Estimating the term…
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.
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:
An intravascular blood pump for percutaneous insertion into a patient's blood vessel, 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 blood pump further comprising an inner sleeve configured to form a cavity for receiving the rotor and an outer sleeve configured to form at least a portion of an outer surface of the pumping device, wherein stator components are fixed inside the outer sleeve by means of a casting compound.
