Implantable medical devices

摘要

Implants made from a cobalt chromium alloy have a surface that is exposed to one or more formulations that results in the surface becoming texturized so as to include a plurality of surface pits. The average pit size opening can range, for example, from 40 nm to about 10 µm. The modified surfaces can promote growth of a calcium phosphate layer, which can be accelerated relative to conventional techniques.
