| 发明名称 | Magnet arrangement for bone conduction hearing implant | ||
| 摘要 | An implantable magnet arrangement is described for a hearing implant in a recipient patient. A pair of implant magnets are fixable in a common plane beneath the skin of the patient to underlying skull bone. At least one of the magnets is adapted to transform a magnetic drive signal from an external signal drive coil into a corresponding mechanical stimulation signal for delivery by bone conduction of the skull bone as an audio signal to the cochlea. Each implant magnet includes a pair of internal magnets lying in parallel planes which meet along a common junction with repelling like magnetic polarities facing towards each other, and the magnetic polarities of each implant magnet are reversed from each other. | ||
