Abstract
The specification discloses a trans-tympanic rod having a magnet at one end, and connected at the opposite end to a location in the middle ear, for transmitting the vibrations induced in the magnet by a magnetic induction hearing aid, to the inner ear. The rod can mate with the malleus by way of a set of prongs or by insertion in a hole in the malleus. Alternately, the rod can mate with a hole in an ossicular replacement prosthesis. Additionally, the rod can mate with a horseshoe shaped prosthesis located between the tympanic membrane and the malleus.
