It is probably "Inspire is an implantable device that treats obstructive sleep apnea by stimulating the tongue nerve to keep airways open during sleep. It's an option for people who have moderate or severe sleep apnea and can't use or don't benefit from a CPAP machine.

Here's how Inspire works: Components: The device consists of a generator, sensing lead, and stimulation lead, all implanted under the skin. It also includes a handheld remote that patients use to turn the device on and off, adjust stimulation strength, and pause it during the night. How it works: When the sensing lead detects breathing, the generator sends a signal to the stimulation lead, which then stimulates the hypoglossal nerve. This causes the tongue to move slightly forward, which helps keep the airways open. FDA approval: The FDA approved Inspire in 2014.

Some potential side effects of Inspire include: Damage to blood vessels near the implant, Excessive bleeding, and Nerve trauma or damage"

There's a reason it hasn't taken off in 10 years.
