The AeriSeal, a polymer foam designed to help treat emphysema, is undergoing its first US late-stage clinical trials.
The AeriSeal system, which is used to reduce lung volume in patients with severe emphysema, has already been approved in Isreal and parts of Europe. Emphysema affects the patient by causing the air sacs in the lung to fill with air the body cannot exhale, resulting in pressure on the diaphragm and making breathing difficult.
The AeriSeal is offered as an alternative to surgery, and is performed by a standard bronchoscopy, by which a catheter is fed to the most affected part of the lung. The propriety polymer foam consists of two liquid parts that are mixed together with air just before injection on the site, where it hardens within a half-hour to a stiff rubber that blocks off the holes in the air sacs of the damaged regions. As the air sacs deflate, the lung shrinks, removing the pressure from the diaphragm.
