A magnetic implant for treating sleep disorders includes a first anchor (25), a first magnet (22) coupled to the first anchor, a tongue anchor (36), a second magnet (38) coupled to the tongue anchor, and a support (30) for aligning the first and second magnets so that a repelling force is generated between the magnets for urging the second magnet away from the first magnet. In one embodiment, the support aligns a magnetic pole of the first magnet with a repelling magnetic pole of the second magnet, guides movement of the first and second magnets relative to one another, and maintains the first magnet at a fixed distance from the first anchor. In one embodiment, the repelling force urges the second magnet toward the first anchor. The first anchor may be connected to bone or soft tissue.

L'invention concerne un implant magnétique pour traiter des troubles du sommeil, comprenant un premier ancrage (25), un premier aimant (22) accouplé au premier ancrage, un ancrage de langue (36), un second aimant (38) accouplé à l'ancrage de langue, et un support (30) pour aligner les premier et second aimants, de sorte qu'une force de répulsion est générée entre les aimants, pour pousser le second aimant loin du premier aimant. Dans un mode de réalisation, le support aligne un pôle magnétique du premier aimant avec un pôle magnétique de répulsion du second aimant, guide un déplacement des premier et second aimants l'un par rapport à l'autre, et maintient le premier aimant à une distance fixe du premier ancrage. Dans un mode de réalisation, la force de répulsion pousse le second aimant vers un premier ancrage. Le premier ancrage peut être relié à un os ou à un tissu mou.
