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.

This oxygen attracted the cellulose-producing bacteria, guiding them directly onto the metal stent’s surface. Over several days, the bacteria gradually produced a dense, fiber-based network that ...

Background and Aims: Technical limitations of conventional endoscopes and delivery systems frequently hamper palliative endoscopic placement of self-expandable metal stents for malignant small ...

when compared with bare-metal stents (BMSs), in patients undergoing percutaneous coronary intervention. Use of these stents rapidly became widespread in clinical practice. However, reports of ...
