20100174383CERAMIC LAYERED MEDICAL IMPLANT - A new composition and medical implant made there from comprises a thick diffusion hardened zone, and layered ceramic surface. Orthopedic implants comprising the new composition, methods of making the new composition, and methods of making orthopedic implants comprising the new composition are disclosed.07-08-2010
20110008407COATING AND COATING METHOD - The present invention discloses a coating for a medical implant, wherein at least a part of said coating contains an osseointegration agent and the same and/or a different part of the coating contains an antimicrobial metal agent.01-13-2011
20110014258GRADIENT COATING FOR BIOMEDICAL APPLICATIONS - The present invention provides a coating comprising a bioactive material and an antimicrobial agent, wherein the concentration of said antimicrobial agent varies throughout the thickness of the coating.01-20-2011
20110112646ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE FOR BEARING SURFACES - A prosthetic device may comprise an insert having a first surface configured to contact a first prosthetic component and a bearing surface configured to articulate against a second prosthetic component. The insert comprises an ultra-high molecular weight polyethylene and vitamin E. The vitamin E may have a concentration in the range of 0.02 to 0.12 wt % first mixed with the ultra-high molecular weight polyethylene and then molded with the ultra-high molecular weight polyethylene at a temperature greater than the melting point of the ultra-high molecular weight polyethylene. The ultra-high molecular weight polyethylene and vitamin E may be gamma irradiated with a dosage of radiation between 5 and 20 Mrad. The insert may be machined prior to gamma irradiating the insert in air such that the gamma irradiation, at suitably high dosages, may also sterilize the insert.05-12-2011

20080281429Applications of Diffusion Hardening Techniques - A device, for example a medical implant, and a method of making the same, the device having a metal or metal alloy substrate, for example CoCr, and a diffusion hardened metallic surface, for example a plasma carburized surface, contacting a non-diffusion hardened surface or a diffusion hardened surface having a diffusion hardening species different from that of the opposing surface.11-13-2008
20080289729DIFFUSION-HARDENED MEDICAL IMPLANT - The present invention relates to a new composition and medical implant made therefrom, the composition comprising a thick diffusion hardened zone, and preferably further comprising a ceramic layer. The present invention relates to orthopedic implants comprising the new composition, methods of making the new composition, and methods of making orthopedic implants comprising the new composition.11-27-2008
20090074836DIFFUSION-HARDENED MEDICAL IMPLANT - The present invention relates to a new composition and medical implant made therefrom, the composition comprising a thick diffusion hardened zone, and preferably further comprising a ceramic layer. The present invention relates to orthopedic implants comprising the new composition, methods of making the new composition, and methods of making orthopedic implants comprising the new composition.03-19-2009
20090112331METHOD OF SURFACE OXIDIZING ZIRCONIUM AND ZIRCONIUM ALLOYS AND RESULTING PRODUCT - A coating of blue-black or black oxidized zirconium of uniform and controlled thickness on a zirconium or zirconium alloy material is accomplished through the oxidative treatment of an amorphous zirconium or zirconium alloy substrate having an altered surface roughness. An oxidized zirconium coating of uniform and controlled thickness is especially useful on orthopedic implants of zirconium or zirconium-based alloys to provide low friction, highly wear resistant surfaces on artificial joints, such as, but not limited to, hip joints, knee joints, shoulders, elbows, and spinal implants. The uniformly thick oxidized zirconium surface of controlled depth on prostheses provide a barrier against implant corrosion caused by ionization of the metal prostheses. The invention is also useful in non-articulating implant devices such as bone plates, bone screws, etc.04-30-2009
20090187255CERAMIC METAL COMPOSITE FOR ORTHOPAEDIC IMPLANTS - The invention relates to an orthopedic implant made of a ceramic metal composite. The composite (07-23-2009
20100074789MEDICAL IMPLANTS HAVING A POROUS COATED SUFACE - A process for making a diffusion hardened medical implant having a porous surface is disclosed. The medical implant is made by a hot isostatic pressing process which simultaneously forms that porous surface and the diffusion hardened surface.03-25-2010
20110015756SURFACE ALLOYED MEDICAL IMPLANT - A medical implant is disclosed. The medical implant includes: a first biocompatible metal forming a substrate (01-20-2011
20110139312METHOD OF PROVIDING A ZIRCONIUM SURFACE AND RESULTING PRODUCT - A coating of blue-black or black zirconium of uniform and controlled thickness on a zirconium or zirconium alloy material is accomplished through the treatment of an amorphous zirconium or zirconium alloy substrate, which may have an altered surface roughness. The treatment of amorphous zirconium or zirconium alloy substrates includes oxidation of the substrates. A zirconium coating of uniform and controlled thickness is especially useful in various applications because the uniformly thick zirconium surface of controlled depth provide a barrier against implant corrosion caused by ionization of the metal substrates.06-16-2011
