New theory addresses frozen Earth paradox
WASHINGTON, Oct. 24 (UPI) -- The U.S. Food and Drug Administration has approved a removable valve system designed to control prolonged air leaks in the lungs.
The FDA said the IBV Valve System is approved for use in patients who have undergone partial or total removal of a lung lobe or lung volume reduction surgery and who experience air leaks that last more than seven days. The device was approved as part of program supporting the development of medical devices intended to benefit patients with diseases or conditions affecting fewer than 4,000 people in the United States per year, the agency said Friday in a release.
The IBV valve, manufactured by Spiration Inc., of Redmond, Wash., is inserted through a bronchoscope and placed in the airway of the lung area affected by the air leak. The valve prevents air from entering the affected area but allows air and mucus to escape, the report said.
