St. Jude Medical has received European approval to market the world’s smallest implantable deep brain stimulator to help control the symptoms of Parkinson’s disease. The Brio device weighs 29 grams (~1 ounce) and has a 10 millimeter profile. The battery is rated to last for up to 10 years with recharges, so the first patient, a 67 year old German man, recently implanted with the device won’t need a replacement for up to a decade, maybe until 2019.
From the announcement:
The Brio DBS system delivers mild electrical pulses to specific targets in the brain, stimulating the structures that are involved in motor control. The system consists of a neurostimulator – a surgically implanted battery-operated device that generates the electrical pulses – and leads which carry the pulses to the brain to influence the irregular nerve signals responsible for the symptoms of Parkinson’s disease.
In addition to its small size, the Brio neurostimulator has the longest battery life of any rechargeable DBS device currently on the market with a 10-year battery longevity approval. For patients this means the device should provide sustainable therapy and maintain a reasonable recharge interval for at least 10 years of use at high settings. The device’s battery longevity may also maximize the time between device replacement procedures.
The Brio neurostimulator also features:Constant current circuitry that automatically adjusts to deliver consistent therapy over time. A dual header that accommodates two leads, allowing for bilateral stimulation from one device. High power capability, making it an appropriate choice for patients who require high energy settings to control their symptoms. A rechargeable battery that can be easily charged through a portable, wireless charging system, allowing patients the freedom to recharge comfortably while doing other activities. Additionally, St. Jude Medical has recently received CE Mark approval for the Guardian™ Burr Hole Cover System, a DBS system component that allows physicians to efficiently secure the electrical leads. The Guardian System is compatible with all St. Jude Medical DBS leads.
