Coronary stent

Illustration of inserting a coronary stent

A stent is a small, coiled wire-mesh tube. During a procedure called angioplasty, the stent is inserted into a blood vessel and expanded using a small balloon. A stent is used to open a narrowed or clotted blood vessel, most often an artery in the heart.
