## DEVICE DESCRIPTION [807.92(a)(4)]
The Peerbridge Cor™ System is a family of products comprised of two models, the Peerbridge Cor™ XT ("Cor XT") and the Peerbridge Cor™ Event ("Cor Event"). The system is an ambulatory wearable ECG monitoring system designed to record and provide patient's electrocardiogram (ECG) data to the clinician.
The Peerbridge System consists of five components: (1) Wearable ECG Sensor with Bluetooth technology, (2) Adhesive Electrode (3) dedicated Handheld Transmitter Device, (4) Data Upload Fixture and Software that allow ECG data to be uploaded from the Wearable ECG Sensor to a PC and then to the Backend, and (5) Cloud-based Backend Data Management Module. The Wearable ECG sensor attaches to the patient's chest and records the patient's ECG continuously. This device can collect two (2) channels of ECG data continuously for up to seven (7) days. In addition, patients can report symptomatic events by pressing the Event Button on the Wearable ECG Sensor or by using the mobile application on the Handheld Transmitter when a symptom is experienced. The device generates ECG reports to be displayed on the clinician's interface.
The Peerbridge System Cor XT and Cor Event have identical functionalities and components while differing in post-data acquisition clinical workflow. These configurations are presented in Table 1 with their respective tests. Through the two configurations, the system supports three tests based on medical necessity determined by the prescribing clinician.
| Peerbridge Cor XT | Peerbridge Cor Event |
|----------------------------------------------|------------------------------------------------------|
| Test 1: 24 hours of Holter monitoring | Test 1: 24 hours of Holter monitoring |
| Test 2: Up to 7 days of Holter<br>Monitoring | Test 3: Patient Activated Event with<br>Surveillance |
### Table 1- Peerbridge System Family Configurations
To initiate a test, the clinician uses the Peerbridge Portal to enter the patient's profile and select the appropriate test (Test 1, Test 2, or Test 3).
## INDICATIONS FOR USE [807.92(a)(5)]
The Peerbridge Cor™ System family of products is intended to capture and transmit symptomatic events and continuous external electrocardiogram (ECG) information for 24 hours and up to 7 days (long term monitoring). The Peerbridge Cor™ System contains a continuous external electrocardiogram (ECG) recorder with a patient-activated events button. It is indicated for use on adult patients 18 years or older who may be asymptomatic or who may suffer from transient symptoms such as palpitations, shortness of breath, dizziness, light-headedness, presyncope, fatigue, or anxiety. The reported ECG metrics supports 2-channel ECG analysis on a beat-by-beat basis, heart rate measurement and rhythm analysis by FDA cleared algorithms. The report generated does not contain diagnostic interpretation; the report is provided for review by intended users to render a diagnosis based on their clinical judgment and experience.
{5}------------------------------------------------
### COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICES [807.92(a)(6)]
The Peerbridge System and the SkyRunner predicate device both capture, record, transmit, and analyze symptomatic events and continuous ECG recordings over an extended period in adult patients who may be asymptomatic or who may suffer from transient symptoms such as palpitations, shortness of breath, dizziness, light-headedness, pre-syncope, fatigue, or anxiety. The Peerbridge System and the SkyRunner provide a report of the analyzed ECG data for the clinician to interpret. The reports for both systems are generated by FDA-cleared algorithms. Similar to the SkyRunner, the ECG data report is displayed in the clinician interface. Overall, the Peerbridge System is similar to the predicate device in terms of technological and safety characteristics and differences in technological characteristics have been analyzed and tested to ensure that there are no different questions of safety or effectiveness.
### SUBSTANTIAL EQUIVALENCE
The Peerbridge System is substantially equivalent to the SkyRunner. The two devices have the same intended use and similar technological characteristics. Differences in the technological characteristics between the devices do not raise different questions of safety or effectiveness. Thus, the Peerbridge System is substantially equivalent to the predicate device.

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.
