This device is an accessory to the electromyography recording machine, used for assessment of skeletal muscles. EMG electrodes are the property of a licensed physician and intended for single patient use, only. ## Device Story Detachable Monopolar EMG Needle Electrode functions as an accessory to electromyography (EMG) recording systems. Device consists of a needle electrode inserted into muscle or nerve tissue to detect bioelectrical signals. Signals are transmitted to the EMG machine for analysis by a physician. Used in clinical settings for skeletal muscle assessment. Intended for single-patient use to prevent cross-contamination. Provides diagnostic data to assist physicians in evaluating neuromuscular function. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Monopolar needle electrode; designed for insertion into muscle/nerve tissue; accessory to EMG recording equipment; single-patient use; non-sterile/sterile (implied by single-use requirement). ## Regulatory Identification A needle electrode is a device which is placed subcutaneously to stimulate or to record electrical signals. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
