A wire or other tube used to hold open a tubular organ. With advances in metallurgy we now have self-expanding metal stents (SEMS).
Most commonly used in coronary arteries, but also in the common bile duct, ureters and trachea and in palliation of GI malignancies, e.g. oesophageal and colonic carcinoma (colonic self-expanding metal stents).
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. Sirolimus-eluting stents seem better than paclitaxel-eluting stents in non-diabetics.
