Itamar Medical produces affordable devices for diagnosing sleep-related breathing disorders at a person's own home, allowing them to avoid having to visit costly and prohibitively unwieldy sleep labs. In 2016, the U.S. Food and Drug Administration granted approval for the company’s wristwatch-like WatchPAT apnea-detection device for adolescent use. Itamar Medical also launched a WatchPAT that combines a chest detector that examines snoring and body positions, meaning that it can detect detailed breathing patterns that characterize patients with potential heart failure. The devices are sold to cardiologists and other doctors, who provide them to patients—to date, 1.2 million people have used them. Also, in 2016, the company signed a distribution deal with DeVilbiss Healthcare, a major manufacturer of positive airway pressure (PAP) masks, to provide a comprehensive sleep apnea-management solution (diagnostic, cloud-based remote interpretation and therapy) to cardiology practices and their patients.
