A pacemaker system for a human subject having bilateral vocal cord paralysis includes a sensing electrode for detecting inspiratory activity of a vocalizing muscle of the subject and generating a first signal, and a processor for receiving the first signal from the sensing electrode and generating a second signal. The second signal is substantially synchronous with the first signal. A stimulating electrode receives the second signal from the pulse generator and stimulating a vocalizing nerve of the subject.

L'invention concerne un système de pacemaker destiné à un sujet souffrant d'une paralysie bilatérale des cordes vocales. Ledit système comprend, d'une part, une électrode de détection servant à détecter l'activité inspiratoire d'un muscle de vocalisation dudit sujet et à générer un premier signal, et, d'autre part, un processeur permettant de recevoir le premier signal émanant de l'électrode de détection et de produire un second signal. Ce signal est pratiquement synchrone au premier signal. Une électrode de stimulation reçoit le second signal provenant du générateur de pulsions et stimule un nerf de vocalisation du sujet.
