Key Exclusion Criteria

Full Study Name
Perfusion Imaging Selection of Ischemic Stroke Patients for Endovascular Therapy (IRB no. 36183)
The purpose of this study is to assess the safety and effectiveness of the mechanical thrombectomy (physically removing a blockage in a blood vessel) compared to best medical therapy (treatment with the best use of available medicines) in stroke subjects who are able to begin treatment within 12 hours of symptom onset.
The devices used in this study have been approved by the U.S. Food and Drug Administration (FDA) for opening clotted blood vessels in the brain, but researchers will test investigational ways of using these devices. Researchers may also use more than one device in combination, instead of a single device at a time as approved by FDA.
