Implantable indifferent reference electrode pole

1. An implantable electrode device designed for heart stimulation and/or cardioversion/defibrillation in connection with a pacemaker or a defibrillator comprising:

a large-surface area indifferent reference electrode pole configured to be permanently implanted in the atrial septum and in electrical communication with a pacemaker or defibrillator, the electrode pole made from biocompatible metal braiding and having a tube like opening,

the electrical communication positioned from the pacemaker/defibrillator through the right atrium of the heart through the indifferent electrode pole into the left atrium through the opening, thus allowing electrical pulses to be delivered to the electrode pole and stimulating the heart.

2. The implantable electrode device according to claim 1 , wherein the electrode pole is shaped like an occlusion element being self-expandable and forming a double disc which bridges the left and right atrium.

3. The implantable electrode device according to claim 1 , wherein the opening of electrode pole has a proximal end and a distal end, the proximal end near the right atrium is attached to an elongated tube.

4. The implantable electrode device according to claim 3 , wherein a stent is placed in the tube like opening.

5. The implantable electrode device according to claim 3 , wherein the tube like opening comprises a seal member disposed within.

6. The implantable electrode device according to claim 5 , wherein the seal member contains a drug formulation.

7. The implantable electrode device according to claim 3 , wherein at least one coil is disposed within an inner part of the elongated tube.

8. The implantable electrode device according to claim 1 , wherein the electrical communication to electrode pole is placed at the outer edge of the metal braiding.

9. The implantable electrode device according to claim 1 , wherein the metal braiding of electrode pole is fitted with a fixation element in form of a screw coil.

10. The implantable electrode device according to claim 1 , wherein the metal braiding of electrode pole is fitted with a fixation element in form of a spread hook fastening element.

11. The implantable electrode device according to claim 1 , wherein at least one part of the metal braiding of electrode pole is coated with a biocompatible polymer layer.

12. The implantable electrode device according to claim 1 , wherein a pacing electrode tip pole is inserted through the opening into the left atrium, the tip pole having a distal screw electrode such that the left atrium is stimulated between the electrode pole and the screw electrode.
