Living With an InterStim System

Overactive Bladder

You may be able to do things you were not able to do before receiveing Medtronic Bladder Control Therapy (Sacral Neuromodulation delivered by the InterStim® System)  — take long walks through the park, see movies at the theater, or travel. While it may take a while to adjust to the therapy, you should be able to resume normal activities soon.

Remember: Even after you’ve made a full recovery from surgery and resumed your normal routine, it’s important to stay in touch with your doctor about any questions or concerns you have.

Common Concerns

Some people report feeling worried because they don’t feel stimulation all the time. If this is a concern of yours, keep in mind that your doctor may have programmed your neurostimulator to turn on and off at regular intervals. In addition, quick movements or a change in posture may move the implanted lead closer to your sacral nerve. This can feel like an unexpected change in stimulation sensation even though the stimulation level has not changed. If you are not receiving adequate symptom relief, contact your doctor.

If you have questions about your neuromodulation therapy, if you are not receiving adequate symptom relief, or if your OAB symptoms return, call your doctor.

Getting an MRI Head Scan

When following specific guidelines from Medtronic, MRI technologists can safely perform an MRI head scan on people with an implanted InterStim II system and specific InterStim I systems. Full-body MRI scans may result in severe injury to you or damage to your device.

If a doctor prescribes an MRI head scan for you, inform the doctor and MRI technicians that you have an implanted device prior to your MRI examination appointment. Full MRI safety information is available for your doctor or MRI technician at or by calling 1-800-510-6735.

Patient Therapy Guide

Your doctor should give you an InterStim Therapy patient guide when you consider the evaluation. A PDF of the manual is also available on the area of that requires you to log in. To register, you'll need your evaluation procedure date or your implant procedure date.
