Clinically Proven

Zeus is a non invasive airway stimulation device developed with King’s College London and Guy’s and St Thomas’ NHS Foundation Trust to improve breathing during sleep, reduce snoring and support people with obstructive sleep apnoea.

Zeus is based on more than 15 years of research into transcutaneous electrical nerve stimulation and upper airway muscle control.

THE SCIENCE

How Zeus works

  • Sleep causes airway muscles to relax

    When you fall asleep, the muscles that hold the tongue and upper airway open naturally lose tone. In many people this allows the airway to narrow or collapse, restricting airflow and creating vibration.

  • TENS activates the airway muscles

    Zeus uses low level transcutaneous electrical nerve stimulation (TENS) to gently stimulate the hypoglossal nerve and the upper airway muscles it controls. This electrical signal keeps the tongue and surrounding muscles active while you sleep, preventing them from falling back into the airway.

  • The airway stays open

    By maintaining muscle tone throughout the night, Zeus helps keep the airway open. This allows air to flow smoothly, reducing vibration, snoring, and breathing interruptions associated with airway collapse.

Patient reported outcomes

Participants reported significant improvements in how they slept and how they felt during the day when using Zeus.

Improvements in sleep and daytime wellbeing

84% of participants reported improved sleep quality, 78% reported improved daytime function, 68% reported reduced daytime sleepiness and 62% reported improved alertness while using Zeus. All changes were statistically significant with p values below 0.01.

Regulatory Pathway

Zeus has completed three independent clinical studies, including the Dorset NHS Trial, the TESLA Trial, and the TESLA Home Trial, which together demonstrated significant improvements in sleep quality, daytime function and daytime sleepiness.

Building on these results, Zeus has been selected by the National Institute for Health and Care Research to run one of the UK’s largest multi centre clinical trials in obstructive sleep apnoea.

This ongoing study is being led by Guy’s and St Thomas’ NHS Foundation Trust and King’s College London and will evaluate Zeus in 184 patients over 36 months in real world NHS settings.

The data from this NIHR funded trial, together with the Dorset, TESLA and TESLA Home studies, will support the regulatory submission for the ZeusOSA medical device and potential future NHS adoption.

Trusted by UK Sleep Experts

"The Zeus sleep device is simple to use and surprisingly comfortable, I barely noticed it even on the first night. As an NHS Clinical Scientist with a PhD in Respiratory Physiology, I’ve been following the development of upper airway stimulation for 15 years. It is exciting to see such a well-designed and effective solution for snoring that is grounded in strong scientific research."

Dr.Harry Griffin Lead Respiratory and Sleep Physiologist, Hampshire Hospitals NHS Foundation Trust

"Zeus is lightweight, portable and comfortable to wear. It uses TENs technology to strengthen the muscles, showing reducing snoring and providing the user an alternative to often painful and invasive treatments."

David Walker ENT Consultant, Nuffield Health

"Unlike implanted hypoglossal nerve stimulators, the Zeus device doesn’t rely on strong muscle contractions that may disturb sleep. This makes Zeus a comfortable, non-invasive alternative to surgery, while still addressing the root cause of snoring."
