Disposable Concentric Needle Electrode 0.30x25mm Red (TE/B50700-001) +5 more mo…

These electrodes are primarily used in physical medicine, particularly for electromyography (EMG) and nerve conduction studies. Their design—with a central stimulating wire surrounded by a conductive outer shaft—allows for precise percutaneous insertion to capture biopotential signals accurately. This makes them ideal for diagnosing neuromuscular conditions, muscle dysfunctions, and nerve-related disorders in specialized physical medicine settings.

These electrodes are intended for single-use only and are supplied sterile. This design ensures patient safety by eliminating cross-contamination risks between uses. Clinicians should follow standard single-use protocols, discarding them immediately after one procedure and opening a new sterile package for subsequent patients, which aligns with best practices for sterile medical devices.

Six sizes are available: 0.30x25mm (Red), 0.40x25mm (Yellow), 0.30x30mm (Pink), 0.45x37mm (Green), 0.45x50mm (Blue), and 0.60x75mm (Violet). The first number indicates the outer diameter (in mm), while the second indicates the length. Selection depends on the patient’s anatomy, the depth of the target muscle or nerve, and the clinician’s preference for precision. For example, shorter lengths (e.g., 25mm) are typically used for superficial muscles, while longer lengths (e.g., 75mm) may be needed for deeper structures.

These electrodes must be stored according to the manufacturer’s guidelines to preserve sterility and packaging integrity. They come pre-sterilized in sealed packaging, so storage should avoid exposure to moisture, extreme temperatures, or physical damage. Always check the packaging for signs of compromise before use, and adhere to expiration dates to ensure optimal performance and compliance with sterile medical device protocols.

These electrodes have undergone FDA 510(k) clearance (K253581) and comply with MDD (Medical Device Directive) authorizations, confirming they meet U.S. and EU regulatory standards for diagnostic electromyograph devices. This means they are classified as Class II devices under FDA regulations and are suitable for use in clinical settings where electromyography is performed. Purchasers should verify local regulatory compliance and ensure proper documentation is maintained.
