Sells Zephyr endobronchial valves, delivery catheters, Chartis assessment tools, and LungTraX planning services for severe emphysema care. Revenue is concentrated in valve procedures, sold mainly through direct teams, with adoption shaped by physician training, patient selection, reimbursement, procedure risk, and device approvals.
Centers on the Zephyr Endobronchial Valve, Chartis Pulmonary Assessment System, and LungTraX planning platform for severe emphysema patients who remain highly symptomatic after medical management. The workflow uses bronchoscopic valve implants, collateral-ventilation assessment, and CT-based planning to select patients likely to respond.
Sells mainly to hospitals and distributors through a direct U.S. organization and a mix of direct teams and distributors overseas. Zephyr valves and delivery catheters provide most revenue, with Chartis and LungTraX supporting procedure adoption.
Execution depends on clinical evidence, physician training, hospital access, reimbursement, manufacturing, and regulatory approvals. AeriSeal is not approved for U.S. commercial sale and remains tied to clinical-trial progress. Procedure adoption is shaped by patient-selection discipline and complications such as pneumothorax.
