Arteriovenous graft system, arteriovenous valve device and method to implant an arteriovenous graft system

摘要

The invention provides a subcutaneous arteriovenous graft system, comprising an arteriovenous graft having an arterial end, a venous end opposite to the arterial end and an internal volume between the arterial end and the venous end, and a valve device that can be arranged in an open state, in which fluid flow through the graft is possible and a closed state in which the fluid flow through the arteriovenous graft is blocked. The valve device is constructed to decrease, in the closed state of the valve device, the internal volume of the complete graft to substantially zero.
