The invention relates to an inductive disturbance reduction device (18) for reducing an inductive disturbance of a signal like an ultrasound signal to be transmitted via first connection conductors (25, 26) of an electrical connector (11), which is caused when current like ablation current flows through a second connection conductor (24) of the electrical connector. The inductive disturbance reduction device is adapted to induce a voltage, which at least partly compensates a voltage induced in the electrical connector, in order to reduce the inductive disturbance in the signals to be transmitted via the first connection conductors of the electrical connector. Since the inductive disturbance is reduced, a high quality electrical connection can be provided, without necessarily using, for instance, a technically relatively complex and expensive coaxial connector. The inductive disturbance reduction device may be integrated, for instance, in a part of the electrical connector or in a cable.
