Description of intervention(s) / exposure
Treatment: Devices - Genio(TM) bilateral hypoglossal nerve stimulation system

Experimental: Genio(TM) system therapy - Genio(TM) bilateral hypoglossal nerve stimulation system


Treatment: Devices: Genio(TM) bilateral hypoglossal nerve stimulation system
Subjects will be consented, enrolled and eligibility criteria checked. If the subject is eligible, subject will proceed with the Genio(TM) implant implantation. Six (6) weeks after implantation, the implant will be activated and the subject will be assessed at 1 month plus 1 week, 2, 3, 4, 5 and 6 month(s) after implantation

Summary
Brief summary
The objective of this study is to explore the safety and performance of the Genio™ system in
adult obstructive sleep apnoea (OSA) patients with and without complete concentric collapse
of the soft palate over a period of 4.5 months of treatment (i.e. 6 months post-surgery)
measured by the AHI, at rest to determine if there is a difference in performance between the
two populations.
