A hollow fiber blood oxygenator (12) is provided having an plurality of enclosed, coaxial heat exchanger coils (16), having a common header (46) to insure uniform temperature in the coils. An enclosed fiber bundle (22) is concentrically positioned inside the heat exchanger coils to define a flow path around the coils and through the fiber bundle. The heat exchanger coils and the outside of the fiber bundle are tapered to provide a close fit. Gas manifolds (32, 40) direct gas flow to and from the hollow fibers. |
