ABSTRACT:
A rotary pump having a housing defining a flow path, a stator attached to the housing, a rotor which contacts the stator and rotates thereabout, a motor for rotating the rotor and semiconductor-based electronic components which draws the heat created by the frictional contact between the stator and rotor away from blood flowing through the housing. The rotary pump can be a centrifugal pump having a housing with a base plate, a rotor with rotor blades and a stator wherein the base plate and the rotor are shaped and proportioned such that blood is prevented from stagnating/collecting between the rotor blades and base plate.
