Stent

A stent is a tiny tube placed into an artery, blood vessel, or other hollow structure (such as one that carries urine) to hold it open.

Coronary artery stent

When a stent is placed into the body, the procedure is called stenting. There are different kinds of stents. Most are made of a metal or plastic mesh-like material. However, stent grafts are made of fabric. They are used in larger arteries.

  • An intraluminal coronary artery stent is a small metal mesh tube that expands in the artery. It is placed inside a coronary artery after balloon angioplasty to prevent the artery closing again.
  • A drug-eluting stent is a stent that is coated with a medicine that helps prevent the arteries from re-closing. Like other coronary artery stents, it is left in placeĀ in the artery.
