Axonics vs. Pacemaker: Key Differences Every Patient Should Know
If you’ve been told that Axonics sacral neuromodulation therapy might help with your bladder symptoms, one of the most common questions we hear at Bladder Centers of America is: “Is this like a pacemaker?”
It’s a great question — and understanding the axonics vs pacemaker comparison can help you feel more confident about your treatment options. While both devices are small implants that use electrical signals to regulate the body, they work on completely different systems and serve entirely different purposes.
What Is an Axonics Device?
The Axonics system is a type of sacral neuromodulation (SNM) device — a small implant designed to treat bladder and bowel control conditions, including overactive bladder (OAB), urge urinary incontinence, urinary retention, and fecal incontinence in some cases.
The Axonics device is implanted near the sacral nerves in the lower back and delivers gentle, continuous electrical pulses to help restore normal communication between the brain and bladder. It is designed to last 15+ years before battery replacement is needed. Learn more about SNM therapy.
What Is a Cardiac Pacemaker?
A cardiac pacemaker is a device designed to regulate the heart’s electrical system. It is implanted in the chest and sends electrical impulses to the heart muscle to help it beat at a normal, steady rate. Pacemakers are used for bradycardia, heart block, and arrhythmias.
Axonics vs. Pacemaker: Key Differences
Despite surface similarities, the Axonics system and a cardiac pacemaker are fundamentally different.
1. What They Treat
The Axonics device treats bladder/bowel nerve signals. A pacemaker treats heart rhythm disorders. They operate on completely separate systems in the body.
2. Where They Are Implanted
Axonics: Implanted near the sacrum (tailbone area). Pacemaker: Implanted in the chest, near the collarbone.
3. Battery Life
The Axonics device is designed for 15+ years of battery life. Pacemakers typically last 5 to 15 years depending on usage.
4. MRI Compatibility
The Axonics device is full-body MRI compatible at 1.5T and 3T without restrictions — a major advantage for patients who may need future MRI scans. Older pacemakers may not be MRI-compatible.
Can I Get an Axonics Device If I Already Have a Pacemaker?
This requires careful coordination between your cardiologist and SNM specialist. Dr. McJunkin at Bladder Centers of America works with cardiac patients regularly and will coordinate with your cardiac team to ensure any decision is made safely. Learn if you are a candidate for SNM.
Is Axonics SNM Right for You?
You may be a candidate if you experience 8+ bathroom trips per day, strong sudden urges, leakage, or nighttime waking. Medicare and most major insurance plans cover SNM for qualifying patients.
