An implanted device such as cochlear implant having electrodes is provided with a pulse generator for generating stimulating pulses. The pulses are adjusted to insure that during the idle periods between the pulses, the voltage on the electrodes is at zero or at a preselected level. In one embodiment, the pulse durations or amplitudes are adjusted. In another embodiment the voltage on the electrodes is measured before and during each pulse to determine IR drops from the electrodes to a reference point, and to compensate for the same.

Cette invention concerne un dispositif implanté du type implant cochléaire pourvu d'électrodes, ledit dispositif comportant un générateur d'impulsions destiné à la génération d'impulsions de stimulation. Ces impulsions sont ajustées de façon à assurer une tension nulle ou de niveau préétabli sur les électrodes au cours des périodes d'inactivité existant entre les impulsions. Selon une réalisation, on ajuste les durées d'impulsions ou leurs amplitudes. Selon une autre réalisation, on mesure la tension au niveau des électrodes, avant et pendant chaque impulsion, de façon à évaluer les chutes ohmiques au niveau des électrodes jusqu'à un point de référence, et de façon à compenser ces chutes.
