Abstract
We disclose a method of treating a medical condition in a patient using an implantable medical device including coupling at least a first electrode and a second electrode to a cranial nerve of the patient, providing a programmable electrical signal generator coupled to the first electrode and the second electrode, generating a first electrical signal with the electrical signal generator, applying the first electrical signal to the electrodes, wherein the first electrode is a cathode and the second electrode is an anode, reversing the polarity of the first electrode and the second electrode, yielding a configuration wherein the first electrode is an anode and the second electrode is a cathode, generating a second electrical signal with the electrical signal generator, applying the second electrical signal to the electrodes, reversing the polarity of the first electrode and the second electrode, yielding a configuration wherein the first electrode is a cathode and the second electrode is an anode, generating a third electrical signal with the electrical signal generator, and applying the third electrical signal to the electrodes. Each of the electrical signals can independently conta…
