Abstract

L'INVENTION CONCERNE UN GENERATEUR D'IMPULSIONS D'APPAREIL MEDICAL PRODUISANT DES IMPULSIONS DE STIMULATION. IL COMPORTE UN OSCILLATEUR QUI DELIVRE DES SIGNAUX A UNE FREQUENCE DEFINIE, AVEC UN PREMIER CIRCUIT DE LIMITATION DE FREQUENCE QUI INTERDIT QUE LE SIGNAL DE L'OSCILLATEUR DEPASSE UNE PREMIERE LIMITE SUPERIEURE, ET UN CIRCUIT DE SORTIE COMMANDE PAR LE SIGNAL DE L'OSCILLATEUR DE MANIERE A PRODUIRE DES IMPULSIONS DE STIMULATION, ET COMPRENANT UN SECOND CIRCUIT DE LIMITATION DE FREQUENCE QUI INTERDIT AU SIGNAL DE L'OSCILLATEUR DE DEPASSER UNE SECONDE LIMITE SUPERIEURE. L'INVENTION S'APPLIQUE NOTAMMENT A DES STIMULATEURS CARDIAQUES IMPLANTABLES.
