Angioplasty implants, also known as stents, are medical devices used to treat narrowed or blocked arteries. They are inserted into the artery to help keep it open and improve blood flow. Stents are usually made of metal mesh and are placed in the artery during an angioplasty procedure. They can also be used to treat other conditions such as aneurysms. Angioplasty implants are a common treatment for cardiovascular diseases and can help reduce the risk of heart attack and stroke.
