1. A method of manufacturing an intravascular blood pump, the blood pump comprising a pumping device including an impeller and an electric motor for driving the impeller, the electric motor including a stator and a rotor, the method comprising:
providing a molding base;
placing stator components on the molding base, the stator components including a coil winding;
placing an outer sleeve on the molding base to thereby form at least a portion of an outer surface of the blood pump and an interspace between the molding base and the outer sleeve in which the stator components are disposed;
providing at least one sealing ring at a bottom of the coil winding to form a seal at a bottom of the molding base; and
injecting a casting compound into the interspace via the molding base to fix the stator components inside the outer sleeve.
