A stent is a small wire, mesh tube that’s used to open narrowed arteries in the body.

 

You may have a stent placed in an artery as part of a procedure called angioplasty Angioplasty can restore blood flow through narrowed or blocked arteries. Stents help prevent arteries from becoming narrowed or blocked again in the months or years after treatment with angioplasty. You may also have a stent placed in a weakened artery to improve blood flow and to help prevent the artery from bursting.

 

Stents are usually made of metal mesh, but sometimes they’re made of fabric. Fabric stents, also called stent grafts, are used in larger arteries. Some stents are coated with medicines that are slowly and continuously released into the artery. These medicines help prevent the artery from becoming blocked again.

Coronary Artery Stent Placement

The illustration shows the placement of a stent in a coronary artery with plaque buildup.

The illustration shows the placement of a stent in a coronary artery with plaque buildup. The coronary artery is located on the surface of the heart. Figure A shows the deflated balloon catheter and closed stent inserted into the narrowed coronary artery. The insert image on figure A shows a cross-section of the artery with the inserted balloon catheter and closed stent. In figure B, the balloon is inflated, expanding the stent and compressing the plaque to restore the size of the artery. Figure C shows normal blood flow restored in the stent-widened artery. The insert image on figure C shows a cross-section of the compressed plaque and stent-widened artery.
