Battery-Free Stimulator
Placed under the chin during an outpatient procedure, the implant delivers stimulation to the hypoglossal nerves. It is powered by the external wearable rather than an implanted battery.

A mask-free, FDA-approved treatment option for eligible adults with moderate-to-severe obstructive sleep apnea. Genio stimulates nerves on both sides of the tongue to help keep the airway open during sleep.
Genio combines a battery-free implanted stimulator with an external sleep wearable. The stimulator is placed under the chin during an outpatient surgical procedure.
The wearable includes a disposable patch and an external battery, called the activation chip. Worn under the chin at night, it supplies power to the implant.
Activation is typically planned approximately eight weeks after the procedure, with timing confirmed by your treating team. An optional smartphone app supports usage tracking and adjustments within a predefined range.
The activation chip is charged daily using a small portable charger, including when traveling. Houston Sleep Health can guide your evaluation and discuss next steps with appropriate ENT specialists and surgeons.
Discuss Genio therapyA battery-free stimulator and an externally powered wearable work together to deliver your prescribed therapy.
Genio stimulates the hypoglossal nerves on both sides of the tongue. This activates tongue muscles to help maintain an open airway during sleep.
Your system includes the implant, sleep wearable, disposable patch, external activation chip, and optional smartphone app.
Learn about your optionsIf you qualify, the battery-free stimulator is placed under the chin during an outpatient surgical procedure.
Therapy is typically activated approximately eight weeks after the procedure. Your treating team determines the timing and settings.
The disposable patch and activation chip are worn under the chin to power stimulation while you sleep.
Recharge the activation chip daily. The optional app tracks use and allows adjustments within your prescribed range.
Clinical research has reported reductions in sleep apnea events with bilateral hypoglossal nerve stimulation, alongside high rates of daily use and patient satisfaction.
Results vary from person to person. An evaluation and ongoing follow-up help determine whether treatment is appropriate and how well it is working for you.

The study used the first-generation Genio implant. The U.S. model includes FDA-approved design enhancements.
Genio may be appropriate for selected adults with moderate-to-severe obstructive sleep apnea. Your sleep specialist reviews your diagnosis, prior treatments, anatomy, and health history.
BMI and other medical factors are assessed alongside device labeling and insurance requirements. These points are a starting point for evaluation, not confirmation of eligibility.

Ask our teamGenio is an FDA-approved implantable treatment for selected adults with moderate-to-severe obstructive sleep apnea. It uses a battery-free implanted stimulator powered by a wearable beneath the chin.
It stimulates the hypoglossal nerves on both sides of the tongue. The resulting muscle activity helps keep the upper airway open while you sleep.
Yes. The FDA approved the Genio System 2.1 in August 2025 for a defined group of adults with moderate-to-severe OSA. A clinical evaluation is needed to confirm eligibility.
Yes. The battery-free stimulator is implanted under the chin during an outpatient surgical procedure. Your surgeon will discuss risks, recovery, and follow-up.
Candidates are adults age 22 or older with OSA and an AHI of 15–65 whose standard treatment options have failed, are not tolerated, or are unsuitable. Your team also reviews anatomy, BMI, medical history, and other device-specific requirements.
Activation is typically planned approximately eight weeks after implantation. Your treating team confirms the timing based on your recovery and care plan.
An optional app supports device usage tracking and therapy adjustments within a predefined range. Your care team explains how to use it with your prescribed settings.
