1. A method for treating a carotid artery, comprising:
positioning an arterial access sheath into a common carotid artery via an insertion site in the patient's neck, wherein the arterial access sheath is formed of an elongated body sized and shaped to be introduced into a common carotid artery, the arterial access sheath having an internal lumen that can receive blood flow, and wherein the arterial access sheath is configured to be coupled to an extracorporeal shunt that fluidly communicates with the arterial access sheath, wherein the shunt provides a pathway for blood to flow from the arterial access sheath, and wherein the shunt is coupled to a flow control assembly, wherein the flow control assembly defines two or more parallel flow paths and a valve to open or close one or more of the flow paths to selectively direct blood flow through one or more of the flow paths;
treating an artery via the arterial access sheath.
