<p>An implantable heart stimulator comprises a pulse generator for delivering electric stimulation pulses to a patient's heart through a lead (14), connectable to said pulse generator, possibly through a connector top (12) on a pulse generator housing (10). The pulse generator housing is electrically conductive. In an infection control apparatus for such a heart stimulator the exterior surfaces of the possible connector top (12) and of a proximal part (16) of the lead (14) are electrically conductive. The proximal part extends to a position, which after implantation of the lead is situated between a location beyond the entry into the venous system and the entry to vena cava superior. The generator housing (10) and the electrical conductive surfaces of the proximal lead part and of the possible connector top are adapted to form at last two separate electrodes and a current source is provided to supply an electric infection control current between these electrodes.</p> |
