Abstract: A middle ear prosthesis device and corresponding implantation procedure are described. A sensing microphone converts an acoustic audio signal into a corresponding electrical audio signal. A sensing amplifier amplifies the electrical audio signal. An audio transducer converts the amplified electrical audio signal into a corresponding amplified acoustic audio signal. An acoustic waveguide conducts the amplified acoustic audio signal from the audio transducer to the middle ear and includes: i. a main tubular portion having an outer end for placement in the outer ear canal and an inner end for placement in the middle ear, and ii. an extension portion having an outer end coupleable to the audio transducer and an inner end coupleable to the outer end of the main tubular portion.

Abstract: The present invention relates to an improved acoustic prosthesis (1) having a direct action of medium ear, comprising a tubular shaped conveyor (12), canalising acoustic waves; at least a microphone picking up surrounding sounds; and amplifier, electrically connected with said microphone for amplifying picked up sounds at a suitable level; at least an audio transducer connected with said amplifier and said conveyor (12), said transducer transforming electric signals arriving from said acoustic wave amplifier, said acoustic waves being conveyed in said conveyor (12); and supply means for said amplifier and for said microphone; said acoustic prosthesis (1) being characterised in that said conveyor (12) comprises a main portion (12?), one end (12?a) of which can be placed within the medium ear (4) while its other end (12?b) can be placed within the outer ear (3) channel; and at least one more portion (12?, 12??) that can be coupled at the end of said main portion (12?) and at said at least an audio transducer.
