More Information

Not Found

No
The device description details hardware components and basic signal processing capabilities typical of an older generation electroencephalograph and evoked potential system. There is no mention of AI, ML, or advanced algorithms for data analysis or interpretation.

No
The device is indicated for detection and display of electrical activity, not for treatment.

Yes

The "Intended Use / Indications for Use" states that the device is "indicated for use in the detection and display of evoked responses of electrical activity of the brain and the peripheral nervous system," which directly describes a diagnostic function.

No

The device description explicitly details numerous hardware components including an ACQ board, stimulators (acoustic, visual, and electric), and their specifications (size, weight, power supply, etc.). This indicates it is a hardware device with associated software, not a software-only device.

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

Here's why:

  • Intended Use: The intended use is "in the detection and display of evoked responses of electrical activity of the brain and the peripheral nervous system." This describes a device that measures physiological signals directly from the patient's body.
  • Device Description: The description details components for stimulating and recording electrical activity (EEG, evoked potentials) and sensory responses (acoustic, visual, electric). These are all methods for interacting with and measuring the body's responses, not for analyzing samples taken from the body.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or performing tests in vitro (outside the living body).

IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic purposes. This device operates by directly interacting with and measuring the electrical activity of the nervous system in vivo.
