Intended Use

LVIS NeuroMatch Software is intended for the review, monitoring and analysis of electroencephalogram (EEG) recordings made by EEG devices using scalp electrodes and to aid neurologists in the assessment of EEG. The device is intended to be used by qualified medical practitioners who will exercise professional judgement in using the information. The Seizure Detection component of LVIS NeuroMatch is intended to mark previously acquired sections of adult EEG recordings from patients greater than or equal to 18 years old that may correspond to electrographic seizures, in order to assist qualified medical practitioners in the assessment of EEG traces. EEG recordings should be obtained with a full scalp montage according to the electrodes from the International Standard 10-20 placement. The Spike Detection component of LVIS NeuroMatch is intended to mark previously acquired sections of adult EEG recordings from patients >18 years old that may correspond to spikes, in order to assist qualified medical practitioners in the assessment of EEG traces. LVIS NeuroMatch Spike Detection performance has not been assessed for intracranial recordings. LVIS NeuroMatch includes the calculation and display of a set of quantitative measures intended to monitor and analyze EEG waveforms. These include Artifact Strength, Asymmetry Spectrogram, and Fast Fourier Transform (FFT) Spectrogram. These quantitative EEG measures should always be interpreted in conjunction with review of the original EEG waveforms. LVIS NeuroMatch displays physiological signals such as electrocardiogram (ECG/EKG) if it is provided in the EEG recording. The aEEG functionality included in LVIS NeuroMatch is intended to monitor the state of the brain. LVIS NeuroMatch Artifact Reduction (AR) is intended to reduce muscle and eye movements, in EEG signals from the International Standard 10-20 placement. AR does not remove the entire artifact signal and is not effective for other types of artifacts. AR may modify portions of waveforms representing cerebral activity. Waveforms must still be read by a qualified medical practitioner trained in recognizing artifacts, and any interpretation or diagnosis must be made with reference to the original waveforms. This device does not provide any diagnostic conclusion about the patient's condition to the user.

Device Story

NeuroMatch is a cloud-based SaMD for reviewing, monitoring, and analyzing previously acquired or near real-time EEG data. Input consists of EEG recordings (10-20 scalp montage) and optional ECG signals. The device uses deep learning algorithms to perform artifact reduction, seizure detection, and spike detection, and calculates quantitative measures (FFT, spectrograms, aEEG). Output is displayed to neurologists/qualified practitioners as annotated EEG traces and quantitative metrics. The device does not provide diagnostic conclusions; clinicians must interpret outputs in conjunction with original waveforms. It assists in identifying potential electrographic seizures and spikes, potentially improving clinical efficiency in EEG review and patient monitoring.

Clinical Evidence

Clinical validation used independent datasets from three institutions. Seizure detection (N=191 subjects, 1059.4 hours) showed 75.01% sensitivity and 3.74 FDR/24hr, meeting non-inferiority criteria against Persyst 14. Spike detection (N=149 subjects, 45.9 hours) showed 72.18% sensitivity and 3.24 FDR/min, meeting non-inferiority criteria. Reference standards were established by a panel of three neurologists using a 2/3 majority rule. Testing confirmed non-inferiority in both sensitivity and false detection rates.

Technological Characteristics

Cloud-based SaMD; utilizes deep learning-based algorithms for event detection. Compatible with standard 10-20 scalp EEG electrode placement. Provides quantitative EEG measures (FFT, spectrograms, artifact strength) and artifact reduction. Operates on previously acquired or near real-time EEG data. No hardware components; software-only.

Indications for Use

Indicated for review, monitoring, and analysis of EEG recordings in adults (≥18 years) using scalp electrodes (10-20 system). Includes seizure and spike detection, quantitative EEG measures (Artifact Strength, Spectrograms, FFT), aEEG, and artifact reduction. Intended for use by qualified medical practitioners to aid in EEG assessment. Not for intracranial recordings.
