Nerve Monitoring Systems

Related Nerve Monitoring Products

Our nerve monitoring products and accessories can be used in conjunction with NIM® Nerve Monitoring Systems during a variety of surgical procedures. These include ENT surgeries, such as otologic procedures and thyroidectomies, as well as other operations performed by endocrine, general, and peripheral surgeons.

Why Use a NIM EMG Tube?

Even experienced surgeons find it difficult to visually identify the recurrent laryngeal nerve (RLN) or vagus nerve during thyroid surgery and other neck dissections. Studies show that the rate of RLN injury is under-estimated1-6 and intraoperative nerve monitoring of the RLN is recommended as a risk-minimizing tool.1-4,7-15

NIM® EMG Tubes provide an open airway for patient ventilation and intraoperative nerve monitoring of both vocal cords. If nerve function changes, the NIM System alerts you with visual and audible warnings to help reduce the risk of patient injury.

NIM TriVantage EMG Tube

The NIM TriVantage® EMG Tube is a standard size, non-reinforced, DEHP-free PVC tube that features smooth, conductive silver ink electrodes and a cross-band to guide placement. It has reduced sensitivity to rotation and movement while offering increased EMG responses that facilitate improved nerve dissection.

Together with the NIM System, a properly positioned NIM EMG Tube can reduce the risk of injury to your patient by helping you to:

  • Identify the recurrent laryngeal or vagus nerves
  • Control manipulation during dissection
  • Verify the integrity of the nerve prior to surgical closure

Only NIM EMG Tubes are tested and validated for use with NIM nerve monitors.

  • Partial laryngectomy
  • Substernal goiter
  • Thyroidectomy
