Stent

Last crawled date: 2 years ago

A stent is a tiny tube placed into a hollow structure in your body. This structure can be an artery, a vein, or another structure such as the tube that carries urine (ureter). The stent holds the structure open.

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.

A coronary artery stent is a small, self-expanding, metal mesh tube. It is placed inside a coronary artery after balloon angioplasty. This stent prevents the artery from re-closing.

A drug-eluting stent is coated with a medicine. This medicine helps further prevent the arteries from re-closing. Like other coronary artery stents, it is left permanently in the artery.
