Indications for Use
The Bio-logic Sleepscan product family is intended for use in the recording and analysis of human physiological data necessary for the diagnosis of Sleep-related disorders. It is intended to record and present this data in a form that can improve the speed of diagnosis and assist in potential treatment decisions. Sleepscan Analysis performs calculations and presents recorded data in various ways on the computer screen and in reports. The Analysis features in the Sleepscan product are intended to be performed without patient hookup being necessary, and may even be performed on a different computer system from that which was used for the patient recording. It can be used for patients of all ages, from children to adults, including geriatric patients. The use of the Sleepscan family of products is to be performed under the prescription of a physician or other trained health care professional. The primary feature modification represented in this Special 510(k) is for the use of the Microsoft Windows operating system and its associated user interface functionality.
Device Story
Bio-logic Sleepscan is a polysomnography system for recording/analyzing physiological data to diagnose sleep disorders. This modification migrates the software from MS-DOS to Microsoft Windows, introducing a standard GUI, enhanced reporting, and patient database features. The device processes previously recorded physiological data (e.g., EEG, respiratory signals) to provide graphical displays, epoch-based scaling, and event highlighting. It is used by sleep technologists or physicians in clinical settings to review data, identify respiratory/neurological events, and generate reports. The software does not perform automated diagnosis; it provides computer-assisted highlighting of events, which users can modify, delete, or override. The system facilitates clinical decision-making by presenting data in formats that improve diagnostic speed. Analysis can be performed on a separate computer from the recording hardware, requiring no patient connection during the analysis phase.
Clinical Evidence
No clinical data provided. Safety and effectiveness were established through bench testing, design control procedures (ISO-9001, FDA QSR), and a detailed Hazard/Risk analysis using Fault Tree Analysis (FTA) and EN-1441 standards.
Technological Characteristics
Software-only modification for Windows-based PC environment (recommended Pentium processor). Features include GUI-based data visualization, epoch-based scaling, event highlighting, and database management. No patient-connected hardware is part of this modification. Complies with ISO-9001 and FDA QSR design controls.
Indications for Use
Indicated for recording and analysis of human physiological data for diagnosis of sleep-related disorders in patients of all ages (children, adults, geriatric). Use requires prescription by a physician or trained healthcare professional.
Regulatory Classification
Identification

## SECTION 2: SUMMARY AND CERTIFICATION
# 510(K) SUMMARY
Safety and effectiveness information concerning the Bio-logic Sleepscan product and this Software modification is summarized below.
Because this is not a CLASS III device, the special certification defined for this section is not required.
PREPARED BY: Bio-logic Systems Corp One Bio-logic Plaza Mundelein, IL 60060
TELEPHONE: (847)-949-5200
· CONTACT PERSON: Norman E. Brunner
DATE ON WHICH THE SUMMARY WAS PREPARED: October 30, 1998
NAME OF DEVICE: Bio-logic Sleepscan.
COMMON NAME: Polysomnography System.
CLASSIFICATION NAME: Conditioner, Signal, Physiological (per CFR 882, 1845),
PREDICATE DEVICE: Bio-logic Sleepscan, reference 510(k) #K894155.
### DESCRIPTION OF THE DEVICE:
The Bio-logic Sleepscan family of products is intended to be used for the recording and analysis of human physiological data for the purpose of diagnosis and treatment of Sleep-related disorders. The predicate vice referenced above was the first such system marketed by Bio-logic. Other related devices comprising the Sleepscan family include:
- 1 . 510(k) #K930790 - Addition of Oximeter to Sleepscan Product.
- 510(k) #K964132 Modification to Bio-logic Sleepscan product with Built-in Oximeter, 2.
- 3. 510(k) #K971501 - Sleepscan Airflow Pressure Transducer.
{1}------------------------------------------------
The predicate device performs both Sleep recording and analysis functions, providing up to 40 channels of simultaneous data recording from a variety of sensors and transducers, and a number of specialized analysis functions including event highlighting and Sleep stage identification. Related Device #1 above is a recording hardware modification to Bio-logic's standard 32-channel EEG recording system, incorporating a built-in Oximeter module and DC channels specifically designed for Sleep recordings. Related Device #2 above is another recording hardware modification, this one based on the Bio-logic "Ceegraph Traveler" (510(k) #K954954) device. Also incorporating a built-in oximeter, this is a smaller battery-operated device offering fewer recording channels at a lower price. Related Device #3 above is a very sensitive transducer for the recording of airflow associated with breathing, based on the measurement of air pressure variations instead of the more indirect method using temperature measurements.
Throughout the history of the Sleepscan product, from the introduction of the present, all Sleepscan software has been developed and based on the Microsoft MS-DOS Operating System. This new Special 510(k) is for the Device Modification of Sleepscan software, the primary new feature being the use of the Microsoft Windows Operating System. As such, although most of the standard Sleepscan functions are very similar to those used in the DOS version, much of the User Interface and presentation of graphical data is now performed using Windows-standard Graphical User Interface (GUI) methods. This 510(k) does not cover the recording functions of the Sleepscan family, which are defined in the predicate device and Related Devices #1 and #2 above. Data recording may be performed using any of the Bio-logic approved-for-market Sleepscan and Ceegraph recording devices with the associated recording software. Any recordings made for the diagnosis and treatment of Sleep disorders can be analyzed with either the existing DOS-based software or the new Windows-based software. This latter software package is the subject of this 510(k).
Most of the finctional features of the Bio-logic Sleepscan for Windows software package are similar to those of the predicate device. These include:
- Graphical presentation of the "raw data" as recorded by one of the recording devices. .
- Epoch-based data scaling to simulate paper recordings. ﻬ
- Variable time scaling of data (simulating a variety of "paper speeds") and variable epoch sizes for detailed � or summary viewing.
- Rapid report generation based on operator review and interaction with the data presented by the Analysis � software.
- Several summary graphs allow for the display of the complete night's Sleep recording on one screen, � allowing the user to quickly identify periods of the study requiring closer scrutiny.
- Graphical Overlay with Zoom-In allows the user to quickly look at "interesting" periods of a night's Sleep � recording at the raw data level.
- User-defined montages and comments. �
- Screen presentations can be customized to display several different kinds of data in separate windows at � the same time.
- Data analysis is performed on specific channels of raw data for the identification of possible respiratory or � neurological events.
- + Color-coded events highlight areas of the data for further review by the technologist or physician.
- Computer-assisted highlighting of data events can be easily modified or deleted by the user, and new � events not highlighted by the program can be added at the user's discretion.
{2}------------------------------------------------
New features in the Windows-based software include:
- ◆ Standard Windows GUI functionality.
- · Extensive On-line Help.
- · More extensive and user-configurable reporting features.
- · Patient database information features.
- · Enhanced sleep stage scoring features.
INTENDED USE: The Bio-logic Sleepscan product family is intended for use in the recording and analysis of human physiological data necessary for the diagnosis of Sleep-related disorders. It is intended to record and present this data in a form that can improve the speed of diagnosis and assist in potential treatment decisions. Sleepscan Analysis performs calculations and presents recorded data in various ways on the computer screen and in reports. The Analysis features in the Sleepscan product are intended to be performed without patient hookup being necessary, and may even be performed on a different computer system from that which was used for the patient recording.
It can be used for patients of all ages, from children to adults, including geriatric patients. The use of the Sleepscan family of products is to be performed under the prescription of a physician or other trained health care professional.
The primary feature modification represented in this Special 510(k) is for the use of the Microsoft Windows operating system and its associated user interface functionality.
# SAFETY AND EFFECTIVENESS SUMMARY
To establish the safety and effectiveness of the Sleepscan for Windows software, the system was designed in accordance with the Bio-logic internal Product Development procedures which meet ISO-9001 and FDA QSR Design Control specifications. A detailed Hazard/Risk analysis was performed using the Fault Tree analysis (FTA) approach, and a detailed Risk Assessment was written in accordance with EN-1441, the International Standard for Hazard/Risk analysis.
Because this modification to Sleepscan consists of only software and there is no patient connection required. there are no hardware-related methods by which the patient can be harmed or injured through the use of this device. In addition, although extensive signal analysis and computer-assistance is provided to the user in the form of event identification and data highlighting, the program does not make any final decisions that result in any automatic forms of diagnosis or treatment. All program "recommendations" are subject to review by the Sleep Technologist or Physician, and may be modified, overridden or deleted as determined by a qualified user. The program provides extensive functionality to allow the qualified user to review all raw data collected, create and highlight new and/or custom events, and otherwise the data analysis to suit his or her requirements.

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.
