Abstract[English]
Presented herein are implantable housing arrangements that are configured to receive and retain an implantable magnet therein, while also facilitating both in-plane rotation and out-of-plane rotation of the implantable magnet in the presence of external magnetic, such as that applied with an MRI. That is, the housing arrangements presented herein allow a planar (e.g., conventional/standard) implantable magnet to rotate circumferentially around a central axis of the implantable magnet (in-plane rotation), as well as angularly rotate relative to the central axis (out-of-plane rotation). The in-plane rotation and out-of-plane rotation can reduce torque during an MRI because the magnet is able to rotate so as to more closely align with the applied MRI magnetic field, resulting in less pain and less risk of tissue or device damage.[French]
L'invention concerne des agencements de boîtier implantables qui sont configurés pour recevoir et retenir un aimant implantable à l'intérieur de ceux-ci, tout en facilitant également à la fois la rotation dans le plan et la rotation hors du plan de l'aimant implantable en présence d'un champ magnétique externe, tel que celui appliqué avec une IRM. C'est-à-dire que les agencements de boîtier présentés dans la description permettent à un aimant implantable plan (par exemple classique/standard) de tourner circonférentiellement autour d'un axe central de l'aimant implantable (rotation dans le plan), ainsi qu'angulairement par rapport à l'axe central (rotation hors plan). La rotation dans le plan et la rotation hors du plan peuvent réduire le couple pendant une IRM car l'aimant peut tourner de manière à s'aligner plus étroitement avec le champ magnétique d'IRM appliqué, ce qui entraîne moins de douleur et moins de risque de dommages aux tissus ou à l'appareil.
