METHODS AND SYSTEMS FOR TREATMENT OF ACUTE ISCHEMIC STROKE

Abstract: described are methods and systems for transcervical access of the cerebral arterial vasculature and treatment of cerebral occlusions, including ischemic stroke. the methods and devices may include methods and devices which may provide aspiration and passive flow reversal, those which protect the cerebral penumbra during the procedure to minimize injury to brain, as well as distal catheters and devices to remove an occlusion. the methods and devices that provide passive flow reversal may also offer to the user a degree of flow control. devices and methods which provide a way to securely close the access site in the carotid artery to avoid the potentially devastating consequences of a transcervical hematoma are also described.
