Inspire surgery takes about 3 hours from start to finish. It’s typically an outpatient procedure, meaning most people go home the same day and manage any discomfort with over-the-counter pain medication.
What Happens During the Procedure
Inspire is a small implanted device that treats obstructive sleep apnea by stimulating the nerve that controls your tongue. During sleep, it gently moves your tongue forward to keep your airway open, eliminating the need for a CPAP mask. The surgery to place it requires general anesthesia and involves three small incisions.
The first incision, about 2 inches long, is made under the jawline on the right side. This is where the surgeon attaches a small lead to the nerve that controls tongue movement. The second incision, also about 2 inches, goes just below the right collarbone. This is where the pulse generator (the main device, similar in size to a pacemaker) is placed in a small pocket under the skin. The third incision is made along the right side of the chest, between the ribs. A sensing lead placed here detects your breathing pattern so the device knows when to activate.
The three components are connected by thin wires tunneled under the skin. In some cases, your surgeon may recommend staying one night in the hospital, but same-day discharge is the norm.
Recovery and Activation Timeline
The surgery itself is the shorter part of the process. What surprises many people is that the device isn’t turned on right away. You’ll need to wait roughly one month after surgery before your doctor activates the Inspire system. This healing period gives the incision sites time to close and the leads time to settle into position.
During recovery, you’ll have lifting and physical activity restrictions to protect the incisions and prevent the leads from shifting. Most people return to desk work and light daily activities within a week or so, though strenuous exercise and heavy lifting are off-limits for several weeks. Your surgical team will give you a specific timeline based on how your healing progresses.
Once the device is activated, you’ll visit your doctor for a titration session where the stimulation settings are adjusted to find the right level for you. This process may take a few visits. You control the device each night with a small handheld remote, turning it on before bed and off when you wake up.
Who Qualifies for Inspire
Inspire isn’t a first-line treatment. It’s designed for people with moderate to severe obstructive sleep apnea who can’t tolerate or get consistent results from CPAP therapy. The standard eligibility window is an AHI (the number of breathing disruptions per hour of sleep) between 15 and 65, with a BMI at or below 32. More recently, the FDA has expanded approval to include patients with higher severity: AHI up to 100 and BMI up to 40.
Before being approved for surgery, you’ll also need a drug-induced sleep endoscopy. This is a brief procedure where a doctor uses a small camera to watch how your airway collapses while you’re sedated. Inspire works best when the airway closes in a front-to-back pattern. If it collapses in a circular or side-to-side pattern, the device is less likely to help, and you may not be a candidate.
How Well It Works
FDA data from over 1,100 patients shows that about 64% of people with typical sleep apnea severity (AHI of 65 or below) meet the clinical definition of a successful response. On average, these patients saw their AHI drop by about 19 events per hour. For people with more severe apnea (AHI between 65 and 100), the response rate was similar at roughly 67%, with an average AHI reduction of about 55 events per hour, reflecting their higher starting point.
These numbers mean Inspire significantly reduces sleep apnea events for most people, but it doesn’t eliminate them entirely for everyone. Some patients see dramatic improvement, while others get a more modest benefit. BMI doesn’t appear to make a major difference in outcomes: response rates were 65% for patients with a BMI of 32 or below and 61% for those in the 32 to 40 range.
Battery Life and Long-Term Upkeep
The pulse generator runs on an internal battery that lasts around 10 years. When the battery eventually depletes, a shorter replacement surgery is needed to swap out the generator. The leads typically stay in place and don’t need to be replaced, so the second procedure is less involved than the original implantation. Beyond battery replacement, the device requires periodic check-ups to ensure the settings are still optimized as your body and sleep patterns change over time.
