Abstract
A compact, cylindrical integrated blood heater/oxygenator in which the blood flows transversely to the axial direction of hollow heat exchange and oxygenation fibers. Blood enters a longitudinally extending central chamber of the blood heater/oxygenator, and moves radially through annular hollow heat exchange and oxygenation fiber bundles in a direction generally perpendicular to the axis of the device and generally transverse to the axial direction of the fibers. The blood proceeds toward the outer wall of the oxygenator where the temperature is adjusted and oxygenated blood is collected and passed out of the oxygenator through an exit port.
