  • Chemical vapor infiltration apparatus and process
    Patent number: 8956683
    Abstract: The present invention relates to improvements in chemical vapor infiltration processes and devices for depositing a biocompatible material onto a porous substrate to form an orthopedic implant. The substrate may be formed of reticulated vitreous foam and coated with tantalum, niobium, tungsten, or other biocompatible materials.
    Type: Grant
    Filed: June 14, 2012
    Date of Patent: February 17, 2015
    Assignee: Zimmer, Inc.
    Inventors: Joseph R. Vargas, Steven J. Seelman, David B. Roberts
  • Micro-alloyed porous metal having optimized chemical composition and method of manufacturing the same
    Patent number: 8734514
    Abstract: A micro-alloyed porous metal is disclosed having an optimized chemical composition to achieve targeted mechanical properties for use as an orthopaedic implant and a cell/soft tissue receptor. The porous metal may achieve a targeted compressive strength and a targeted ductility, for example. These targeted mechanical properties may allow the porous metal to be densified to a low relative density.
