Zephyr Valve to treat severe emphysema

September 14, 2018 0 By CH Unnikrishnan

Zephyr Endobronchial Valve to treat breathing difficulty associated with severe emphysema received clearance in the US.

The device is a less-invasive treatment option for people with emphysema who have severe symptoms that have not improved from taking medicines.

Zephyr Valves are similar in size to pencil erasers. Doctors can place them into the diseased areas of the lung airways during a procedure using a flexible bronchoscope in a hospital setting.

The design of the device is intended to prevent air from entering the damaged parts of the lung and to allow trapped air and fluids to escape. During inhalation, the valves close, preventing air from entering the damaged part of the lung. During exhalation, the valves open, letting out the trapped air, relieving the pressure.

The Zephyr Valve device is contraindicated for patients with active lung infections; those who are allergic to nitinol, nickel, titanium or silicone; active smokers and those who are not able to tolerate the bronchoscopic procedure.

Pulmonx’s Zephyr Valve device was granted Breakthrough Device designation by USFDA.
