  • Publication number: 20210268273
    Abstract: Various systems and methods provide iontophoretic delivery of anesthesia at a patient's tympanic membrane. At least one example is a method including: performing iontophoresis within a first ear canal by driving, by a control unit, a DC signal to an electrode of a first iontophoresis device positioned within the first ear canal, the electrode at least partially submerged within an iontophoresis fluid within the first ear canal; measuring, by the control unit, a mixed capacitance associated with the electrode by driving a first AC signal having a first frequency to the electrode; and determining, based on a change in the mixed capacitance, that an air bubble is present in the iontophoresis fluid.

  • Patent number: 10987512
    Abstract: Various systems and methods provide iontophoretic delivery of anesthesia at a patient's tympanic membrane. Some implementations provide channel switching enabling a single current sink to pull current through two electrodes in an alternating fashion based on clock pulses. The iontophoretic delivery of anesthesia may be driven by an AC modulated current. Some implementations provide for continuous flow of fresh iontophoresis fluid to the ear canal during iontophoresis. The fluid flows from a source reservoir into the cavity between the tympanic membrane and a plug, and then drains out of the cavity to a reservoir. An iontophoresis system may also detect capacitance between an anode electrode and an auxiliary electrode in a patient's ear canal, watching for reduced capacitance to indicate presence of a bubble in the iontophoresis fluid.

  • Patent number: 8555891
    Abstract: Techniques for operating a subcutaneous implant device are disclosed. The implant device can be formed of a non-magnetic material that is compatible with diagnostics such as magnetic resonance imaging (MRI) and can include a rotor element that rotates under the influence of an external magnetic field. The implant device includes a tension relief mechanism for relieving excessive force applied between the implant device and a portion of a patient's tongue. A non-implanted device can include a stator and drive circuitry for generating the external magnetic field. The non-implanted device can receive a user command and can vary the external magnetic field based on the command. When activated by the magnetic field, the implant device can change its operating state to interact with the patient's body.
