Abstract
A membrane oxygenator designed to provide blood flow evenly across a gas permeable membrane in a direction substantially perpendicular to the longitudinal direction of the gas permeable membrane. In particular, the present invention is directed to a membrane oxygenator wherein the blood is distributed substantially evenly and at a substantially constant velocity, in a cross-wise direction across the gas permeable membrane. In accordance with a preferred embodiment, the membrane is a bundle of gas permeable hollow fibers with the blood being distributed in a direction substantially perpendicular to the longitudinal direction of the individual hollow fiber membranes.
