Neurodata Amplifier System
Device Description
The Model 15 combines up to 32 of the P511 amplifier circuits (in banks of 4) in a single enclosure and replaces the P511 manual switches with solid-state switches that are controlled via a standard RS-232 serial port. The Model 15 relies on the essential safely features of the P511 amplifier capacity-coupled patient circuit and safety-extra-low-voltage operation (12VDC) and improves on the safety of the P511 by isolating the patient applied circuits from the enclosure (earth).

No
The summary describes a hardware amplifier system with solid-state switches controlled via a serial port, focusing on electrical safety features. There is no mention of AI, ML, or any data processing that would suggest such technology.

No
The document describes an amplifier system that processes neurodata, but there is no information indicating it is used for treating or diagnosing any medical condition.

No
The "Intended Use / Indications for Use" section states "Neurodata Amplifier System", which suggests it amplifies neurodata rather than interpreting it for diagnostic purposes. There is no mention of diagnostic claims or intended medical diagnosis.

No

The device description explicitly mentions hardware components like "amplifier circuits," "enclosure," "solid-state switches," and "RS-232 serial port." It also describes electrical characteristics like "safety-extra-low-voltage operation (12VDC)" and "isolating the patient applied circuits from the enclosure (earth)." This indicates it is a hardware device with software control, not a software-only device.

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

Here's why:

  • Intended Use/Indications for Use: The description mentions a "Neurodata Amplifier System" and "patient circuit." This strongly suggests the device is used to amplify physiological signals from a patient, likely for diagnostic or monitoring purposes on the patient.
  • Device Description: The description details an amplifier system designed to connect to a patient ("patient applied circuits"). This is characteristic of devices used for direct physiological measurement, not for testing samples in vitro (outside the body).
  • Lack of IVD Indicators: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any processes typically associated with in vitro diagnostics.

Therefore, the device described is likely a physiological signal amplifier used for clinical purposes, not an IVD.

This product is similar in design and function to the Grass ® Model P511 and Melville Diagnostics MMC Series amplifier systems

The intended use and essential design, performance, and safety characteristics of the Model 15 are the same as the Grass Model P511 amplifier, a single-channel amplifier with manual control of all settings. The Grass P511 has been in production since 1968 and is still in current production and listed with the FDA. The Model 15 combines up to 32 of the P511 amplifier circuits (in banks of 4) in a single enclosure and replaces the P511 manual switches with solid-state switches that are controlled via a standard RS-232 serial port. The Model 15 relies on the essential safely features of the P511 amplifier capacity-coupled patient circuit and safety-extra-low-voltage operation (12VDC) and improves on the safety of the P511 by isolating the patient applied circuits from the enclosure (earth).
