Patent number: 6755841Abstract: An installation tool that is useful for the efficient and effective placement of an article, such as an artificial disc, between adjacent vertebral bodies is provided. The installation tool can be provided as a kit having modular components which allow the surgeon to select from among a variety of components to assemble an installation tool that is optimized for its intended use. The installation tool of the invention generally includes a pair of opposed levers, each of which has a proximal handle portion and a distal portion. A fulcrum is disposed between the two levers to enable proper operation of the tool. The tool further includes a pusher block that is positioned between the two levers and is selectively movable between an initial location distal of the fulcrum and a final location adjacent the distal end of the levers. The pusher block includes a proximal end, a distal end, and a bore extending at least partially therethrough.Type: GrantFiled: December 7, 2001Date of Patent: June 29, 2004Assignee: DePuy Acromed, Inc.Inventors: Robert D.

Patent number: 6726720Abstract: A modular implant that is effective to replace a damaged or degenerated spinal disc is provided. The implant includes a central core member having superior and inferior surfaces, a superior endplate member having a bone-contacting surface and a mating surface effective to mate with the superior surface of the central core member, and an inferior endplate member having a bone-contacting surface and a mating surface effective to mate with the inferior surface of the central core member. The modularity of the implant allows the surgeon to select and properly fit each modular endplate member separately during the surgical procedure, thereby eliminating the need to prepare the endplates of each adjacent vertebrae, and/or the bone-contacting surfaces of the implant.Type: GrantFiled: March 27, 2002Date of Patent: April 27, 2004Assignee: DePuy Spine, Inc.Inventors: Raymond Ross, Michael O'Neil, Mark Boomer
