  • Spinal intervertebral implant and method of making
    Patent number: 6706067
    Abstract: A C-shaped or ring shaped implant formed of cortical bone has its C-shaped or inner channel filled with a bone promoting material which is preferably demineralized bone fibers formed as a flexible wet sheet or may be cancellous bone, pressed bone fibers formed from demineralized cortical bone chips soaked in acid, or a flex material formed of demineralized bone growth promoting bone fibers. The discrete bone filler element may be secured by a bonding agent, pins or screws, metal, polymer or bone material. The bone filler material is preferably bonded by filling a section of a long bone medullary cavity with wet bone fibers and then drying the fibers to bond them to the outer bone. A filled bone ring may be sliced to form annular filled sections which are then divided into mirror image C-shaped halves each forming an implant. Flex material of compressed bone fibers may be formed with an opening shaped to receive a cortical bone implant element having a C-shaped channel.

  • Insert for shielded trocar
    Patent number: 5248298
    Abstract: An insert is provided to be attached to a shield on a surgical trocar obturator handle. The insert is actuated by the surgical trocar cannula handle so that it causes the shield to expose the sharpened obturator tip after insertion of the obturator and shield within the cannula. After usage, the insert is deactivated so that the shield again covers the obturator. The obturator can then be removed from the cannula handle and obturator shield, and the obturator handle can be discarded safely.
