The IBV Valve is an umbrella-shaped, one way valve that is placed via a delivery catheter, introduced through the working channel of a flexible bronchoscope.
The valve consists of a Nitinol frame covered with a polymer membrane and five anchors that securely engage the airway walls at the targeted treatment location.
Once in place, the spiration valve limits airflow to damaged tissue while allowing trapped air and fluid to escape. Complete occlusion of a targeted lobe by the valves may enable significant lobar volume reduction, relieving hyperinflation and allowing the patient to breathe easier. 1,2
The first and only valve with anchors for 0% migration and expectoration. 3, 4, 5
The first and only valve with a nitinol umbrella like frame, designed to minimise contact with the bronchial wall and conform to complex airways.
The first and only valve without a pressure fit, allowing secretions to escape naturally along the bronchial wall.
The first and only valve with a centre rod to facilitate removal.
The first and only valve system complatible with a 2.0 mm instrument channel for greater airway access.
