VNS Therapy™ post-implant education

VNS Therapy™ for Drug-Resistant Epilepsy

VNS Therapy™ is an add-on neuromodulation treatment designed for people with drug-resistant epilepsy 4 years of age and older with partial onset seizures. It can safely lead to fewer and shorter seizures and better recovery after seizures.

VNS Therapy™ is a small device implanted under the skin in the chest and connected to the left vagus nerve in the neck. VNS Therapy™ delivers mild pulses to the brain through the vagus nerve to help prevent seizures before they start and help stop them if they do.

VNS Therapy® Magnet

The VNS Therapy® Magnet allows patients and caregivers to manually deliver an extra dose of therapy which can stop a seizure once it starts. It can also be used to help shorten the duration of a seizure and improve recovery time after seizures.

Two magnets are provided with the VNS Therapy® System. The magnet is surrounded by a plastic casing similar to the shape of a watch and can be worn on the wrist or kept nearby in a pocket or bag.

If you feel a seizure is about to begin, or once a seizure is happening, the magnet can be used to initiate an extra dose of stimulation. The magnet can be used more than once during a seizure if necessary. Using the magnet more than once will not harm you or the device.
