Claim 0:
1. A method of treating a lesion in a carotid artery of a patient, comprising:
inserting an arterial access device into an artery through an arterial access location wherein the arterial access sheath comprises a first, expandable occlusion element adapted to occlude the common carotid artery;
positioning at least a portion of the arterial access device into a common carotid artery;
expanding the first occlusion element to occlude the common carotid artery;
actively pumping blood from the common carotid artery to a return location via the arterial access device and a shunt connected to the arterial access device, wherein the arterial access device comprises an elongate member defining an internal lumen that extends from a distal opening at a distal region of the arterial access device to a proximal opening at a proximal region of the arterial access device, wherein the internal lumen receives blood flow through the distal opening from the common carotid artery, and wherein the shunt comprises a shunt lumen connected to the arterial access device at a location between the distal and proximal openings of the arterial access device, and wherein the shunt provides a pathway for blood to flow out of the internal lumen of the arterial access device at a location between the distal and proximal openings of the arterial access device; and
treating the lesion by deploying a stent on the lesion.
