New Demipulse generators for certain hard-to-treat seizures are significantly smaller and lighter than earlier units and feature advanced technology to improve monitoring and programming of the devices.
Vagal nerve stimulation (VNS) therapy, approved in 1997, does not involve brain therapy. The pulse generator is implanted under the skin in the upper chest and delivers intermittent signals to the brain via one or two wires attached to the left vagus nerve in the neck. Studies show that VNS therapy may also benefit some people with chronic depression.
