A motor/blood pump which axially pumps blood to a patient connected to a heart/lung machine includes a cylindrical pump housing, a rotor located in the housing, at least one impeller blade attached to the rotor, a pair of stator halves mechanically connectable to the outside of the housing and a motor controller electrically connected to the stator halves. The controller electrically actuates the interconnected stator halves to rotatably drive the rotor on a hydrodynamic bearing of the blood in the housing, and the impeller blade axially pumps blood through the housing. Mechanically and electrically interconnectable stator halves enable the reusable stator to be connected to and disconnected from the disposable pump housing without interrupting the blood flow path. |
