Non-invasive medical device for the treatment of sleep apnea

L'innovation

The invention relates to a new monitoring and treatment device for obstructive sleep apnea syndrome (OSA).
It is the first Proof of concept identifying kinesthetic stimulation as a potentially effective therapy for OSA.
The sleep apnea medical devices market will reach 6.5B€ in 2023, with a 8% CAGR for therapeutic devices (representing more than 80% of the market).

The system is composed of 3 components:
- a cardio-respiratory recorder,
- a kinesthetic stimulator
- and a real-time processing application, integrating an “on-off” control method to trigger the kinesthetic stimulation as a function of respiratory event detection of a given patient.

Ses bénéfices
The device is not cumbersome and easy to wear
75% of the patients showed a statistically significant decrease in apnea or hypopnea event durations in the first clinical evaluation.
Average reduction in the duration of StimOn vs StimOff events for the patients who presented a significant response is : 4.86 seconds (25.48%) for apneas and 6.00 seconds (23.92%) for hypopneas

Ses applications
This project concerns a new device for Obstructive Sleep Apnea (OSA) treatment.
This pathology concerns 8-15% of general population and is an important risk factor for hypertension, coronary heart diseases and strokes.
