  • Publication number: 20240207602
    Abstract: Systems and methods for delivering pharmaceutical compositions to the nasal cavity using iontophoresis. The systems and methods include a delivery system that is disposed in operative apposition with a tissue surface, which delivery system can circulate iontophoretic solution having ions of a therapeutic substance in the nasal cavity. The circulation can be continuous or periodic. The circulation can replace the iontophoretic solution within the nasal cavity over a period of time, such as from 15 seconds to 1 minute. The systems and methods further include an electrode device that is utilized to apply current to perform the iontophoresis while the circulating of the iontophoretic solution in the nasal cavity. In some embodiments, the therapeutic substance is a steroid, and in further embodiments, the ions are betamethasone ions.

  • Patent number: 12011587
    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.

  • Publication number: 20220202749
    Abstract: Methods of making and using pharmaceutical compositions for iontophoresis that include selecting an isotonic pharmaceutical composition that has ions of active and non-active ingredients and reducing/removing the ions of the non-active ingredients from the pharmaceutical composition to produce a revised pharmaceutical composition. The revised pharmaceutical composition is thereafter utilized for iontophoresis in an iontophoresis system. During the step of performing iontophoresis with the revised pharmaceutical composition for a pre-determined dosage, ramp-up period, maximum current, overall time, etc., can be reduced, as compared to performing iontophoresis with the isotonic pharmaceutical composition to provide the pre-determined dosage.

  • 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.
