Title (EN) IMPLANTABLE MICROPHONE FOR COCHLEAR IMPLANTS AND THE LIKE
(FR) MICROPHONE IMPLANTABLE POUR IMPLANTS COCHLEAIRES ET AUTRES DISPOSITIFS DU MEME TYPE
Abstract:
(EN) A system for assisting a person with a hearing disability includes an implantable microphone (40A) which senses sounds by monitoring pressure variations in the cochlear fluid (36). The electrical signal generated by the microphone (40A) is processed and used by a signal generator (44), such as a cochlear implant to generate excitation signals for the patient. In this manner, external microphones, used in prior art systems, are eliminated.
(FR) Un système permettant d'aider une personne souffrant d'une perte de l'audition comprend un microphone implantable (40A) qui détecte les sons en surveillant les variations de pression à l'intérieur du liquide cochléaire (36). Le signal électrique généré par le microphone (40A) est traité et utilisé par un générateur de signaux (44), tel qu'un implant cochléaire, pour générer des signaux d'excitation destinés au patient. Ce dispositif permet d'éliminer les microphones externes utilisés dans les systèmes antérieurs.
