The catheter (20) has an electrode pole (23) provided in a distal end (24) of a body (21). A supply line (22) e.g. wire or lead, for an electrode pole runs in the body in a main direction (H) from a proximal end (26) to the distal end. A running direction of the line is changed twice such that the line runs opposite to the main direction, and sides (L1, L2) between two direction changes are shorter than half of a specific wavelength of an interfering frequency for desensitizing the catheter against radiation of an electromagnetic field of the frequency having the specific wavelength.
