AN IMPROVED COBALT-NICKEL-CHROMIUM BIOCOMPATIBLE ALLOY FOR IMPLANTABLE MEDICAL DEVICES

摘要

A biocompatible solid-solution alloy may be formed into any number of implantable medical devices. The solid-solution alloy comprises a combinatio n 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 and/or Silicon content.
