ISIS IOM System

    The ISIS IONM system is available in three different forms – the ISIS IONM system, the ISIS IONM compact system, and the ISIS IONM Xpress (portable). The type and number of amplifiers can be selected and configured in accordance with the user’s intended application. The ISIS neurostimulator is the heart of every ISIS IONM system.

The stimulation adapters used with the ISIS neurostimulator are color-coded and clearly labelled, enabling easy connection to probes and electrodes at the patient’s bedside.

Regardless of the ISIS IONM system you choose – all IONM system configurations are based on USB technology and are designed to be upgradable. The systems can be enhanced with additional channels and applications as required to meet your changing monitoring needs.


  • The ISIS IONM system is available as an 8, 16, 24 or 32 channel system and can be upgraded up to 128 channels, if required
  • Constant current stimulator with 12+1 outputs for direct neural, cortical, muscular, transcutaneous and transcranial electrical stimulation
  • Stimulation current of 0.01mA to 250mA can be set at individually definable levels
  • Continuous impedance measurement and current flow control indicator
  • Each stimulation channel can be used flexibly for all measurement types and freely selected to create montages or muscle groups
  • Easily create an unlimited number of application-specific, pre-installed measurement programs. The system includes a large number of predefined programs for application areas, including tibialis, EMG, SEP, MEP and SEP
  • Simultaneous, clear presentation of all measurement types, including tables, stacks and trends for selected modalities
  • Patient documentation database with the option to synchronously analyse data from another PC


  • Neurosurgery, including SEP and MEP monitoring during spinal cord surgery
  • ENT surgery, including AEP and EMG monitoring in acoustic neuroma
  • General & visceral surgery, for example, EMG monitoring in surgery of the thyroid gland
  • Vascular surgery, for example, SEP monitoring in the event of carotid stenosis
  • Orthopaedics and spinal surgery, such as SEP and MEP monitoring spine and scoliosis surgery
  • Cardiothoracic surgery, such as SEP and MEP monitoring for aortic aneurysms
  • Pelvic Intraoperative Neuromonitoring
