What are stents made of?

A stent is a small, flexible tube made of either medical grade plastic or expandable wire mesh. There are also drug-eluting stents; these stents may be coated with drugs to have a pharmacological effect on clogged blood vessels or other pathways that have been narrowed or blocked by tumors or obstructions. Stents are implanted in the body to treat a variety of medical conditions.

Stents are expandable metal tubes that are either made out of stainless steel, cobalt chromium or platinum chromium. If they are not drug-eluting they are referred to as bare metal stents. If they are drug-eluting then they are referred to as either durable polymer or bioabsorbable drug-eluting stents.
