Abstract:
1. A bipolar electrode ( 1 ) that can be implanted, comprising two unipolar electrodes, with one including a cathode ( 4 ) located at a distal end of a first shaft or tube ( 3 ), and the other comprising an anode ( 6 ) spaced apart therefrom and located on a second shaft or tube, with the second shaft or tube ( 7 ) encasing the first shaft or tube ( 3 ) provided with the cathode ( 4 ) and being displaceable or shiftable in reference thereto in an axial direction, the cathode, which includes an electrode provided with at least one anchor ( 5 ) at the distal end adapted for fastening in the tissue of the heart at least in an operational position of the cathode ( 4 ), and the anode ( 6 ) each are electrically connected to a bipolar plug ( 2 ), the second shaft ( 7 ) accepts and encases the anchor ( 5 ), which comprises a helical screw ( 5 ), during the implantation and the second shaft ( 7 ) provided with the anode ( 6 ) is axially adjustable in reference to the first shaft ( 3 ) at least by a length of the helical screw ( 5 ) in reference to the distal end of the first shaft ( 3 ), and the second shaft ( 7 ) carrying the anode ( 6 ) is provided with a coupling ( 9 ) at its proximal end, which is displaceable and fixable or settable in reference to the first shaft ( 3 ) located therein.
