (12,566) of the plug (10,560) may be a sleeve (202,566), and the plug (10,560) may further include an insert (572) configured and dimensioned to be received in the sleeve (202,566).

Abstract:
An intervertebral spacer implant is provided with a retention mechanism to help alleviate expulsion and movement of the implant when placed in the spine while providing an implant that is easier to insert in the spine. In one embodiment the retention mechanism comprises a keel on at least one of the inferior or superior faces of the spacer implant preferably extending in an anterior-posterior direction. In another embodiment the implant comprises a spacer and a plate, the plate comprising a supplemental or alternative retention mechanism. In one embodiment the retention mechanism comprises one or more holes in the anterior end of the plate that are directed toward the superior, inferior or both endplates of adjacent vertebrae. In yet another embodiment, the retention mechanism comprises one or more blades that are in a first position when inserted and are preferably rotated to a second position that engages the superior and inferior vertebrae.
Abstract:
Implants and methods for augmentation, preferably by minimally invasive procedures and means, of body tissue, including in some embodiments repositioning of body tissue, for example, bone and, preferably vertebrae are described. The implant may comprise one or more chain linked bodies inserted into the interior of body tissue. As linked bodies are inserted into body tissue, they may fill a central portion thereof and for example in bone can push against the inner sides of the cortical exterior surface layer, for example the end plates of a vertebral body, thereby providing structural support and tending to restore the body tissue to its original or desired treatment height. A bone cement or other filler can be added to further augment and stabilize the body tissue. The preferred implant comprises a single flexible monolithic chain formed of allograft cortical bone having a plurality of substantially non-flexible bodies connected by substantially flexible links.
Abstract:
An allogenic implant for use in intervertebral fusion is formed from one or more two pieces. The pieces are made from bone, and are joined together to form an implant having sufficient strength and stability to maintain a desired distance between first and second vertebrae in a spinal fusion procedure. The implant pieces may be formed of cortical bone and connected by dovetail joints, and at least one cortical bone pin may be provided to lock the pieces together and to add strength to the implant. Teeth are formed on the vertebra engaging surfaces of the implant prevent short-term slippage of the implant.
Abstract:
Packages for the rehydration of implants are described, wherein the package (10) may contain a first chamber (20) containing a rehydration fluid (24) , a second chamber (22) containing an implant (26) , and a barrier (30) configured to be affected without compromising the sterility of the package. The rehydration fluid (24) may engage and rehydrate the implant (26) after the barrier (30) is ruptured. Methods of use are also described.
Abstract:
The present application is directed to a spinal implant (10) , preferably a bioresorbable spinal implant, for insertion between vertebrae bodies. The implant preferably includes an anterior surface (12) , a posterior surface (14) , first and second lateral surfaces (16,18) extending therebetween, a superior surface (20) for engaging one of the vertebrae bodies, an inferior surface (22) for engaging the other vertebrae body, and a central bore (30) which extends from the superior surface to the inferior surface. The central bore preferably has a generally lobe- shaped footprint. The anterior surface of the implant preferably includes a pair of vertical channels (40) sized and configured to engage an insertion instrument and the superior surface preferably has a convexly curved surface extending substantially from the anterior surface to the posterior surface while the inferior surface preferably has a substantially constant taper extending from the anterior surface to the posterior surface.
