  • Method of making an orthopaedic implant having a porous surface
    Patent number: 6544472
    Abstract: A method of forming an orthopedic implant having a porous surface layer thereon. A mask includes a cut-out configured to receive a portion of the implant therein. The implant is placed within the cut-out and thereby masked. A water soluble binder solution is sprayed onto at least a part of the unmasked portion of the implant using a sprayer, thereby forming a binder layer on the implant. The binder solution includes water, ethanol, gelatin, glycerin, and a colorant. A porous layer including a plurality of metallic particles is contacted with the binder layer. The porous layer is bonded with the surface of the implant with a sintering process.
    Type: Grant

  • Method of making an orthopaedic implant having a porous surface using an organic binder
    Patent number: 5926685
    Abstract: The invention is directed to a method of forming an implant having a porous surface using an organic binder compound to enhance the bonding between the porous surface layer and implant. Preferably, the binder is formed from a water-soluble protein that carbonizes during the sintering process to alloy with the metal of the porous surface layer. The porous surface layer may be in the form of beads or of fiber metal and can be preformed to fit with an implant or formed over the surface of the implant.
