The Earpiece is a disposable component of the Sparrow Ascent and is designed to stay adhered to the skin of the left or right ear for up to 24 hours of electrical connectivity. The Inner Electrode interfaces with the cymba concha and the Outer Electrode interfaces with the trigeminal nerve. The Back Electrode is the return Electrode for both the Inner and Outer Electrodes.
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.
