StimRouter is approved by the FDA to treat chronic pain of peripheral nerve origin, excluding pain in the craniofacial region. StimRouter is a minimally invasive neuromodulation medical device consisting of a thin, implanted lead with conductive electrode, external pulse transmitter (EPT), and hand-held wireless patient programmer. Electrical signals are transmitted transdermally from the EPT through the electrode, down the lead to the target nerve. StimRouter is programmed at the direction of the physician to meet patient requirements but is controlled by the patient to address the patients' specific, changing pain management needs.
