ABSTRACT:
A totally implanted hearing device is located within a dry cavity formed in the mastoid area of the human skull to house and mount the device and associated electronic hardware allowing the bypass of the middle ear's oscicullar chain. The device uses spring prosthesis coupled to sense the vibrations of the tympanic membrane and transmit same to the electronic hardware which senses, amplifies, and which transmits the amplified signal to a transducer which is connected to a piston which vibrates the parilymph fluid of the inner ear to achieve enhanced hearing free of feedback and distortion.
