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 rotor rotatable about an axis of rotation and coupled to the impeller so as to be able to cause rotation of the impeller, the method comprising the steps of:
providing a molding base sized and shaped for receiving stator components thereon;
placing the stator components on the molding base by placing an inner sleeve on the molding base, the inner sleeve forming a cavity for receiving the rotor;
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 inner sleeve and the outer sleeve in which the stator components are disposed; and
injecting a casting compound into the interspace via the molding base to fix the stator components inside the outer sleeve.
