Title
(EN) ADVANCED IMPLANTED MAGNET MANAGEMENT IN THE FACE OF EXTERNAL MAGNETIC FIELDS
(FR) GESTION AVANCÉE D'AIMANTS IMPLANTÉS FACE À DES CHAMPS MAGNÉTIQUES EXTERNES
Abstract
(EN)
A method, including subjecting a subcutaneous medical device containing a first magnet to a magnetic field of an MRI machine, thereby imparting a torque onto the first magnet and resisting the imparted torque via an external device that includes a second magnet, wherein the second magnet is movable relative to another component of the external device.
(FR)
L'invention concerne un procédé, comprenant la soumission d'un dispositif médical sous-cutané contenant un premier aimant à un champ magnétique d'une machine d'IRM, transmettant ainsi un couple au premier aimant et résistant au couple transmis par l'intermédiaire d'un dispositif externe qui comprend un deuxième aimant, le deuxième aimant étant mobile par rapport à un autre élément du dispositif externe.
