Abstract

The ablation catheter (10) is designed as a pipe (12) accommodating a shaft (14) with several electrodes (20) attached to the tips and in the center of holding elements (18) radial arranged at the front of the shaft (14). One electrode is additionally positioned in the center (22) between the radial elements (18). The rear of the shaft (14) is enveloped by a sheath (28). Each of the elements (18) is connected to a longitudinal positioned wire (24) in order to be pulled close to the shaft (14) if required by the particular operation.
