Surgery Faculty Patents
A blood oxygenator includes an integral pneumatic pump disposed substantially within a housing thereof, an inlet blood flow redirector, and an outflow blood collector. An atrium provided at an inlet of the oxygenator promotes even delivery of blood to the oxygenator. In use, the oxygenator provides an even dispersion of blood therethrough, establishing even perfusion and reducing areas of stagnant blood flow.
Axial-Centrifugal Flow Catheter Pump For Cavopulmonary Assistance, Dongfang Wang, Joseph B. Zwischenberger
Axial-Centrifugal Flow Catheter Pump For Cavopulmonary Assistance, Dongfang Wang, Joseph B. Zwischenberger
Surgery Faculty Patents
An axial-centrifugal flow catheter pump for cavopulmonary assistance is provided, incorporating a rotor providing both an axial fluid flow and a centrifugal fluid flow. The rotor includes a first terminal impeller configured to provide a centrifugal and axial fluid flow in a first direction, a second terminal impeller configured to provide a centrifugal and axial fluid flow in a second direction opposite to the first direction, and a central impeller configured to provide a predominantly centrifugal fluid flow. The first and second terminal impellers each include blade arrangements configured to provide a centrifugal and axial fluid flow directed toward the …
