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 medicine, a stent is a tube or other device placed in the body to create a passage between two hollow spaces, and stenting is the placement of a stent. There is a wide variety of stents used for different purposes, from expandable coronary, vascular and biliary stents, to simple plastic stents used to allow the flow of urine between kidney and bladder. Stent is also used as a verb to describe the placement of such a device, particularly when a disease such as atherosclerosis has pathologically narrowed a structure such as an artery.
