(HealthDay News) -- A coronary stent is a hollow tube-shaped device that is surgically inserted into a blood vessel to keep it open.

The U.S. National Library of Medicine says a coronary stent may be used to treat the following conditions:

  • Coronary heart disease.
  • Peripheral artery disease.
  • Renal artery stenosis, for a narrowing of the artery that provides blood to the kidneys.
  • Carotid artery disease.
  • Abdominal aortic aneurysm, for a bulging of the aorta near the abdomen.
