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.

Totally implantable cochlear implant for improvement of partial and

A partially implantable hearing device for improvement of partial and total hearing loss has a high coercivity post type permanent target magnet mounted to the ossicular chain by METABOND adhesive and being driven by a cylidrically shaped air core driving coil extending around the post magnet in a contactless manner. The drive coil responds to auditory vibrations sensed by an externally concealed unit which converts these signals to an electrical signal transmitted to an externally located antenna which transmits same to an internally mounted antenna electronically connected to the air core electromagnetic driving coil to improve partial hearing loss. 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 non rechargeable or 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 signal directly to the cochlear nerve endings.

Electromagnetic implantable hearing device for improvement of partial

An improved partially implantable hearing device has a high coercivity permanent target magnet mounted to the ossicular chain by METABOND adhesive and being driven by an air core driving coil optimally implanted in a contactless manner at a spacing of approximately 1 mm. therefrom. The drive coil responds to auditory vibrations sensed by an externally concealed unit which converts these signals to an electrical signal transmitted to an externally located antenna which transmits same to an internally mounted antenna electronically connected to the air core electromagnetic driving coil.

Semi-implantable middle ear hearing device

Partially implantable hearing device having easily replaceable components. Outer ear canal units contain the microphone, power source and electronics for receiving acoustic energy or sound waves and converting them into a responsive and variable magnetic field. Magnetic fields of magnets implanted onto bones in the ossicular chain in the ear interact with the variable magnetic field to cause the bones in the ossicular chain to vibrate in response to received sound waves. The variable magnetic field can be created directly via electrical signals or indirectly wherein intermediate radio frequency waves are transmitted and received between external and implanted components.
