Patent number: 11219537Abstract: 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: GrantFiled: December 19, 2019Date of Patent: January 11, 2022Assignee: MEDTRONIC XOMED, INC.Inventors: Michael L. Koltz, Louis M. Shadeck, David John Little, II, Gerould Winthrop Norman, Dana A. Oliver

Patent number: 9931079Abstract: 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.Type: GrantFiled: January 4, 2012Date of Patent: April 3, 2018Assignee: Medtronic Xomed, Inc.Inventors: Wenjeng Li, Steven W. Bennett, David John Little, II, Maria Charles Vijay Stanislaus, David C. Hacker

Patent number: 6533789Abstract: 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.Type: GrantFiled: April 4, 2000Date of Patent: March 18, 2003Assignee: Synthes (USA)Inventors: Harry Thomas Hall, IV, David John Little, II, Stephen J.
