Title (EN) MRI-SAFE AND FORCE-OPTIMIZED IMPLANTABLE RING MAGNET SYSTEM WITH AN ENHANCED INDUCTIVE LINK
(FR) SYSTÈME D'AIMANT ANNULAIRE IMPLANTABLE SANS DANGER POUR L'IRM ET À FORCE OPTIMISÉE AVEC LIAISON INDUCTIVE AMÉLIORÉE
Abstract:
(EN) A magnetic system for a medical implant system is described. A planar implant receiver coil is configured to lie underneath and parallel to overlying skin of an implanted patient for transcutaneous communication of an implant communications signal. A planar ring-shaped attachment magnet also is configured to lie underneath and parallel to the overlying skin and radially surrounds the receiver coil. The attachment magnet is characterized by a magnetic field configured to avoid creating torque on the attachment magnet in the presence of an external magnetic field.
(FR) La présente invention concerne un système magnétique pour un système d’implant médical. Une bobine de récepteur d'implant plane est configurée pour se trouver en dessous de, et parallèle à, la peau sus-jacente d'un patient portant un implant pour une communication transcutanée d'un signal de communication d'implant. Un aimant de fixation annulaire plan est également conçu pour se trouver au-dessous de, et parallèle à, la peau sus-jacente et entourer radialement la bobine de réception. L'aimant de fixation est caractérisé par un champ magnétique configuré pour éviter la création d'un couple sur l'aimant de fixation en présence d'un champ magnétique externe.
