Abstract:
1. A system for use in accessing and treating a carotid artery, said system comprising: an arterial access device adapted to be introduced into a common carotid artery and receive blood flow from the common carotid artery, the arterial access device including a distal sheath portion adapted to enter the common carotid artery, wherein the distal sheath portion has a distal region with a reduced luminal diameter to facilitate introduction into the common carotid artery and a proximal region having a larger luminal diameter relative to the distal region to decrease overall flow resistance through the arterial access device; a shunt fluidly connected to the arterial access device, wherein the shunt provides a pathway for blood to flow from the arterial access device to a return site; a flow control assembly coupled to the shunt and adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state, wherein the flow control assembly includes one or more components that interact with the blood flow through the shunt; and a venous return device adapted to output blood flow wherein the venous return device is adapted to be inserted into a vein, and wherein the shunt fluidly connects the arterial access device to the venous return device such that the blood flows through the shunt from the common carotid artery to the vein.
