AI/ML Overview

The provided text describes the Pascall Systems, Inc. Wireless EEG System and its substantial equivalence to predicate devices, but it does not contain a specific study demonstrating direct acceptance criteria for an AI/algorithm's performance. Instead, it focuses on the device's overall performance as an EEG system against established medical device standards and a comparison to predicate devices, particularly regarding its functional components and display features.

However, the document does mention testing related to the "Burst Suppression Ratio" (BSR) which involves a comparison to "manual review of the raw EEG timeseries." This can be interpreted as a form of algorithm performance evaluation.

Here's an attempt to extract and synthesize the information based on your request, focusing on the BSR "study" as the most relevant part, and acknowledging the limitations in the provided text:

Study and Acceptance Criteria Description (Focused on Burst Suppression Ratio - BSR)

The Pascall Systems, Inc. Wireless EEG System underwent non-clinical bench performance testing, which included a specific test to establish substantial equivalence of its Burst Suppression Ratio (BSR) output.

1. Table of Acceptance Criteria and Reported Device Performance

Performance CharacteristicAcceptance CriteriaReported Device Performance & Results
Burst Suppression Ratio< 5% difference from manual review for 100% agreementAll runs of the 49 segments passed the acceptance criteria, demonstrating a 100% level of agreement (meaning < 5% difference from manual review).

2. Sample Size Used for the Test Set and Data Provenance

  • Test Set Sample Size: 49 segments of EEG signals from 10 patients.
  • Data Provenance: Not explicitly stated (e.g., country of origin). The data is implicitly retrospective as it involved "segments of EEG signals from 10 patients."

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications

  • Number of Experts: Not specified.
  • Qualifications of Experts: Not specified, but the ground truth was "manual review of the raw EEG timeseries," implying review by qualified professionals (likely neurologists or neurophysiologists experienced in EEG interpretation, though not explicitly stated).

4. Adjudication Method for the Test Set

  • Adjudication Method: Not explicitly stated. However, since the ground truth was "manual review," it implies direct human interpretation rather than a multi-reader consensus method like 2+1 or 3+1. It's possible a single expert or an unspecified number of experts performed the "manual review."

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

  • Was it done?: No. The document does not describe an MRMC study comparing human readers with and without AI assistance. The testing focuses on the device's internal performance against a manual ground truth.

6. Standalone (Algorithm-Only) Performance Study

  • Was it done?: Yes, for the Burst Suppression Ratio (BSR) calculation. The device's algorithm for BSR was tested by "repeatedly inputting 49 segments of EEG signals" and comparing its output to "manual review." This represents a standalone performance evaluation of the BSR computation. The validation of the real-time Spectrogram, Phase-Amplitude display, and EMG Index using "known simulated input signals" also constitutes a standalone performance evaluation of these specific algorithms/outputs.

7. Type of Ground Truth Used

  • Ground Truth Type: Expert consensus/manual review (specifically, "manual review of the raw EEG timeseries" for BSR). For other outputs like Spectrogram, Phase-Amplitude, and EMG Index, "known simulated input signals" were used, which acts as a defined ground truth.

8. Sample Size for the Training Set

  • Training Set Sample Size: Not specified. The document does not provide details about a training set, implying that either the device's algorithms are not machine learning-based in a way that requires explicit training data disclosure in this context, or that information was not deemed necessary for this 510(k) summary.

9. How the Ground Truth for the Training Set Was Established

  • Ground Truth Establishment for Training Set: Not applicable as a training set is not described.

Summary of Device Performance (General)

Beyond the specific BSR study, the document broadly describes the Pascall Systems, Inc. Wireless EEG System's performance in comparison to predicate devices and relevant standards:

  • Non-Clinical Bench Performance Testing: The system was tested in accordance with performance standards for electroencephalographic devices (IEC 60601-1, IEC 60601-1-2, IEC 80601-2-26, ISO 10993 Parts 5 and 10).
  • Test Objectives: To verify claimed ranges of measurement, essential performance requirements (amplitude/rate accuracy, dynamic range, noise, frequency response, common mode rejection).
  • Test Methods: Bench testing on end-to-end systems with simulated input.
  • Pass/Fail Criteria: Compliance with claimed range and precision in labeling.
  • Results Summary: The system met all applicable specifications and was found substantially equivalent to the predicate device.
  • Biocompatibility: Patient-contacting materials passed ISO 10993 tests for cytotoxicity, skin sensitization, and skin irritation.

Overall Conclusion from the document: The Pascall Systems, Inc. Wireless EEG System is substantially equivalent to the predicate device based on review of test results and comparison of characteristics and specifications.

Summary of Substantial Equivalence:

The intended use of the primary predicate device and the Pascall Systems, Inc. Wireless EEG are substantially equivalent. Both systems are intended to monitor the brain by real-time data acquisition and processing of electroencephalograph signals in adult patients 18 years of age or older. Both systems are intended to be used in the operating room, post-anesthesia recovery unit, intensive/critical care unit. The primary predicate device includes use in clinical settings, at home and for clinical research. The subject device does not claim use in these areas but does specify inpatient and outpatient surgery settings. This difference in the environment of use is not considered significant and do not affect safety or effectiveness.

Both systems use an electrode array and sensor/amplifier to detect and communicate the electroencephalograph to a PC display unit that provides raw EEG waveforms and a digital spectral analysis presentation to a clinical user. Both systems use a reduced montage of 4 electrodes to obtain 4 EEG channels. The Pascall Systems, Inc. includes a reference electrode and ground electrode (total of 6 electrodes) while the primary predicate device uses a 5th electrode as a reference.

Both systems provide signal quality indications including electrode impedance measurements to alert the user of poor electrode contact for each EEG channel which can indicate the signal is suspect. Both systems measure and display artifact. The primary predicate device displays Artifact Detection Flags and Noise Level. The subject device displays an Artifact Index that is intended to represent noise associated with the use of an electrosurgical unit. The primary predicate device performs a pre-processing on the EEG that includes artifact removal. The subject device performs band-pass filtering pre-processing but does not perform further artifact filtering and displays the artifact index based on the raw signal that is contained within the band-pass of the system. The difference in these data presentations does not affect safety and effectiveness as both devices provide an equivalent display of signal quality to alert the user.

Both systems are not intended to be the sole basis for diagnosis or therapy decisions but are used in conjunction with other clinical signs, data, and symptoms. Both systems display the raw EEG waveforms. The primary predicate device requires a wireless option to transmit the data for display on the Data Viewer while the subject device uses wireless functionality to transmit this data on a continuous basis to a tablet for display.

Both systems display a spectrogram and indicate spectral edge frequency along with the display of the quality indicators for artifact, electrode impedance, and EMG. The primary predicate device presents the spectral edge frequency as 50% Median Edge Frequency and 95% Spectral Edge Frequency (SEF) while the subject device displays Spectral Edge Frequency of 95% and a marker at 10 and 20 Hz on the 0 - 30 Hz scale provided as an aid to help identify the frequency components of the spectrogram.

The subject device and the secondary predicate device both display a presentation of burst suppression. The secondary predicate device displays the data as a burst suppression ratio over a given time period. This is the ratio of measurable EEG signal above a stated threshold, and the suppressed EEG signal that is below the stated threshold. The subject device displays burst suppression probability which is the probability that suppression varies smoothly in time and measures only those frequencies that are within a certain range. These differences are not significant and do

{6}------------------------------------------------

not affect safety and efficacy as both devices present a means of determining suppression percentage.

The subject device also displays phase-amplitude modulogram which is not displayed by either of the predicate devices. The phase-amplitude modulogram is a color-intensity display that help visualize the relationship between the amplitude of the highfrequency components of the EEG and the phase of the low-frequency components in the EEG signal. This display provides an additional tool for the medical professional and does not affect safety and effectiveness of the subject device.

The skin contacting components of both the primary predicate device and the subject device are made of materials that meet the ISO 10993 standards for cytotoxicity, skin irritation, and skin sensitization.

Technology Comparison:

The Pascall Systems, Inc. Wireless EEG System employs similar technological characteristics to the predicate devices.
