Patent ID: 8002728

Claim:
A system for use in treating a carotid artery, comprising: an arterial access device adapted to be introduced into a common carotid artery, the arterial access device having a 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, the lumen configured for receiving retrograde blood flow through the distal opening from the common carotid artery; a shunt having an internal shunt lumen fluidly connected to the lumen of the arterial access device at a location between the distal and proximal openings of the arterial access device, wherein the internal shunt lumen 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 a flow control mechanism coupled to the shunt and adapted to control blood flow through the shunt.
