Stent in Coronary Artery : In angioplasty with stent placement, the blocked artery is widened by inflating a balloon inside of it. The balloon is removed and a tiny metal coil called a stent is left in place to keep it open.
In the technical vocabulary of medicine, a stent is a mesh '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.
