Abstract:
1. A device for oxygenating, filtering and controlling the temperature of blood in an extracorporeal circuit comprising a monolithic housing defining first, second and third interior chambers, the first chamber having a substantially cylindrical shape defining a central portion and containing a plurality of microporous hollow fibers and having a blood inlet and a blood outlet connected to the first chamber to define a blood flow path along an exterior of the hollow fibers and having a gas inlet and a gas outlet connected to the first chamber to define a gas flow path through the lumens of the hollow fibers, the second chamber being positioned substantially within the central portion of the first chamber and containing a heat exchange surface and having a blood inlet and a blood outlet connected to the second chamber to define a blood flow path through the second chamber adjacent the heat exchange surface, the blood outlet of the second chamber being connected to the blood inlet of the first chamber, the third chamber containing a filtration membrane and having a blood inlet and a blood outlet connected to the third chamber to define a blood flow path through the filtration membrane, the blood inlet of the third chamber being connected to receive blood from the blood outlet of the first chamber.
