Three Key Takeaways:
- Defect and Recall: Inspire Medical Systems is recalling the Inspire IV implantable pulse generator due to a manufacturing defect that can cause electrical malfunctions, leading to potential serious health risks.
- Patient and Provider Actions: Affected patients are advised to contact their healthcare providers for routine check-ups and possible revision surgery, while providers are urged to notify patients and monitor the devices closely.
- FDA Classification: The FDA has identified this recall as the most serious type, indicating that the defect could result in severe injury or death if not addressed.
Inspire Medical Systems is recalling Inspire IV implantable pulse generator model 3028, a key component of the Inspire upper airway stimulation system for treating obstructive sleep apnea, due to a manufacturing defect.
This defect can cause system malfunctions after implantation, leading to electrical leakage in the sensing circuit. As a result, patients may need revision surgery to replace the implantable pulse generator and restore therapy.
The use of the affected product may cause serious adverse health consequences, including stimulation below normal therapeutic levels and/or early depletion of the battery (resulting in loss of therapy), inappropriate or inconsistent stimulation effect, painful stimulation, or perceived shocking sensation and death.
There have been no reported injuries or death deaths, according to a medical device recall notice from the US Food and Drug Administration (FDA).
The implantable pulse generator stores therapy settings configured by a physician and delivers mild electrical stimulation to the hypoglossal nerve, which controls tongue muscles, to maintain airway patency during sleep. The implantable pulse generator works together with external programmers that allow the physician to set and adjust the therapy parameters and the patient to control the therapy’s activation and intensity.
This recall involves removing certain devices from where they are used or sold. The FDA has identified this recall as the most serious type. This device may cause serious injury or death.

What to Do
On June 17, Inspire Medical sent all affected customers an Urgent Medical Device Correction recommending the following actions:
Healthcare Providers:
- Notify affected patients of this voluntary recall.
- Schedule an appointment for the patient to check if their Inspire therapy is working properly by analyzing signals and resistance. Keep an eye out for any changes in the stimulation, lack of therapy effectiveness, or problems with turning the therapy on.
- Keep doing regular check-ups and tests to analyze signals and resistance at every visit, as these simple tests can spot issues with the device without needing surgery.
Patients:
- Contact your healthcare provider as soon as possible to make sure you have a routine office visit scheduled.
- If you have already been contacted by your healthcare provider, follow up as scheduled.
- Attend your scheduled office visit. Routine non-invasive diagnostic monitoring identifies this potential implantable pulse generator defect.
- If you have new symptoms or re-occurrence of symptoms like fatigue, perceived sleepiness, snoring problems, etc, contact your sleep physician for a comprehensive evaluation, which may include a polysomnography.
- If your provider determines a revision surgery is necessary to replace the implantable pulse generator, you may contact Inspire’s Patient and Physician Services at 1-844-OSA-HELP (1-844-672-4357) for further information.
