Heart disease guide Stent: This is a small tube that acts as a scaffold to support the inside your coronary artery. A balloon catheter, placed over a guide wire, puts the stent into your narrowed coronary artery. Once in place, the balloon is inflated, and the stent expands to the size of the artery and holds it open. The balloon is then deflated and removed while the stent stays in place. Over several weeks, your artery heals around the stent. These are often placed during angioplasty to help keep the coronary artery open. The stent is usually made of metal and is permanent. It can also be made of a material that the body absorbs over time. Some stents contain medicine and are designed to reduce the risk of the artery getting blocked again (your doctor may call that restenosis).

Drug-Eluting Stents - Topic Overview Stents are small, expandable tubes that are inserted during angioplasty into a narrowed or blocked section of the coronary artery to open the artery and improve blood flow. See a picture of a stent. Drug-eluting stents are used more often than bare-metal stents.

Bioresorbable stent Bioresorbable stent. In medicine, a stent is any device which is inserted into a blood vessel or other internal duct in order to expand the vessel to prevent or alleviate a blockage. Traditionally, such devices are fabricated from metal mesh and remain in the body permanently or until removed through further surgical intervention.

Angioplasty The catheter is fed up to coronary arteries to an area of blockage (B). A dye is released, allowing visualization of the blockage (C). A stent is placed on the balloon-tipped catheter. The balloon is inflated, opening the artery (D). The stent holds the artery open after the catheter is removed (E).

- Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called percutaneous coronary intervention (PCI), also known as coronary angioplasty. PCI restores blood flow through narrow or blocked arteries. A stent helps support the inner wall of the artery in the months or years after PCI. Doctors also may place stents in weak arteries to improve blood flow and help prevent the arteries from bursting. Stents usually are made of metal mesh, but sometimes they're made of fabric. Fabric stents, also called stent grafts, are used in larger arteries.

Balloon Angioplasty and Stents A stent is a small, mesh-like device made of metal. When a stent is placed inside of a coronary artery, it acts as a support or scaffold, keeping the vessel open. By keeping the vessel open, the stent helps to improve blood flow to the heart muscle and reduce the pain of angina.

Coronary stenting Coronary stenting. Definition. A coronary stent is an artificial support device placed in the coronary artery to keep the vessel open after treatment for coronary artery disease. Also called atherosclerosis, coronary artery disease is a build-up of fatty matter and debris on the walls of the arteries.

Stent In medicine, a stent is a metal or plastic tube inserted into the lumen of an anatomic vessel or duct to keep the passageway open, and stenting is the placement of a stent. There is a wide variety of stents used for different purposes, from expandable coronary, vascular and biliary stents, to simple plastic stents used to allow the flow of urine between kidney and bladder. Stent is also used as a verb to describe the placement of such a device, particularly when a disease such as atherosclerosis

- Drug-eluting stents are small scaffolds made of wire that are inserted into the narrowed coronary arteries of patients with atherosclerosis. The stent helps to hold the artery open and also releases a drug that prevents any further blockage or obstruction occurring in the artery.istory and approval of drug-eluting stents. Before drug-eluting stents were available, bare metal stents that did not contain any drugs were used to open up arteries. However, several clinical trials showed that drug-eluting stents were superior to bare-metal stents in preventing coronary artery narrowing.

- Endovascular stents manufactured from superelastic Nitinol represent a major component in the fight against heart disease. However, accurate characterization of the stress/strain distributions in such stents, which govern their deformation and fracture behavior, is essential for their prolonged safe use in human arteries.

Medical Dictionary Stent: A tube designed to be inserted into a vessel or passageway to keep it open. Stents are inserted into narrowed coronary arteries to help keep them open after balloon angioplasty. The stent then allows the normal flow of blood and oxygen to the heart.

Stent: Why and How They Are Used A stent is a tiny tube that your doctor can insert into a blocked passageway to keep it open. The stent restores the flow of blood or other fluids, depending on where it’s placed. Stents are made of either metal or plastic. Stent grafts are larger stents used for larger arteries. They may be made of a specialized fabric. Stents can also be coated with medication to help keep a blocked artery from closing.

Urethral Stent Placement WHAT YOU SHOULD KNOW: Urethral stent placement is a procedure to open a blockage or stricture (narrowing) in your urethra with a stent. The urethra is the tube that carries urine from your bladder out of your body. A stent is a small plastic or metal tube that is used to open your narrowed urethra. Blockages and strictures can make it hard for urine to flow out of your body. Pelvic (hip) injuries and repeat urinary tract infections may lead to urethral strictures and blockages.

Overview Overview. The Freestyle ® Bioprosthesis is a tissue valve obtained from the heart of a pig. A pig's heart anatomy is similar to that of a human heart. The Freestyle heart valve is made without a frame (stent). This allows the valve to move and work like a natural valve.

What Is Angina? For the Coronary Arteries. Doctors may use stents to treat coronary heart disease (CHD). CHD is a disease in which a waxy substance called plaque builds up inside the coronary arteries. These arteries supply your heart muscle with oxygen-rich blood. When plaque builds up in the arteries, the condition is called atherosclerosis. Plaque narrows the coronary arteries, reducing the flow of oxygen-rich blood to your heart. This can lead to chest pain or discomfort called angina.

- Video not loaded. Drug-eluting stents are metal stents that have been coated with a pharmacologic agent (drug) that is known to suppress restenosis: the reblocking or closing up of an artery after angioplasty due to excess tissue growth inside or at the edge of the stent.estenosis has a number of causes; it is a very complex process and the solution to its prevention is equally complex. Traditional bare-metal stents have restenosis rates of up to 25%; current 2nd and 3rd generation drug-eluting stents have reduced that rate to single digits.
