CSA Medical, Inc.
CSA Medical is a Lexington, Massachusetts medical device company that develops spray cryotherapy technology for the lungs. Its flagship RejuvenAir System delivers a metered dose of -196°C liquid nitrogen through a bronchoscope to destroy the damaged, mucus-producing cells that drive chronic bronchitis in COPD patients, while preserving the underlying tissue matrix so healthy airway cells can regrow. Backed by roughly $161M in total funding including a $53M Series D in 2024, the company submitted its FDA PMA in January 2026 following a successful pivotal SPRAY-CB trial.
