Abstract:
1. An implantable blood pump comprising: a housing defining an inlet opening and an outlet opening oriented at an angle from the inlet opening; a dividing wall within the housing defining a blood flow conduit for carrying blood, the blood flow conduit extending between the inlet opening and the outlet opening of the housing; and a rotary motor including a stator and a rotor, the stator comprising coils configured to interact with the rotor, the stator being disposed within the housing circumferentially about the dividing wall such that the inner blood flow conduit extends through the stator, the stator being disposed circumferentially about at least a part of the rotor and being positioned relative to the rotor such at least portions of the coils are located upstream of the rotor, the rotor having a rotor axis of rotation and including a rotor magnet for driving the rotor, and the stator including pole pieces that axially overlap with the rotor magnet with respect to the rotor axis of rotation.
