The StimRouter neuromodulation system is a minimally invasive implantable device for treating chronic peripheral nerve pain. A clinical study of 94 patients found that StimRouter treatment significantly reduced pain and improved quality of life compared to a control group, with no serious device-related adverse events. The StimRouter system consists of an implanted lead, external pulse transmitter worn on the skin, and patient programmer to control stimulation programs. It targets pain at its precise origin with a one-time outpatient procedure.
