摘要：
An arteriovenous dialysis access graft is configured to be implanted in a body of a subject. The arteriovenous dialysis graft comprises a flexible conduit defining a longitudinal flow passageway. The conduit has a first end portion and a second end portion, the first end portion configured to connect to an artery of the subject and the second end portion configured to connect to a vein of the subject such that blood flows through the longitudinal flow passageway of the conduit from the first end portion to the second end portion. The graft further comprises a first cannulation chamber and a spaced second cannulation chamber with the conduit extending through each of the first chamber and the second chamber. The first chamber is positioned between the first end portion and the second chamber, and the second chamber is positioned between the second end portion and the first chamber. A valve device is positioned between the first cannulation chamber and the second cannulation chamber for controlling fluid flow.
