Pulmonx Corporation

Pulmonx makes medical devices to treat severe emphysema, a lung disease that makes it hard to breathe. Their main product is the Zephyr Endobronchial Valve, a small device placed inside airways to help patients breathe better without open surgery. The company also sells the Chartis system, which doctors use to test lungs before treatment, and LungTraX, a cloud-based software that analyzes lung scans to help doctors plan treatment for individual patients. Pulmonx sells these products to hospitals and clinics in the United States and around the world.
