  • Publication number: 20090131742
    Abstract: The present invention relates to a round window driving transducer for easy implantation and an implantable hearing device having the same. The round window driving transducer is implantable in the round window of the cochlea in the middle ear cavity, and has excellent high frequency characteristics, which can assist patients with sensorineural hearing loss to hear sound better. The round window driving transducer can be placed inside the middle ear cavity, radiate sound with high efficiency, and be implanted by surgery using a fixing part formed with shape memory alloy, shape memory resin, or a bendable spring structure. Further, the round window driving transducer can overcome problems of the prior art, such as a difficult surgery and low vibration efficiency, which would inevitably occur when floating mass transducers are implanted in a drilled groove in the bone or when various types of piezoelectric transducers are implanted in the round window.

  • Publication number: 20090023976
    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.

  • Patent number: 6046312
    Abstract: Disclosed are water soluble azo dyes, represented by Formula I or II, and their synthesis and use. The water soluble azo dyes are synthesized by diazotizing 4-aminopyridine and coupling the resulting diazo intermediate with alkylated metanilic or orthanilic acid. To be suitable for measuring blood glucose levels, the dyes are combined with m-nitrophenyl boronic acid in an aqueous solvent. A combined ao form of the dyes with glucose shows a peak at 540 nm. At this wavelength, the absorptivity has a tendency to increase with the increasing of glucose level, which allows the measurement of blood glucose levels. ##STR1## wherein R has a 1-4 carbon atom length and is an alkyl, a hydroxy alkyl, a carboxyl-containing alkyl, or a sulfonyl-containing alkyl.
