Abstract:
1. An electromedical implant comprising at least a measuring signal generator; an impedance measuring unit to determine the impedance of human or animal tissue; a control unit which, for controlling the measuring signal generator and the impedance measuring unit, is at least indirectly connected to the measuring signal generator and the impedance measuring unit; as well as an electrode arrangement comprising at least two electrodes which can be directly or indirectly connected or at least temporarily connected to the measuring signal generator and to the impedance measuring unit, or to a connection for such an electrode arrangement; wherein: the measuring signal generator is designed to generate and emit first and second current pulses of variable pulse duration; and wherein the control unit is programmed at least at first and second different points in time to cause the measuring signal generator to generate and emit the first current pulse and the second current pulse, so that emission of the first current pulse is finished before emission of the second current pulse starts, and the pulse duration of the emitted first and second current pulses are different; and to cause the impedance measuring unit to measure the voltage that is present between the electrodes connected to the measuring signal generator and the impedance measuring unit
