Augmentation Device For Joint Prosthesis

View page
US Patent:
60050187, Dec 21, 1999
Filed:
Nov 1, 1996
Appl. No.:
8/741581
Inventors:
Gerald J. Cicierega - Bridgewater MA
Robert C. Hurlburt - Whitman MA
Michael J. O'Neil - West Barnstable MA
Assignee:
Johnson & Johnson Professional, Inc. - Raynham MA
International Classification:
A61F 238
US Classification:
523 20
Abstract:
An augmentation system for an implantable bone prosthesis, such as a femoral component of a knee joint prosthesis, includes an augmenting block having an aperture disposed therein. A collet having an expandable distal end, extending beyond one surface of the augmenting block, is positioned within the aperture. The proximal end of the collet includes a threaded cavity that receives a set screw which is adapted to communicate with the collet to expand and contract the collet. The distal end of the collet is adapted to fit within a mounting cavity of a joint prosthesis. With the augmenting block placed on the appropriate surface of the joint prosthesis, the distal end of the collet is positioned within the mounting cavity. Tightening of the set screw causes the distal end of the collet to expand, thus frictionally and/or mechanically engaging the interior walls of the mounting cavity to firmly secure the augmenting system to the prosthesis.

US Patent:
59849690, Nov 16, 1999
Filed:
Nov 28, 1995
Appl. No.:
8/563775
Inventors:
Frank D. Matthews - Walpole MA
Robert S. Brown - Boston MA
Gerald J. Cicierega - Bridgewater MA
Robert Hurlburt - Whitman MA
Michael J. O'Neil - West Barnstable MA
Assignee:
Johnson & Johnson Professional, Inc. - Raynham MA
International Classification:
A61F 238
US Classification:
623 20
Abstract:
An augmentation system for an implantable bone prosthesis, such as a femoral component of a knee joint prosthesis, includes an augmenting block having an aperture disposed therein. A collet having an expandable distal end, extending beyond one surface of the augmenting block, is positioned within the aperture. The proximal end of the collet includes a cavity that receives an expansion pin that is adapted to communicate with the collet to expand the collet. The distal end of the collet is adapted to fit within a mounting cavity of a joint prosthesis. With the augmenting block placed on the appropriate surface of the joint prosthesis, the distal end of the collet is positioned within the mounting cavity. Advancement of the expansion pin causes the distal end of the collet to expand, thus frictionally and/or mechanically engaging the interior walls of the mounting cavity to firmly secure the augmenting system to the prosthesis. The expansion pin can include threads which mate with corresponding threads within the cavity of the collet.
