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.

An apparatus for endobronchial ablation of a tumor is provided. The apparatus has an ablation catheter and a guide facility to be inserted into the bronchial system, a sheath defining a guide channel for the ablation catheter, a closing apparatus for a bronchial arm, and an aperture allowing airtight insertion of the ablation catheter into a bronchial arm blocked by the closing apparatus. The ablation catheter and/or the guide facility have a suction apparatus for sucking air out of a bronchial arm blocked off by the closing apparatus.
