A type of stent where a coating releases a drug. This might be an antimicrobial substance or with vascular stents a drug with anti-proliferative properties.

In the indication of percutaneous coronary intervention second generation everolimus-eluting stents are superior to paclitaxel-eluting stents[1]. Sirolimus-eluting stents seem better than paclitaxel-eluting stents in non-diabetics[2]. The technology continues to evolve in terms of strut thickness and biodegradability. The BIO-RESORT trial reinforced that very thin strut biodegradable polymer everolimus-eluting or sirolimus-eluting stents are effectively equivalent in outcomes and very similar to durable polymer zotarolimus-eluting stents meaning that biodegradability may not significantly alter outcome[3]
