Abstract: A method for treating a pulmonary condition in a subject includes one step of providing an implantable electrode assembly. The implantable electrode assembly includes a flexible member, at least one electrode operably secured to the flexible member, and an attachment mechanism for securing the at least one electrode to the flexible member. The implantable electrode assembly is implanted at a target site including an intraluminal location innervated by at least one nerve of the autonomic nervous system (ANS). The implantable electrode assembly is positioned at the target site such that the flexible member conforms to a portion of the inner surface of the target site, and the at least one electrode is positioned substantially adjacent the at least one nerve. Next, electric current is delivered to the at least one electrode to effect a change in the ANS of the subject.
