Abstract:
An apparatus and method for joining members together using a self-drilling screw apparatus or stapling apparatus are disclosed. The screw apparatus includes a shell and first and second first screw members having tapered ends and threaded bodies that are disposed within the shell. A drive mechanism rotatably drives the first and second screw members from the shell in opposite directions and causes the screw members to embed themselves in the members to be joined. The screw apparatus can be used to join members such as bones, portions of the spinal column, vertebral bodies, wood, building materials, metals, masonry, or plastics. The stapling apparatus includes first and second lever arms rotatably joined together at a fulcrum, and the lever arms rotate in opposite directions. First and second cartridges are disposed at the ends of the lever arms. Each cartridge is capable of holding a staple including a bracket, a nail member and an alignment slot. When the ends of the lever arms are rotated towards each other the staples from the cartridges are interlocked. The staples can be also be used to join members such as bones, portions of the spinal column, or vertebral bodies.

Claim (Index 21):
An artificial intervertebral implant comprising:\n a fusion cage comprising a top wall, a bottom wall, a first sidewall, and a second sidewall, wherein the top wall, bottom wall, first sidewall, and second sidewall together define a first vertebral body facing surface and a second vertebral body facing surface opposite of the first vertebral body facing surface, wherein the fusion cage defines at least one bone material slot extending from the first vertebral body facing surface through the fusion cage to the second vertebral body facing surface; a first anchor having a first shaft and a first pointed tip, wherein the first anchor is movable from a first retracted position that is substantially inside the fusion cage to a first anchored position with the first pointed tip of the first anchor extending out of the fusion cage past the first vertebral body facing surface; a second anchor having a second shaft and a second pointed tip, wherein the second anchor is movable from a second retracted position that is substantially inside the fusion cage to a second anchored position with the second pointed tip of the second anchor extending out of the fusion cage past the second vertebral body facing surface; and an expansion mechanism operably connected to the first anchor and the second anchor, wherein the expansion mechanism comprises a tool engaging head and a rotatable shaft extending from the tool engaging head, wherein the tool engaging head and the rotatable shaft are configured to rotate about a common axis that extends from the top wall to the bottom wall, wherein the tool engaging head is positioned in a hole defined in the top wall of the fusion cage with the rotatable shaft extending along the common axis in a direction toward the bottom wall of the fusion cage, wherein the tool engaging head has an outer rim surrounding a tool receiving cavity sized and configured for receiving a tool into the tool receiving cavity when the tool extends to the tool receiving cavity along an angle that is substantially equal to the common axis of the tool engaging head and the rotatable shaft, wherein the rotatable shaft operably connects the tool engaging head to the first and second anchors such that rotation of the tool engaging head simultaneously moves the first anchor to the first anchored position and the second anchor to the second anchored position.
