Neuromonitoring IOMAX

Cadwell New Cascade IOMAX

Intraoperative Neurophysiological Monitoring (IONM)

What is IONM? 

Surgeries are inherently risky, especially those that involve the brain, spinal cord or nerves. Intraoperative neurophysiological monitoring (IONM) is performed during many different types of surgeries to reduce the risk of devastating, irreversible neurological deficits, such as muscle weakness, loss of sensation, hearing loss and impairment of essential bodily functions.


IONM involves multi modal recording of electrical potentials from the nervous system during operations to detect adverse changes, enable corrective action, and offer surgical guidance.

The modular design of Cascade® IOMAX™ lets users tailor each IONM setup to the specific requirements of different surgeries. 

Cortical Module.

Designed for recording and stimulating at or near the patient’s head, provides 16 recording channels, TCS-9 for dynamic montaging of transcortical MEPs, and Low Current.

Auditory and Visual Stimulation. Optional extender pods provide flexible positioning.

Limb Module.

Designed for recording and stimulating the arms and legs with eight recording channels, 5 paired E-stim outputs, SpO2 and Heart Rate.

Base Module.

Provides power and communication via a single SafeT Cable to the OR table, and allows Trigger In/Out interfacing with third party devices.



Comprehensive switch matrix solution for direct cortical stimulation. Twelve outputs can be independently assigned as anode or cathode; includes two paired outputs for hand-held probes.

IOMAX systems are scalable from 8 to 48 channels  
  • Use the Cortical Module solo 
  • Combine the Cortical Module with 1 - 4 Limb Modules
  • Use one or two Limb Modules independently
