Indications for Use
The Satellite is intended to acquire EEG data from patients that are stationary or ambulatory, regardless of whether they are inside or outside a medical-care facility.
Device Story
Satellite is a portable, battery-powered digital EEG recorder worn by patients in a hip belt. It records EEG signals during ambulatory or home use, storing data on a removable PCMCIA-type hard disk drive. After recording, the drive is removed and connected to a standard personal computer for review, analysis, and report generation by a medical practitioner. The PC also manages system utilities, such as programming user-selectable parameters and measuring electrode impedance. The device is intended to complement existing EEG systems by enabling ambulatory monitoring. It does not perform automated diagnosis; clinical judgment is required to interpret the output. The device benefits patients by allowing EEG recording outside of clinical settings, facilitating the diagnosis of conditions like epilepsy while maintaining normal patient activity.
Clinical Evidence
No formal clinical trial was conducted for validation. Nonclinical bench testing used actual human EEG recordings, including seizures, spikes, and artifacts, to verify performance. Clinical testing was limited to user-feedback assessments under actual-use conditions to solicit comments; no adverse effects or complications were reported. The device performed as expected.
Technological Characteristics
Portable, battery-powered digital EEG recorder. Uses removable PCMCIA-type hard disk drive for data storage. Features user-adjustable parameters, electrode impedance measurement, and battery-powered operation with external charger. Designed for ambulatory use. Technological characteristics are virtually identical to predicate devices regarding bandwidth, channel count, and resolution.
Indications for Use
Indicated for patients requiring ambulatory or home EEG monitoring to assist medical practitioners in diagnosing EEG-related conditions, such as epilepsy.
Regulatory Classification
Identification

(4) Description of the device, including an explanation of how the device functions, the scientific concepts, and the significant performance characteristics such as device design, material used, and physical properties.
The Satellite is a portable, battery-powered, digital electroencephalographic (EEG) data recorder that is designed to be carried in a hip belt worn by the patient. The intended use of this device is to record the patient's EBG while the patient is ambulatory or at home. Recorded EEG data is stored in a removable hard disk drive, which the medical practitioner can then remove from the data recorder and connect to a standard personal computer. The personal computer is then used to review and analyze the EEG data, generate reports, and provide longer-term storage for the EEG data. The personal computer also performs various system utility functions on the data recorder, such as programming the user-selectable parameters, and measuring the electrical impedance of the EEG electrode connections. A battery pack and charger also accompany the data recorder. These items are designed so the battery pack cannot be recharged while it is powering the data recorder, so the data recorder (which may be attached to the patient) cannot be connected to the AC-powered charger. The device is intended to complement Nicolet's existing line of EEG systems, including the Voyageur digital EEG system (K921927B) and BMSI long-term EEG monitoring system (K891405A). Neither of these devices currently provides the capability for ambulatory or athome EEG data recording, however, both will record and playback EEG data that is similar to the data recorded by the Satellite.
(5) Statement of the intended use, including a description of the patient populations, and diseases or conditions, that the device is intended to diagnose, treat, prevent, cure, or mitigate. If different
{2}------------------------------------------------
from the predicate device, an explanation of why the differences are not critical to the intended use when the device is used as labeled.
The Satellite is intended to record EEG data while a patient is ambulatory or at home, and is intended to involve competent human intervention before any impact on human health occurs (i.e., clinical judgment and experience must be used to check and interpret the system's output). The device does not obscure information or data that is available to the user; it does not eliminate the use of complementary information, such as patient history information, laboratory results, and other tests; it does not change the intended use of the predicate device or similar devices; it does not create new or different indications for use for the predicate device or similar devices: and, except for recording data to assist a medical practitioner in diagnosing EEG-related conditions (such as epilepsy), it does not diagnose, treat, prevent, cure, or mitigate any illness, disease or condition. Moreover, because the device primarily records EEG data for review at a later date, and therefore provides ample opportunity for the clinician to cross-check results and perform additional tests, any failure of the device to perform as intended would be extremely unlikely to significantly alter or delay the treatment of any patient, or contribute to any injury or adverse health effect.
(6) Comparison between the technological characteristics of the new and predicate devices, such as design, material, chemical composition, energy source, etc.
The technological characteristics of the new and predicate devices are virtually identical. Each device relies on a portable battery-powered data recorder to store up to 24 hours of a patient's EEG data in a digital format onto a standard (PCMCIA-type) removable hard-disk drive. Each device is small, lightweight, and intended for ambulatory use. Each device has a similar bandwidth and channel count, a similar time- and amplitude-resolution, and a similar set of user-adjustable parameters. Each device has similar performance specifications, and is designed to comply with substantially the same voluntary performance standards.
### (b) INFORMATION REQUIRED IF EQUIVALENCE IS BASED ON PERFORMANCE DATA
(1) Brief discussion of nonclinical tests.
Nonclinical tests consisted of using the device to record EEG test data derived from actual human EEG recordings, and included examples of actual seizures, spikes, seizure-like artifacts, and non-seizure waveforms. Test results are summarized below in paragraph (b)(3).
(2) Brief discussion of clinical tests including, if applicable, a description of the subjects, a discussion of safety or effectiveness data obtained, a discussion of any adverse effects or complications, and any other relevant information.
Clinical tests were deemed unnecessary for purposes of validating the device's ability to perform its intended use, because non-clinical tests appeared clearly superior to any clinical tests that could be developed. Nevertheless, clinical tests were performed to solicit comments
{3}------------------------------------------------
from actual users and to assess the performance of the device under actual-use conditions. There were no adverse effects or complications affecting patients, and the device performed substantially as expected.
(3) Conclusions drawn from nonclinical and clinical tests that demonstrate that device is as safe and effective, and performs as well as or better than the legally marketed device identified in (a)(3).
Even though the predicate devices identified in (a)(3) were not available for direct comparison testing, results of testing the Satellite showed that it was substantially equivalent, in terms of safety and effectiveness, to the specifications published for the predicate devices. In addition, the nonclinical and clinical test results for the Satellite showed that it was substantially equivalent, in terms of safety and effectiveness, to much larger Nicolet EEG products, including the BMSI long-term EEG monitoring system (K891405A).

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.
