  • Patent number: 11219537
    Abstract: A system and method of processing bone is disclosed. A tissue separator is utilized to separate tissue comprising at least one of muscle, periosteum and connective tissue from bone in a safe, sterile and efficient manner. In one aspect, the particle reducer can include an impeller positioned with respect to a cutting surface on a drum. At least one of the impeller and the drum is rotated by a power source such that harvested tissue frictionally engages the cutting surface. In another aspect, a source of pressurized fluid can be directed at tissue to separate bone from non-bone tissue.
    Type: Grant

  • Patent number: 9931079
    Abstract: A clamp for securing a terminal end of a wire to a surface electrode formed on a cylindrical tube includes a first semicylindrical element. A second semicylindrical element is configured to be attached to the first semicylindrical element to form a tubular clamp structure that is adapted to be clamped around the cylindrical tube. The tubular clamp structure includes an interior surface configured to securely hold a terminal end of a wire against a surface electrode formed on the cylindrical tube.

  • Patent number: 6533789
    Abstract: A device for rotational stabilization of bone segments comprising a bone plate, a bone lag screw, and a locking collar. The bone lag screw has a bone-engagement end, a distal end, and a keyed cross-sectional profile, the bone-engagement end configured for engaging a first bone segment. The bone plate has a flat portion for engaging a second bone segment and a barrel portion having an internal bore for slidably receiving the lag screw.
