Valvular Bronchoblocation (VB)


Promising new approach for both acute and chronic conditions of the lung and for treating diseased lung in emphysematous patients or damaged lung resulting in air leaks. The valve is a device placed in selected lung airways and limits the airflow to the occluded areas of the lung while still allowing mucus and trapped air to pass by outside of the valve in proximal direction. For the treatment of air leaks, the valve limits airflow to injured tissue. Prolonged post-surgery, persistent as well as spontaneous secondary air leaks have been treated successfully. Published case reports showed a 94% success rate of treatment of prolonged air leaks. For the treatment of emphysema, the valves allow total occlusion of single lobes with atelectasis.
