How VNS Therapy Works

VNS Therapy is a personalized, comprehensive approach to seizure control.


The VNS Therapy Difference

Designed for more seizure-free moments, VNS Therapy controls seizures in 3 ways: Prevention, Response and On-Demand.


What does VNS Therapy involve?

VNS Therapy is delivered through a device that sends mild pulses to the vagus nerve at regular intervals throughout the day in an effort to prevent seizures.

An additional dose of therapy may stop or shorten your seizure, decrease its intensity and improve your recovery.

VNS Therapy includes a short outpatient procedure which takes about an hour.

VNS Therapy is not brain surgery.

The 3 modes of VNS Therapy explained

Standard Mode
Prevention Delivery

Therapy is delivered at regular intervals all day, every day in an effort to prevent seizures.

Detect & Respond*
Responsive Delivery

Automatic delivery of an extra dose of therapy activated when a rapid increase in heart rate is detected, which may be associated with seizures. This may stop or shorten a seizure once it starts.

Magnet Mode
On-Demand Delivery

Provides you or a caregiver the ability to manually deliver an additional dose of therapy in an effort to stop or shorten a seizure once it starts.

*Also known as AutoStim Mode. Only available in models 106 and 1000.

An extra dose of therapy may stop or shorten a seizure

An extra dose of therapy may be administered using the VNS Therapy magnet or via Detect & Respond Mode (models 106 and 1000 only).

VNS Therapy's latest technology includes features that offer treatment personalization and easier management

Day/Night Programming

Optional feature that allows your doctor to customize VNS Theapy based on your lifestyle preferences or side effect management. Your doctor can program your device to different settings for any two periods of time during a 24-hour period.

Scheduled Programming

Scheduled Programming allows your doctor to pre-program your device to automatically change therapy settings at intervals he or she chooses to quickly reach your targeted dose. This option can reduce the need for you to attend follow up appointments for programming, giving you time back to live your best life.
