1. A method for creating an arteriovenous fistula or an arteriovenous graft in a human patient, the method comprising:
fluidly connecting one end of a pump-conduit assembly to the donating vein or location;
fluidly connecting another end of the pump-conduit assembly to an accepting vein; and,
pumping venous blood from the donating vein or location into the accepting vein, wherein: the pumping of blood results in a mean wall shear stress in the accepting vein of greater than or equal to 0.76 Pa;
the pumping of blood results in a mean pulse pressure in the accepting vein of less than 40 mmHg; and
the pumping of blood results in an increase in the lumen diameter and overall diameter of the accepting vein which persists after pumping has ceased; and,
creating the arteriovenous fistula or arteriovenous graft in the patient using at least a portion of the accepting vein with the persistently-increased lumen diameter and overall diameter.
