(57) Abstract :
A rotary blood pump includes a casing defining a pumping chamber. The pumping chamber has a blood inlet and a tangential blood
outlet. One or more motor stators are provided outside of the pumping chamber. A rotatable impeller is within the pumping chamber
and is adapted to cause blood entering the pumping chamber to move to the' blood outlet. The impeller has one or more magnetic
regions. The impeller is radially constrained in rotation by magnetic coupling to one or more motor stators and is axially constrained
in rotation by one or more hydrodynamic thrust bearing surfaces on the impeller.
