(EN) FAR FIELD RADIATIVE POWERING OF IMPLANTABLE MEDICAL THERAPY DELIVERY DEVICES
(FR) ALIMENTATION PAR RAYONNEMENT DE CHAMP ÉLOIGNÉ POUR DES DISPOSITIFS D'ADMINISTRATION DE THÉRAPIE MÉDICALE IMPLANTABLES
Abstract
(EN)
A particular implantable device may include an antenna configured to receive a far field radiative signal. The implantable device may also include a voltage rectifier configured to rectify the far field radiative signal received by the antenna to provide a rectified voltage signal. The implantable device may further include a charge storage element operative to receive the rectified voltage signal and to store charge responsive to the rectified voltage signal. The implantable device may also include a therapy delivery unit powered by the charge storage element. The therapy delivery unit is operative to deliver a therapy to a patient.

(FR)
La présente invention a pour objet un dispositif implantable particulier qui peut comporter une antenne conçue pour recevoir un signal de rayonnement de champ éloigné. Le dispositif implantable peut aussi comporter un redresseur de tension conçu pour redresser le signal de rayonnement de champ éloigné reçu par l'antenne de sorte à fournir un signal de tension redressé. Le dispositif implantable peut comporter en outre un élément de stockage de charge efficace pour recevoir le signal de tension redressé et pour stocker une charge en réponse au signal de tension redressé. Le dispositif implantable peut aussi comporter une unité d'administration de thérapie alimentée par l'élément de stockage de charge. L'unité d'administration de thérapie est efficace pour l'administration d'une thérapie à un patient.
