Spirair develops minimally invasive ENT medical devices. The flagship SeptAlign system uses a bioabsorbable implant to mechanically straighten minor nasal septal deviations through an in-office procedure that can be done with local anesthesia; the implant dissolves in about six months after the cartilage maintains its new shape. In 2025, Spirair added TurbAlign, a bioabsorbable implant designed to separate the middle turbinate from the nasal wall to aid healing after sinus surgery. The devices are sold to ENT doctors and designed to preserve tissue and shorten recovery compared with traditional septoplasty, aiming to improve nasal airflow and expand access to less invasive nasal correction.
