#### II. DEVICE DESCRIPTION:
The EPI Mini ECG Portable Health Monitoring System ("EPI Mini") is a portable recording device which is designed to be used in combination with an individual's smartphone to create a portable health monitoring system. Not only does the EPI Mini record and store a user's physiological data but when paired with smartphone technology is capable of wirelessly transmitting such data to a remote server for review, monitoring and interpretation by a learned intermediary, and subsequent forwarding to the user's physician when necessary.
The device can function as an Rx product when prescribed by and used under the supervision of a physician for the purpose of monitoring a patient's ECG data. It is not a diagnostic device.
The EPI Mini is a portable single-channel device composed of 3 metallic electrode sensors strategically located on 3 sides of the device. The EPI Mini measures electrical differences between two points when in direct contact with the user's skin surface and is capable of recording new Electrocardiograms or ECGs every 30 seconds.
Holding the sides of the device (the metallic sensors) with their left and right hands, the user presses the "Enter" button to begin ECG recording. It takes approximately 30-45 seconds to measure an ECG.
A recorded ECG can then be sent to the user's smartphone (i.e., a mobile or cellular telephone) using patented bluetooth technology that relies on a proprietary EPI mHealth Application or "EPI mHealth App" which can be downloaded from the user's respective App store. The App allows a user to wirelessly transmit the ECG data to a remote server for monitoring by a learned intermediary, processing, storage and when necessary, forwarding on to the user's physician for

K121628 P 3/4
review and evaluation. From the remote server and monitoring center, the data can be delivered to a physician by mobile phone, fax, email or internet. The mHealth App also allows storage of ECGs on the user's smart phone.
The mHealth App also allows for the personal storage of a user's own physiological data such as blood pressure, blood glucose levels and cholesterol. Such stored data can be updated and retrieved for later use and also displayed in a line graph format for trend analysis. Additionally, the mHealth App permits a user to view, resend and/or delete saved data as needed.
The EPI Mini is composed of several individual components including (1) the EPI Mini portable ECG recorder, (2) a USB data cable, (3) the mHealth application which can be purchased and downloaded from the user's respective application store, and (4) a 500mAh battery.
#### III. INDICATIONS FOR USE
The EPI Mini Portable ECG Recorder ("EPI Mini") is intended for use with a patient's smartphone to record, store and wirelessly transmit physiological data to a remote server. It is indicated for individuals who are at risk for cardiac disease, experience transient symptoms . suggesting possible cardiac arrhythmia or have existing heart conditions.
The device can function as an Rx product when prescribed by and used under the supervision of a physician for the purpose of monitoring a patient's ECG data. It is not a diagnostic device.
The EPI Mini is intended for use by adults who suffer from cardio-vascular disease, are considered high risk for possible cardiovascular events or are concerned about their heart function and rhythm.
#### IV. SUMMARY OF TECHNICAL CHARACTERISTICS OF THE DEVICE COMPARED TO THE PREDICATE DEVICES
The EPI Mini is substantially equivalent to the FDA-cleared REKA E100 ECG Event Recorder (Cardiac Rhythm Monitor) (K111438) ("REKA E100") and the Signalife Fidelity 200 Cardiac Event Recorder (K071228) ("Signalife").
All three of the devices are intended to record. store. transmit and receive physiological data via the user's own smartphone.

The device is designed to measure and record personal health data, including but not limited to, a user's own ECGs.
The EPI Mini and the cited predicate devices are all intended for use by individuals at risk for cardiac disease and those who experience transient symptoms suggesting possible cardiac arrhythmia. They are also indicated for individuals who require monitoring for the detection of non-lethal cardiac arrhythmias.
{3}------------------------------------------------
K121628 P 4/4
Similar to the REKA E100, the EPI Mini is a 1 lead ECG event recorder that is capable of recording an ECG every 30 seconds. Both devices are capable of transferring data to a computer or mobile phone. The EPI Mini, like the REKA E100, also comes with its own mobile application software allowing the device to communicate with a user's smartphone. Finally, neither device is designed to diagnose, or signal or trigger an alarm.
As for the identified Signalife predicate device, the EPI Mini is similar in that it is also a battery operated ECG event recorder that can record an ECG in less than one minute. Following recording, both devices allow for ECGs to be transtelephonically transmitted to a cardiac monitoring station for analysis and diagnosis by a learned intermediary. Both devices are capable of storing a user's recorded ECGs for later review.
The minor design differences amongst the three devices do not affect the substantial equivalence of the devices to one another. A Substantial Equivalence Comparison Table is attached for a side-by-side comparison of the EPI Mini and the three cited predicated 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.
