Intended Use
The Cascade IOMAX™ Intraoperative Monitor with Surgical Studio software (IOMAX) is an electroneurodiagnostic device that acquires, displays and stores physiologic data from peripheral sensory and motor nerves, muscles and the central nervous system, generated either spontaneously or elicited stimuli. The acquired data are necessary to perform somatosensory. auditory and visual evoked potentials (EPs), electroencephalography (EEG), electromyography (EMG), transcranial motor evoked potentials (TcMEPs), direct cortical stimulation, nerve conduction studies and Train of Four (TOF) analysis. SpO2 measures and displays oxygen saturation and heart rate information. The system also delivers direct nerve stimulation required for specific surgical procedures. Evoked Potentials (EPs): IOMAX provides electrical, auditory or visual stimulation and measures, and stores the electrical activity of the nervous system in response to the stimulation. EEG: IOMAX measures, displays, records, and stores electrical activity of the brain from two or more electrodes on the head. Free Run EMG: IOMAX acquires, displays, records, and stores spontaneous EMG activity of motor nerves by continually displaying a live stream of mechanically induced myotome contractions. TcMEP: IOMAX delivers transcranial stimulation via dedicated outputs for intraoperative assessment. Cortical Stimulation: IOMAX delivers Low Current Stimulation (LCS) during surgical procedures to map various areas of the cortex. Triggered EMG (TEMG): IOMAX electrically stimulates the motor nerves, and displays, records, and stores the resulting compound muscle action potentials in the innervated muscle. Nerve Conduction Study (NCS): IOMAX measures, displays, records, and stores sensory and motor nerve conduction time (latency) by applying a stimulus to peripheral nerves, the spinal cord, and the central nervous system. Train of Four (TOF) or Twitch Test: IOMAX delivers a train of four pulses and measures, and stores the compound muscle action potential amplitude fade for analysis. SpO2: IOMAX measures and displays oxygen saturation and heart rate information. Remote Reader: IOMAX provides passive, real time remote review of intraoperative monitoring for a physician outside of the operating room. IOMAX is used by or under the direction of a licensed physician, surgeon, or neurologist in a professional healthcare facility environment for pre-operative, intraoperative and post-operative testing.

It consists of Cadwell custom hardware, a standard laptop or desktop personal computer (PC) running a standard off-the-shelf (OTS) operating system (OS), and Cadwell custom software. The modalities recorded, measured and displayed by the IOMAX are: - . Evoked potential (EP) in the form of: - Brainstem auditory (BAEP): O - Visual (VEP); and O - Somatosensory (SSEP). O - Transcranial electrical motor evoked potential (TcMEP). - Electromyography (EMG). ● - Triggered EMG. - Electroencephalogram (EEG). ● - Nerve conduction studies. - Train of four (TOF). ● - SpO2 and heart rate values. ● - Threshold mode. ● - Cortical stimulation.
More Information

No
The summary describes a standard intraoperative neuromonitoring system that acquires, displays, and stores physiological data. There is no mention of AI or ML in the intended use, device description, or performance studies. The device performs standard signal processing and analysis techniques common in this field.

No
The device is described as an "electroneurodiagnostic device" that acquires, displays, and stores physiological data. Its intended use is for monitoring and diagnosing, not for treating or curing a condition.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states "The Cascade IOMAX™ Intraoperative Monitor with Surgical Studio software (IOMAX) is an electroneurodiagnostic device that acquires, displays and stores physiologic data..." Furthermore, it lists various physiological measurements and tests (e.g., EPs, EEG, EMG, NCS) that are diagnostic in nature, used for assessing the function of the nervous system.

No

The device description explicitly states that the IOMAX system consists of "Cadwell custom hardware" in addition to software and a standard PC. This indicates it is not a software-only medical device.

Based on the provided information, the Cascade IOMAX™ Intraoperative Monitor with Surgical Studio software is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • IOMAX Function: The IOMAX is an electroneurodiagnostic device that directly measures and displays physiological data from the patient's nervous system and muscles in vivo (within the living body). It uses electrodes and stimulation applied to the patient, not analysis of samples taken from the patient.

The intended use and device description clearly indicate that the IOMAX is used for intraoperative monitoring and testing of the nervous system and muscles directly on the patient during surgical procedures. This is distinct from the function of an IVD device.
