#### Indications for Use V.
The Terumo® Advanced Perfusion System 1 is indicated for use for up to six hours in the extracorporeal circulation of blood for arterial perfusion, and cardiopulmonary bypass procedures, when used by a qualified medical professional who is experienced in the operation of this or similar equipment.
The centrifugal pump is indicated for use in cardiopulmonary bypass procedures only.
#### VI. Comparison of Technological Characteristics
The indications for use for the subject and predicate devices are identical.
The subject and predicate devices are identical with respect to mechanism of action and all components except the Central Control Monitor (CCM). The CCM hardware (e.g., computer, PCB, storage, and supporting subassemblies) and associated software is being revised to address subassembly component obsolescence.
Key hardware modifications include replacing the CCM computer and touch screen with a flatpanel computer system. The flat-panel PC is electromechanically simpler than the current computer and touch screen as it has fewer components and fewer internal hardware interconnects. The subject CCM will support USB flash drives for external storage in place of PCMCIA flash memory cards. The CCM mounting arm was modified to accommodate the lighter CCM weight.
The following software modifications are being introduced:
- 0 CCM Software updates for supporting the new CCM and USB LAN I/F hardware. ONX version upgrade to 6.5 and to provide support for USB flash drive storage.
- 0 Software for USB LAN I/F for CAN-USB communications between the base and CCM, and real-time clock time keeping.
- Software for Power Manager Board to remove diagnostic battery current measurement ● test made unnecessary by new flat-panel PC
- Other minor software modifications: ●
- Update system shut down counter to count down from 10 to 1 instead of up from o 1 to 10
- Correct On, Off and Mute buttons state display in Air subtab under specific o circumstances
- Update handling of system time change to prevent the display of a negative value o while a perfusion timer is running
{6}------------------------------------------------
- Update pumps icon rotation speed graphics display for better consistency with o actual pump speed
- Handle any onscreen keyboard display in case of fatal system shut down. o
- Remove unnecessary error event logging in System event log o
- Update dropdown list of temperature probe location labels O
These changes do not raise different questions of safety or effectiveness as there is no impact to the intended use, indication for use, or operating principle.
#### VII. Performance Data
The following performance data were provided in support of the substantial equivalence determination:
- o Software validation
Software system testing was conducted though testing performed following the Terumo Quality system. Software system testing relies on system level testing of the CCMD, LAN I/F , and Power Manager Pod as well as other Non-SST verification methods such as code reviews, integration testing, or other verification methods.
Requirements are verified by software system testing and/or non-SST verification. These instances include some boundary tests and generation of messages that are unable to be tested through software system testing alone due to equipment constraints. The overall functionality of the requirement is verified through software system testing however other Non-SST test methods are required to fully verify the requirement.
At the conclusion of Software validation, all requirements identified as software system requirements were successfully met.
- Hardware verification 0
Hardware verification was conducted using testing, inspection, demonstration, and analysis techniques in accordance with TCVS procedures. The following activities were completed to show all design verification requirements were successfully met:
- Internal testing: Internal testing was conducted under approved protocols to o verify requirements were met for:
- . mounting arm performance,
- mounting arm environmental conditions,
- CCMD gloved hand response, and
- = power consumption.
- o External testing: External testing was performed to Standards:
- . Electrical safety testing per IEC 60601-1
- . Electromagnetic Compatibility testing per IEC 60601-1-2
{7}------------------------------------------------
- Shipping and vibration testing per ISTA-3A and MIL-STD-810G, Method 514.6 (10Hz-100Hz)
- Inspection: Inspections were conducted to verify requirements related to physical o characteristics such as hardware characteristics and documentation.
- Demonstration: System level demonstration was used to verify action-oriented o features to test basic operations and deterministic behaviors of the design.
- Analysis: Analyses were conducted to augment testing and other verification o activities. This includes mounting arm and CCMD performance, CCMD environmental conditions, and power consumption.
- Reliability ●
Verification of all requirements identified as device reliability requirements was conducted through testing, analysis, and similarity. These activities confirmed all applicable materials requiring cleaning and label adhesion successfully passed established acceptance criteria and that the CCMD meets all reliability targets and 12 year life.
- Validation ●
Hardware validation was executed through testing under an approved protocol. Usability testers consisting of external perfusionists executed the use cases. This validation testing successfully completed verification of the requirements, user needs and risk mitigations within the project scope.
# VIII. Conclusion
The information provided above supports that the Terumo® Advanced Perfusion System 1 is equivalent to the predicate device with respect to intended use and technological characteristics. Verification and validation testing supports that the hardware and software differences do not raise any new questions of safety and effectiveness. Therefore, it is concluded that the Terumo® Advanced Perfusion System 1 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.
