Dec. 4, 2014 -- The FDA has approved an injectable microchip nerve-stimulation device for the relief of ongoing back and leg pain.
The Stimwave Freedom Spinal Cord Stimulation (SCS) system is expected to be available in the United States next January, the company, Stimwave Technologies Inc., said in a statement.
The device is already being sold in Europe to treat back and leg pain
Severe chronic pain can in some cases be treated using neurostimulators that disrupt nerve signals moving up to the brain. Most such devices can benefit from being much smaller and not having to rely on an internal battery can also be a major advantage. That is why FDA’s clearance of Stimwave Technologies‘ wireless Freedom spinal cord stimulation system is so exciting.
The implant itself is tiny compared to the pacemaker-sized neurostimulators we’re used to, and it doesn’t even have wires leading from the implant to the stimulation site. It’s actually 95% smaller than the smallest implantable battery on the market. Instead, it’s an all-in-one device that can be accurately injected near the spinal nerves via a conventional needle. Additionally, the Freedom implant doesn’t rule out future MRI scans and can be safely worn even when inside a 3T magnetic field (as long as certain precautions are taken).
