摘要：
혈관내혈액펌프(P)는임펠러(Impeller, 6)와상기임펠러(6)를구동시키기위한전기모터를포함하는펌핑장치(1)를포함한다. 전기모터의로터(Rotor, 7)는, 상기임펠러(6)의회전을유발할수 있도록, 상기임펠러(6)에결합되고회전축을중심으로회전가능하며, 상기펌핑장치(1) 내의캐비티(22) 내부에배치된다. 상기캐비티(22)는세라믹물질로이루어진내부슬리브(Sleeve, 14)에의해형성된다. 전기모터의스테이터(Stator)의적어도일부, 특히코일와인딩(Coil Winding, 9)은세라믹내부슬리브(14) 상에배열될수 있다.
摘要（英）：
An intravascular blood pump (P) comprises a pumping device (1) including an impeller (6) and an electric motor for driving the impeller (6). A rotor (7) of the electric motor is disposed inside a cavity (22) in the pumping device (1) and rotatable about an axis of rotation and coupled to the impeller (6) so as to be able to cause rotation of the impeller (6). The cavity (22) is formed by an inner sleeve (14) made of a ceramic material. At least a portion of the stator of the electric motor, in particular a coil winding (9), may be arranged on the ceramic inner sleeve (14).
