   Most current FDA-approved drug-eluting stents use sirolimus (also known as rapamycin), everolimus and zotarolimus.

   The 2006 SIROCCO trial compared the sirolimus drug-eluting stent with a bare nitinol stent for atherosclerotic lesions of the subsartorial artery, reporting restenosis at 2 year follow-up was 22.9% and 21.1%, respectively. [21] A 2009 study compared bare nitinol stents with percutaneous transluminal angioplasty (PTA) in subsartorial artery ...
