Patent number: 7857814Abstract: A cutting tool for creating resected surfaces of bone during arthroplasty procedures has a single offset handle arm that presents a narrower effective width than a width of the cutting profile of the cutting tool along a longitudinal axis of the cutting profile. Preferably, the single offset handle arm creates a cutting tool with a generally L-shaped outline simultaneously accounting for soft tissue/incision geometry and bony geometry to accommodate both in facilitating ease of use and minimal displacement of soft tissue during cutting. The cutting tool can be snaked into position through an incision approximately the size of the width of the handle arm, instead of requiring an incision that is essentially the width of the cutting path of the cutting tool. In alternate embodiments, the cutting tool is a milling tool, a wireplasty cutting tool, a band saw or reciprocating cutting tool.Type: GrantFiled: March 8, 2005Date of Patent: December 28, 2010Assignee: Hudson Surgical Design, Inc.Inventor: Timothy G. Haines

Patent number: 7854766Abstract: A total artificial expansile disc and a method for posterior insertion between a pair of vertebral endplates are disclosed. The total artificial expansile disc includes at least one pair of substantially parallel plates that move apart along a first axis, in order to occupy a space defined by the vertebral endplates. In another embodiment, each of substantially parallel plates includes a first plate and a second sliding plate. An expansion device or tool is used to move the substantially parallel pair of plates apart along the first axis. A core is disposed between the pair of plates, and the core permits the vertebral endplates to move relative to one another. A ball limiter or ball extender prevents the core from being extruded from between the substantially parallel plates.Type: GrantFiled: July 17, 2006Date of Patent: December 21, 2010Inventors: Nathan C.
