Vapotherm Inc. Which Specializes in Developing Humidification Systems, Raises $26.4 Million

A medical device manufacturer that has specialized in developing humidification systems to improve breathing for people with respiratory difficulties such as asthma, croup and COPD has raised $26.4 million, according to a Form D filing with the U.S. Securities and Exchange Commission. Last year, Vapotherm, which has offices in Stevensville, Maryland, said it would expand to Exeter, New Hampshire. It received 510(k) clearance from the U.S. Food and Drug Administration two years ago for its Precision Flow Heliox device — a high-flow humidification system designed for use with blended helium oxygen gas mixtures or Heliox. Heliox is used in respiratory applications such as upper airway obstruction, asthma, croup and COPD.
