Title (EN) COCHLEAR IMPLANT WITH SHAPE MEMORY MATERIAL AND METHOD FOR IMPLANTING THE SAME
(FR) IMPLANT COCHLEAIRE REALISE DANS UN MATERIAU A MEMOIRE DE FORME ET PROCEDE D'IMPLANTATION DE CE DERNIER
Abstract:
(EN) A multi-electrode cochlear implant (10) is formed from a plurality of metal wires (14) wound around a flexible tube (12) enclosing a shape memory core, held in place by a further layer of dielectric insulating material (18), and exposed at selected locations on the surface of the further layer to form the electrodes. After insertion of the implant, the shape memory material is warmed either by attached wires or adjacent heating elements to permit the implant to adapt to its effective shape.
(FR) La présente invention concerne un implant cochléaire (10) à électrodes multiples réalisé à partir de plusieurs fils métalliques (14) enroulés autour d'un tube flexible (12) renfermant un noyau à mémoire de forme, maintenus en place par une autre couche de matériau isolant diélectrique (18), et exposés en des emplacements choisis sur la surface de cette autre couche afin de former les électrodes. Après avoir inséré l'implant, on chauffe le matériau à mémoire de forme au moyen de fils attachés ou d'éléments chauffants adjacents afin que l'implant puisse adopter sa forme utile.
