Overview
Carotid arteries supply blood to the brain. When they become narrowed by plaque, blood flow to the brain is reduced, resulting in the increase risk of stroke. Stroke is the third leading cause of death in the United States and a major cause of serious long-term disability. The AHA estimates that 20-30 percent of strokes are caused by particles of atherosclerotic plaque, which travel downstream into vessels that supply blood to the brain.
The most common treatment for this condition is removal of the obstructing blockage created by plaque, by the means of surgery. Another less invasive procedure involves inserting a metallic spring-like device called a stent into the artery to keep it from occluding. During this procedure, a small umbrella-like filter is used to capture any particles dislodged during stenting, decreasing the risk of thrombo-embolism.
We performed in vitro flow motion analysis of several distal protection filters currently available in the market: Angioguard ™, Accunett™, and FilterWire EX™. A filter will be redesigned based on the results of in vitro testing.
