The company's technology includes Hemolung, an extracorporeal gas exchange device that circulates blood through a small catheter, and Hattler Catheter, which is placed within the central venous bloodstream. Their Hemolung Respiratory Assist System (RAS) is a dialysis-like alternative to mechanical ventilation that removes carbon dioxide from the blood, allowing the patient's lungs to rest and heal. ALung Technologies was founded in 1997 and is headquartered in Pittsburgh, Pennsylvania. They are now part of LivaNova.
