  • Patent number: 9138209
    Abstract: An annulus repair system is provided. This repair system may cover a hole or opening in the annulus or repair a defect or damage to the annulus. In one embodiment, the annulus repair system comprises a blocking component that covers a hole in the annulus, a stabilizing component that helps stabilize the blocking component and a suturing material that connects the two components together. In certain embodiments, the annulus repair system may further comprise a cannula for guiding the blocking component, the stabilizing component and at least a portion of the suturing material through body tissue and into the disc space. Methods for utilizing the annulus repair system of the present invention also are provided.

  • Patent number: 8814879
    Abstract: Systems and methods for repairing annulus defects include at least one blocking member positionable in or adjacent to the annulus defect, at least one attachment portion for securing the blocking member to adjacent tissue, and instruments for placing and engaging the blocking member in and/or adjacent to the annulus defect. The blocking member extends at least partially across the annulus defect for repair of the defect and/or retention of nucleus material, one or more implants, bio-compatible materials or device, and/or other objects positioned in the disc space.

  • Patent number: 8137383
    Abstract: A method for securing first and second tissues with a suture anchor. The steps include forming a borehole in the first tissue; threading a suture through the second tissue forming a loop in the suture with the tissue thereby secured in the loop, the loop defining two suture portions; attaching the two suture portions to the anchor whereby the two suture portions are threaded through the anchor and initially movable with respect to the anchor; and providing a force to a shaft of the anchor, the force causing clamping of the two suture portions in the anchor and deformation of a deformable portion of the anchor to cause the deformable portion to engage a wall of the borehole thereby to secure the suture anchor in the first tissue and the loop holding the second tissue to the suture anchor.

  • Patent number: 8128591
    Abstract: A multiple component cartridge includes a barrel defining a chamber and a longitudinal axis. A first plunger is disposed within the chamber and in sealing engagement with the barrel. The first plunger includes at least one member and is movable relative to the barrel such that the at least one member is configured for movement relative to the first plunger to facilitate passage of at least a first component through the first plunger. A second plunger is disposed within the chamber and in sealing engagement with the barrel. The second plunger includes at least one member and is movable relative to the barrel such that the at least one member of the second plunger is configured for movement relative to the second plunger to facilitate passage of at least a second component through the second plunger.
