Abstract

L'invention concerne un dispositif et un système d'interrogation à distance d'un implant de diagnostic, qui utilise de l'énergie acoustique pour alimenter et/ou interroger le dispositif. L'énergie acoustique est utilisé pour exciter le dispositif depuis l'extérieur du corps d'un patient. L'analyse de la réponse du dispositif à cette excitation permet de déterminer l'état du dispositif. De plus, cette énergie acoustique peut être utilisée pour alimenter le dispositif en puissance utile.
