摘要

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.
