About Acute Ischemic Stroke

Stroke is the third leading cause of death in the developed world and the leading cause of serious long-term disability. Ischemic stroke represents over 85% of strokes and occurs when a blockage or clot develops in one of the arteries supplying blood to the brain. In 2004 the FDA cleared Concentric Medical's Merci Retriever(R) for use in patients who are ineligible for IV-tPA or who fail to respond to IV-tPA therapy. This pioneering device created a departure from the historic method of caring for stroke patients and offered physicians and patients a long-awaited option for stroke intervention.
