A magnet assembly for location around portions of bones in the middle ear where one portion of the assembly is a magnet and another portion of the assembly is a magnetic material, the portions being hinged to one another so that they are held around the bone by the magnetic field and being adapted for optimal coupling with a magnetic field produced by a coil in a magnetic induction hearing aid.

Magnet for installation in the middle ear

A magnetic induction hearing aid where the microphone, the amplifying electronics, the battery and a coil are contained in a single housing which is located deep in the ear canal. A magnet is attached to portions of the middle ear by means of a malleus clip or by implantation between the tympanic membrane and the malleus. The magnet is vibrated by interaction with the magnetic field produced by the coil. Two amplifier designs are disclosed for use with different levels of hearing loss. The magnet can be coated with hydroxyapatite for permanent attachment to the body. The magnet is coated with hydroxyapatite by an ion implantation process, a plasma spraying technique or a method of applying the hydroxyapatite while a precoating polymeric material has not fully solidified.
