ABSTRACT:
The present invention provides an implantable modular AV shunt device, which is capable of monitoring and reporting its own patency, and which comprises a plurality of modular components that may be assembled and adjusted by the vascular surgeon during the implantation procedure, using well-known surgical techniques, in order to provide a custom fit and arrangement for the particular patient involved. The device comprises an arterial anastomotic valve that permits blood flowing through an artery to pass into the shunt device, a venous anastomotic valve that permits blood flowing through the shunt device to pass into a vein, a medial flow control unit, a first flexible shunt that carries blood from the arterial anastomotic valve to the medial flow control unit, a second flexible shunt that carries blood from the medial flow control unit to the venous anastomotic valve, and a valve control system. The valve control system is operable to control both the rate at which blood is permitted to enter the shunt device via the arterial anastomotic valve, as well as the rate at which blood is permitted to exit the shunt device via the venous anastomotic valve.
