Beschreibung
Zusammenfassung:	A valve to perform lung volume reduction procedures is described. The valve is formed of a braided structure that is adapted for endoscopic insertion in a bronchial passage of a patient's lung. The braided structure has a proximal end and a distal end and is covered with a non porous coating adapted to prevent flow of air into the. A constricted portion of the braided structure is used to prevent flow of air through a central lumen of the structure, and to define at least one funnel shaped portion. The funnel shaped portion blocks the flow of air towards the constriction, i.e. towards the core of the lung. At least one hole is formed in the braided structure to permit flow of mucus from the distal end to the proximal end, to be expelled out of the lungs.
