A control apparatus for an implantable heart pump is provided, which comprises an implantable first control unit, which is electrically connected to the heart pump in a main operating state for controlling operating parameters of the heart pump. The control apparatus also comprises an interface, which is electrically connected to the first control unit and is intended to wirelessly transcutaneously transmit data and/or to wirelessly transcutaneously transmit energy between the first control unit and a further control unit provided for extracorporeal use. The control apparatus also comprises an implantable second control unit, which is electrically connected to the heart pump in an auxiliary operating state for controlling operating parameters of the heart pump, and an implantable switch, which is electrically connected to the first control unit and the second control unit. The switch is set up to change over between the main operating state and the auxiliary operating state.

At least some embodiments of the disclosure may advantageously limit bleeding and the occurrence of blood leaks after heart pump implantation. In some embodiments, a base may be provided that includes a flexible layer mechanically coupled with a conduit. The flexible layer may be coupled with the proximal end of the conduit. The conduit may be configured to receive a cannula of the heart pump therethrough. The outer surface of the conduit may be configured to engage a surface of the heart formed after coring the heart. The conduit may be metal and may have a flared and/or beveled distal end. The conduit may be a flexible material. A distal flexible layer may be provided at a distal end of the conduit that is configured to engage with an inner surface of the heart.

A blood pump system includes two blood pumps, which may be implanted into a patient. The blood pumps may comprise VAD pumps. Control devices and methods operate the pumps such that they can function as a total artificial heart.

Systems, assemblies, modules, and methods for connecting components of medical devices employ connector cables with electrical conductors.
