Patients with chronic, intractable low back or leg pain have a new option for pain relief from an electrical stimulation device that doesn’t cause paresthesia. The Senza System, which delivers high-frequency stimulation, received FDA approval in early May.
“The FDA has approved several other totally implanted spinal cord stimulators for pain reduction, but this system is unique because it delivers a high-frequency output of 10 kHz that does not cause a tingling sensation—called paresthesia—in patients,” William Maisel, MD, MPH, acting director of the Office of Device Evaluation at FDA’s Center for Devices and Radiological Health, said in a statement (http://1.usa.gov/1JwKgtt).
