  • Platinum Enhanced Alloy and Intravascular or Implantable Medical Devices Manufactured Therefrom
    Publication number: 20120004718
    Abstract: A platinum enhanced radiopaque alloy particularly suitable for manufacture of implantable and/or intravascular medical devices. A stent is one preferred medical device which is a generally tubular structure that is expandable upon implantation in a vessel lumen to maintain flow therethrough. The stent is formed from the alloy which has improved radiopacity relative to present utilized stainless steel alloys. This alloy preferably contains from about 2 wt. % to about 50 wt. % platinum; from about 11 wt. % to about 18 wt. % chromium; about 5 wt. % to about 12 wt. % nickel and at least about 15 wt. % iron.
