Device Story
Makoto Intravascular Imaging System performs dual-modality imaging using near-infrared spectroscopy (NIRS) and intravascular ultrasound (IVUS) to assess coronary artery vessel composition and structure. System inputs include NIRS light and RF ultrasound signals captured via a specialized catheter during a pullback scan. The system processes these inputs to generate a 'Chemogram' (mapping lipid core-containing plaques) and high-resolution IVUS images (transverse/longitudinal views). Used in clinical settings by physicians during invasive coronary angiography or interventional procedures. Output displayed on console monitors for real-time visualization of plaque burden and vessel pathology. Clinical utility includes identifying patients and plaques at increased risk of major adverse cardiac events, aiding clinical decision-making regarding coronary interventions. Benefits include improved assessment of vulnerable plaques and lipid core burden.
Clinical Evidence
Evidence based on the prospective, multi-center Lipid-Rich Plaque (LRP) clinical study. Study objective: determine relationship between NIRS-detected lipid-rich plaques (LRPs) at non-stenotic sites and prediction of subsequent coronary events at patient and segment levels. Results showed independent, statistically significant association between NIRS-identified coronary lipid cores and occurrence of patient/plaque level major adverse cardiovascular events. No significant differences found based on age, race, ethnicity, or sex.
Indicated for patients undergoing invasive coronary angiography or transluminal coronary interventional procedures requiring near-infrared examination of coronary arteries for lipid-core-containing plaque detection/burden assessment and identification of patients/plaques at increased risk of major adverse cardiac events, or ultrasound examination of coronary intravascular pathology.

Performance Testing (Bench):
#### Biocompatibility
There are no changes to the patient contact materials of the device compared to the predicate (K163345), and therefore no changes to its biocompatibility. The biocompatibility testing reported for the predicate device still applies.
The biocompatibility evaluation of the predicate TVC-C195-42 catheter was conducted for an external communicating device in circulating blood, with a limited contact duration of ≤ 24 hrs. The series of testing was conducted utilizing Good Laboratory Practice (GLP) following ISO 10993 and ASTM standards.
### Sterilization and Shelf Life
There are no changes to the device, its packaging, or the sterilization process requiring sterilization re-qualification. The sterilization testing reported for the predicate device (K163345) still applies.
The sterilization qualification for the predicate was conducted using the TVC-C195-42 catheter and packaging. Results reported met the criteria defined in ISO 11135: 2014.
The shelf life of the TVC-C195-42 catheter was re-evaluated to augment the shelf life from 6 to 18 months compared to the predicate (K163345). The TVC-C195-42 passed all catheter and accessory specifications to support an 18-month shelf life.
# Performance Testing
There are no changes or modifications that significantly affect the safety or effectiveness of the system compared to the predicate (K163345). The proposed device has the same technological, engineering, and performance specifications. Only minor modifications have been made to the device since the market clearance of the predicate.
Verification and validation testing of the predicate was performed on the catheter, console, controller, and software to demonstrate that the system met all design specifications. All modifications were documented, reviewed, and approved per the Quality System Regulation. Where appropriate, modifications were tested according to verification and validation protocols and results recorded and documented per the Quality Management System.
### EMC and Electrical Safety Testing
There are no changes to the device requiring re-evaluation of EMC and Electrical Safety. The EMC and Electrical Safety testing reported for the
{4}------------------------------------------------
| | predicate device (K163345) still applies. Note: EMC testing per IEC 60601-<br>1-2 was repeated after clearance of the predicate device specifically to satisfy<br>Korean regulatory requirements (i.e. testing at 220VAC/60Hz, CB scheme). |
|---------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Performance Testing<br>(Animal): | There are no changes to the device requiring in vivo animal testing.<br>The animal testing reported for the predicate device (K163345) still applies. |
| | The in vivo animal assessment of the predicate device was conducted on<br>swine. There were no safety concerns in the swine coronary artery model<br>after imaging with the TVC-C195-42 catheter. Assessment of the predicate<br>where imaging was performed through an implanted stent to determine<br>apposition and malapposition of the stent met the objectives of the study. |
| Performance Testing<br>(Clinical): | The proposed change is an expansion of the intended use to include an<br>indication stating "The System is intended for the identification of<br>patients and plaques at increased risk of major adverse cardiac events"<br>(see Substantial Equivalence Rationale below). The justification for<br>this label expansion is based on the prospective, multi-center Lipid<br>Rich Plaque (LRP) clinical study. |
| | The overall study objective of the Lipid-Rich Plaque (LRP) Study was<br>to determine in patients undergoing multi-vessel NIRS-IVUS imaging,<br>the relationship between LRPs detected by intracoronary NIRS at non-<br>stenotic sites and the prediction of subsequent coronary events from<br>new culprit lesions at both the patient level (vulnerable patients) and<br>the segment level (vulnerable plaque). |
| | The results satisfied the primary and key secondary endpoints of the<br>LRP Study, demonstrating an independent and statistically significant<br>association between NIRS-identified coronary lipid cores and the<br>occurrence of patient and plaque level major adverse cardiovascular<br>events. There were no statistically significant differences found due to<br>age, race, ethnicity, or sex. |
| Substantial Equivalence<br>Rationale: | There are no proposed changes to the design, scientific principles of<br>operation, principal technological characteristics, or safety of this product.<br>The non-clinical and clinical testing performed on the proposed device<br>indicates that it is safe and effective, and is substantially equivalent to the<br>predicate device. |
| | The proposal is to expand the indications for use of the device as indicated by<br>the underscoring below: |
| | The Makoto Intravascular Imaging System is intended for the near-infrared<br>examination of coronary arteries in patients undergoing invasive coronary<br>angiography. |
| | a.<br>The System is intended for the detection of lipid-core-containing<br>plaques of interest. |
| | b.<br>The System is intended for the assessment of coronary artery lipid core<br>burden. |

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.
