No
The document describes automated marking of EEG events ("seizure detection component" and "Burst-Suppression component") but does not explicitly mention the use of AI or ML algorithms for these functions. The description focuses on data acquisition, display, and basic analysis features.
No
The device is described as a "data acquisition device" used for recording and analyzing physiological signals (EEG, PSG) and patient video. Its output requires interpretation by a healthcare professional and is not intended to be diagnostic or therapeutic itself.
No
The "Intended Use / Indications for Use" section explicitly states, "In no way are any of the system functions represented as being in and of themselves diagnostic." It clarifies that the system's output "must be reviewed and interpreted by a physician or other trained health care professional who will exercise professional judgment in using this information."
No
The device description explicitly details various hardware components, including data acquisition devices (recorders/amplifiers), photic stimulators, video cameras, computer workstations, and carts, which are integral to the system's functionality. While software is a key part of the system, it is not a standalone software-only medical device.
Based on the provided information, the Harmonie System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Harmonie System Function: The Harmonie System acquires, displays, reviews, analyzes, and archives physiological signals directly from the patient (EEG, PSG, video). It does not analyze specimens taken from the body.
- Intended Use: The intended use clearly states the system is for acquiring and analyzing physiological signals and video obtained during examinations and studies. It explicitly states that the system functions are not diagnostic in themselves and require interpretation by a healthcare professional.
- Device Description: The description focuses on the acquisition and processing of electrical signals from the body and synchronized video.
While the system provides information that can be used by a healthcare professional to aid in diagnosis, it does not perform the diagnostic test on a specimen itself, which is the defining characteristic of an IVD.
N/A
Intended Use / Indications for Use
The Harmonie System is indicated for the acquisition, display, review, analysis and archiving of physiological signals including patient video obtained during routine EEG examinations, Long-Term Monitoring in Epilepsy (LTM) and Sleep Studies (polysomnography or PSG) in patients of all ages.
The seizure detection component of the software is intended for post-hoc review for marking sections of the EEG that may correspond to electrographic seizures in adults only. The Burst-Suppression component is intended to be used for the quantification and recognition (mark) of sections of the EEG and PSG that may contain patterns of interest. The seizure detection component and Burst-Suppression Module are for use in adults only.
The Harmonie software is not intended to replace conventional devices or methods used for sleep monitoring in critical care or intra-operative settings.
In no way are any of the system functions represented as being in and of themselves diagnostic. The system requires competent user input, and its output must be reviewed and interpreted by a physician or other trained health care professional who will exercise professional judgment in using this information.

Device Description
The Harmonie System is a data acquisition device that can record up to 128 channels of EEG and PSG signals at sample rates ranging from 200Hz to 2000Hz per channel according to the specifications of each model. EEG and PSG signals are amplified, filtered and digitized. A Photic Stimulator is optionally provided with the system. The system can also concurrently record synchronized digital patient video, through an optional MPEG4 encoder card and the DV software module. The digital data (EEG and digital video) is stored on the computer workstation's hard disk for review and analysis, either during or after a recording session.
Following is the functional description of various Harmonie models:
-
- Harmonie System with DUO Recorder
This is a basic EEG recording system, typically used for routine EEG examination. The DUO recorder is a 20-bit, 44-channel amplifier with user programmable filters, automatic anti-aliasing and sampling rates of up to 2,000 Hz. All components are mounted on a robust enclosed cart, which can accommodate a Photic Stimulator and various models of CCTV cameras, as accessories. The system includes Harmonie EEG software that allows acquisition, display, review, analysis and archiving of EEG data locally or at a remote station.

-
- Harmonie-S System with DUO Recorder
The Harmonie-S system uses same DUO recorder described above but uses PSG software to record sleep studies. It includes optionally digital video recording. The amplifier and video camera are placed in the room. The computer and monitor are placed in an observation room where the PSG technologist works. The software includes the Harmonie EEG and the PSG modules. The PSG module is designed specifically for the visualization and scoring of variables commonly used in sleep studies, such as the EEG, EMG, EKG, oxygen saturation, body position, eye movements and respiration signals. The system allows performing the main functions of a sleep study: sleep staging, manual event marking, displaying graphs of sleep stages and events, and various sleep report generation.

MESA-II is a portable system suitable for EEG examinations, also using the DUO EEG amplifier. It offers the full functionality of the standard Harmonie system, but with a laptop computer and other components mounted on a cart with a smaller foot-print, which enables EEG examinations to be performed in space-limited environments. The cart can accommodate a Photic Stimulator and various models of CCTV cameras, as accessories. The system includes Harmonie EEG software that allows acquisition, display, review, analysis and archiving of EEG data locally or at a remote station. -
Vita ICU System with DUO Recorder 4.
The Vita ICU system is an EEG recording system designed to facilitate EEG recordings in the ICU, although it can also be used as a routine EEG system. It includes optionally digital video recording. The Vita ICU system is composed of a panel PC (computer and monitor in the same physical entity), including a touch-screen monitor, and is mounted on small footprint cart. It includes the Harmonie EEG software as well as software specific for this application (the Vita ICU software). The Vita ICU software includes a touch-screen interface to facilitate user-interaction with the device. -
- Harmonie-E System with eAmp Recorder
The Harmonie-E system with eAmp recorder is an EEG recording system designed for LTM particularly in the context of the evaluation of patients with epilepsy. The eAmp is an IP-enabled amplifier with the capability to acquire data for up to 128 channels (by combining two 64-channel units). It includes programmable filters from 0.1 to 500Hz and sampling rates up to 2,000Hz that allow measurement of higher frequency EEG. The system includes digital video recording. The amplifier and video camera are placed in the room and the recording computer and monitor and placed in a control room. The system includes Harmonie EEG software that allows acquisition, display, review, analysis and archiving of EEG data locally or at a remote station.
