ABSTRACT:
A dynamic blood pump includes a rotating core member and rotating ring portion effective to pre-spin blood before the blood enteres helical pumping channels of the pump. The blood is pumped and further rotated as it moves axially along the helical channels toward a centrifugal section of the pump. At the centrifugal pumping section circumferential velocity differentials are also controlled to diminish damage to the blood. Outwardly of the centrifugal pumping section, a forced-vortex pumping section communicates the pumped blood to an exit port.
