A method of reducing bronchial constriction in a subject includes delivering energy to create one or more lesions on a main bronchus so as to transect pulmonary nerves sufficiently to reduce bronchial constriction in a lung of the patient distal to the main bronchus. The memory devices are comprised by an active layer of resistive memory material interposed between upper electrodes and lower electrodes. Also the apparatus has first and second covers that open and close the first and second openings, respectively, and an interlocking mechanism that causes the pressure mechanism to move the one of the heating member and the backup member in conjunction with movement of the first cover and the second cover. The swiveling motion of the release lever is not transferred to the Bowden traction cord, since the release lever can move along a Bowden traction cord suspended in the release lever.
