    摘要: A combination, voltage converter circuit for use within an implantable device, such as a microstimulator, uses a coil, instead of capacitors, to provide a voltage step up and step down conversion functions. The output voltage is controlled, or adjusted, through duty-cycle modulation. In accordance with one aspect of the invention, applicable to implantable devices having an existing RF coil through which primary or charging power is provided, the existing RF coil is used in a time-multiplexing scheme to provide both the receipt of the RF signal and the voltage conversion function. This minimizes the number of components needed within the device, and thus allows the device to be packaged in a smaller housing or frees up additional space within an existing housing for other circuit components. In accordance with another aspect of the invention, the voltage up/down converter circuit is controlled by a pulse width modulation (PWM) low power control circuit. Such operation allows high efficiencies over a wide range of output voltages and current loads.

    摘要: A voltage converter for use within small implantable electrical devices, such as a microstimulator, uses a coil, instead of capacitors, to provide a voltage step up and step down function. The output voltage is controlled, or adjusted, through duty-cycle modulation. Good efficiencies are achieved for virtually any voltage within the compliance range of the converter. In accordance with one aspect of the invention, applicable to implantable devices having an existing RF coil through which primary or charging power is provided, the existing RF coil is used in a time-multiplexing scheme to provide both the receipt of the RF signal and the voltage conversion function. This minimizes the number of components needed within the device, and thus allows the device to be packaged in a smaller housing, or frees up additional space within an existing housing for other circuit components. In accordance with another aspect of the invention, the voltage up/down converter circuit is controlled by a pulse width modulation (PWM) low power control circuit. Such operation allows high efficiencies over a wide range of output voltages and current loads. The invention thus provides a voltage converter circuit for use within an implantable device that is compact, efficient, and provides a wide range of output voltages and currents.

    摘要: A hearing prosthesis includes both a hearing aid adapted to sense and amplify low frequency acoustic sound signals and a cochlear implant system adapted to sense high frequency acoustic sound signals. The hearing aid has a first microphone adapted to sense the low frequency acoustic sound signals, amplify these sensed low frequency acoustic sound signals, and present the resulting amplified low frequency acoustic sound signals in the ear canal of a user, thereby enabling the user to better hear these amplified sounds using his or her normal hearing processes. The cochlear implant system includes a second microphone adapted to sense the high frequency acoustic sound signals and selectively stimulate the inner ear with electrical stimulation that will be perceived as high frequency acoustic sound signals. Both the cochlear implant system and the hearing aid system are coupled to operate on the same ear of the user. Feedback within the hearing aid portion of the system is eliminated by positioning the first microphone at a location that is acoustically remote from the ear canal where the amplified low frequency acoustic sound signals are presented. High frequency acoustic sound signals are better sensed by placing the second microphone at a location that is in or near the ear canal where the amplified low frequency acoustic sound signals are presented.

    摘要: A method for configuring stimulation pulses in an implantable stimulator device having a plurality of electrodes is disclosed, which method is particularly useful in adjusting the electrodes by current steering during initialization of the device. In one aspect, a set of ideal pulses for patient therapy is determined, in which at least two of the ideal pulses are of the same polarity and are intended to be simultaneous applied to corresponding electrodes on the implantable stimulator device during an initial duration. These pulses are reconstructed into fractionalized pulses, each comprised of pulse portions. The fractionalized pulses are applied to the corresponding electrodes on the device during a final duration, but the pulse portions of the fractionalized pulses are not simultaneously applied during the final duration.
