#### DEVICE DESCRIPTION:
The X-Series System is indicated for acquiring, transmitting, displaying and storing physiological data in patients. It can be used with ambulatory patients in the home, health care facility, or clinical research environment. The X-Series system requires operation by a trained technician.
The X-Series System.is comprised the X10 and X24 Headsets and accessories, Synapse Cream, X-Series Basic Software and BT receiving unit. The X-Series Basic Software is also compatible with the Models X4-E, and X4-M (K130013) when used in wireless mode.
The X-Series System combines hardware, firmware and software to acquire physiological signals. It acquires physiological data through a battery powered headset worn by the patient and provides a flexible platform for applying sensors using synapse cream and acquiring signals from multiple locations on the head or body, transmitting and recording the signals and providing visual indications to ensure high quality data are obtained.
Model X24 provides for acquisition of twenty channels of electroencephalography (EEG) and four optional channels connected to two sensors via a dual-lead connector. Model X10 provides for acquisition of nine channels of electroencephalography (EEG) and an optional channel connected to two sensors via a dual-lead connector. Both models measure movement and position measured via a 3-D accelerometer. The device is designed so it can be affixed by a technician and displays the signals via a wireless connection during acquisition. The X-Series Basic software monitors signal quality to ensure that the sensors are properly applied and that high quality signals are being acquired.
The X-Series Basic software provides a means to: a) initiate a study and track patient information, b) acquire and wirelessly transmit signals from the device, c) visually inspect the signal quality.
The acquired signals are saved in a universal data format (European Data Format Plus, EDF+) that is intended to be analyzed by a Physician using FDA cleared third party software, i.e. Persyst Software (K011397).

#### DETERMINATION OF SUBSTANTIAL EQUIVALENCE:
#### SUMMARY OF NON-CLINICAL TESTS:
Support for the substantial equivalence of the X-Series System was provided as a result of risk management and testing which included electrical and biological safety, performance and software tests. Testing has provided reasonable assurance of safety and effectiveness for the intended use and supports a determination of substantial equivalence.
Bench tests were conducted using an oscilloscope and signal generator to compare performance of the X-Series to the predicate device. These comparison tests confirm the EEG
{8}------------------------------------------------
and optional dual-lead (for ECG) analog signals between the X-Series and predicate devices were equivalent. The X-Series and X4 were placed in a jig that held the devices in eight unique angles to confirm that the measures obtained from the 3D actigraphs were equivalent. While the X-Series System is not a cardiac monitor as defined in the scope of ANSI/AAMI EC 13, the standard was referenced and requirements and test methods applicable to the electrocardiogram acquired and displayed by X-Series was applied. These tests demonstrated the equivalence of the X-Series system to the predicate device for EEG, ECG and actigraph performance.
The cleaning and disinfection procedures of the X-Series acquisition device have been validated by testing in accordance with AAMI TIR 12-94 Designing, Testing, and Labeling Reusable Medical Devices for Reprocessing in Health Care Facilities: A Guide for Manufacturers and AAMI TIR 30: 2003 A Compendium of Processes, Materials, Test Methods, and Acceptance Criteria for Cleaning Reusable Medical Devices. Acceptance criteria established by Advanced Brain Monitoring and the TIR are ≥ log 3.0 reduction in bioburden after cleaning according to the instructions for use. All tests passed and demonstrate that the cleaning methods are appropriate for ensuring the X-Series acquisition device is clean between uses.
Biocompatibility was assessed following FDA Guidance "Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing' (Replaces #G87-1 #8294) (blue book memo)". Per Table 1 of this guidance, the X-Series System is a Surface device with limited contact (Category A, less than 24 hours contact). As such, cytotoxicity, sensitization, and irritation or intracutaneous reactivity tests were selected. Test methods were in compliance with the corresponding standard from the ISO 10993 series for Biological Evaluation of Medical Devices. Test articles were comprised of all patient contacting components of the X-Series System, including the X-Series Strip with disposable foam and synapse cream, X-Series Strap and X-Series enclosure. Results of biocompatibility testing are summarized in table 2 and demonstrate that materials of the device in contact with the patient are biocompatible.

#### SUMMARY OF CLINICAL TESTS:
To provide additional support for use in ages 6 and older, a subset of data from a research study was analyzed to establish use of the X-10 and X-24 headsets to acquire EEG in this patient population. Data from seven children ages 6-8 were compared to data from seven adults. The subjects were set-up by a technician with the X-Series strip appropriate based on their head measurements as described in the labeling. Technicians were able to quickly set-up subjects and resolve any high impedance issues as displayed by the X-Series Software. None of the subjects complained of discomfort or agitation in wearing the strips and the sensors remained in contact with the scalp for the duration of testing. 100% of all EEG sessions contained appropriate EEG recordings that could be further examined in third party software, and when data acquired from children are compared to an equivalent adult population, the data quality were equivalent.
#### CONCLUSION:
Based on the results of the non-clinical and clinical tests performed, Advanced Brain Monitoring considers the X-Series System to be as safe, as effective, and substantially equivalent to the predicate devices.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
