(HealthDay)—A new device, the Zephyr Endobronchial Valve (Zephyr Valve), has been approved by the U.S. Food and Drug Administration for the treatment of breathing difficulties associated with severe emphysema.
During a procedure in a hospital setting, the Zephyr Valves are placed into the diseased areas of the lung airways using a flexible bronchoscope. The device is designed to prevent air from entering the damaged parts of the lung and allow the escape of trapped air and fluids.
Data were reviewed from a multicenter study of 190 patients with severe emphysema. A total of 128 patients were treated with Zephyr Valves and medical management, including medications and pulmonary rehabilitation, while the control group (62 patients) received medical management alone. At one year, 47.7 percent of patients treated with the Zephyr Valves and 16.8 percent of the control group experienced at least a 15 percent improvement in their pulmonary function scores. Approval for the device was granted to Pulmonx.
