Systems and methods for delivering a miniaturized blood pump configured to draw partially desaturated blood via the femoral vein from the inferior or superior vena cava. A cannula connected to the pump exits the femoral vein and is connected to the femoral artery with a cannula or vascular graft. The pump receives power from a percutaneous lead which runs parallel to the flexible cannula and then exits via a percutaneous opening in the skin. The pump in the venous system removes venous blood and pumps it into the femoral artery. In so doing pressure in the aorta is increased and back pressure in the venous system is decreased.
