Main application areas are:

C2 NerveMonitor – Easy-to-use neuromonitoring for thyroid surgery, ENT, spine and a range of other applications

Innovation delivering quality and reliability for preservation of nerve function

The C2 NerveMonitor is the result of inomed’s 20+ years of experience in the field of nerve monitoring (IONM). The C2 is available as a 4 or 8 channel EMG monitor. The system includes high performance differential amplifiers and two independent stimulators: one stimulator may be used for direct nerve stimulation with handheld probes and the second for applications such as continuous vagus nerve monitoring , delivering stimulation at a user-defined rate and amplitude.

Proven methods of neuromonitoring – Simplified

Designed for everyday use in the operating room, the C2 NerveMonitor benefits from an intuitive user interface that makes the system very easy to use indeed. The C2 combines simplicity of operation with a clear visual display showing waveform, trends and numbers, as well as auditory feedback. All monitoring sessions are recorded and can be printed in the form of a comprehensive user-defined report. All the device’s components have been designed to meet European and international safety and quality standards. Procedures that can be monitored using the C2 NerveMonitor include thyroid surgery and a range of user-specific programs for ENT and spinal surgery . The sophisticated easy-to-use interface and a comprehensive range of accessories make the C2 NerveMonitor a versatile and portable system for the OR.

Neuromonitoring as the standard of care

Neuromonitoring is becoming the standard of care for a wide range of revisionary surgical procedures. This is particularly true of procedures for the thyroid gland. Common to all surgical interventions, the requirement for documentation from monitoring thyroid surgery is either mandatory or becoming an essential part of patient care. A major strength of the C2 NerveMonitor is the ability to document and produce fast and accurate reports. The C2 NerveMonitor provides a barcode scanner to enable fast input of patient identification, while the systems also includes tools for easy data integration into patient management databases and intuitive ways to easily create patient monitoring reports. The C2 exemplifies the application of innovation in delivering quality patient care.


  • Ease of use for Operating Room staff
  • Synthetic sound technology for easy audio interpretation of nerve response
  • Clear presentation of the muscle response in the form of EMG waveforms
  • Channel Select software for optimal signal quality in thyroid surgery
  • High quality loudspeakers
  • Continuous vagus nerve monitoring during thyroid surgery
  • Integrated patient database
  • Barcode scanner for patient ID input


The C2 NerveMonitor was developed to provide real-time feedback for neural pathway integrity. Surgical procedures monitored using the C2 NerveMonitor include:

  • Thyroid gland procedures
  • Parotid surgery
  • Acoustic neuroma
  • Cochlear implantation
  • Pedicle screws and XLIF
  • Neurosurgery (motor cranial nerves)



Neuromonitoring for Spinal Column Surgery

C2 Spine Software – simple, fast and intuitive

inomed is pleased to announce the availability of our new Spine Software for the C2 NerveMonitor. The new Spine Software is coupled with a release of a set of matching accessories to enable easy and intuitive neuromonitoring during spinal surgery. The software is available on the C2 NerveMonitor platform, which is already used across the world for a wide range of surgical monitoring where user-friendly operation and quality signal acquisition is of paramount importance e.g. in thyroid surgery >>.

Intuitive controls –   positioning needle electrodes  and connecting cables

When monitoring spinal surgery with the C2 Spine Software, the user is guided step by step. The program provides simple options for setup ensuring the user is ready to perform the test very quickly.  The especially designed accessories have been adapted to the Spine Software. The user is guided intuitively through each step, starting from the correct positioning of the needle electrodes to connecting the cables to the system.  This makes neuromonitoring during spinal surgery an easy standard to adopt as a part of the surgical procedure. The C2 Spine Software combines efficient neuromonitoring during spinal surgery with simple and intuitive operation that has been tried and tested for other applications of the C2 NerveMonitor .

Automatic monitoring of the pharmacological relaxation status of patients

The C2 Spine Software includes an integrated twitch-test (relaxation monitoring). This test is used to automatically check the pharmacological relaxation status of the patient’s muscles. This is crucial for effective recording of signals during spinal surgery.

The muscles are continuously monitored when the software is in measuring mode. If a relevant activity occurs – for example, by direct nerve manipulation – the surgeon is informed of this visually and acoustically. Pedicle screw testing and stimulation capabilities of the C2 make automatic identification of the respective stimulation threshold value possible and thus the position of the screw within the pedicle can be inferred. Essential information is provided quickly and easily and is displayed for users during spinal surgery.

The C2 Spine Software automatically saves all muscle responses and stimulation limits in one document for the subsequent report. As a result, it is possible to review every stimulation response for the procedure at a later date.


  • Ease of operation by OR staff
  • Clear representation of the EMG signal
  • C2 Spine Software for operations on the spinal column
  • Good quality loudspeakers
  • Twitch-test for automatic relaxation monitoring
  • Barcode scanner for patient data


  • Posterior cervical interbody fusions
  • Lumbar interbody fusions

Ear, nose and throat medicine: Acoustic neuroma to the parotid

The application of neuromonitoring techniques can considerably reduce risks during parotid surgery

Surgery in ear, nose and throat medicine is delicate, complex and high-precision. This is also the case for surgery of the parotid (parotid gland surgery). During parotid surgery, the location of the branches of the facial nerve poses a major challenge for the surgeon. Monitoring, localization and function-testing of nerves located in the operating field is indispensable in supporting the surgeon during the parotid procedure. Neuromonitoring  serves as a method of choice, delivering lower risks and an improved patient outcome. The most common ENT interventions in which inomed products are used include the following:

  • Parotid surgery (surgery of the parotid gland)
  • Thyroid surgery
  • Acoustic neuroma
  • Tympanoplasty
  • Mastoidectomy

Monitor nerves, mitigate risk and improve patient outcome: Parotid gland surgery and other ENT procedures can be performed safely

During a parotid gland (parotid) procedure, the facial nerve is particularly at risk.

For thyroid surgery , neuromonitoring with inomed nerve monitoring technology can help  reduce the risk of nerve injury to the vocal cord nerves and thus minimize the possibility of  temporary or complete vocal cord paralysis.

During tympanoplasty procedures, neuromonitoring reduces the risk of injuring nerve tissue when milling near the boney facial canal. Additionally, during mastoidectomy procedures, neuromonitoring techniques are also used to reduce the risk of injury during milling in the vicinity of the bony facial canal.

Surgery in ear, nose and throat medicine is more challenging without the use of neuromonitoring equipment and techniques. Nerve-sparing parotid surgery (surgery of the parotid gland)improves the quality of intraoperative management and shortens operating times. Patients respond positively to the reduced surgical time leading to improved outcomes.
