It delivers electrical stimuli to the nervous system to assess corticospinal axonal conduction. By monitoring responses, the device helps identify potential dysfunction caused by mechanical trauma (traction, shearing, laceration, compression) or vascular insufficiency during surgery. The output allows healthcare providers to assess nerve integrity in real-time, facilitating intraoperative decision-making to prevent permanent neurological damage. ## Clinical Evidence No clinical data provided; device clearance based on substantial equivalence to existing evoked response electrical stimulators. ## Technological Characteristics Evoked response electrical stimulator; 21 CFR 882.1870; Product Code GWF; Class II device. Operates via electrical stimulation of neural pathways. ## Regulatory Identification An evoked response electrical stimulator is a device used to apply an electrical stimulus to a patient by means of skin electrodes for the purpose of measuring the evoked response. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
