Using catheters, interventional radiologists open vessels (including with angioplasty) and then place small tube-like devices called stents to maintain the opening of the vessel (or, in other words, to make sure that vessel's lumen stays patent). Specialists perform this additional.
Drug-eluting stents, once thought to increase heart attack risk, are generally considered safe if used properly. Stents are small mesh tubes inserted to keep arteries open after a procedure called angioplasty (percutaneous coronary intervention, or PCI). Drug-eluting stents have a polymer coating over mesh that emits a drug over time to help keep the blockage from recurring.
