About Signifier Medical Technologies
Signifier Medical Technologies is a medical technology company focused on the development and commercialization of innovative and non-invasive solutions for patients with sleep-disordered breathing conditions and snoring.
Signifier’s proprietary therapy eXciteOSA® is the first and only daytime genioglossal (tongue) muscle-neurostimulation technology for mild obstructive sleep apnea and snoring, supported by clinical data from prestigious and well-recognized universities and academic institutions, that provides a safe and effective treatment for its patients.1-3
About OSA and Snoring
Nearly 1 billion adults aged 30 to 69 years are estimated to have obstructive sleep apnea (OSA) globally. There is a strong, clinically proven link between OSA and co-morbidities like diabetes, hypertension, and strokes. Mild OSA affects over 110 million people in the US and 100 million people in Europe.
Obstructive sleep apnea is marked by the recurring collapse of the upper airways during sleep. The most common symptoms are restless sleep, snoring, tiredness during the day, decreased intellectual alertness, and personality alterations. Higher risks of cardiovascular diseases and increased mortality rates have been associated with OSA.
Standard therapy of all advanced levels of sleep apnea is with a continuous positive airway pressure (CPAP) device. Many patients find this therapy invasive, and the long-term compliance of CPAP therapy is limited, so there is a clear demand for new forms of treatment.

Clinical study of 115 patients with snoring or mild OSA (Apnea- Hypopnea Index (AHI <15 n=65). Objective snoring and respiratory parameters were recorded with 2 consecutive WatchPat night sleep studies before and after the use of the device. An intra-oral tongue stimulator (Snoozeal®) device was used for 20mins, once a day for 6-week period
