"(Medical Xpress)\u2014When someone has a stroke, time equals brain. The longer a stroke is left untreated, the more brain tissue is lost. Since the only proven treatment\u2014a clot-busting drug\u2014works in less than half of patients, stroke physicians had high hopes for a mechanical device that could travel through the blocked blood vessel to retrieve or break up the clot, restoring blood flow to the brain."^^<http://www.w3.org/2001/XMLSchema#string>
