coronary stents

Coronary stents are small, mesh-like tubes inserted into narrowed or blocked coronary arteries to help keep them open. These arteries supply blood to the heart, and blockages can lead to chest pain or heart attacks. A stent is usually placed during a procedure called angioplasty, where a balloon expands the artery, and the stent is then positioned to support the vessel walls. This helps restore blood flow, reducing symptoms and improving heart health. Stents can be made of metal or coated with medication to prevent future blockages.
