Janus II: dual-channel implant for severe sleep apnea
Official title: Janus II: A Feasibility Study to Evaluate Response to Remede Dual Channel System Therapy
Run by Zoll Medical Corporation · NCT06556693 · Data updated 2026-11-12
This study will test a dual-channel implant (remedē® Dual Channel System) in adults with severe sleep apnea to see if it can be implanted safely and improve breathing during sleep.

Is this trial a fit for you?
✓Likely a good fit
Adults with severe sleep-disordered breathing who can tolerate an implant procedure and do not have exclusionary conditions such as uncontrolled COPD, pacemaker dependence, recent infection, need for MRI, or prior cervical surgery/radiation are the ideal candidates.
✕Probably not a fit
Patients with contraindications listed in the protocol — for example pacemaker dependence, severe COPD or pulmonary hypertension, active infection within 30 days, significant kidney failure, or a need for MRI — are unlikely to be eligible or to receive benefit from participation.

What this trial studies
This is an interventional feasibility study of the remedē® Dual Channel System that involves surgical implant of a dual-channel neurostimulation device and overnight sleep studies. Participants with severe sleep-disordered breathing who can tolerate the procedures will receive the implant and undergo scheduled overnight assessments to monitor device performance and sleep measures. The study will also track participants over time to collect data on chronic safety and any device-related adverse events. Many common exclusions apply (for example severe COPD, pacemaker dependence, recent infection, need for MRI, prior neck surgery/radiation) that limit eligibility.
Why it matters
Potential benefit: If successful, the device could provide a new implantable option to reduce breathing pauses and improve sleep quality for people with severe sleep apnea.
How similar studies have gone: Implantable neurostimulation systems for sleep apnea, including earlier remedē devices for central sleep apnea, have demonstrated clinical benefit in prior studies, though the dual-channel configuration used here is less well established and is being tested for feasibility.
