Abstract
A bipolar electrode (1) that can be implanted is provided with at least two poles at its distal end, namely a cathode (4) and an anode (6) spaced apart therefrom. Further, an anchoring is provided at the distal end of the electrode (1), provided for example as a helical screw (5). The different poles are arranged on different shafts or tubes (3) and (7) displaceable in reference to each other, in which the exterior shaft or tube (7) first can be pushed over the anchor (5) in order to protect it during implantation. In the operational state, the poles are adjusted by a relative motion of the two shafts carrying them with regard to their relative positioning.
