Abstract

A blood pump includes a hollow body in which an impeller with blading is provided for producing an axial propulsion of blood along the impeller. An at least partly actively stabilized magnetic bearing device is provided wherein the impeller may be set into a rotation about a rotation axis of the impeller, with a motor stator. The hollow body has an inlet for the flow of blood into the hollow body in an inflow direction which is essentially parallel to the rotation axis, and an outlet for the outflow of the blood out of the hollow body in an outflow direction.
