Coronary artery stent

Coronary artery stent

Overview

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 incision can be made in the groin area to reach the artery there. A catheter is guided through the groin artery into an area of the coronary artery which 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.
