  • Prosthetic device and method of making the same
    Patent number: 6976999
    Abstract: A method of making a non-modular prosthetic device for a joint arthroplasty. The method comprises molding a polymer interlayer between a porous metal structure and a polymer insert, wherein the insert generally comprises conventional or cross-linked ultra high molecular weight polyethylene (“UHMWPE”).
    Type: Grant
    Filed: November 19, 2002
    Date of Patent: December 20, 2005
    Assignee: Zimmer Technology, Inc.
    Inventors: Steven Charlebois, Cheryl Blanchard, Michael Hawkins, Dale Swarts
  • Method for attaching a porous metal layer to a metal substrate
    Publication number: 20050242162
    Abstract: A method for attaching a porous metal layer to a dense metal substrate, wherein the method is particularly useful in forming orthopedic implants such as femoral knee components or acetabular cups. The method, in one embodiment thereof, comprises providing a structured porous layer; providing a dense metal substrate; providing a binding mixture; applying the binding mixture to the exterior of the substrate; placing the porous layer against the substrate such that the binding mixture is disposed there between forming an assembly; and heat treating the assembly to metallurgically bond the porous layer to the substrate.
