Frequently asked questions

Why is this therapy different? 

You can try it before you decide, and it’s reversible if you change your mind later. 

What can this therapy do for me? 

It can significantly improve quality of life by reducing your symptoms. It’s proven to work in people who have chronic FI.1

Will it cure my condition? 

No. It can help some people achieve complete continence, but it’s not a cure. If the neurostimulator is turned off or removed, symptoms can return.

What does the stimulation feel like? 

Most people describe it as a tingling, flutter, or vibration in the pelvic area. It should not be painful. Stimulation settings can be adjusted, and sensations will vary from person to person. 

Does the therapy work long term? 

Clinical data shows that after five years, people using the InterStim™ system continue to experience significant improvements in quality of life.1 No other SNM system has this long-term data. Your experience may be different. More people rely on Medtronic than any other SNM system to provide this relief. 

Can I have an MRI? 

People with an InterStim™ system can have a full-body MRI scan under certain conditions. Your doctor will determine whether you meet those conditions. 

Will insurance cover the costs? 

Medicare and many private insurance companies cover this therapy. Talk to your doctor to learn more about your insurance coverage.
