Description

The Sparrow Ascent is a transcutaneous auricular neurostimulation (tAN) system intended to provide non-invasive, transcutaneous stimulation of the nerves on and/or around the auricle (ear). The device is indicated as an aid in the reduction of opioid withdrawal symptoms in adult patients. The Sparrow Ascent is a battery operated, prescription device that delivers mild electrical stimulation to the nerves on and/or around the auricle (ear), which carry information to the central nervous system. The Sparrow Ascent is to be used in clinical environments (e.g., doctor’s office, clinics, rehab centers, and hospitals) and/or at home. Users of the subject device include adults experiencing opioid withdrawal symptoms. Stimulation parameters (i.e., the strength of stimulation) are set by the user’s clinician, and users can only adjust stimulation intensity at home. The system consists of three main components 1) a disposable Earpiece, 2) a Cable, and 3) the External Pulse Generator (EPG).
