ABSTRACT:
A conductor embedded in the insulating layers of an implantable lead is connected to an electrode by arranging the conductor to be included as one pole in a high voltage circuit having another pole in the form of a needle or the like placed in the vicinity of the conductor. The voltage is increased until an insulating layer-puncturing flash-over between the conductor and the needle takes place. The flash-over arc is maintained to burn a hole in the insulation layers so that the conductor is exposed. The conductor can then be removed out with a curved tool to form a connecting end to be applied to the electrode, or a supplementary conductor can be attached to the exposed conductor for attachment to the electrode.
