4N.-vagusstimulatie Therapie Milde elektrische pulsen afgegeven aan de linker n. vagus in de nek die signalen afgeven aan de hersenenAutomatische intermitterende stimulatieMagneet gebruik voor patiëntdirecte controle over bijwerkingenEenvoudig te programmerenVagus nerve stimulation (VNS) is delivered through a pacemaker-like pulse generator surgically implanted into a subcutaneous pocket in the left chest area below the left clavicle or in the left axilla.Since FDA approval in July 1997, the VNS Therapy pulse generator system has been implanted in more than 17,000 patients world-wide.Stimulation parameters are set through a telemetric wand that is held over the area of the implanted pulse generator and controlled through special software administered by the treating physician.Electrical pulses reach the brain via the left vagus nerve, where the lead is attached. Through programming, stimulation can be adjusted for each patient. Furthermore, patients can acutely control stimulation and side effects via a hand-held magnet.
5Pulsgenerator en elektrode Model 1019 mm dikWeegt 30 gGaat 6-11-jaar meeThe VNS Therapy pulse generator is similar physically to a heart pacemaker and is the approximate size of a thin stopwatch. However, unlike a pacemaker, the patient does not have to be concerned with normal appliances, security systems, etc.The Model 102 pulse generator is connected to a single-pin, bipolar lead, which is attached to the left vagus nerve in the cervical area. The VNS Therapy implant weighs just 25 g and is approximately 7 mm thick.The Model 100 generator was approximately twice as large and heavy as the new Model 102 and had a shorter battery life. The current Model 102 has a typical battery life of 6 to 11 years, based on commonly used parameters.Upon routine battery replacement, only the pulse generator is replaced, not the lead.
