Claim 14:
15. A system for stimulating neural activity in a vagal nerve of a patient to treat bronchoconstriction in the patient, the system comprising:
at least one transducer, configured to be in signaling contact with a pulmonary branch of a vagal nerve, the at least one transducer configured to be at least partially implanted in the patient; and
a voltage or current source configured to generate a signal to be selectively applied to afferent A fibers of the vagal nerve of the patient, while not stimulating efferent fibers or afferent Aδ fibers, via the at least one transducer, wherein the signal has a frequency of 50-150 Hz, and wherein the signal has a pulse duration of between 0.005 and 0.1 ms, such that the signal to the vagal nerve produces an improvement in a physiological parameter indicative of treating bronchoconstriction in the patient, wherein the system further comprises a detector for detecting the physiological parameter, and
wherein the improvement in the physiological parameter is a decrease in airway smooth muscle tone, an increase in blood oxygen saturation, a decrease in blood carbon dioxide concentration, an increase in tidal mid-expiratory flow, a decrease in respiratory rate, an increase in total lung capacity, or an increase in forced expiration volume, from an initial measurement.
