The summary explicitly states "Mentions AI, DNN, or ML: Not Found" and the description focuses on standard electrophysiological signal acquisition and analysis without mentioning any AI/ML components or capabilities.
No
The device is described as an electrodiagnostic system used for acquiring, displaying, analyzing, storing, reporting, and managing electrophysiological information to support the diagnosis of neuromuscular disease or condition, determine autonomic responses, and locate neural structures during surgery. It is not intended to provide therapy or treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is used "to support the diagnosis of neuromuscular disease or condition" and to "detect the physiologic function of the nervous system". Additionally, the "Device Description" section states that "The Nicolet EDX system is designed for the acquisition, display, analysis, reporting, and management of electrophysiological information from the human nervous and muscular systems," which is information commonly used in diagnosis, even if the device itself does not provide a "diagnostic conclusion."
No
The device description explicitly lists multiple hardware components as part of the system, including a base unit, amplifier, control panels, computer, display monitor, and various optional accessories like stimulators and a cart. While it includes application software, it is not solely software.
Based on the provided information, the Nicolet EDX is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- Nicolet EDX Function: The Nicolet EDX directly measures electrical activity within the human nervous and muscular systems. It acquires, displays, and analyzes physiological signals from the body itself, not from specimens taken from the body.
- Intended Use: The intended use clearly states it's for acquiring and analyzing electrophysiological information from the human nervous and muscular systems. It's used to detect physiological function and support diagnosis based on these direct measurements.
Therefore, the Nicolet EDX falls under the category of a medical device that performs physiological measurements, but it is not an In Vitro Diagnostic device.
