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.

Claim (Index 48):
A system of devices for performing a medical procedure at a treatment site in a cerebral vessel of a patient, the system comprising:\n a catheter having a distal end and a catheter lumen having an inner diameter at the distal end; and an inner member sized to slide coaxially within the catheter lumen, the inner member comprising:\n a single lumen; \n a distal-most end having a distal opening from the single lumen; \n a distal tapered portion comprising a first outer diameter that tapers distally to a second outer diameter that is smaller than the first outer diameter; and \n a flexible tubular extension extending distally from the second outer diameter of the distal tapered portion to the distal-most end, wherein a length of the tubular extension has a uniform outer diameter; and \n a stent retriever located within the single lumen of the inner member.
