  • 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.

  • 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: 10918525
    Abstract: A tympanostomy tube delivery device comprises a shaft assembly, a pressure equalization tube, and a sensor. The shaft assembly comprises a cannula and a pusher operable to translate relative to the cannula. The pressure equalization tube is positioned within the shaft assembly. The pusher is operable to drive the pressure equalization tube out of the shaft assembly. The sensor is operable to detect a physical parameter associated with engagement between the distal end of the shaft assembly and a tympanic membrane. A controller may activate a feedback device to inform an operator that the distal end of the shaft assembly has achieved suitable apposition with the tympanic membrane, based on information from the sensor.

  • Patent number: 10653446
    Abstract: A tympanostomy tube delivery device comprises a body, a cannula extending distally from the body, and a cylindraceous member disposed within the cannula. The cylindraceous member comprises a tubular portion and a plurality of leaves positioned at the distal end of the tubular portion. The leaves are movable between a collapsed position and an expanded position. The cylindraceous member is slidable relative to the cannula to selectively expose the leaves relative to the open distal end of the cannula. A first leaf of the plurality of leaves has a sharp distal point configured to pierce a tympanic membrane and a longitudinally extending sharp edge. The cylindraceous member may be used to create and dilate a myringotomy incision in a tympanic membrane. The tympanostomy tube delivery device may then be used to deploy a tympanostomy tube through the myringotomy incision.

  • Patent number: 10195369
    Abstract: Systems and methods are described for administering a solution to a tympanic membrane of an ear canal of a subject. In some embodiments, the system includes a fluid delivery channel with a proximal end, a distal end, and a lumen defined therebetween. The proximal end can include at least one of a valve and Luer connector for selectively establishing fluid communication between a solution source and the lumen of the fluid delivery channel. The distal end can include an atraumatic tip defining a plurality of spray holes for providing fluid communication between the lumen and the ear canal. The atraumatic tip can be capable of being inserted into the ear canal and positioned near the tympanic membrane with the plurality of spray holes substantially facing the tympanic membrane to fill the ear canal with the solution from a portion near the tympanic membrane out toward an outer ear portion.
