Axial flow blood pumps are widely used for mechanical circulatory support including implantable left ventricular assist device and peripheral intra-aortic ventricular assist device. The miniaturization of the devices plays more and more important role in extending the treatable therapeutic options using these blood pumps. On the other hand, miniaturization will be accompanied with higher motor speed and lower energy efficiency, and blood compatibility of the devices must be taken special care in their developmental stage.
