摘要： Blood pumps for ventricular assist devices employ a hollow rotor to impel blood through the blood pump. A blood pump includes a housing having a housing inlet, a housing outlet, and a housing blood flow channel through which the housing inlet and the housing outlet are in fluid communication. A motor stator is disposed around the housing blood flow channel and operable to generate a rotating magnetic field. A hollow rotor is disposed within the housing blood flow channel and rotated via the rotating magnetic field. The hollow rotor has a rotor circumferential wall enclosing a rotor blood flow channel. The hollow rotor has at least one rotor blade extending inwardly from the rotor circumferential wall. The at least one rotor blade is configured to impel blood through the rotor blood flow channel when the hollow rotor is rotated via the rotating magnetic field.
