BrainScope® Ahead® 200 is a Brain Injury Adjunctive The Interpretive Electroencephalograph Assessment Aid, Class II device. It is a portable, non-sterile, non-invasive, non-radiation emitting, point of care, electroencephalogram (EEG) device and is intended to provide an objective assessment of brain electrical activity associated with traumatic brain injury (TBI). This brain injury adjunctive interpretive EEG assessment aid is for use as an adjunct to standard clinical practice only as an assessment aid for a medical condition for which there exists other valid methods of diagnosis.
The BrainScope® Ahead® 200 is comprised of two hardware components: the Handheld Device and the disposable Electrode Headset with patient application supplies. The main software components of the Ahead 200 are the application software and the BrainScope Algorithm Library (BSAL). The Ahead® 200 has two models: (1) the Ahead® M-200, which is intended for use by the military, and (2) the Ahead® CV-200, which is intended for civilian use. The Ahead® M-200 and the Ahead® CV-200 have the same indications for use and intended uses with the exception that the Ahead® M-200 model additionally stores and displays an electronic version of the Military Acute Concussion Evaluation (MACE) and user-entered responses to the MACE questions. There is no interaction between EEG-related functionality, including analyzing and displaying brain electrical activity, and the function of storing and displaying MACE information. The Ahead® M-200 and the Ahead® CV-200 have identical technological characteristics except that the Ahead® M-200 contains the additional MACE feature, i.e., an electronic version of the paper and pencil based MACE.
This document is a 510(k) premarket notification for the BrainScope Ahead 200 device, asserting its substantial equivalence to a predicate device, the BrainScope Ahead 100. It focuses on device specifications, safety, and performance comparisons rather than detailed clinical acceptance criteria and a definitive study demonstrating them.
Here's an analysis based on the provided text, outlining the limitations due to the nature of the document:
1. A table of acceptance criteria and the reported device performance
The document does not explicitly state "acceptance criteria" in terms of clinical performance metrics (e.g., sensitivity, specificity, AUC) for the Ahead 200 device. Instead, it focuses on verifying that the Ahead 200 functions as intended and is comparable to its predicate device. The performance data presented are primarily engineering and safety tests:
| Design Verification Test | Result |
|---|---|
| Software (including User Interface) Verification Testing | Pass |
| Hardware Verification | Pass |
| System Performance and Functionality | Pass |
| Algorithm Performance | Pass |
| Packaging Testing | Pass |
| Basic Safety and Essential Performance (IEC 60601-1, 3rd ed.) including PEMS clause 14 for Software | Pass |
| Electromagnetic Compatibility | Pass |
| Biocompatibility | Pass |
| Reliability | Pass |
The document asserts the "Algorithm Performance" passed, and that the "Harmony" classification algorithm used is the same as the predicate device, implying its performance is at least equivalent. However, specific performance metrics (sensitivity, specificity) of this algorithm are not provided in this document.
Similarly, electrical hardware specifications are compared, suggesting functional acceptance criteria for components:
| Electrical Hardware Feature | Ahead® 200 Performance | Comparable Predicate Ahead® 100 Performance | Note (Indicating improvement or equivalence) |
|---|---|---|---|
| Common Mode Rejection Ratio (CMRR) | < -100 dB | < - 85 dB | Ahead® 200 better CMRR |
| Low pass filtering prior to signal processing | 0.3 Hz to 43Hz | 0.3 Hz to 43Hz | Same |
| System Noise Floor | < 0.4 µV in 0.3 Hz to 43Hz bandwidth | < 0.4 µV in 0.3 Hz to 43Hz bandwidth | Same |
| ADC Resolution | 45 nV/bit | 31.2nV/bit | Both devices have better resolution than their noise floor |
| ADC Sampling Rate | 1000 Hz, down sampled to 100 Hz for algorithm processing | 1000 Hz, down sampled to 100 Hz for algorithm processing | Processing bandwidth used by algorithm is same |
| Data Channel | 7 | 7 | Same |
The clinical "acceptance criteria" for the device, in terms of diagnostic accuracy, would typically have been established during the clearance of the predicate device (Ahead 100), as this submission for Ahead 200 claims "substantial equivalence" based on using the "Same Harmony algorithm" and "Same fundamental technology." This document does not present a new clinical study to establish these criteria for the Ahead 200 itself.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the document for the clinical performance of the classification algorithm. The document states that "All tests were conducted on the new model to establish substantial equivalence to the predicate (Ahead® 100, models M-100 and CV-100, DEN 140025)." These are primarily engineering and functionality tests. Any clinical performance data regarding the "Harmony" algorithm would likely be referenced in the predicate device's 510(k) (DEN 140025), which is not part of this input.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not provided in the document as it focuses on engineering and functional testing for equivalence. For the clinical performance of the classification algorithm, ground truth (e.g., presence/absence of structural brain injury on head CT) would have been established for the studies that supported the predicate device's clearance.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not provided in the document.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
There is no mention of an MRMC comparative effectiveness study in this document. The device is a "Brain Injury Adjunctive Interpretive Electroencephalograph Assessment Aid," meaning it's intended to aid in evaluation, not directly replace or be compared in an MRMC setting with human readers. It's an algorithm generating a "classification" based on EEG, which is then used by a physician.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
The document mentions "Algorithm Performance" as a test that passed. The "BrainScope® Classification" (positive/negative) output by the device is described as "brain electrical activity consistent with no structural brain injury visible on head CT" or "brain electrical activity that may be present in both patients with or without a structural brain injury visible on head CT." This implies a standalone classification from the algorithm. However, quantitative performance metrics (e.g., sensitivity, specificity, PPV, NPV) of this standalone classification are not explicitly provided in this document. Any such data would likely be found in the original 510(k) for the predicate device, as this device uses the "Same Harmony algorithm."
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "Indications for Use" mention "structural brain injury visible on head CT." This strongly implies that the ground truth for assessing the algorithm's performance (implicitly for the predicate device, as the algorithm is the same) was based on head CT scans.
8. The sample size for the training set
The document does not provide the sample size for the training set for the "Harmony" algorithm. This information would typically be part of the development and validation of the algorithm, likely detailed in the predicate device's 510(k) submission.
9. How the ground truth for the training set was established
The document does not provide this information. Given the ground truth type mentioned (structural brain injury visible on head CT), it would logically have involved interpretation of head CT scans.

§ 882.1450 Brain injury adjunctive interpretive electroencephalograph assessment aid.
(a)
Identification. A brain injury adjunctive interpretive electroencephalograph assessment aid is a prescription device that uses a patient's electroencephalograph (EEG) to provide an interpretation of the structural condition of the patient's brain in the setting of trauma. A brain injury adjunctive interpretive EEG assessment aid is for use as an adjunct to standard clinical practice only as an assessment aid for a medical condition for which there exists other valid methods of diagnosis.(b)
Classification. Class II (special controls). The special controls for this device are:(1) The technical parameters of the device, hardware and software, must be fully characterized and include the following information:
(i) Hardware specifications must be provided. Appropriate verification, validation, and hazard analysis must be performed.
(ii) Software, including any proprietary algorithm(s) used by the device to arrive at its interpretation of the patient's condition, must be described in detail in the software requirements specification (SRS) and software design specification (SDS). Appropriate software verification, validation, and hazard analysis must be performed.
(2) The device parts that contact the patient must be demonstrated to be biocompatible.
(3) The device must be designed and tested for electrical safety, electromagnetic compatibility (EMC), thermal, and mechanical safety.
(4) Clinical performance testing must demonstrate the accuracy, precision-repeatability and reproducibility, of determining the EEG-based interpretation, including any specified equivocal zones (cutoffs).
(5) Clinical performance testing must demonstrate the ability of the device to function as an assessment aid for the medical condition for which the device is indicated. Performance measures must demonstrate device performance characteristics per the intended use in the intended use environment. Performance measurements must include sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) with respect to the study prevalence per the device intended use.
(6) The device design must include safeguards to ensure appropriate clinical interpretation of the device output (
e.g., use in appropriate patient population, or for appropriate clinical decision).(7) The labeling and training information must include:
(i) A warning that the device is not to be used as a stand-alone diagnostic.
(ii) A detailed summary of the clinical performance testing, including any adverse events and complications.
(iii) The intended use population and the intended use environment.
(iv) Any instructions technicians should convey to patients regarding the collection of EEG data.
(v) Information allowing clinicians to gauge clinical risk associated with integrating the EEG interpretive assessment aid into their diagnostic pathway.
(vi) Information allowing clinicians to understand how to integrate the device output into their diagnostic pathway when the device is unable to provide a classification or final result.
