No
The document does not mention AI, DNN, or ML, and the description of the device and its processing capabilities does not suggest the use of these technologies. The processing described is standard EEG analysis (power spectrum, spectral parameters, EEG stage, Narcotrend Index).
No
The device is an EEG monitor that registers and displays EEG signals to monitor the state of the brain. It is used as an aid in monitoring the effects of certain anesthetic agents, but it does not directly treat or provide therapy.
Yes
The device monitors the state of the brain by registering and displaying EEG signals, and the Narcotrend Index, a processed EEG parameter, is used as an aid in monitoring the effects of certain anesthetic agents. This falls under diagnostic purposes.
No
The device description explicitly lists hardware components such as a Preamplifier, Monitor, System lead, and Patient lead, indicating it is not a software-only device.
Based on the provided information, the Narcotrend EEG monitor is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. The Narcotrend directly measures electrical activity from the brain (EEG signals) through electrodes placed on the skin. It does not analyze biological samples.
- The intended use describes monitoring the state of the brain and the effects of anesthetic agents. This is a direct physiological measurement and monitoring function, not an analysis of a biological specimen.
Therefore, the Narcotrend falls under the category of a physiological monitoring device, not an IVD.

Device description
The Narcotrend is a stand-alone EEG monitor including the following components:
- · Preamplifier
- · Monitor for data analysis and display
- . System lead (connects preamplifier and monitor)
- · Patient lead (connects the electrodes with the preamplifier)
The Narcotrend records and processes data of one or two channels of EEG. The monitor display includes the following:
- · Raw EEG
- · Power spectrum
- · Processed EEG parameters including spectral parameters, EEG stage, and the Narcotrend Index (current values and trend plots)
Intended use
The EEG monitor Narcotrend serves the purpose of registering and displaying EEG signals and thus monitoring the state of the brain.
It was developed specifically for use in operating rooms, intensive care units, and for clinical research.
The Narcotrend includes the Narcotrend Index, a processed EEG parameter which may be used as an aid in monitoring the effects of certain anesthetic agents.
Summary of technological characteristics compared to predicate device
The Narcotrend and the predicate device are similar in the following ways:
- · Both devices record and display the EEG.
- · Both monitors provide processed EEG parameters including a numerical EEG index which serves as an aid in assessing the hypnotic effects of certain anesthetic agents.
- · Both devices conduct self-tests and electrode checks (automatic and manual).
- · Both devices have capabilities for marking events and reviewing stored data.
- · Both devices have capabilities for printer support and data transfer via RS232 serial port.
- · Both systems have two main components, a monitor and a preamplifier.
The Narcotrend and the predicate device are different in the following ways:
- · The Narcotrend is operated via touch screen while the predicate device is operated via keys.
- · The Narcotrend includes a high resolution color monitor while the predicate device has a monochrome monitor.
2
- · By default, the Narcotrend uses standard single-use ECG electrodes while the predicate device uses specially designed EEG sensors placed on the forehead.
- · The Narcotrend can record and display two channels of EEG while the predicate device uses one channel of EEG.
Summary of nonclinical testing for the device
The Narcotrend complies with the safety standards below and is therefore safe and effective for the intended use. The device has been thoroughly tested including electrical safety, electromagnetic compatibility, mechanical and environmental tolerance, software validation and verification of specifications. Verification with the following mandatory and voluntary standards and guidelines has been made:

Dear Mr. Wieland:
This letter corrects our substantially equivalent letter of September 17, 2004.
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
