         21 . A method for delivering energy to an airway wall of a human lung so as to treat asthma, the method comprising:
 advancing a device into an airway of a human lung;   delivering energy to a wall of the airway with the device so as to treat asthma; and   suctioning or delivering fluid from or to the airway while the device is within the airway.   
     
     
         22 . The method of  claim 21 , wherein suctioning or delivering fluid is carried out simultaneously or sequentially with energy delivery. 
     
     
         23 . The method of  claim 21 , wherein suctioning or delivering fluid is carried out through an opening between a bronchoscope working channel and an outer surface of the device. 
     
     
         24 . The method of  claim 21 , wherein suctioning or delivering fluid is carried out through a lumen in the device. 
     
     
         25 . The method of  claim 21 , further comprising cooling the airway wall.
