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.
The stent stays in the artery permanently, holds it open, improves blood flow to the heart muscle and relieves symptoms (usually chest pain). Within a few weeks of the time the stent was placed, the inside lining of the artery (the endothelium) grows over the metal surface of the stent. Source.
