1. An actuating device for a catheter comprising at least one first part and one second part, which are able to more relative to each other, the actuating device comprising:
- (i) a tubular slide which can be connected to one of said first part and said second part of the catheter;
(ii) a slider, which is mobile with respect to the slide in the direction of a longitudinal axis and which can be actuated for moving said slide and moving said first part and said second part relative to each other; and
(iii) a speed-change mechanism, which is set between said slider and said slide,wherein said speed-change mechanism is able to perform the transmission of the movement between said slider and said slide with at least two drive ratios that are different in successive parts of a movement of said first part and said second part relative to each other.
