摘要： The present application relates to an implantable blood pump for assisting a heart function. The blood pump comprises a heat source and a wall that delimits a flow cannel. In addition, the blood pump comprises a heat distributor for distributing heat generated by the heat source to a surface of the wall. In order to transfer heat from the heat source to the blood conveyed in the flow channel, the heat distributor is thermally conductively connected to the heat source and thermally conductively connected to the opposite face of the wall from the flow channel.

摘要： A method is provided for producing a bearing arrangement for an implantable blood pump. A bearing arrangement and an implantable blood pump are also provided. In the method, a rotor may be provided having one or more drive magnets. The rotor has a conveying element. In addition, a stator having stator windings is provided. Furthermore, the rotor is arranged in a flow channel formed by an inside wall of the stator. A rotor rotation is then driven. While the rotor rotation is driven, a deflection of the rotor is determined. In addition, the deflection of the rotor may be corrected by applying, removing, magnetizing and/or demagnetizing magnetically active material on the stator and/or on the rotor in a non-rotationally symmetrical manner.
