METHOD OF MANUFACTURING A BLOOD PUMP

Abstract

An intravascular blood pump comprises a pumping device including an impeller and an electric motor for driving the impeller. A rotor of the electric motor is rotatable about an axis of rotation and coupled to the impeller so as to be able to cause rotation of the impeller. An outer sleeve forms a casing of the pumping device, wherein stator components are fixed inside the outer sleeve by means of a casting compound. In a method of manufacturing the blood pump the stator components are placed on a molding base, including the outer sleeve to thereby form an interspace between the molding base and the outer sleeve in which the stator components are disposed. The casting compound is then injected into the interspace via the molding base to fix the stator components inside the outer sleeve. The outer sleeve preferably comprises a magnetically conductive material to form a yoke of the electric motor.
