A stent is a small metal mesh tube device that is placed in an artery. Stent implantation usually follows angioplasty.

The stent is placed in the newly-opened artery and pressed into the artery wall. It acts as a scaffold to help keep the artery open and will remain in place permanently.

Stent implants are widely used to hold open previously blocked arteries. At Inova Heart and Vascular Institute, we offer patients the latest in stent technology: drug-eluting stents. These stents contain drugs to prevent the scarring that can cause an artery to reclose. Drug-eluting stents spare about 25 percent of our patients from restenosis, which is when a blood vessel becomes re-narrowed and blood flow is again restricted.
