  1. Coronary stents are now used in nearly all angioplasty procedures. A stent is a tiny, expandable metal mesh coil. It is put into the newly opened area of the artery to help keep the artery from narrowing or closing again. Once the stent has been placed, tissue will start to coat the stent like a layer of skin. The stent will be fully lined with.
