Abstract:
1. A subcutaneous arteriovenous graft system comprising: an arteriovenous graft having an arterial end and an opposite venous end; a first valve device positioned over the arterial end of the arteriovenous graft and a second valve device positioned over the venous end of the arteriovenous graft, wherein each valve device comprises an inner sleeve positioned within an outer sleeve, the inner sleeve including a wall portion having a reduced wall thickness, the wall portion extending along a a discrete area of the inner sleeve positioned adjacent to a fluid passageway defined through the outer sleeve, and a single actuator in flow communication with the fluid passageway defined through the outer sleeve of both the first valve device and the second valve device, the actuator being positioned outside of the arteriovenous graft, the actuator being configured to open and close the valve devices simultaneously, wherein, when fluid is directed through the fluid passageway and against the wall portion, the wall portion inflates inward so as to form a balloon extending within the inner sleeve that restricts the flow of blood through the arteriovenous graft.
