Abstract

A device having a blood oxygenator and heat exchanger of the outside perfusion type. The blood oxygenator employs a tightly packed, crisscrossing bundle of gas permeable hollow fibers. The heat exchanger employs a bundle of polyurethane, liquid impermeable hollow tubes. A center divider facilitates two separate compartments and allows control over pack densities within each compartment while allowing blood to move in a planar manner throughout the device.
