An intraluminal coronary artery stent is a small, self-expanding, stainless steel mesh tube that is placed within a coronary artery to keep the vessel open. It may be used during a coronary artery bypass graft surgery to keep the grafted vessel open, after balloon angioplasty to prevent reclosure of the blood vessel, or during other heart surgeries.
