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 rotor central impeller. Cavopulmonary assistance devices are provided including the axial-centrifugal flow catheter pump
