Claim Text:
1. A blood pump, comprising a hollow body, in which an impeller with a blading is provided for an axial propulsion of the blood along the impeller, as well as an at least partly actively stabilised magnetic bearing device for the impeller, wherein the impeller is configured to be set into a rotation about a rotation axis of the impeller with a motor stator located outside the hollow body, and wherein the hollow body includes a hollow cylinder in which the blading is provided, and the hollow body comprises 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, wherein the outlet is arranged offset to the rotation axis of the impeller such that an outflow angle (α) is produced between the inflow direction and the outflow direction, said angle being different from zero, and wherein the blading is designed as a helix, and the blading extends along the impeller up to but not past an outlet-side end of the hollow cylinder that is opposite an inlet-side end of the hollow cylinder.
