A method for decreasing responsiveness or decreasing resistance to airflow of airways involves the transfer of energy to or from the airway walls to prevent or reduce airway constriction and other symptoms of lung diseases. The solid oxide fuel cell includes an electrolyte film sheet, a cathode, and an anode, and the anode includes a catalyst active layer sheet for inducing a reforming reaction of the supplied fuel. A plurality of dopants is introduced into the thinned substrate from the back surface. One or more support legs extend downwardly from a lower surface of the base and are adjustable in length. Generally S-shaped laparoscopic instruments placed through the C-shaped trocar sleeves or through the cannula and instrument holder unit provide markedly improved degrees of instruments’ freedom during trans-umbilical laparoscopic procedures.
