Title
(DE) INDUKTIVE SIGNAL- UND ENERGIEÜBERTRAGUNG DURCH DEN ÄUSSEREN GEHÖRGANG
(EN) INDUCTIVE SIGNAL AND ENERGY TRANSFER THROUGH THE EXTERNAL AUDITORY CANAL
(FR) SIGNAL INDUCTIF ET TRANSFERT D'ÉNERGIE À TRAVERS LE CANAL AUDITIF EXTERNE
Abstract
(EN)
An inductive coil arrangement is described for an ear canal of a recipient patient. An inner transmitter coil inserts into the ear canal for transmitting a communication signal through the skin of the outer wall of the ear canal. The transmitter coil includes transmission wire loops that lie substantially in a common plane which curves around the central axis of the ear canal conformal to the outer wall of the ear canal. An outer receiver coil is implantable under the skin of the outer wall of the ear canal for receiving the communication signal from the transmitter coil. The receiver coil includes receiver wire loops that lie substantially in a common plane which curves around the central axis of the ear canal substantially parallel to the transmitter coil.

L'invention concerne une bobine inductive pour un canal auditif d'un patient receveur. Une bobine de transmetteur intérieure est insérée dans le canal auriculaire pour transmettre un signal de communication à travers la peau de la paroi extérieure du canal auriculaire. La bobine de transmetteur comprend des boucles de fil de transmission qui se trouvent sensiblement dans un plan commun qui s'incurve autour de l'axe central du canal auriculaire pour épouser la paroi extérieure du canal auriculaire. Une bobine de récepteur extérieure peut être implantée sous la peau de la paroi extérieure du canal auriculaire pour recevoir le signal de communication en provenance de la bobine de transmetteur. La bobine de récepteur comprend des boucles de fil de réception qui se trouvent sensiblement dans un plan commun qui s'incurve autour de l'axe central du canal auriculaire sensiblement parallèlement à la bobine de transmetteur.
