  • Publication number: 20130211460
    Abstract: A bone plate and system is provided. The bone fixation plate conforms to the contour of an irregularly shaped bone and eliminates the need for pre-bending or intraoperative bending of the plate. The bone plate is applied to the bone in a generally flat condition and the process of installing and tightening the bone screws in the prescribed order serves to contour the plate to the underlying bone while providing sufficient strength to effect bone healing. The geometry of the plate allows the plate to follow the contour of an irregularly shaped bone, preventing prominence and patient palpability and streamlining the surgical procedure.

  • Patent number: 8080042
    Abstract: Strip fasteners and cranial plugs for use in reattaching a skull flap removed during brain surgery and methods of using the same. The strip fasteners are flexible and can be shaped to follow the perimeter contour of the skull flap. The cranial plugs can be used to reattach the skull flap or they can be installed after the skull flap is reattached using the strip fasteners. In some embodiments, the cranial plug(s) and strip fasteners can be installed at the same time. The strip fasteners and cranial plugs are designed to encourage bone growth and healing of the skull flap and they can be used to deliver medication and bone growth enhancement compositions to the surgical site.

  • Patent number: 6916483
    Abstract: Bioabsorbable modular drug delivery devices having shapes and sizes adapted to be inserted within a mating receptacle on the surface of an implantable prosthesis are disclosed. The devices may be attached to one another to create custom drug delivery devices having controllable drug release characteristics that depend on the composition of individual modules comprising the device. The modules may be cylinders, disks, tiles or tubes comprised of a bioabsorbable polymer and a therapeutic agent. The therapeutic agent(s) may be homogeneously distributed throughout the polymeric body of the device or contained within a cavity within a module comprising the device, or both. The device(s) may be threaded or attached to a prosthesis by a biodegradable adhesive. The modular devices may also be formed into tapered plugs for insertion into a mating receptacle.
