Abstract
A round window coupling device is described for a hybrid electric-mechanical stimulation hearing implant system. A rigid outer shell securely fits into a round window niche in a cochlear outer surface of a recipient patient. An electrode groove in the outer surface of the outer shell snuggly fits around a portion of a cochlear implant electrode array passing through the round window niche. A coupling filling is enclosed within the outer shell to couple mechanical vibrations from the proximal end to the distal end with minimal attenuation. A transducer receiver at the proximal end connects to and receives vibrations from a drive surface of a mechanical transducer. And a drive face at the distal end interfaces to perilymph fluid within the cochlea of the recipient patient to deliver vibrations from the coupling filling to the perilymph fluid with minimal attenuation for perception as sound.
