Diagram of an implantable centrifugal-flow pump

A diagram of the fully magnetically levitated centrifugal-flow pump. Blood enters at the central axis of the rotor and is driven outward centrifugally to the outflow of the pump. The pump is considered to be a continuous-flow pump (rather than a pulsatile-flow pump) because blood flow is continuous and not interrupted, although the centrifugal-flow pump incorporates rapid changes in rotor speed to create an intrinsic artificial pulse.
