摘要： A pulse generating implantable medical device comprising a power source for energizing the medical device, a control unit, a plurality of switching units (SW-RC-1, SW-STIM-1, SW-RT-1), a timing unit, a pulse generating unit adapted to generate one or many stimulation pulses to be applied to human or animal tissue via one or many stimulation electrodes, and a coupling capacitor in series with each stimulation electrode. A stimulation pulse is adapted to be applied during a stimulation pulse timing cycle that includes a stimulation phase and a recharge phase, and the timing of a stimulation pulse timing cycle is controlled by said control unit via the timing unit and said switching units. The implantable medical device further comprises an energy storage unit and, during the recharge phase, one or many of the switching units is adapted to establish electrical connection between said one or many stimulation electrodes and said energy storage unit in order to collect and store energy from applied stimulation pulses.

摘要： The invention relates to implantable medical devices, in particular to a implantable heart-stimulation device, a method for operating an implantable heart-stimulation device and a heart-stimulation system, wherein stimulation pulses are delivered via a plurality of stimulation channels to selected sites on or about a patient's heart via electrodes, and wherein coupling capacitors included in the stimulation channels are subsequently discharged through a sequence of temporally non-overlapping partial discharges of the respective coupling capacitors. By this configuration, the risk of charge neutrality of a stimulation channel not being maintained at the end of a stimulation sequence, comprising the delivery of stimulation pulses via stimulation channels, is reduced or eliminated.
