The description focuses on traditional digital signal processing techniques like Fast Fourier Transform and feature extraction, without mentioning AI or ML.
No
The device is used to monitor the state of the brain by acquiring and processing EEG signals and is not described as providing any therapeutic or treatment function.
Yes
The device monitors the state of the brain by acquiring EEG signals and processing them to aid in monitoring the effects of anesthetic agents, which is a diagnostic purpose.
No
The device description explicitly states that the system configuration includes hardware components such as a monitor, digital signal converter (DSC), optional printer, cables, and electrodes. It also describes the monitor as microprocessor-based with signal processing and display capabilities, further indicating hardware involvement.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body (like blood, urine, tissue). This device directly monitors electrical activity within the brain (EEG signals) using electrodes placed on the skin.
- The intended use is to monitor the state of the brain and the effects of anesthetic agents. This is a physiological monitoring function, not a diagnostic test performed on a biological sample.
- The device description focuses on signal acquisition, processing, and display of real-time and processed EEG data. This aligns with a physiological monitoring device.
Therefore, the Aspect EEG Monitors with BIS are considered a physiological monitoring device, not an IVD.

Device Description
The Aspect Medical Systems, Inc. EEG Monitors, Models A-1000 and A-1050 with the processed parameter BIS, (hereafter referred to as the Aspect EBG Monitors with BIS) are microprocessor-based, up to 4 channel EEG monitors designed for use in the OR, ICU and for clinical research. They acquire and display real-time EEG waveforms, as well as process the real time EEG data using digital signal processing techniques including the Fast Fourier Transform technique, and display the processed EEG data in several different formats. The purpose of processing the EEG waveform data is to extract characteristic features from the complex signal in order to provide easier pattern recognition of changes over time during the recording. The system configuration includes a monitor, digital signal converter (DSC), optional printer, cables and electrodes. The EEG Monitors with BIS conform to UL 544, CSA 22.2 no. 125 Risk Class 3, IEC 601-1. They also meet electromagnetic interference specifications outlined in IEC 801-2,3,4,5.
