Pair of endocardial and epicardial catheters, catheter and method for positioning electrodes on a cardiac wall and method for the ablation of cardiac muscle tissue
The ablation of tissue in a cardiac wall is performed by introducing an endocardial catheter into the interior of a heart and an epicardial catheter is placed on the cardiac wall. With the aid of an electromagnet and a counter-element, which can be permanently magnetized or can also be an electromagnet, the two catheters are mutually attracted in such a way that electrodes come into contact with opposite sides of the cardiac wall such that the electrodes are optimally positioned. The use of a catheter with a plurality of such electrodes in a row enables the removal of whole lines of destroyed cardiac wall tissue by ablation.
