The invention relates to a rotary piston pump, in particular for pumping blood, comprising a piston rotor () which has particularly two or three faces when seen in cross-section, which is mounted in a piston chamber () and eccentrically rotates, the piston rotor () having in its interior a plurality of magnetically interacting elements (), in particular permanent magnets and/or coils, and being driven by the magnetic interaction of these elements () with at least one moving magnetic field.

Rotary-piston pump

An axial-flow blood pump has a rotatable impeller assembly rotatable about an axis and itself having a radially projecting blade and permanent magnets, A stationary stator assembly has stator windings interacting with the permanent magnets and a bearing system supporting the rotatable impeller assembly for rotation about the axis relative to the stator assembly. A stent implantable into a blood vessel is connected to ends of supports for coaxially mounting the stator assembly carrying the impeller assembly in the stent.
