Minimally Invasive Clot Retrieval Devices

It's a sobering truth — only 3 to 4 percent of ischemic stroke patients can be treated with intravenous (IV) tPA, the standard clot-busting medication. That's because most stroke patients arrive at the hospital after the time window for safely administering tPA has passed.

When this happens, the brain specialists at Medical City Plano employ minimally invasive clot retrieval devices — the Merci Retrieval System® and The Penumbra System®. Used in our neurointerventional biplane angiography suite, these devices can minimize or reverse brain damage in stroke patients.

This catheter-based technology physically removes the clot, clearing the way for blood flow to the brain. It also extends the time window for treatment — up to 12 hours after the onset of stroke symptoms (compared to three to four-and-a-half hours with IV tPA). That translates to lives saved and brain damage prevented.

Neurosurgeons at Medical City Plano have treated stroke patients who have come in completely paralyzed and unable to speak. After extracting the blood clots through our clot retrieval procedure, they were able to walk and talk again.
