  • Patent number: 8216123
    Abstract: An implantable middle ear hearing device having a tubular vibration transducer to drive a round window is designed to input sound to a round window opposite an oval window in an inner ear. The tubular vibration transducer has a unique structure that does not attenuate the magnitude of a signal, particularly, in a high frequency band. Sound delivery effect is much higher than those of conventional schemes. It is also possible to minimize difficulties associated with and problems resulting from the operation, which the conventional methods would have. Further, the transducer can have a relatively less compact than ossicle contact type transducers, and thus be easily fabricated. The hearing device can be applied to a sensorineural hearing loss patient with the ossicle damaged. Moreover, since sound is directly transmitted without through the ear drum and the ossicle, high efficiency sound delivery is achievable and hearing loss compensation are easy.
