Abstract:
An artificial blood vessel is composed of a cylindrical multiple-woven fabric structure allowing only a small amount of blood leakage and can achieve both antithrombogenicity and cellular affinity. The artificial blood vessel includes a cylindrical fabric structure in which a cylindrical fabric whose inside contacts blood is arranged, wherein the cylindrical fabric is a fabric prepared by interlacing a plurality of warp yarns and a plurality of weft yarns with each other into a cylindrical shape; the warp yarns and the weft yarns constituting the cylindrical fabric include a multifilament yarn having a single yarn fineness of not more than 0.50 dtex, and are bound to an antithrombogenic material; the antithrombogenic material forms an antithrombogenic material layer having a thickness of 1 to 600 nm inside the cylindrical fabric; and the water permeability under conditions where a pressure of 16 kPa is applied to the inner surface is less than 300 mL/cm2/min.
