    摘要： An exemplary method includes an electro-acoustic stimulation (EAS) system associated with a user 1) processing sounds sensed by a first microphone coupled to a cochlear implant portion of the EAS system, 2) applying electrical stimulation representative of the sounds sensed by the first microphone by way of a plurality of electrode contacts located in a basal region of a cochlea of the user, 3) processing sounds sensed by a second microphone coupled to a hearing aid portion of the EAS system, 4) broadcasting, way of a speaker, amplified sound signals representative of the sounds sensed by the second microphone into an ear canal of the user, and 5) acoustically separating the second microphone from the speaker to avoid feedback within the hearing aid portion of the EAS system. Corresponding methods and systems are also disclosed.

    摘要： An exemplary cochlear implant system includes a sound processing assembly configured to be external to a patient and first and second extension members coupled to the sound processing assembly. The sound processing assembly includes a sound processing unit configured to process an audio signal and transmit one or more control parameters based on the audio signal to an implantable cochlear stimulator and a battery module configured to be electrically coupled to the sound processing unit and provide operating power to the sound processing unit. The first extension member has a distal portion configured to be coupled to a first ear of the patient and the second extension member has a distal portion configured to be coupled to a second ear of the patient. The first and second extension members typically extend back from the ears, thus positioning the sound processing assembly behind the patient's head.

    摘要： A system for mechanically assisted insertion of an electrode includes: an insertion tool configured to insert the electrode into biological tissues; and a controller configured to control the insertion tool, in which the controller is further configured to select operating parameters comprising a maximum allowable force profile from a library of operating parameters, in which the maximum allowable force profile is generated from data recorded during a number of previous successful operations. Also, a method for insertion of a cochlear lead, includes: selecting operating parameters comprising a maximum allowable force profile from a library of operating parameters; inserting the cochlear lead while sensing real time force and position; and continuing the insertion while the real time force is below the maximum allowable force profile, in which the maximum allowable force profile is generated from data recorded during a number of previous successful operations.

    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.
