A QUATERNARY COBALT-NICKEL-CHROMIUM-MOLYBDENUM FATIGUE RESISTANT ALLOY FOR INTRAVASCULAR 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 improve its fatigue resistance while retaining the characteristics required for implantable medical devices. The biocompatible solid-solution alloy is a quaternary cobalt-nickel-chromium-molydenum alloy having substantially reduced titanium content.
