Zephyr endobronchial valve system
Pulmonx’s Zephyr endobronchial valve system is an implantable device used to reduce over-inflation of the lungs due to severe emphysema in adults.
The device features a one-way silicone duckbill valve attached to a nickel-titanium self-expanding retainer that is covered with a silicone membrane.
Doctors can implant the device using a flexible bronchoscope and lead it through the airway to the diseased areas of the lung to allow for healthy parts of the lungs to expand and decrease shortness of breath. When a patient inhales, the valves close and stop air from entering the damaged part of the lungs.
