Embodiment Construction

[0053] The present specification discloses methods and systems for switching the polarity of stimulation electrodes to more effectively treat symptoms of a biological system. In one embodiment, a system includes an implantable pulse generator operably connected to two or more stimulating electrodes. Stimulating electrodes are positioned adjacent to the target tissue, and electrical pulses are sent from the pulse generator to the electrodes to electrically stimulate the tissue, resulting in amelioration of a particular symptom. Improvement can be measured by patient-reported reduction in symptoms, reduction in patient need for medication, and / or diagnostic testing. In various embodiments, the polarity of one or more first electrodes of the system is switched to hyperpolarization (depolarization), and the polarity of one or more second electrodes is switched to subpolarization. Then observe the effect of polarity switching. If the patient improves, specific stimulation paramet...

Abstract

Methods for electrically stimulating body tissues to improve function or reduce symptoms provide an electrical stimulation system having two or more electrodes that are capable of being switched independently from a hyperpolarizing (depolarizing) state to a hypopolarizing state. Multiple combinations of hyperpolarizing electrodes and hypopolarizing electrodes are created by polarity switching to determine a polarity configuration having the best performance as determined by symptom reporting and clinical diagnostic tests. Polarity switching is triggered manually or is programmed to be switched automatically. Determining the configuration providing electrical stimulation resulting in the greatest benefit allows the system to be operated with one or more electrodes in a hypopolarizing state, thereby reducing energy requirements, tissue tolerance, and tissue fatigue.
