MEDICAL SYSTEM

A medical system including a body; a first electrode; a second electrode; an electric generator; and a processing device suitable for determining an electrical characteristic that represents the capacity of the tissue of an anatomical structure between first and second contact surfaces of the first and second electrodes to conduct the electric current, and for emitting a warning signal corresponding to the determined electrical characteristic, the warning signal being intermittent. The processing device is suitable for detecting a variation in the electrical characteristic and for varying at least one variable parameter of the warning signal after a time delay, in accordance with the variation in the electrical characteristic, has elapsed.
