How does it work?

Redirecting Airflow

The IBV Valve is a small, umbrella-shaped, one-way valve that is placed inside the airways of a lung. It is used to redirect air from the less healthy to the more healthy parts of the lung.

Redirecting air away from the diseased parts of the lung may reduce over-inflation while letting trapped air and fluids escape. The volume of the treated part of the lung may be reduced, allowing healthier parts of the lung to expand and function more normally. This may help reduce over-inflation and may improve overall lung function and quality of life for people living with COPD or emphysema.

After the procedure, your trial doctor will require you to stay in the hospital for a minimum of one night. Although the valves are meant to be permanent, they are designed to be removable.

Not all patients will benefit from the procedure and there are some significant risks. Potential benefits and risks will be reviewed with all eligible patients by the trial doctor and a member of the trial support team.

The IBV Valve Procedure

1

Surgery is not needed to place valves in the airways of the lung. The IBV Valves are placed using a tool called a bronchoscope, which is a flexible tube with a camera at the end.

2

The valve is placed in the airway using a catheter that goes down the bronchoscope. Once the valve is in the airway, it expands and contracts with breathing.

3

More than one valve will be placed. The valve allows trapped air and fluids to flow past it, but blocks air from entering the diseased part of the lung.

4

The valve redirects air to healthier parts of the lung and may reduce over-inflation.
