# Device Description
The Reveal® LINQ™ Insertable Cardiac Monitor (ICM) Model LNQ11 is designed to record the occurrence of arrhythmias in a patient. Arrhythmia may be classified as atrial tachyarrhythmia/atrial fibrillation (AT/AF), bradyarrhythmia, pause, or (fast) ventricular tachyarrhythmia. The Reveal LINQ ICM provides storage of ECG and Marker Channel during patient-activated and automatically-detected (auto-activated) events. Auto-activation may help to detect abnormal heart rhythms in patients who may not activate/trigger the ICM. The Reveal LINQ Model LNQ11 is a small, leadless implantable device that is typically implanted under the skin, in the chest. Two electrodes on the body of the implantable device continuously monitor the patient's subcutaneous ECG.
# Medtronic Reveal LINQ (Model LNQ11) ICM
The Reveal LINO ICM is a small, leadless implantable device that is implanted under the skin, in the chest. The implantable device uses two electrodes on its surface to monitor the patient's subcutaneous ECG continuously. The implantable device memory can store up to 27 min of ECG recordings from automatically detected arrhythmias and up to 30 min of ECG recordings from patient-activated episodes. The system provides 3 options for segmenting the patientactivated episode storage: up to four 7.5 min recordings, up to three 10 min recordings, or up to two 15 min recordings. Arrhythmia detection parameters are set to pending automatically, based on patient information entered on the programmer during pre-insertion implantable device setup: the patient's Date of Birth and the clinician's Reason for Monitoring the patient. Arrhythmia detection parameters can also be programmed manually by the clinician. The following table describes the Reveal LINO ICM Model LNO11 when used with the alternative LINO Programmer Application and patient connector as compared to the Reveal LINQ ICM Model LNQ11 when used with the existing programmer software and hardware.

The Reveal LINO ICM Model LNO11 was initially cleared via a 510(k) application K132649 on February 14, 2014. This submission introduces an alternative programming option (referred to as the LINQ Programmer system) for the Reveal LINQ ICM. The LINQ Programmer system is comprised of LINO Programmer Application Model MSW001 installed on a clinician's off-theshelf non-medical mobile device and patient connector Model 24965 (also referred to as a telemetry head) used in conjunction with the CareLink Network. The Reveal LINO ICM continues to have the same intended use when used with the LINQ Programmer system. The LINQ Programmer system provides the essential capabilities for programming, interrogating and managing the Reveal LINQ ICM in a clinical or hospital environment.
The LINQ Programmer system has no impact on the physical characteristics, materials, mechanical, electrical, hardware, components, firmware, operation, performance, and telemetry protocol of the Reveal LINQ ICM. There are no differences in the performance, features, materials, hardware, firmware, intended use or programmer-to- implantable device interface between the Reveal LINO ICM used with the LINO Programmer system versus the existing programmer software and hardware. The LINQ Programmer system is capable of interrogating and programming the Reveal LINO ICM like the existing programmer software and hardware.
# Indications for Use
There are no changes to the cleared indications for use for the Reveal LINQ ICM Model LNQ11 when used with the LINQ Programmer Application and patient connector as compared to the Reveal LINQ ICM Model LNQ11 indications when used with existing programmer software and hardware.
The indication statement is as follows:
The Reveal LINQ ICM is an insertable automatically-activated and patient-activated monitoring system that records subcutaneous ECG and is indicated in the following cases:
- patients with clinical syndromes or situations at increased risk of cardiac arrhythmias o
{6}------------------------------------------------
- patients who experience transient symptoms such as dizziness, palpitation, syncope, . and chest pain that may suggest a cardiac arrhythmia
The device has not been tested specifically for pediatric use.
# Technological Characteristics
The Reveal LINQ ICM consists of three major subassemblies which include the hermetically enclosed battery, hermetically enclosed electronics module, and molded header assembly. The battery is a custom D-shaped cell based on LiCFx chemistry and supports a 12-month shelf life and 3-year usable capacity. The Electronics Module contains the hybrid comprised of a printed circuit board with surface mount components on one side and an over molded stack on the other side which contains analog, digital and memory IC's along with capacitor arrays. The molded Header Assembly contains a Titanium Nitride coated sensing electrode, an embedded miniature RF antenna, suture hole, and a mounting bracket.
The Reveal LINO ICM will continue to use the same technology. It is designed to automatically record the occurrence of an arrhythmia in a patient, continuously senses the patient's subcutaneous ECG, and analyzes the timing of ventricular events to detect possible episodes of arrhythmia. The Reveal LINQ ICM has a small form factor, and uses Titanium, Parylene, Urethane, and Titanium Nitride coating on the sensing electrodes as body contacting materials.
The use of the LINO Programmer system to support the Reveal LINO ICM does not alter the existing technology of the Reveal LINQ ICM. Additionally, from the system perspective, the LINQ Programmer Application still communicates via an RF head (the patient connector) which in turn communicates with the Reveal LINQ ICM to program diagnostic settings and to extract data from the implantable device for viewing on either the LINO Programmer Application or the Medtronic CareLink Network. The patient connector utilizes the same telemetry protocol (Telemetry B) to communicate with the Reveal LINQ ICM; however, it utilizes Bluetooth technology to communicate with the mobile device, and has rechargeable battery-powered operation. The LINO Programmer Application utilizes existing infrastructure of the clinician's mobile device to run the programming application facilitating, portability and mobility, direct connectivity with CareLink via cellular and Wi-Fi, Bluetooth connectivity to communicate with the patient connector, software updates via publicly accessible channels (i.e. Google Play Store), and a user interface with workflows, streaming ECG waveform and marker display.
# Summary of Testing
Testing was performed to demonstrate equivalency of the Reveal LINQ Model LNQ11 Insertable Cardiac Monitor with LINQ Programmer Application and patient connector to the Reveal LINQ ICM with existing programmer software and hardware. The Reveal LINQ ICM with LINQ Programmer Application and patient connector were subjected to the same use scenarios during testing as the Reveal LINO ICM with existing programmer software and hardware, thus supporting substantial equivalency. Testing included:
### Reveal LINO (Model LNO11) Testing
System verification and system validation were completed with the Reveal LINQ Model LNQ11 Insertable Cardiac Monitor.
{7}------------------------------------------------
### LINO Programmer Application (Model MSW001) Testing
Performance verification as well as software verification, system verification and system validation were completed for the LINQ Programmer Application.
#### Patient Connector (Model 24965) Testing
Electromagnetic compatibility (EMC), RF compliance, electrical safety, mechanical, packaging, biocompatibility and performance verification testing were completed for the patient connector. Additionally, firmware verification, system verification and system validation were completed with the patient connector. The patient connector is provided non-sterile.
The results of the testing indicate that the Reveal LINQ Insertable Cardiac Monitor Model LNQ11 with the LINQ Programmer Application (Model MSW001) and patient connector (Model 24965) perform as intended, and are safe for their intended use.
The FDA recognized standards that the Reveal LINQ Insertable Cardiac Monitor Model LNQ11, LINQ Programmer Application (Model MSW001), and patient connector (Model 24965) complies are identified in the following tables.

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.
