Systems and methods for electrical stimulation of sphenopalatine ganglion and other branches of cranial nerves

摘要

Devices, systems and methods are disclosed for modulating cranial nerves, such as the sphenopalatine ganglion, to treat a medical condition of a patient, such as cluster headache. A stimulation device is advanced transnasally to a target site at or adjacent to the nasopharyngeal mucosa posterior to the middle turbinate. Electrical impulses are applied through one or more electrodes in the stimulation device to the target nerve sufficient to modulate the nerve and treat the medical condition.

主权项

1. A system for modulating a cranial nerve to treat a medical condition of a patient comprising:
a stimulation device comprising one or more electrodes configured for advancement through a nostril of a patient to a target site adjacent to or near the cranial nerve and one or more antennas; a power source configured for positioning externally to a patient and further configured to transmit electrical energy wirelessly through an outer skin surface of the patient to the stimulation device at the target site, wherein the one or more antennas are configured for receiving the electrical energy from the power source at the target site; a pulse generator coupled to the power source and the stimulation device and configured to apply one or more electrical impulses to the electrodes sufficient to modulate the cranial nerve.
