ELECTRICAL TREATMENT OF BRONCHIAL CONSTRICTION
First Claim
Patent Images
1. A method of treating a medical disorder in a patient, the method comprising:
- advancing an introducer through a percutaneous penetration in a neck of a patient to a target site at or near a vagus nerve of a patient;
introducing one or more electrodes through the introducer to the target site;
positioning the one or more electrodes adjacent the vagus nerve exterior to a carotid sheath;
generating an electrical impulse from a location exterior to the patient; and
transmitting the electrical impulse through the neck of the patient to the one or more electrodes such that the electrical impulse is applied to the vagus nerve, wherein the electrical impulse is sufficient to stimulate afferent parasympathetic nerve fibers to increase activity of said nerve fibers

11. A device for treating a medical disorder in a patient, the device comprising:
-
a source of electrical energy; an introducer configured for introduction through a percutaneous penetration in a neck of the patient; and one or more electrodes coupled to the source of electrical energy and configured for advancement through the introducer to a target site at or near a vagus nerve of the patient exterior to a carotid sheath; wherein the source of electrical energy is configured to generate an electrical impulse and to transmit the electrical impulse through the one or more electrodes to the vagus nerve, the electrical impulse being sufficient to stimulate afferent parasympathetic nerve fibers of the vagus nerve to increase activity of said nerve fibers - View Dependent Claims (12, 13, 14, 15, 16, 17)
