[1] With the ever decreasing diameters of delivery systems, self-expanding metal mesh stents can be easily inserted in an outpatient procedure using conscious sedation. And, with advancement in ...

The use of drug-eluting stents (DES) has become widespread as a result of their superior revascularization rates compared with those of bare-metal stents (BMS). 1 DES are increasingly being used ...

Stents are made of tiny, expandable tubes of metal alloy and are highly effective at restoring normal blood flow when there's a blockage, therefore increasing blood flow to the heart muscle.

However, traditional metal stents may cause restenosis—a re-narrowing of the artery—due to excessive smooth muscle cell proliferation one month after implantation. Drug-eluting stents are ...

Purpose: The mechanism of action and pharmacokinetics of sirolimus when used as part of a drug-eluting stent (DES) and the efficacy and cost of using DESs versus bare-metal stents are discussed.
