Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to assess the long-term safety of the Genio® system in adult OSA patients with and without complete concentric collapse of the soft palate who have successfully been implanted with the Genio IS in a Nyxoah sponsored Clinical Investigation.

(Serious) Adverse Device Effects and Device Deficiencies in subjects previously implanted with a Nyxoah Genio implantable stimulator (IS) and having the IS still in-situ (with therapy activated or deactivated) will be collected.

The main question it aims to answer is: what is the long term safety profile of the Genio System?

Participants will be asked to refer back to the site per standard of care and report on any (Serious) Adverse Device Effects and Device Deficiencies that may have occurred.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The objective of this study is to assess the long-term safety of the Genio® system in adult OSA patients with and without complete concentric collapse of the soft palate who have successfully been implanted with the Genio IS in a Nyxoah sponsored Clinical Investigation.

All subjects that have previously participated in a Nyxoah sponsored clinical investigation in Australia, and who are currently still implanted with an implantable stimulator (with therapy activated or de-activated) will be asked to participate in this long-term safety follow-up study and will be asked to report any (Serious) Adverse Device Effects and Device Deficiencies that may have occurred.

OLE Subjects

adult OSA patients with and without complete concentric collapse of the soft palate who have successfully been implanted with the Genio IS in a Nyxoah sponsored Clinical Investigation and having the device in-situ at the time of enrollment (with therapy activated or de-activated).

Genio System

Intervention Type DEVICE

All participants have previously been implanted with a Genio® system implantable stimulator. This research is observational in nature (long term safety follow-up) and participants will not be exposed to additional procedures.

The Genio System comprises of a bilateral Implantable Stimulator (IS), which is implanted via a minimally invasive surgery procedure and positioned over the genioglossus muscle with its electrodes positioned over both the left and right hypoglossal nerve branches. Stimulation of the hypoglossal nerve causes the tongue muscles to contract with the intention to maintain an open airway. The Implantable Stimulator receives energy pulses transmitted via the DP placed under the patient's chin and connected to the Activation Chip (AC), which contains the patient's stimulation parameters and contain a battery that provides energy.
