Abstract
An implantable cardioverter defibrillator device comprises a generator device having a processing circuitry and a shock generation circuitry, and at least one lead comprising a shock electrode for emitting an electrical output pulse. The shock generation circuitry comprises an energy supply arrangement containing at least one energy storage device for supplying energy to form an output pulse, an output circuit for outputting said output pulse to the shock electrode, and a current limiting circuit arranged electrically in between the energy supply arrangement and the output circuit such that a current supplied from the energy supply arrangement flows through the current limiting circuit towards the output circuit. The current limiting circuit comprises at least one current limiting component, wherein the current limiting circuit is controllable by the processing circuitry to modulate a current flowing through the current limiting circuit.
