Abstract: Some embodiments relate to a method of reducing excess mucosa production and/or secretion in the respiratory tract, comprising: introducing into a respiratory tract lumen a device configured for damaging nerve tissue or blocking neural conduction in the surroundings of said lumen, the device comprising a plurality of energy emitters; positioning the energy emitters of the device inside the lumen at a distance from walls of the lumen; and activating the energy emitters to emit energy suitable to damage the nerve tissue enough to suppress parasympathetic nerve activity which causes excess mucosa production and/or secretion.
