Title: (DE) COCHLEAIMPLANTAT MIT KLIPPMAGNET
(EN) COCHLEAR IMPLANT WITH CLIPPABLE MAGNET
(FR) IMPLANT COCHLÉAIRE À AIMANT POUVANT ÊTRE ACCROCHÉ
Abstract:
(EN) An implantable medical device includes an implantable coil case that contains a communications coil. A magnet receptacle is located within the coil case at the radial center and has a magnet opening in one of the lateral surface or the medial surface of the coil case. A magnet fitting groove is recessed into one of the lateral or medial surface of the coil case and extends from the magnet opening to the outer circumference of the coil case. A u-shaped implant magnet clip has parallel clip legs that are connected at a closed end of the u-shape, and an implant magnet is attached to one of the clip legs. The coil case and the magnet clip are configured to cooperate for a portion of the coil case to fit between the clip legs and the implant magnet to slide through the magnet fitting groove and fit through the magnet opening into the magnet receptacle.
(FR) L’invention concerne un dispositif médical implantable qui inclut une enceinte de bobine implantable qui contient une bobine de communications. Un réceptacle d’aimant est situé dans l’enceinte de bobine au centre radial et comporte une ouverture d’aimant dans une des surfaces latérales ou dans la surface médiale de l’enceinte de bobine. Une rainure d’insertion d’aimant est creusée dans une des surfaces latérales ou médiales de l’enceinte de bobine et s’étend de l’ouverture d’aimant à la circonférence extérieure de l’enceinte de bobine. Un crochet d’aimant d’implant en forme de U comporte des jambes de crochet parallèles qui sont reliées à une extrémité fermée de la forme de U, et un aimant d’implant est fixé à l’une des branches de crochet. L’enceinte de bobine et le crochet d’aimant sont conçus pour coopérer pour qu’une partie de l’enceinte de bobine s’insère entre les jambes de crochets et que l’aimant d’implant coulisse à travers la rainure d’insertion d’aimant et s’insère à travers l’ouverture d’aimant dans le réceptacle d’aimant.
