What Pulmonx Corp does

In the company’s own words

Pulmonx Corporation (Nasdaq: LUNG) is a commercial-stage medical technology company focused on minimally invasive treatment for patients with severe emphysema, a form of chronic obstructive pulmonary disease. Its principal product is the Zephyr Endobronchial Valve, implanted through a bronchoscope to reduce lung hyperinflation in selected patients. The treatment process uses the Chartis Pulmonary Assessment System to assess collateral ventilation and the cloud-based LungTraX Platform to analyze lung CT scans and help physicians identify and plan treatment for candidates. Pulmonx sells primarily to hospitals, where interventional pulmonologists perform the procedures, using a direct sales organization in the United States and a mix of direct sales and distributors internationally. It also manufactures the AeriSeal System, a foam designed to close collateral air channels that is undergoing clinical development for the U.S. market. Pulmonx generated $90.5 million in revenue for fiscal 2025, primarily from Zephyr Valves and delivery catheters, with smaller contributions from Chartis and LungTraX.
