Cobra EMG ET Tube - EMG electrode for Universal Recurrent Laryngeal Nerve Monitoring - Size 7 mm - Intraoperative Neuromonitoring Products

Cobra 3-Plate

Universal EMG Endotracheal Tube

Patented EMG electrode, maximize RLN monitoring precision for safer surgical outcomes.

Product Overview

Neurovision Medical Products offers the Cobra 3-Plate EMG endotracheal tube, enabling recurrent laryngeal nerve monitoring while maintaining a patent airway.

The C3P design improves a surgeon’s ability to identify and monitor the RLN during thyroid surgery and other ENT procedures. The EMG tube features the longest electrodes available, allowing it to reach the optimal depth for improved contact with the vocal folds and reliable EMG signals.

The Cobra 3P EMG tube is compatible with any nerve monitoring system. The new EMG tube features a 3-plate electrode configuration utilizing patented conductive silver ink EMG electrodes for precision and optimal performance. Neurovision’s atraumatic design integrates patented EMG electrodes onto a standard PVC ET tube, reducing airway trauma and improving RLN monitoring and surgical outcomes.1

Product Features

Atraumatic EMG Electrode

Cobra 3-Plate is the newest EMG electrode by Neurovision Medical Products. The redesigned EMG ET tube enhanced their patented EMG electrodes for precise RLN monitoring during surgery.

The atraumatic design now features three elongated conductive silver ink electrodes for improved contact with the vocal cords and a reduced sensitivity to movement for the most reliable nerve activity detection. With a zero profile*, the atraumatic electrodes are gentle on the patient’s airway and do not increase ETT size.

The integration of standard PVC endotracheal tubes with EMG electrodes has been proven to be safe and effective for prolonged, continuous monitoring during surgical procedures.2

Universal RLN Monitoring

Cobra 3P universal design is compatible with single-channel and multi-channel nerve monitoring systems.

Increased EMG electrode size improves contact with the vocal cords, even in longer airways or larger patients.

High-quality EMG electrode for reliable RLN monitoring features 1.5 mm touch-proof connectors with color-coded wires that identify the lateral and posterior plates.

Secure EMG Tube Design

Additional features of the Cobra 3P EMG ET tube enhance the intraoperative neuromonitoring performance.

A high volume, low-pressure cuff, improves the air seal on the trachea.

The EMG electrode and wire integration are hermetically sealed to prevent fluids from disrupting the EMG signal and reduce unwanted functional issues. All lead wires use a standard DIN (42802) plug for an easy and secure connection to any nerve monitoring system.

The innovative NEW design with patented technology creates a truly universal intraoperative neuromonitoring EMG ET tube with an enhanced IONM performance overall.
