Coronary artery stent

A coronary artery stent is a small, metal mesh tube that is placed inside a coronary artery to help keep the artery open. To place the stent, a small sheath (plastic tube) is placed in the groin or wrist artery. A catheter is guided through the artery into the part of the coronary artery that is blocked. The stent is inserted along with a balloon catheter and expands when the balloon is inflated. The stent is then left there to help keep the artery open.
