Stent

  • A stent is an artificial 'tube' inserted into a natural passage/conduit in the body to prevent, or counteract, a disease-induced, localized flow constriction.
  • The term may also refer to a tube used to temporarily hold such a natural conduit open to allow access for surgery.
  • The most widely known stent use is in the coronary arteries with a bare-metal stent, a drug-eluting stent or occasionally a covered stent.
  • Coronary stents are placed during a percutaneous coronary intervention procedure, also known as an angioplasty.
