The study enrolled patients who had a stroke caused by an intracranial lesion and for whom medical treatment failed to prevent another stroke. ICAD was an independent determinant of vascular improvement (odds ratio, 7.94 95 confidence interval, 3.32-19.01). The FDA granted Humanitarian Device Exemption (HDE) status in August 2005 to Wingspan based on a multi-center study in Europe and Asia. Multiple studies have evaluated the significance of ICAD as a cause of acute and recurrent stroke,68 but few studies have investigated its importance in patients with acute ischemic stroke (AIS) receiving. It is the only device of its kind available in the U.S. Atherosclerotic intracranial arterial disease (ICAD) is one of the most common causes of stroke worldwide1, 2, 35 and is associated with a high risk of recurrent stroke. The device, called the Wingspan Stent System with Gateway PTA Balloon Catheter, is manufactured by Boston Scientific of Natick, Mass. About 10 percent of stokes are due to problems associated with ICAD. "Without any intervention, these patients have a significant chance of having another stroke within a year."Īccording to the American Stroke Association, there are about 700,000 strokes cases every year. Riina, associate professor of neurological surgery at Weill Medical College of Cornell University and co-director of the division of interventional neuroradiology at NewYork-Presbyterian/Weill Cornell. "Recent research has shown that a very large percentage of patients with plaque buildup in their brains' vessels do not respond to medication," says Dr. "As opposed to carotid stents that are made of stainless steel, this brain stent is designed specifically for the fragile vessels of the brain." Pierre Gobin, professor of radiology and neurological surgery at Weill Medical College of Cornell University and director of the division of interventional neuroradiology at NewYork-Presbyterian/Weill Cornell. Now they are being used in a similar fashion inside the brain," says Dr. "Stents, which are thin, wire-mesh tubes, have long been used to successfully open the carotid arteries in the neck to prevent stroke.

A balloon is then expanded to crack the plaque and withdrawn, and the stent is inserted and deployed to open the vessel. The device is threaded through the patient's vessels to the location of plaque in the cerebral vessel. The intracranial stenting procedure involves making a small incision in the patient's femoral artery. The Wingspan Stent System is used for those individuals diagnosed with intracranial atherosclerotic disease (ICAD) - excess plaque buildup in the brain arteries. Surgeons at NewYork-Presbyterian Hospital/Weill Cornell Medical Center are the first in the New York City metropolitan area to successfully implant into the brain arteries a new stent specifically designed to treat high-risk stroke patients who have not previously responded to medical therapy.
