ABSTRACT:
An implantable hearing device for improvement of extreme partial and total hearing loss has a transducer mounted to the malleus of the ossicular chain by METABOND adhesive. The device responds to auditory vibrations of the malleus to establish an electrical signal in response thereto. For total hearing loss restoration, a speech processing unit is mounted inside the mastoid cavity having a intracochlear electrode which is inserted into the cochlea through the oval window to reach the nerve endings thereof and transmit speech signals capable of being understood by the brain. For total hearing loss a totally implantable system with a rechargeable battery, receiving antenna for remote control of on/off switch, volume, speech processor and programing is used with a biologic-electronic microphone activated by the implanted rechargeable battery to interact with implanted electronics for transmission of electrical signals from the transducer directly to the cochlear nerve endings.
