ABSTRACT:
A low priming volume integrated centrifugal pump and membrane oxygenator comprising a housing containing a mass transfer bed comprising gas permeable hollow membrane fibers placed circumferentially in a ring around an impeller. The mass transfer bed is formed by a multiple wrap of a fiber ribbon comprising at least two layers of fibers bonded in precise orientation with fibers in alternate layers are positioned in line with the opening between fibers in the layers above and below. Adhesion means ensure precise orientation of the fibers. Priming volume is further reduced by a small impeller flow channel volume.
