Abstract
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.
