IMPLANTABLE ELECTROMAGNETIC MIDDLE-EAR BONE-CONDUCTION HEARING AID DEVICE

摘要

An implantable electromagnetic middle-ear bone conduction hearing aid device is disclosed which provides variability to meet a variety of pathological entities of the hearing impaired user. The device utilizes a sound processing component for converting sound into an analog electromagnetic signal and has an output transmitter adapted to be placed supercutaneously on the skull of the user for transmitting the electromagnetic signal transcutaneously. A signal receiving and transmitting component is adapted to be implanted subcutaneously in the bone of the user outside of the middle ear for receiving the transcutaneous electromagnetic signal from the sound processing component and for transmitting the electromagnetic signal subcutaneously into the middle-ear of the user. A vibration generating component is adapted to be implanted in any of the small bones of the ossicular chain in the middle-ear for receiving the subcutaneous electromagnetic signal from the signal receiving and transmitting component and for vibrating the ossicular chain in response to such electromagnetic signal to stimulate normal functioning of the inner ear to create the perception of sound in the hearing impaired user.
