Patent Number: US6106776A

Abstract

A blood membrane oxygenator has a housing defining a blood flow path, a rotor hub in the form of a double lumen shaft, and a plurality of distributor disks each having a plurality of hollow fibers which extend across the housing blood flow path. The plurality of distributor disks rotate within the housing to mix the blood resulting in three-dimensional mixing, disruption of the blood boundary layer and efficient blood oxygenation.
