Implantable neurostimulation devices are another surgical option. If medications or treatments haven’t provided satisfactory relief and other surgeries aren't ideal for you, these devices can help prevent or interrupt seizures. Once implanted, these devices aren't noticeable or bothersome and can remain in place for your lifetime.
Vagus Nerve Stimulator (VNS)
A pacemaker-like device or battery is implanted under your collar bone. 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 to the brain 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. The procedure to place a VNS can be performed on an outpatient basis, meaning you'd be able to go home that same day. 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 activity and identifies abnormal patterns that could lead to a seizure. Then it sends small electrical shocks to prevent or interrupt seizures.
Deep Brain Stimulator (DBS)
A pacemaker-like device is implanted under your collar bone that transmits electrical signals through two small wires to targeted areas of the brain. These signals are delivered on a schedule and help stop seizures from beginning or spreading.
