Patent number: 7513912Abstract: This invention provides for a novel orthopedic prosthesis, specifically a prosthetic tibial component for a prosthetic total knee joint, that comprises two constructs, one being a metal base construct that engages the bone and the other being a polyethylene bearing construct that attaches to the metal base construct and articulates with a femoral prosthetic component on the opposing side of the joint. The metal base construct is composed of two different metals, one of which engages the bone surface and the other of which engages the polyethylene bearing construct. Each of these metals is selected so that its characteristics are well suited to its particular function. More particularly, the first metal (i.e., the one that engages the bone surface) is selected so as to provide a superior bone-engaging face, while the second metal (i.e., the one that engages the polyethylene bearing construct) is selected so as to provide a superior polyethylene-engaging face.Type: GrantFiled: March 13, 2007Date of Patent: April 7, 2009Assignee: Hayes Medical, Inc.Inventors: Daniel E. E. Hayes, Jr., Alfred S. Depres, III

Patent number: 7445640Abstract: Systems and methods are described for implants with composite coatings to promote tissue in-growth and/or on-growth. An implant includes: a substrate; a structured surface formed on at least a portion of the substrate; and a biocompatible coating deposited on at least a fraction of the structured surface. The systems and methods provide advantages in that the implant has good biocompatibility while the biocompatible coating has good strength.Type: GrantFiled: January 10, 2006Date of Patent: November 4, 2008Assignee: Hayes Medical, Inc.Inventors: Alfred S. Despres, III, Eugene J. Elwood, Robert R. Aharonov, Peter Ehlers, Knut Andersen

Publication number: 20080114462Abstract: An orthopaedic joint prosthesis may include a first component, a bearing component, and a third component. The first component has a base and a keel protruding from the base to extend into a first bone. The keel's longitudinal axis is offset from a geometric center of the base. The base has a first articular surface and the bearing component has a second articular surface shaped to articulate with the first articular surface. A feature unitary with the first component reversibly attaches to the bearing component. The bearing component has a third articular surface shaped to articulate with a fourth articular surface on the third component. A distraction feature of the bearing component is shaped to provide alignment and/or distraction between the first articular surface and the fourth articular surface during insertion of the bearing component into a joint space between the first and second bones.Type: ApplicationFiled: November 9, 2006Publication date: May 15, 2008Applicant: Hayes Medical, Inc.Inventors: Michael Guidera, Michael A. Serra, Daniel F. Justin, Chad W. Lewis

Patent number: 7291176Abstract: This invention provides apparatus and a method for assembling a modular hip implant where the desired orientation of the neck component is uniquely determined during the trialing phase of the operation, and that same desired orientation is accurately reproduced during the implantation phase of the actual hip implant device.Type: GrantFiled: May 9, 2003Date of Patent: November 6, 2007Assignee: Hayes Medical, Inc.Inventors: Michael A. Serra, Shaun B. Hanson, Alfred S. Despres, Robert German

The metal base is composed of two metals, one of which engages the bone surface and the other of which engages the polyethylene bearing. Each of the metals is selected for its function. The first metal is selected to provide a superior bone-engaging face, while the second metal is selected to provide a superior polyethylene-engaging face. By combining the different material characteristics of two different metals there is formed a superior bone-engaging face and a superior polyethylene-engaging face.Type: GrantFiled: November 25, 2003Date of Patent: March 13, 2007Assignee: Hayes Medical, Inc.Inventors: Daniel E.

Patent number: 5902340Abstract: The invention provides a modular three-component assembly for replacing a portion of a patient's femur or humerus. A neck component attaches directly to a stem component that inserts into the bone, and a body component that also inserts into the bone is attached to the neck component and/or to the stem component. Methods for assembling the prosthesis are also provided, wherein the stem component is inserted within the body component, and the stem component is joined to the neck component. The prosthesis may be constructed from the components outside of the patient, or, components of the prosthesis may be inserted into the patient prior to final assembly of the prosthesis during surgery.Type: GrantFiled: October 14, 1997Date of Patent: May 11, 1999Assignee: Hayes Medical, Inc.Inventors: Patrick M. White, Daniel E. E. Hayes, Jr., Robert-Jan Enzerink

Patent number: RE37277Abstract: A tibial prosthetic implant includes a base or base plate with an offset tibial stem. The base includes an inferior surface adapted to abut a resected surface of a patient's tibia and forms a base for articulating surfaces adapted to articulate with the patient's femoral condyles. The longitudinal center axis of the tibial stem extends from the inferior surface of the base and is offset from a center of the base. The offset places the stem in position to extend into the central canal of the tibia so that it does not substantially interfere with the cortical bone when the inferior surface of the base substantially abuts and aligns with the resected surface of the tibia.Type: GrantFiled: September 18, 1995Date of Patent: July 10, 2001Assignee: Hayes Medical, Inc.Inventors: James L. Baldwin, Steven I. Whitlock
