Stent


Stent in Left Coronary Artery : The heart shown in this image has had a stent placed in the left coronary artery. Stents are tiny coils of wire mesh used to open up blocked arteries in a medical procedure called an angioplasty. They are often inserted laparoscopically, feeding wires up to the coronary arteries through arteries elsewhere in the body that are more accessible, without having to open the patient's chest. Stents are specially engineered to fit various diameters of arteries, allowing an individualized fit. Once in place, the previously blocked artery is now equipped with a miniature scaffolding to hold it open and allow blood to easily flow through.

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.
