An arterio-venous graft includes an implantable tubular member and a flow regulator. The implantable tubular member has a first end and a second end generally opposite the first end. The flow regulator is between the first end and the second end. The flow regulator is configured to regulate fluid flow between the first end and the second end. A method of regulating pressure in an arterio-venous graft includes reversibly adjusting a cross-sectional area of the graft. A method of fluidly coupling an artery and a vein includes connecting a first end of an implantable tubular member to the artery and connecting a second end of the implantable tubular member to the vein. A cross-sectional area of the implantable tubular member is reversibly adjustable.
