If you are not a candidate for epilepsy surgery and medications or other treatments haven’t provided satisfactory relief, implantable devices can help prevent or interrupt seizures. Apart from the surgery to place them, these devices are painless and can remain in place for your lifetime.
Vagus Nerve Stimulator (VNS)
A pacemaker-like device is implanted in your chest wall. A wire connects it to the left vagus nerve in your neck, which is connected to your brainstem. On a schedule, the device delivers weak electrical pulses that help prevent seizures. A handheld magnet allows you to activate the stimulator (for example, if you sense a seizure is imminent) or deactivate it. Our epileptologists also offer investigational VNS trials to test new ways of programming the device to detect seizures before they happen.
Responsive Neurostimulator (RNS)
An RNS works like a pacemaker for the brain. It is implanted into your skull and connects to electrodes placed directly on or in the brain. It monitors your brain waves and gives small electrical shocks to interrupt the electrical patterns that may lead to seizures.
Deep Brain Stimulator (DBS)
A pacemaker-like device is implanted in your chest wall, and two electrodes are implanted in targeted areas of the brain -- one on each side of your head. Through these electrodes, small electrical impulses help stop seizures from beginning or spreading throughout your brain.
