The entire electronics of a control system and of implantable passive and active medical implants connected to or cooperating with the control system are integrated in a central control unit (ZSE) which, by way of detachable cables or by telemetry or radio contact, controls and monitors all of the implants that are present and, if appropriate, implants that are fitted subsequently in the patient (2). The central control unit is powered by an exchangeable battery. An implant can be switched on or switched off as and when necessary.
