Claim:
A modular arteriovenous shunt device, comprising: three or more conjoined pieces connected in a series, the three or more conjoined pieces comprising a first flexible shunt, a second flexible shunt, and a medial flow control unit interposed between said first flexible shunt and said second flexible shunt; an arterial anastomotic valve that permits blood flowing through an artery to pass into the three or more conjoined pieces; a venous anastomotic valve that permits blood flowing through the three or more conjoined pieces to pass into a vein; a valve control system to control (i) the rate at which blood is permitted to enter the three or more conjoined pieces via the arterial anastomotic valve, and (ii) the rate at which blood is permitted to exit the three or more conjoined pieces via the venous anastomotic valve; and an integrated surveillance system that automatically generates and stores flow data representing the flow of blood through at least one of said vein and artery.
