Publication number: 20100262245Abstract: Disclosed is a delivery system for an intervertebral spacer and a bone grafting material in the form of a unitary device which comprises a spacer disengagingly attached to a hollow handle. The handle comprises a chamber and bone grafting material-advancing means within the chamber for introducing the bone grafting material from the chamber into and around the spacer and the intervertebral spaces. The handle is disengageable from the spacer after serving its purpose of facilitating placement of the spacer and the discharge of the bone grafting material into the spacer and the intervertebral space. The intervertebral spacer implant portion is attached to the handle portion at the exit port of the chamber, the point of attachment constituting the entry port of the intervertebral spacer implant portion.Type: ApplicationFiled: February 17, 2010Publication date: October 14, 2010Inventors: Arthur A. Alfaro, Marc Burel

Patent number: 7662185Abstract: A multipart intervertebral implant is provided which includes an implant portion and an implant extender portion. The implant portion and the implant extender portion can be fastened together using any known fastening means including pins, interlocking structure (e.g., dovetail, tongue and groove, etc.), adhesives, etc. The size of the implant extender portion can be selected during a surgical procedure to provide an implant suitable for a particular intervertebral receiving bed. An intervertebral implant is also provided which may be formed from a multiplicity of implant sections which are fastened together to provide an implant having a desired length. Implants having surface configurations which more closely correspond to the configuration of vertebral endplates are also provided.Type: GrantFiled: August 28, 2003Date of Patent: February 16, 2010Assignee: Osteotech, Inc.Inventors: Arthur A. Alfaro, Lawrence A. Shimp, James L. Russell, John W. Boyle, Erik O. Martz, Daniel E. Rosenthal, John W. Morris

Publication number: 20030060825Abstract: There is provided a combined two-part intervertebral implant (10) configured to restore the spacing between adjacent vertebrae. The implant (10) generally includes a spacer ring (12) having upper and lower vertebral engaging surfaces and a bore for receipt of a locking element (14). The implant (10) further includes a locking element (14) which is engageable within the spacer ring (12) and has a diameter or height greater than the thickness of the spacer ring. In one embodiment, the spacer ring (12) may be formed as a C-shaped element (16). In an alternative embodiment, the spacer ring may be formed as an intact ring (42) having a side bore (44) for receipt of the locking element. One or both parts of the implant (10) may be partially or wholly surface demineralized to provide a flexible surface on implant. A method of using the spacer ring (12) and locking element (14) to secure the assembled implant between adjacent vertebrae is also disclosed.Type: ApplicationFiled: September 9, 2002Publication date: March 27, 2003Inventors: Arthur A. Alfaro, Lawrence A. Shimp, John Boyle, Perry Geremakis, James Russell, Nelson L. Scarborough

Patent number: 6241765Abstract: A prosthetic heart valve is disclosed which has a rigid shoulder with staple receiving means. Using the staple receiving means of the shoulder, the heart valve may be secured within the heart by stapling the shoulder of the prosthesis to the patient's tissue. Such a prosthesis is advantageous in that it may be secured in a much shorter time period than conventional valves thereby reducing the risks and complications of surgery.Type: GrantFiled: July 15, 1999Date of Patent: June 5, 2001Assignee: Sulzer Carbomedics Inc.Inventors: Charles D.
