Abstract:
A blood pump () includes a stator assembly including a fluid inlet () and a fluid outlet (). A rotor assembly () includes an impeller () rotatable about an axis () to move fluid from the inlet () to the outlet (). A motor () imparts rotation of the impeller () about the axis (). The motor () includes a motor stator () fixed to the stator assembly (), a motor rotor () fixed to the rotor assembly (), and a radial motor gap () between the stator () and the rotor (). The pump () is configured to direct a mixed blood flow from the fluid inlet () to the fluid outlet () and a wash flow through the motor gap ().
