  • Polymer based joint implants and method of manufacture
    Patent number: 10058429
    Abstract: A method and implant based on injection molding techniques. The method produces polymeric components suitable for implantation with a structure and mechanical properties close to those of natural bone tissue. In a variant, method for making an implant or component thereof includes forming a standard shape foamed blank, and over-molding a thin layer of non-foamed PEEK material onto the standard shaped foamed blank to obtain a final implant component geometry, whereby the blank is completely encapsulated by the over-molded layer.
    Type: Grant
    Filed: March 14, 2014
    Date of Patent: August 28, 2018
    Inventors: Jean-Luc Thuliez, John Nicholas Ayliffe
