CA 2364811

A fixation element for an implantable microphone is disclosed. In a preferred embodiment the fixation element comprises an essentially cylindrical portion adapted to be inserted into a bore which crosses a wall of the auditory canal of a user, said cylindrical portion, at least in an implanted state of the fixation element, surrounding an outer circumferential portion of a housing part of the microphone, which housing part is provided with a sound receiving member. The cylindrical portion includes at least one elastic region of increased diameter, said elastic region contacting, in the implanted state of the fixation element, a wall of said bore and providing, by elastic restoring forces, for a friction which is sufficiently high to fix said cylindrical portion in at least one of the two axial directions of said bore.

Voici un nouvel élément de fixation pour microphone implantable. L'une des formes préférées du dispositif comprend une partie principalement cylindrique conçue pour être insérée à l'intérieur d'un alésage passant à travers une paroi du canal auditif d'un utilisateur. Ladite partie cylindrique, au moins une fois l'élément de fixation implanté, entoure la partie extérieure de l'enveloppe du microphone, ladite enveloppe comprenant un élément de réception du son. La partie cylindrique comprend au moins une zone élastique d'un diamètre supérieur, ladite zone élastique venant au contact de l'une des parois dudit alésage une fois l'élément de fixation implanté, et fournit, par élasticité, une force de friction suffisamment importante pour maintenir ledit cylindre dans au moins l'un des deux axes dudit alésage.
