Patent number: 11288981Abstract: A set of simulator hardware and software provide a realistic training environment for pressure equalization tube delivery to a tympanic membrane using a semi-automated pressure equalization tube delivery device (“PETDD”). An anatomically realistic ear model is attached to a touch sensitive display so that the ear model aligns with a displayed virtual image of the middle ear, creating a realistic view through the ear canal of the ear model. A training PETDD and other devices of the simulator provide pressure and location data for the training PETDD as a trainee inserts the PETDD tip into the ear canal to rest against the virtual TM and simulate a PE tube delivery event. Resulting data is examined to determine whether the simulated delivery would have been successful if it had been a real scenario.Type: GrantFiled: July 12, 2019Date of Patent: March 29, 2022Assignee: TUSKER MEDICAL, INC.Inventor: Nicholas E.

Patent number: 10987512Abstract: 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.Type: GrantFiled: November 19, 2018Date of Patent: April 27, 2021Assignee: TUSKER MEDICAL, INC.Inventors: Mahyar Z.
