Abstract
An implanted hearing aid for deaf patient having an intact auditory nerve includes an implanted receiver unit provided with a receiver coil surrounding patient's auditory channel. An external transmitter unit is electrically connected to a separate transmitter coil embedded in a fitting piece insertable into the auditory channel in the range of the receiving coil so as to establish an optimum inductive coupling. A microphone is supported on an ear yoke and connected both to the transmitter and the receiver units. The receiver unit is electrically connected to an excitation electrode mounted on cochlea in patient's ear.
