No
The description focuses on signal processing and monitoring of physiological responses to electrical and mechanical stimuli, with no mention of AI or ML algorithms for data analysis or interpretation.
No
The device is used to assist in locating and mapping motor nerves during surgery, which is a diagnostic and surgical assistance function, not a direct therapeutic intervention.
Yes
The device assists in locating and mapping motor nerves and identifies spinal nerve roots and peripheral motor nerves, which are diagnostic functions. It records MMG signals and alerts the surgeon to activated nerves, providing information to minimize trauma. While used intraoperatively, its primary role is to diagnose the location and status of nerves.
No
The device description explicitly states that the NeuralMAS™ system consists of a reusable Patient Module, a Control Unit comprised of a touch-screen PC, and an assortment of disposable conductive probes, stimulators, sensors, electrodes, and electrode leads. These are all hardware components, indicating it is not a software-only device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- This device is used in vivo (within a living organism) during surgical procedures. It directly interacts with and measures signals from the patient's nerves and muscles.
- The intended use and device description clearly state its purpose is to assist in locating and mapping motor nerves during surgery by recording signals from muscles and applying electrical stimulus.
Therefore, the NeuralMAS™ system falls under the category of a medical device used for intraoperative monitoring, not an in vitro diagnostic device.

Device Description
The NeuralMAS™ system is a multichannel intraoperative monitor for use during surgeries in which a motor nerve is at risk. The NeuralMAS™ system records mechanomyographic (MMG) signals from muscles innervated by the affected nerve, which may originate from operator applied electrical stimulus or from direct or indirect mechanical stimulus occurring during the course of surgery. The monitor will assist early nerve identification by providing the surgeon with a tool to help locate and identify the particular nerve at risk to minimize trauma by alerting the surgeon when a particular nerve has been activated.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
A comparative performance evaluation was conducted in the sheep to assess statistical agreement between the subject device and the predicate. Results for positive, and overall percent agreement have established that 1) the principle functions of the NeuralMAS™ system are effective, such that spinal nerve status and location may be ascertained and monitored, and 2) the data acquired by the subject device during simulated surgical use in the animal model correlate well with those acquired simultaneously by a predicate device.

Not Applicable
10. Conclusions:
The conclusions drawn from our non-clinical testing (to include our animal testing) of the subject device demonstrates that the subject device is as safe, as effective and performs as well as the legally marketed predicate device. The subject device is substantially equivalent in function to the legally marketed predicate device.
