Stents 101

Coronary Artery Disease

Stents are mainly used to treat coronary artery disease “CAD” (also called atherosclerosis or coronary heart disease). This disease develops when the inner layers of the coronary artery walls become thick and irregular due to deposits of fat, cholesterol and other substances. As the interior walls of coronary arteries become lined with these deposits, they become narrowed, reducing the blood flow through them. CAD is highly prevalent in modern society; tens of millions of people throughout the world have the disease, which makes it the most common type of heart disease.

Treatment of CAD

Each year, many patients with CAD will need treatment to increase the flow of blood to the heart. Interventional cardiology has emerged over the past decade as an alternative to traditional cardiac surgery. Through the use of minimally invasive catheter-based techniques like balloon angioplasty and stent placement in combination with innovative drug therapies, many conditions can now be treated without the need for surgical intervention (most commonly Coronary Artery Bypass Grafting, or CABG) and lengthy hospital stays.

Coronary stents

Coronary stents were designed to overcome some of the short comings of angioplasty. Angioplasty is a technique that is used to dilate an area of arterial blockage with the help of a catheter with an inflatable, small, sausage-shaped balloon at its tip. A coronary stent is a metal tube with slots. It is mounted on a balloon catheter in a "crimped" or collapsed state. When the balloon is inflated, the stent expands or opens up and pushes itself against the inner wall of the coronary artery. This holds the artery open when the balloon is deflated and removed and prevents reblockage of the artery.

Stents are available in different sizes, length and thickness and materials. Every private label manufacturer has it’s own unique stent design, each requiring approval by the FDA, European Notified Bodies and other applicable local authorities before use.

Peripheral stents

Peripheral stents are used to open blockages in arteries in the hip or pelvis, thigh or legs. The procedure is similar to coronary stenting, but can also be done with a self-expanding stent, made of a shape memory material called Nitinol, instead of a balloon-expandable stent.
