Rush studies new device for removing blood clots from the brain
Clot-busting drugs can help people with strokes, but they work best if given within three hours after symptoms start.
Now, however, Rush University Medical Center in Chicago is testing a new treatment that could widen that narrow window of opportunity.
The Penumbra stroke system can be used up to eight hours following a stroke and uses a catheter to suction blood clots from the brain, says Demetrius Lopes, MD, neuroendovascular surgeon at Rush.
The catheter is placed into the body through a small incision in the groin and is maneuvered through the blood vessels, using x-ray guidance, until it reaches the site of the clot. Once it’s in the correct spot, a separator device is released from the catheter to dislodge the clot, which the suction device then grabs and pulls back into the catheter.
Researchers believe the system may be a good option for removing clots that can’t easily be grasped or pierced by other devices. It also may be less likely to injure the blood vessel wall.
Rush is participating in a research study to evaluate the safety and effectiveness of the Penumbra stroke system. For more information, on the study visit the clinical trials area of our Web site Investigational Device for Removing Blood Clots from the Brain.
