1. A method of treating a lesion in an artery of a patient, comprising:
forming an arterial access location in a common carotid artery;
positioning at least a portion of the arterial access device into the common carotid artery via the arterial access location;
causing blood to flow from the carotid artery to a return location via the arterial access device and a shunt connected to the arterial access device by at least one of:
(1) actively pumping blood from the carotid artery to the return location via the arterial access device and the shunt connected to the arterial access device; and
(2) occluding blood flow in at least a portion of the carotid artery to form a pressure gradient that establishes retrograde blood flow through the carotid artery such that blood flows into the arterial access device and the 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.
