Abstract
A hollow fiber oxygenator including a hollow fiber bundle having first and second ends located within an oxygenator chamber. The oxygenator chamber includes a hollow core around which the hollow fibers are spirally wound and includes an outer casing adjacent the fibers. A gas entry port is coupled to the interior of the fibers adjacent the first end of the bundle and a gas outlet is coupled to the interior of the fibers at the second end of the bundle. A blood inlet to the oxygenator chamber, exterior of the fibers, is provided adjacent the second end of the bundle, and a blood outlet from the oxygenator chamber is provided adjacent the first end of the bundle. The resulting structure provides an axial flow oxygenator, in which the direction of blood flow through the oxygenator chamber is opposite the direction of gas flow through the fibers.
