Abstract:
1. An electrode catheter system for defibrillation or mapping or ablation of cardiac tissue, including an electrode catheter having a terminal at a proximal end of the electrode catheter and one or more sensing or treatment electrodes or both along a distal length on or in proximity to a distal end of the electrode catheter, and having at least one electrical conductor, via which the sensing or treatment electrode is electrically connected to the terminal, wherein the distal length of the electrode catheter is flexible and steerable, with the electrode catheter being more rigid proximally of the distal length, wherein the electrical conductor is made of carbon whereby the electrode catheter is constructed as capable of use in the course of magnetic resonance tomography and further wherein the electrical conductor is adapted for connection to an electrophysiology therapy device and has: a. at least one treatment electrode for delivering high-frequency currents for tissue ablation, and b. a current source connected in communication with the electrical conductor via the terminal, the current source being configured to deliver high-frequency ablating currents to the electrode.
