WINGSPAN STENT TO OPEN BLOCKED ARTERIES IN THE BRAIN Wingspan is made by Boston Scientific.
Carotid artery stenting is a procedure in which your vascular surgeon inserts a slender, metal-mesh tube, called a stent, which expands inside your carotid artery to increase blood flow in areas blocked by plaque. The “Wingspan” stent was the first FDA-approved brain stent. The Wingspan stent is intended to open blocked arteries in the brain after clot-dissolving drugs have failed. It is used in patients who have more than 50 percent blockages in a brain artery, and have had a stroke, minor stroke or transient ischemic attack, despite being on blood-thinning medications. The stents that are used around the heart are generally stiffer and harder to navigate around the brain vessels. Heart stents are very difficult to move up the brain anatomy and place into the distal arteries of the head. The Wingspan stent is much softer and is carried on softer catheters that can navigate the brain anatomy better.
