|St. Jude Medical Receives European CE Mark Approval of Eon Mini Neurostimulator, the World’s Smallest Rechargeable Device to Treat Chronic Migraine|
Additional approvals received for Eon and EonC neurostimulators, expanding the device options for physicians to manage the pain and disability associated with intractable chronic migraine
“Intractable chronic migraine is one of the most difficult-to-treat
headache disorders,” said Professor
The Eon and Genesis systems deliver peripheral nerve stimulation (PNS) of the occipital nerves to manage the pain and disability associated with intractable chronic migraine. This type of migraine is defined as headache lasting at least four hours per day for 15 or more days per month, causing at least moderate disability, and not responding to three or more preventive drugs. PNS therapy for this condition involves the delivery of mild electrical pulses to the occipital nerves that are located just beneath the skin in the back of the head. A small electrical lead or leads are placed under the skin and connected to the neurostimulator, which produces the pulses of stimulation.
Prior to receiving these approvals,
“Neurostimulation technology represents an exciting new approach to
treat intractable chronic migraine,” said
Eon Mini Neurostimulator
Approximately the size of a man’s watch, the rechargeable Eon Mini neurostimulator has a thin 10-mm profile and weighs 29 grams (approximately 1.0 oz). Its small size allows for a smaller incision, which gives physicians increased flexibility in selecting the implant location and is intended to make the site less visible and more comfortable for patients.
Featuring a rechargeable battery, the Eon neurostimulator is designed to provide stimulation over a long period of time, making it a good choice for patients who require high-power stimulation settings and need to use the system for a large percentage of the day. The Eon device can provide sustainable therapy and maintain a reasonable recharge interval for 10 years, potentially resulting in fewer battery replacement surgeries.
The EonC neurostimulator provides a convenient option for patients who prefer or require the simplicity of a non-rechargeable medical device. The device features the greatest battery capacity of any primary cell neurostimulator.
St. Jude Medical’s neurostimulators are the only fully implantable
neurostimulation devices approved in
Migraine is a neurological disorder characterized by a number of specific symptoms that can last for hours or days at a time. The severity of each migraine attack can vary widely, with typical symptoms ranging from sensitivity to light, noise and motion to nausea and vomiting in addition to headache. In general, chronic migraine sufferers have progressed to the level where they have migraine or migraine-like symptoms on more days than they are migraine free.
