Abstract
An intravenous oxygenator having hollow, gas-permeable fibers extending between a distal manifold and a proximal manifold that permit diffusion of gases between the blood vessel and interior of the fibers A rotatable support member extends through the proximal manifold and into the distal manifold. The support member has a lumen in communication with the distal manifold so that oxygen-containing gases flow through the support member, distal manifold, fibers, and proximal manifold. An impeller is attached to and rotated by the support member to enhance blood flow around the fibers.
