An integrated blood pump, oxygenator and heat exchanger is provided having a rotating hollow fiber bundle assembly. A plurality of vanes arranged along a central shaft of the device increase pressure near the center of the fiber bundle to develop sufficient pressure head to pump the blood through the heat exchanger. In alternative embodiments, the heat exchanger comprises a pleated metal wall, a bundle of non-permeable hollow fibers, or a coiled tub disposed between the rotating hollow fiber bundle and an interior wall of the housing.

1. A system for processing blood comprising:a housing having an interior wall, a gas inlet, a gas outlet, a blood inlet, a blood outlet, a coolant inlet and a coolant outlet; a shaft disposed within the housing; an annular bundle of hollow fibers disposed for rotation on the shaft, the annular bundle having a first end in fluid communication with the gas inlet, a second end in fluid communication with the gas outlet, and a central void in fluid communication with the blood inlet; a plurality of vanes disposed within the central void and affixed to the shaft; and a heat exchanger element having an exterior surface disposed within the housing between the annular bundle and the interior wall of the housing, an interior of the heat exchanger element in fluid communication with the coolant inlet and the coolant outlet, wherein rotation of the annular bundle causes blood received within the central void to pass outward through the annular bundle, flow around the exterior surface of the heat exchanger element, and exit through the blood outlet.
