  • Patent number: 9820856
    Abstract: An orthopedic joint prosthesis may include a first component, a bearing component, and a third component. The first component has a base and a keel protruding from the base to extend into a first bone. The keel's longitudinal axis is offset from a geometric center of the base. The base has a first articular surface and the bearing component has a second articular surface shaped to articulate with the first articular surface. A feature unitary with the first component reversibly attaches to the bearing component. The bearing component has a third articular surface shaped to articulate with a fourth articular surface on the third component. A distraction feature of the bearing component is shaped to provide alignment and/or distraction between the first articular surface and the fourth articular surface during insertion of the bearing component into a joint space between the first and second bones.

  • Publication number: 20150142110
    Abstract: Systems for single tunnel, double bundle anterior cruciate ligament reconstruction include implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. The instruments are also used to exercise and insert the ligament graft constructs. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on a single femoral tunnel, single or double tibial tunnels, and one or more ligament grafts.

  • Patent number: 8632568
    Abstract: A suture anchor and inserter arrangement, including a suture anchor for implanting in hard tissue, such as bone, and an inserter device for installing the suture anchor in hard tissue. The suture anchor carries thereon a suture-engaging structure formed from suture, which structure cooperates with working suture associated with the inserter device so as to attach the working suture to the suture anchor.

  • Publication number: 20130304124
    Abstract: A spinal plating system for vertebral fixation includes a plate, a compression screw, multiple fixation members and polyaxially adjustable locking rings. The plate is shaped to conform to the curvature of the spine and the surfaces of the vertebral bodies. The compression screw fits through an insert, and together they are guided by the plate as the screw is driven into one of the vertebrae, producing compression between the adjacent vertebrae. A retaining lip on the plate prevents backout of the compression screw. The polyaxial locking rings can be polyaxially pivoted to attain a desired orientation, and are lockable to the plate to maintain the orientation. The fixation members fit through openings in the polyaxial locking rings and the plate to fix the plate to the vertebrae. Locking the polyaxial locking rings fixes the position of the fixation members relative to the plate, and prevents backout of the fixation members.

  • Publication number: 20070179609
    Abstract: The present invention provides integration between an implant system and therapeutic agent delivery system. The implant may include a prosthesis that restores biomechanical function while decreasing long-term disability and pain by replacing damaged or degenerate tissues, or a reconstructive implant such as a bone plate. The therapeutic agent delivery system may include one or more channels either permanently or reversibly attached to the implant. The channels may receive medication from an external pump via a percutaneous catheter. The channels deliver the medication to one or more medicating surfaces of the implant to treating proximate tissues.
