Abstract
A biocompatible solid-solution alloy may be formed into any number of implantable medical devices. The solid-solution alloy comprises a combination of elements in specific ratios that make it magnetic resonance imaging compatible while retaining the characteristics required for implantable medical devices. The biocompatible solid-solution alloy is a cobalt-chromium alloy having substantially reduced iron, silicon, phosphorus and sulfur content.
