Patent ID: 8849394

Claim:
A method for treating a patient using an iontophoresis electrode system, the patient having a head with a first ear and a second ear, the method comprising: (a) mounting a first iontophoresis electrode of the iontophoresis electrode system to the head of the patient so that the first iontophoresis electrode is aligned with a target tissue of the first ear; (b) applying a therapeutic or anesthetic agent to the first ear by energizing the first iontophoresis electrode prior to any remodeling of the patient's tympanic membrane in the first ear; and (c) applying a therapeutic agent to the second ear by energizing a second iontophoresis electrode of the iontophoresis electrode system prior to any remodeling of the patient's tympanic membrane in the second ear, wherein the electrodes are operatively coupled to iontophoresis driving circuitry of the iontophoresis electrode system, wherein the iontophoresis circuitry is configured for simultaneous application of the agent using the iontophoresis electrodes.
