Background: Ventricular assist devices are lifesaving for patients with end-stage heart failure who have no other options to survive until heart transplantation.The majority of new-generation devices are fully implantable blood pumps with axial or centrifugal flow directions.Current axial-flow blood pumps contain a conveying spiral for blood transport with a central rotating body and have very suitable dimensions for implantation.
