Abstract
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.

Implantable blood pump for assisting a heart function, comprising:
- an implantable pump housing;
- a heat source and a wall which delimits a flow channel;
- a heat distributor for distributing heat produced by the heat source to a surface of the wall, the heat distributor, for transferring heat from the heat source to blood conveyed in the flow channel, being connected thermally conductively to the heat source and thermally conductively to a side of the wall orientated away from the flow channel;
- wherein the wall is an inner wall of the pump housing, the pump housing comprises a volute, and the inner wall of the pump housing is an inner wall of the volute;
- wherein the heat source is a stator of a motor, the stator comprising a stator core;
- and
- wherein the heat distributor is configured to transfer heat from the stator to the inner wall of the volute.
