CSA Medical is a medical technology company developing the RejuvenAir System, a minimally invasive liquid nitrogen spray cryotherapy device for treating chronic bronchitis in COPD patients.[1][2][3] It targets damaged airway cells causing mucus overproduction and dysfunctional cilia, flash-freezing them to enable regrowth of healthy tissue without scarring, serving pulmonologists and patients underserved by existing drugs or devices.[2][3][5] The company, founded in 1993 and based in Lexington, Massachusetts, has raised significant funding, including a $53 million oversubscribed Series D in 2021 led by TVM Capital Life Science and Yonjin Ventures, to support FDA approval and U.S. commercialization; it holds EU approval and is under U.S. clinical investigation.[1][3][5]
CSA Medical was founded in 1993 in Lexington, Massachusetts, initially focusing on spray cryotherapy platforms using liquid nitrogen to ablate unwanted tissue.[1][4] Key leadership includes CEO Wendelin Maners and scientific advisor Dr. Luc Marengère, with board additions from investors like TVM Capital.[2][5] Early milestones include FDA clearance in 2017 for its truFreeze system to treat Barrett’s esophagus with high-grade dysplasia, building on prior use since 2006 and demonstrating high ablation rates (87% CE-D).[4] This foundation evolved into the RejuvenAir System for respiratory applications, with pivotal clinical trials (NCT03893370, NCT03892694) and recent 2024 data at the European Respiratory Society Congress showing airway remodeling and quality-of-life improvements.[3][6]
CSA Medical rides the wave of precision respiratory therapies amid rising COPD prevalence (affecting millions globally, with chronic bronchitis as a key driver), where current treatments like bronchodilators or stents fail to reverse underlying pathology.[1][2][5] Timing aligns with advances in minimally invasive bronchoscopy and cryotherapy adoption, fueled by post-pandemic focus on lung health and aging populations; market forces include a $10B+ COPD device sector and unmet need for disease-modifying options.[5][6] By pioneering airway cryospray, it influences medtech ecosystems, potentially expanding to other respiratory indications and setting standards for tissue regeneration via cryotherapy.[4][6]
CSA Medical nears U.S. FDA premarket approval submission for RejuvenAir post-pivotal trials, with 2024 data strengthening its case for chronic bronchitis approval and global launch.[3][5][6] Trends like AI-driven dosimetry refinements, combination therapies with biologics, and bronchoscopic innovations will shape its path, amplifying impact in underserved COPD care. Its influence could grow by dominating cryotherapy in pulmonology, much like truFreeze did in GI, transforming lives through true disease modification.[4][6] This positions CSA Medical as a leader in regenerative respiratory tech, directly advancing its mission to rejuvenate lungs for millions.
CSA Medical has raised $135.0M across 4 funding rounds. Most recently, it raised $53.0M Series D in September 2024.
