Acute Human Study: StimRouter for Peripheral Nerve Stimulation of Discrete Peripheral Nerves

This study is being done to see how well a new investigational medical device, the StimRouter (STR) System, will work to treat the chronic pain in people who have failed previous treatments for Carpal Tunnel Syndrome (CTS) pain, including surgery. These people have been treated for CTS pain before including surgical carpal tunnel release, but without good results, and they are still having pain. The study will look at both the good and bad effects of the StimRouter System for treating this kind of pain and as a general peripheral nerve stimulation device for treating chronic pain. The study will also help to understand other possible uses for the StimRouter System.
