Patent ID: 8652084

Claim:
A hemodialytic angioaccess device comprising: an arteriovenous shunt; an arterial anastomotic valve that connects one end of the arteriovenous shunt to an artery; a venous anastomotic valve that connects an opposite end of the arteriovenous shunt to a vein; a valve control system that is operable to independently open and close the arterial and venous anastomotic valves, wherein when the arterial and venous anastomotic valves are open blood flows through the arteriovenous shunt, and wherein when the arterial and venous anastomotic valves are closed blood does not flow through the arteriovenous shunt; and an integrated surveillance system that measures flow conditions in the vein while the venous anastomotic valve is closed, the integrated surveillance system including a venous flow sensor, attached to the venous anastomotic valve to collect data describing the flow conditions in the vein.
