Abstract

L'invention concerne un stimulateur 12 implantable et adaptable à modes multiples. Il comporte notamment un micro-processeur et une mémoire dans laquelle sont chargés différents programmes de stimulation. Il comporte également une liaison 15 de transmission avec l'extérieur, par haute fréquence ou par voie acoustique, permettant de passer d'un programme de stimulation à un autre ou de modifier les programmes qui sont en mémoire. L'invention s'applique notamment à des stimulateurs cardiaques.The invention relates to an implantable and adaptable multi-mode stimulator 12. In particular, it comprises a microprocessor and a memory in which various stimulation programs are loaded. It also comprises a transmission link with the outside, by high frequency or by acoustic means, making it possible to switch from one stimulation program to another or to modify the programs which are in memory. The invention applies in particular to cardiac pacemakers.
