A method for treating asthma in a subject includes inserting a therapy delivery device into a vessel of a subject. The therapy delivery device is advanced to a point substantially adjacent an intraluminal target site of the autonomic nervous system. Next, the therapy delivery device is activated to deliver a therapy signal to the intraluminal target site to treat the asthma. The intraluminal target site is in electrical communication with nervous tissue selected from the group consisting of a spinal nerve, pre- or post-ganglionic autonomic fibers, a sympathetic chain ganglion, a thoracic sympathetic chain ganglion, a cervical ganglion, a lower cervical ganglion, an inferior cervical ganglion, an intramural ganglion, a splanchnic nerve, an esophageal plexus, a cardiac plexus, a pulmonary plexus, an anterior pulmonary plexus, a posterior pulmonary plexus, a celiac plexus, a hypogastric plexus, an inferior mesenteric ganglion, a celiac ganglion, and a superior mesenteric ganglion.
