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.
A stent is a wire metal mesh tube used to prop open an artery during angioplasty. The stent is collapsed to a small diameter and put over a balloon catheter. Itâs then moved into the area of the blockage. When the balloon is inflated, the stent expands, locks in place and forms a scaffold. This holds the artery open.
