  • Patent number: 9114023
    Abstract: A method and apparatus is provided for use in spinal fusion procedures. An interbody fusion device has a first piece that is a load bearing device designed to bear the axial loading from the end plates of adjacent vertebrae. A second piece of the interbody fusion device is a retention device whose function is to prevent migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. The device includes a snap in mechanism for coupling the first piece to the second piece.

  • Patent number: 8795373
    Abstract: A method and apparatus is provided for use in spinal fusion procedures. A one or two piece interbody fusion device has a fusion bearing component designed to bear the axial loading from the end plates of adjacent vertebrae. An optional retention piece prevents migration of the load bearing device. One or more fasteners secure the retention device to the vertebrae above and below the load bearing device. The fasteners cause the end plates of the vertebrae to compress the end plates to the load bearing device to facilitate proper fusion. An anti-backout mechanism prevents the fasteners backing out.

  • Publication number: 20140114419
    Abstract: The invention comprises a combination of biological elements that will naturally remodel in vivo based on applied mechanical forces. The final composition will possess mechanical properties similar to cartilage or a disc, and significantly less stiff than bone or implants comprised of metals or plastics. The equilibrium stress conduction will minimize unnatural forces on neighboring healthy discs.
