Frequently Asked Questions

Frequently Asked Questions

  • How do I find out if I am eligible for Vivistim Paired VNS Therapy?

    To determine if you are eligible for Vivistim Paired VNS Therapy, you will undergo an initial assessment with a rehabilitation professional to evaluate your current hand and arm function. You will then be referred for a consultation with a surgeon to determine if you are a good candidate for the implantation procedure.

  • Can I feel the implant?

    Most people will not feel the implant under their skin. Immediately after the procedure, you may have some soreness in your upper chest where the device was implanted, but it should resolve in time.

  • Can I feel the stimulation?

    Typically, people do not feel the pulses during stimulation. Settings can be adjusted by your clinician or therapist during your in-office visit to make Paired VNS comfortable for you.

  • What sort of improvement can I expect?

    Response to treatment varies for each person. In a clinical trial, Paired VNS Therapy study subjects experienced 2-3 times more improvement in hand and arm function than those who received intense rehabilitation therapy without Paired VNS.

  • How quickly will it work?

    In a clinical trial, Paired VNS Therapy study subjects reported improvement as early as 2-3 weeks. Individual results may vary.

  • How long does the battery last?

    The battery is expected to last approximately 5 years at typical settings. Your specific situation and settings may result in shorter or longer battery life. During scheduled visits with your clinician, they will use the system software to check the battery status of your implant.

  • What happens if I stop using it?

    As you perform your prescribed at-home therapy, you may continue to see improvement in your hand and arm function. Stopping Paired VNS Therapy does not inherently have adverse effects but may slow down or stop your progress. Talk to your clinician to learn more.

  • Can the system be removed when I have achieved my goals, or if I change my mind?

    The Vivistim System may be removed at any time, in a same-day outpatient procedure. Depending on your surgeon’s decision, all or part of the implants can be removed at any time. Talk with your surgeon for further details.

  • Are there side effects?

    Some common side effects of VNS Therapy include hoarseness, shortness of breath, throat irritation, pain, and coughing. While not observed with Vivistim, infection is a risk associated with implantable surgeries. Please see for more safety information.

  • Does Paired VNS Therapy use medication?

    No. Paired VNS Therapy is an implanted device and system used in conjunction with rehabilitation therapy.

  • Can I speak to someone who has used the Vivistim Paired VNS System?

    Yes! Reach out to MicroTransponder Customer Service at 855-628-9375 or to put you in touch with a Vivistim user or a rehabilitation professional specialized in Paired VNS Therapy.

  • Can I travel?

    Yes. There are no specific travel restrictions. Flying will not affect the system or the delivery of stimulation. You may want to inform the airport or security personnel that you have an implant by showing your Patient Identification Implant Card. Properly operating metal detectors are not expected to affect the Vivistim System. 

  • Are there any restrictions after the surgical procedure?

    Once you have the Vivistim System, you should not undergo the following: 

    • Diathermy 
    • Vagotomy 

    Also, talk to your physician if you wish to participate in contact sports. 

  • Are there MRI restrictions?

    Certain types of MRI can be performed, provided specific guidelines are followed. Before scheduling an MRI, contact your Vivistim surgeon or physician. 

  • What should I do if I lose my Vivistim Magnet?

    For a replacement magnet, please contact MicroTransponder Customer Service at 855-628-9375 or 

  • Will my Vivistim Implant turn on if I walk past a magnet, like one on a refrigerator?

    Household magnets are not strong enough to affect an implanted Vivistim device.

  • What is the purpose of the Patient Identification Implant Card?

    The wallet-sized card lets others know you are using the Vivistim System. It will also make them aware of MRI conditions, your clinician’s name and phone number, and which product you have.
