ABSTRACT:
A method for coating implantable medical devices, such as orthopaedic prostheses, with a dense, substantially non-porous oxide coating so as to minimize ion release therefrom, and the product of that process is described. The prosthesis is subjected to anodic electrolytic deposition in an alcoholic electrolyte containing alkali metal nitrate or nitric acid. In a preferred embodiment the anodically coated prosthesis is also coated with a bioactive layer of calcium phosphate.
