A medical method for providing nutrition to a patient comprises the steps of providing a container having an inlet, an outlet and a pump at the outlet and surgically inserting the container into the abdominal cavity. The container outlet is surgically connected to a selected vein in the portal vein system so that the container communicates with the liver via the container outlet and the selected vein of the portal vein system. The pump is then operated to move a liquid nutritive composition from the container to the selected vein in the portal vein system.
