Ossicular prosthesis for mounting magnet

摘要

A prosthesis for use with an intact ossicular chain to allow a magnet to be coupled to the ossicular chain, the magnet being moved by an electromagnetic induction hearing aid. The prosthesis has a body having a first groove which cooperates with the manubrium and a second groove formed by an arm extending from the body and a hooked end, the second groove cooperating with the long process. A magnet is connected to a planar surface developed by the arm and the hooked end and is generally parallel to the tympanic membrane when installed. A conventional disk shaped magnet can be utilized inside a biocompatible housing.
