A stent is a small mesh tube that’s used to treat narrowed or weakened arteries in the body.

You may have a stent placed in an artery as part of a procedure called angioplasty (AN-jee-oh-plas-tee). Angioplasty can restore blood flow through narrowed or blocked arteries. Stents help prevent arteries from becoming narrowed or blocked again in the months or years after treatment with angioplasty. You may also have a stent placed in a weakened artery to improve blood flow and to help prevent the artery from bursting.

Stents are usually made of metal mesh, but sometimes they’re made of fabric. Fabric stents, also called stent grafts, are used in larger arteries. Some stents are coated with medicines that are slowly and continuously released into the artery. These medicines help prevent the artery from becoming blocked again.

Clinical study shows efficacy, safety of novel drug-eluting stent with improved radiographic visibility

This first randomized clinical study of a polymer-coated zotarolimus-eluting stent (Resolute Onyx) that utilizes a novel thin-strutted metallic platform allowing for better x-ray visibility was shown to be non-inferior to an ultrathin-strutted bioresorbable polymer-coated sirolimus-eluting stent (Orsiro) that uses a cobalt-chromium strut platform.
