Indications for Use
The BIONEN Disposable Concentric Needle electrodes are sterile electrodes indicated for recording muscle activity for Electro-myography (EMG) applications. The electrodes are for single patient use only. The BIONEN Disposable Monopolar/Subdermal Needle electrodes are sterile electrodes indicated for recording muscle activity for Electro - myography (EMG) and/or Electroencephalography (EEG) applications. The electrodes are for single patient use only. The BIONEN Disposable Monopolar Needle electrodes are sterile electrodes indicated for injection of Botulinum Toxin while recording muscle activity with Electroymyography (EMG) applications. The electrodes are for single patient use only.
Device Story
BIONEN needle electrodes (concentric, monopolar, subdermal) are sterile, single-use devices for recording biopotential signals (EMG/EEG) or facilitating Botulinum Toxin injection. Concentric needles feature a stainless steel cannula (reference) and an inner stainless steel or platinum conductor (active measure point) separated by insulation. Monopolar/subdermal needles consist of a formed stainless steel needle with an attached lead wire. Monopolar needles for injection feature an open lumen. All devices terminate in touch-proof safety connectors to prevent contact with hazardous voltage. Used in clinical settings by healthcare professionals, the electrodes connect to EMG/EEG recording equipment. The output is a biopotential signal used by clinicians for neuromuscular system examination or monitoring during drug delivery. Benefits include diagnostic utility for neuromuscular conditions and precise guidance for toxin injection.
Clinical Evidence
No clinical data. Evidence consists of bench testing and biocompatibility studies. Bench testing verified penetration force, friction force, electrical continuity, and isolation. Biocompatibility testing (ISO 10993-5, -10) confirmed non-cytotoxicity, non-irritation, and non-sensitization. Shelf-life and sterility (gamma irradiation) were validated.
Technological Characteristics
Stainless steel cannula; inner conductor (stainless steel or platinum); epoxy insulator; plastic (NYLON/PE) hub; PTFE coating (monopolar injection needles). Sensing: biopotential recording. Connectivity: touch-proof safety connector (DIN 42802 compatible). Sterilization: Gamma irradiation. Standards: IEC 60601-1, ISO 10993-1/5/10, ISO 11137, DIN 13097.
Indications for Use
Indicated for recording muscle activity for EMG and/or EEG applications, or for injection of Botulinum Toxin while recording muscle activity via EMG. For single patient use only.
Regulatory Classification
Identification
A diagnostic electromyograph needle electrode is a monopolar or bipolar needle intended to be inserted into muscle or nerve tissue to sense bioelectrical signals. The device is intended for medical purposes for use in connection with electromyography (recording the intrinsic electrical properties of skeletal muscle).

#### Device Description:
The BIONEN Disposable Concentric Needle Electrode is used for electromyography (EMG) recording for examination of the peripheral neuromuscular system, by registration of the electrical activity from the muscles.
BIONEN Disposable Concentric Needle Electrode consists of a stainless steel cannula and an inner conductor of stainless steel or platinum. Between these two conductors there is an insulation layer. The inner conductor is the active measure point and the outer conductor of stainless steel is the reference point. The Stainless steel cannula is coated with a low friction lubricant.
The BIONEN Disposable Monopolar/Subdermal Needle Electrode is intended to be inserted in the subdermal, muscle or nerve tissue for use with recording equipment for the recording of biopotentials signals, EEG or EMG, and proximally connected to electromyography/Electroencephalogram recording equipment. The electrodes consist of a formed stainless steel needle with a lead wire attached. The wire can be directly connected or removable and terminates in a safety connector that cannot be connected to an AC power outlet or and cannot get in touch with possible hazardous voltage.
