摘要

An arteriovenous dialysis access graft configured to be implanted in a subject includes: at least one flexible conduit having first and second end portions; and at least one cannulation chamber positioned between the first end portion and the second end portion of the at least one conduit. The chamber includes: an elongated housing having an inlet at a first end thereof and an outlet at a second, opposed end thereof, a posterior wall, a pair of sidewalls, and an open anterior portion defining a cannulation port, wherein the cannulation port has a length that spans at least a major portion of a length of the housing; a self-sealing material extending across the cannulation port; and a longitudinal passageway defined by the housing and the self-sealing material that extends from the inlet to the outlet of the housing.
