NIM VITAL™ Nerve Monitoring System

NIM Vital™ nerve monitoring system provides detailed intraoperative nerve condition information to inspire surgical strategy1,2 and help improve patient outcomes.3




NIM Vital™ provides detailed intraoperative nerve condition information to inspire surgical strategy2 and help improve patient outcomes3*:

  • Proprietary technology notifies you in real time of nerve condition — visually and audibly.
  • NIM Nervassure™ continuous monitoring technology provides real-time feedback on nerve function so you can adjust course, if necessary, during thyroid surgery and other procedures affecting head and neck nerves.1
  • NIM NerveTrend™ EMG reporting enables nerve condition tracking throughout a procedure, even when using intermittent nerve monitoring.
  • During both continuous and intermittent trending, green, yellow, and red status bars provide visual information and their associated tones provide audible cues, making monitoring nerve function and interpreting EMG trends easier than ever.4
  • NIM Vital™ nerve condition information can be captured in a single, meaningful snapshot.

Experience a Quieter procedure

  • Intelligent noise suppression reduces interference from electrical equipment.16,†
  • Clinically relevant audible cues signal nerve functional status.5
  • Proprietary technology enables monitoring nerve condition through Medtronic Advanced Energy Device use.6

A wireless design Reduces constraints

  • Wireless patient interface and muting streamline the number of wires, reducing risk of tripping in the OR and simplifying setup/tear down.7
  • Wireless console projection onto LCD screens means you can place NIM Vital™ anywhere in the OR.

Creating an
Efficient workflow

  • Touchscreen and streamlined user interface provide a more intuitive workflow.4,8
  • Smart troubleshooting pop-ups alert staff to system issues and offer resolution protocols.
  • Enhanced remote control of critical settings from the surgical field.

Future features Unlocked with ease

The NIM Vital™ product platform allows easy expansion to unlock additional future functionality, enabling use of nerve monitoring to help protect nerve condition and patients’ quality of life.9-11

Fully mobile And ergonomic

NIM™ cart enhancements include high quality industrial wheels which improve cart maneuverability. An ergonomic handle is designed to transport the system with ease.

More confidence
Better results

  • Increases operative efficiency and precision12
  • Reduces risk of intraoperative nerve damage9,10
  • Reduces time needed to identify motor nerves12
  • Helps surgeon identify site of nerve injury13


Our NIM™ intraoperative neuromonitoring systems is an electromyographic (EMG) monitor for use during various surgeries, including ENT and general surgical procedures in which a nerve may be at risk due to unintentional manipulation. NIM™ nerve monitoring electrodes are placed in the appropriate muscle locations in the patient for the procedure being performed. (Color-coded placement guides are included in the NIM™ software.)

These electrodes are connected to the NIM™ system, which monitors EMG activity from muscles innervated by the affected nerve. When a particular nerve has been activated or stimulated, the NIM™ system warns the surgeon and operating room staff, providing both visual alerts on the color touchscreen monitor and audio feedback to help minimize trauma to the nerve.9,10

Surgeons can use monopolar and bipolar stimulating probes and dissection instruments with the NIM™ system to assist in early nerve identification and confirmation. These tools may be used to locate, identify, and map the particular nerve and branches, as well as verify nerve function and integrity.

By combining sophisticated hardware electronics and intuitive software4, our NIM™ intraoperative neuromonitoring systems help surgeons perform critical procedures while helping to preserve nerve function and helping to maintain patient quality of life.9-11
