Patent ID: 8588940

Claim:
Device ( 1 ) for defibrillation of a heart ( 2 ) comprising an implantable cardiac pacemaker and defibrillator ( 3 ), at least one defibrillation electrode ( 4 ) and associated counter electrode, at least one implantable stimulation electrode ( 5 ), the defibrillation electrode ( 4 ) is connected in a position of use to the stimulation electrode ( 5 ) such that a pole ( 6 ) of the defibrillation electrode ( 4 ) is arranged on an outside of the stimulation electrode ( 5 ), and the defibrillation electrode is moveable relative to the stimulation electrode ( 5 ) and is retractable from the position of use and is adapted to be exchangeable relative to the stimulation electrode ( 5 ) that remains implanted in the position of use, wherein the pole ( 6 ) of the defibrillation electrode ( 4 ) is constructed as an electrically conductive coil arranged on a mount that is moveable relative to the stimulation electrode ( 5 ), with which the coil forming the defibrillation electrode ( 4 ) or the pole ( 6 ) is adapted to be retracted and exchanged, and the mount for the defibrillation electrode is an inner tube ( 8 ) that is arranged so that it is moveable on the stimulation electrode ( 5 ) in the position of use.
