More Information

No
The summary describes a system for intraoperative neuromonitoring using standard signal processing techniques (evoked potentials, EEG, EMG, etc.) and does not mention any AI or ML components in the device description, intended use, or performance testing.

No
The "Intended Use / Indications for Use" section explicitly states that the product is for "non-therapeutic clinical use."

Yes

The device is used for "intraoperative monitoring and testing" and "to examine neuronal tissue by recording and stimulation" using various measurement modalities like EEG, EMG, and evoked potentials. This process of collecting data to assess the state of the nervous system is a diagnostic function.

No

The device description explicitly states that the system consists of "custom stimulation and recording hardware" in addition to the software. The performance testing also includes verification and validation of the hardware components (ISIS Headboxes and ISIS Neurostimulator).

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the product is used for "intraoperative monitoring and testing during surgical procedures" to "examine neuronal tissue" by recording and stimulation. This involves directly interacting with the patient's nervous system in vivo.
  • Device Description: The device description details hardware for stimulation and recording, a computer, and software. This aligns with a system used for physiological monitoring and stimulation in vivo.
  • Lack of IVD Characteristics: IVD devices are designed to examine specimens derived from the human body (like blood, urine, tissue samples) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. This device does not process or analyze such specimens.

The device is a medical device used for neuromonitoring and stimulation during surgery, which is an in vivo application.
