Heart pump device and operating method for a heart pump device

A heart pump device comprising:

• an implantable heart pump;
• a line comprising a plurality of wires, the wires including a first wire and a second wire;
• and
• a controller for controlling the heart pump;
• wherein the controller and the heart pump are connected by the line, and the controller is configured to supply the heart pump with electrical power through the first wire, wherein the first wire is configured to pass through a skin surface;
• wherein the controller and the heart pump each comprise a coupling interface, wherein the coupling interface of the controller and the coupling interface of the heart pump are each configured to communicate electrical signals for data transmission through the first wire between the controller and the heart pump;
• and
• wherein the heart pump comprises a location modulator, wherein the location modulator is configured to receive a carrier signal and data and, depending on this data, the location modulator is configured to implement a switchover between an in-coupling of the carrier signal via the coupling interface of the heart pump into the first wire and an in-coupling of the carrier signal via the coupling interface of the heart pump into the second wire of the line.
