Solitaire™ FR Device Mechanically Removes Blood Clots From Blocked Vessels After StrokePosted on March 2, 2012
Approximately 700,000 people suffer an acute ischemic stroke each year in the U.S. The SWIFT clinical study was the first randomized clinical trial ever conducted on mechanical intervention for acute ischemic stroke. The study randomly assigned 113 stroke patients at 18 hospitals to a procedure to restore blood flow to the brain with either the Solitaire FR device or the Merci Retriever device within eight hours of stroke onset. The Solitaire FR device showed a 2.5x benefit in restoring blood flow to the brain, as determined by a blinded core lab, a 1.7x improvement in post-stroke neurological function and a 55% reduction in mortality at 90 days.
“This study is very important to give us a more effective tool to treat stroke,” said Demetrius Lopes Director of Cerebrovascular Surgery at Rush University Medical Center one of the contributing sites to the SWIFT clinical study.
Stroke is a disease that affects the arteries leading to and within the brain. Ischemic stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is blocked by a clot. According to the American Heart Association, stroke is the fourth leading cause of death in the U.S. and a leading cause of long-term disability.
