How I Explain Inspire to My Patients

Dr. Ryan Nord holds an Inspire pulse generator, the implantable device used in hypoglossal nerve stimulation therapy for obstructive sleep apnea.

Inspire is like a pacemaker for your breathing. It’s placed through two small incisions — one in your neck and one in your chest, both on the right side. Through the neck incision, we place a small stimulation cuff around the nerve that controls your tongue. We then tunnel a wire down to the chest, where it connects to the battery that powers the device.

The battery lasts about eleven years and never needs to be recharged. The surgery takes roughly an hour, and it’s outpatient — you go home the same day.

About a month later, once you’re fully healed, we activate the device in the office. You’re given a small remote and taught how to use it. At bedtime, you press a button to turn the device on. It pulses once to let you know it’s working, then delays about thirty minutes so you can fall asleep.

Once the therapy kicks in, Inspire senses your breathing with every breath and gently pulses your tongue forward to keep your airway open. This typically reduces sleep apnea by about 70%. You’ll come in about twice a year to have the device checked, and we’ll do a home sleep study three to four months after surgery to confirm everything is working well.

What’s Actually Being Implanted?

The current generation of Inspire (Inspire V) has just two components, all hidden beneath the skin.

What Does Recovery Look Like?

Most patients are surprised by how manageable the recovery is. The device stays off during the entire healing period — there's no rush.

Surgery Day

~1 hour, outpatient.
Go home same day.

Days 1–3

Most soreness.
OTC pain meds enough.

Weeks 1–2

Feeling significantly better; light activity.

Weeks 2–4

Resume normal activity.
Device stays OFF.

Activation Day!

1 Month

Device turned on.
Remote training.

Sleep study at 3–4 months confirms therapy is working

How Inspire Compares to Traditional Sleep Surgery

Inspire doesn’t change your anatomy — it works with your anatomy. Unlike traditional tissue-removing surgeries, the therapy is adjustable and reversible.

Traditional Surgery (UPPP)

Cuts and Restructures Tissue

Approach
Removes / rearranges tissue
Success Rate
~50%
Reversible?
No — permanent changes
Adjustable?
No
Side Effects
Permanent swallowing, voice, and taste changes
Readmission
Higher complication rate
Inspire Therapy

Works With Your Anatomy

Approach
Stimulates existing nerve
Success Rate
68%
Reversible?
Yes — can be removed
Adjustable?
Yes — settings tuned over time
Side Effects
Temporary soreness, much lower complication rate
Readmission
Significantly lower

Living with Inspire

Once you’re up and running, the nightly routine is simple. Press a button at bedtime. Turn it off in the morning. That’s it.

Nightly Routine
Press the button on your remote at bedtime. Turn it off in the morning. That’s it.
Office Visits
About twice a year for a device check and settings tune-up. We review your usage data and adjust as needed.
Battery Life
Lasts approximately 11 years. No recharging needed. Quick outpatient swap when it runs low.
Inspire is MR conditional, and what’s allowed depends on your device model. Inspire IV and Inspire V systems are approved for full-body MRI at 1.5T and — as of February 2026 — 3T, under specific scan conditions (coil type, positioning, and parameters). Some earlier-generation devices are more limited, and the oldest model (3024) cannot have an MRI at all. You’ll receive an Inspire patient ID card — show it to the radiology team before any scan so they can confirm your exact model and its conditions.

Always consult with your physician to determine the best treatment option for your individual needs.

What Inspire Surgery Actually Looks Like

Reading about the procedure is one thing — seeing it is another. This is footage from an Inspire implant I performed, showing the part of the operation patients ask about most: the small incision in the neck, finding the hypoglossal nerve, and placing the stimulation cuff around it.

Viewer note: this is real operative footage. If you would rather not watch surgery, everything shown here is also explained in words above.

Risks and complications — the honest version

Every surgery has risks, and researching Inspire’s complications — so I can prevent them — has been a focus of my career. The short version:

  • Serious events are uncommon — under 2% in the pivotal trial’s first year.
  • In my own published research, Inspire patients had a 2.3% complication rate within 90 days versus 20.1% for traditional palate surgery.
  • The risks worth understanding in detail: bleeding, infection (~0.5–1.4% in published series), temporary tongue or lip weakness, neck tightness from the connecting wire, rare hardware problems — and the honest truth that Inspire is not a guaranteed cure.

When an implant isn’t the right choice

I implant both Inspire and Genio, and I tell patients straight: an implant is not always the answer. Some people get a better, safer, more durable result from something else. Here are the situations where I steer the conversation in a different direction.

Complete concentric collapse at the soft palate

If drug-induced sleep endoscopy (DISE) shows the soft palate collapsing inward from all sides simultaneously (complete concentric collapse, or CCC), Inspire is not approved and tends not to work well. Genio may still be an option in some of these cases; in others, a palatal procedure or a different approach makes more sense. The DISE finding matters more than the AHI here.

BMI above the labeled cutoff

Both implants have BMI ranges in their FDA labeling. Patients well above those ranges have lower success rates in the trial data and in real-world registries. If you’re close to the cutoff, modest weight loss before surgery often changes the equation; if you’re well above it, weight management or bariatric evaluation typically deserves the first attempt. Not sure where you stand? Check your BMI here.

Central or mixed apnea predominant

Hypoglossal nerve stimulation treats obstructive events — the airway physically closing. If your sleep study shows that most of your events are central (the brain not signaling the breath) or that you have significant treatment-emergent central apnea, an implant won’t address the underlying problem. Bilevel ventilation (BiPAP, ASV) or other strategies are usually a better fit.

A real CPAP trial hasn’t happened yet

CPAP is the most effective, safest, and least expensive sleep apnea treatment we have. Before considering surgery, I want to know that you’ve had a serious attempt — different masks, humidification, pressure adjustments, sometimes a switch to BiPAP. Patients who get to surgery without a real CPAP trial often have unrealistic expectations of what an implant will deliver. See: Failing CPAP — when sleep surgery is worth considering.

Anatomy that points elsewhere

Sometimes DISE reveals patterns that suggest a more targeted procedure will help more than an implant — a deviated septum, large tonsils, a long soft palate, or specific lateral wall collapse. In those cases, a traditional sleep surgery (or staged approach) may give a better result. The point of the workup is to find the path that fits your anatomy, not to fit you to a device.

What I tell patients

An implant is a good answer for the right patient. It is not the only answer, and it is not always the best answer. The honest evaluation is the value — not the device. If you’re considering Inspire or Genio, the goal of the consultation is to figure out whether either one is the right fit for you, and to be honest about it if neither one is.

STAR Trial (Strollo PJ Jr et al., NEJM 2014)

The pivotal trial that led to FDA approval of Inspire upper-airway stimulation. At 12 months, the apnea–hypopnea index fell 68% and oxygen desaturation events fell 70%, with sustained improvements in daytime sleepiness and quality of life.

N Engl J Med. 2014;370(2):139–149. doi:10.1056/NEJMoa1308659

STAR Five-Year Follow-Up (Woodson BT et al., Otolaryngol Head Neck Surg 2018)

Long-term outcomes confirmed durability: AHI reduction, oxygenation, and daytime sleepiness improvements were maintained at five years, with sustained patient satisfaction and quality-of-life gains.

Otolaryngol Head Neck Surg. 2018;159(1):194–202. doi:10.1177/0194599818762383

ADHERE Registry (Heiser C et al., Eur Respir J 2019; Mehra R et al., Otolaryngol Head Neck Surg 2020)

Real-world post-market data from thousands of implanted patients across multiple centers. Outcomes in the registry closely mirror the trial: roughly two-thirds of patients achieve clinically meaningful AHI reduction, with high satisfaction and low complication rates.

FDA Approval & Labeling

FDA-approved indications, BMI cutoffs, and anatomic criteria define formal candidacy. The labeling reflects the populations studied in STAR and subsequent submissions and is what U.S. surgeons use to determine eligibility.

DISE for Implant Candidacy (Kezirian EJ et al., Eur Arch Otorhinolaryngol 2011 — VOTE classification)

Drug-induced sleep endoscopy with the VOTE (Velum, Oropharynx, Tongue base, Epiglottis) classification is the standard pre-operative assessment for identifying complete concentric palatal collapse — the main contraindication to Inspire.

Common questions about Inspire

What is the Inspire implant, and how does it work?

Inspire is a small implant that gently stimulates the nerve controlling your tongue (the hypoglossal nerve) during sleep. When the device senses you breathing in, it sends a mild signal that moves the tongue slightly forward, keeping the airway open. You turn it on at bedtime with a small remote and off in the morning. It works without a mask, hose, or machine.

Who qualifies for an Inspire implant?

FDA-approved candidates have moderate-to-severe obstructive sleep apnea, have tried and not tolerated CPAP, fall within the labeled BMI range, and have an airway pattern on drug-induced sleep endoscopy (DISE) that suggests Inspire will work. Candidacy is confirmed in consultation with a sleep surgeon after a sleep study and DISE.

How long is recovery after Inspire surgery?

Most patients go home the same day. Soreness around the neck and chest incisions is typical for one to two weeks and usually managed with over-the-counter pain medication. Most people return to desk work within a few days and resume normal activity within three weeks. The device itself is not turned on until about a month after surgery, once the incisions are fully healed.

Can I feel the Inspire implant at night?

Most patients describe the stimulation as a mild, tingling sensation that fades into the background within a few nights. You can adjust the strength yourself with the remote, and a built-in pause delay lets you fall asleep before stimulation starts. The implant under the skin is rarely noticeable once healing is complete.

Can I have an MRI with Inspire?

Inspire is approved as “MR-conditional,” meaning MRIs can be performed safely under specific conditions (coil type, body region, and parameters). You’ll receive an Inspire patient ID card to show your radiologist before any MRI. Always confirm with your radiology team and your sleep surgeon’s office in advance.

How long does the Inspire battery last?

The internal battery lasts roughly eleven years on average and does not need to be recharged. When it runs low, the generator is replaced in a brief outpatient procedure — much smaller than the original surgery.

When is Inspire not the right choice?

Inspire isn’t a fit for everyone. Patients with complete concentric collapse at the soft palate on DISE, a BMI above the FDA-labeled cutoff, predominantly central (rather than obstructive) apnea, or anatomy that doesn’t match the device’s mechanism may be better served by other treatments — including continued CPAP optimization, weight management, alternative implants, or different surgical procedures. Honest evaluation of these factors is part of the consultation.
