摘要： A pumping system for blood for a patient includes a sensorless pump having no sensors disposed in the pump itself for moving the blood, a motor and a blood transport port through which blood is received from the patient and is pumped into the patient. The system also includes a controller connected to the pump for controlling the pump so a desired flow rate of blood can be maintained by the pump.

摘要： A blood pump device comprises a blood pump having blood transport ports, cannulae connected to the ports, and a coating material covering the junction between the inner surfaces of the ports and cannulae. This forms a smooth transition so blood can flow unimpeded therefrom and collection cavities for the blood are eliminated. Also included is a method for producing a smooth coating. The blood pump device comprises a second portion including a stator mechanism, a rotor mechanism, an impeller, a journal, and a seat member. The second portion is constructed to pump blood through the cannulae when power is provided. The blood pump device is also equipped with a safety occluder device, a sensor for detecting back emf in the stator mechanism, and a controller having the capability of indicating stator current and rotor speed.
