Device type (GMDN): Opioid withdrawal/irritable bowel symptom-relief periauricular nerve percutaneous electrical stimulator

A body-worn, electronic device intended to provide percutaneous electrical nerve field stimulation (PENFS) applied close to cranial/peripheral nerves around the external ear to achieve remote symptom relief mediated by central nervous system (CNS) pathways and structures [e.g., amygdala, spinal cord neurons]; depending on the treatment protocol and device settings it may be used for opioid withdrawal symptoms (e.g., bone/joint aches, tremor, anxiety), or irritable bowel syndrome [IBS]-associated functional abdominal pain (FAP). It consists of an electrical pulse generator with minimally-invasive electrodes, and accessories (e.g., adhesives, transilluminator). This is a single-use device.
