Abstract:
1. An integrated blood pump oxygenator or gas transfer device comprising: A central housing member defining a central blood flow path extending along a general longitudinal axis of the integrated blood pump oxygenator or gas transfer device; A center pump housing member coupled to the central housing member and defining a pump inlet in fluid communication with the central blood flow path; An impeller rotationally received within the area of the pump inlet formed by the central pump housing member, wherein the impeller, inlet and center pump housing member combine to form a centrifugal pump; An impeller housing supporting the impeller and wherein the impeller housing and center pump housing member combine to form a rollover outlet in the form of an annular chamber extending around the center pump housing member; An outer housing coupled to the impeller housing; An annular array of hollow fiber membranes configured for gas transfer within the outer housing; and An annular chamber within the annular array of hollow fiber membranes in fluid communication with the annular chamber extending from the impeller around the center pump housing; wherein the annular chamber provides substantially perpendicular radial outward cross flow across the membranes.
