Abstract
A radial flow hollow fiber blood oxygenator is provided. The oxygenator includes a hollow fiber bundle within an oxygenator chamber defined by a hollow core around which the hollow fibers are wound and an outer housing. A gas entry port is coupled to the interior of the fibers adjacent one end of the bundle and a gas outlet is coupled to the interior of the fibers at the opposite end of the bundle. A blood inlet to the core is provided adjacent one end of the bundle, and a blood outlet from the chamber is provided adjacent the same end of the bundle. The direction of blood flow through the chamber is generally radial and the oxygenator includes an inlet manifold and an outlet manifold.
