Described is a method for treating a bronchial tissue. A guide wire is inserted through a bronchial passage to a desired location relative to a target portion of tissue to be treated. A catheter is slid along the guide wire with the guide wire received in a first lumen of the catheter until the guide wire exits a proximal port of the first lumen. A stiffening member is inserted into a second lumen of the catheter. A fluid is injected through the second lumen to a distal port of the catheter, so that the fluid is supplied to the bronchial tissue.
