ABSTRACT:
A combination heat exchanger and oxygenator device is provided. The device includes a generally cylindrical housing having first and second compartments with hollow heat exchange tubes and hollow gas exchange tubes disposed therein, a blood inlet, a blood outlet, a heat exchanges medium inlet, a heat exchange medium outlet, an oxygenating fluid inlet and an oxygenating fluid outlet. The housing has a central axis with the second compartment being concentric thereto. The blood flow passage is defined by blood entering the device generally axially through a path extending along the central axis of the housing and flows generally radially through the second, oxygenating compartment.
