This trial is studying the Spiration Valve System, a medical device that has already been approved by the FDA, in real-world patients with severe emphysema. Researchers want to confirm that this treatment is safe and effective over a three-year period in everyday clinical practice. The valve is designed to help people with severe emphysema breathe more easily by reducing air trapping in the lungs.
Although this device has been approved by regulators, the company wants to continue gathering evidence about how well it works and how safe it is when used in different patient populations. This registry-style study helps ensure the treatment remains effective and safe for people who receive it.

If you join, you will receive the valve implant procedure and then return for follow-up visits over three years. During this time, researchers will monitor your breathing, lung function, quality of life, and any side effects to make sure the treatment is working safely. You will share your health information and complete routine tests at baseline and at regular intervals throughout the three-year period.
