Abstract
A device (10) having a blood oxygenator (12) and heat exchanger (14) of the outside perfusion type. The blood oxygenator (12) employs a tightly packed, crisscrossing bundle of gas permeable hollow fibers (50). The heat exchanger (14) employs a bundle of polyurethane, liquid impermeable hollow tubes (96). A center divider (16) facilitates two separate compartments (30, 40) and allows control over pack densities within each compartment while allowing blood to move in a planar manner throught out the device (10).
