Indications for Use
The membrane oxygenator Quadrox-i Adult is intended for the use in extracorporeal circulation during cardiopulmonary bypass in cardiac surgery. Within the specified flow rate range, the device oxygenates the blood, eliminates carbon dioxide and regulates blood temperature. The Quadrox-i Adult (HMO 71000) version with integrated arterial filter also filters out air bubbles and particles larger than 40 um. The device's utilization period is limited to six hours. Responsibility for deciding whether to use an oxygenator rests solely with the attending physician.
Device Story
The QUADROX-i and QUADROX-iD are membrane oxygenators used in extracorporeal circulation during cardiac surgery. The device oxygenates blood, removes carbon dioxide, and regulates blood temperature. Models with integrated arterial filters remove air bubbles and particles (≥33-40 µm). The modification adds a reusable stainless steel holding clamp, applied by a perfusionist, to prevent accidental disconnection of inlet/outlet connectors. The device is used in the OR by perfusionists; output is the treated blood returned to the patient. The clamp serves as a protective safeguard; it does not alter the fundamental oxygenation/filtration function. Benefits include maintained circuit integrity during bypass.
Clinical Evidence
No clinical data provided; bench testing only. Verification testing included holding force, pull-off force, vibration testing (up to 3G and roller pump simulation), leakage testing with reduction adapters, and usability testing in three hospitals.
Technological Characteristics
Membrane oxygenator with optional integrated arterial filter. Materials include stainless steel for the added holding clamp. Operates via extracorporeal circulation for gas exchange and temperature regulation. Flow rates vary by model (0.2-5 L/min). Utilization limited to 6 hours. No software or electronic components.
Indications for Use
Indicated for patients undergoing cardiac surgery requiring extracorporeal circulation during cardiopulmonary bypass. Includes adult, small adult, and pediatric populations. Utilization limited to 6 hours.

Premarket Notification Special 510(k) - Change due to recall/corrective action Modified QUADROX-i, QUADROX-iD
### Technological Characteristics:
The modified devices as mentioned above are identical to the originally cleared devices, with the exception that an added reusable stainless steel holding clamp is applied by the perfusionist prior to use as an interim protective safeguard in the unlikely event that the inlet and/or outlet connector would become loose. Besides this difference, the proposed devices are the same in design, intended use, method of operation, components, packaging, and fundamental scientific technology as the predicate devices.
### Non-clinical Tests:
The modified devices were subjected to design verification tests which are based on the risk assessment. The tests are designed to show that the clamp can be mounted on the Oxygenator, so that the clamp will stay in place during its use, and in the unlikely event that the bonding of the connectors to the housing would fail the connector would not detach from the housing.
The tests simulate relevant mechanical conditions in the use of the Oxygenators. The following mechanical tests were performed:
{6}------------------------------------------------
Premarket Notification Special 510(k) - Change due to recall/corrective action Modified QUADROX-i, QUADROX-iD
- Holding Forces Force applied to the connectors to hold the clamp in ﮯ place
- Pull off Forces Force to remove the holding clamp from the housing : perpendicular to the clamping force.
- . Vibration Test with Shaker - Simulate impact forces up to 3G and confirm the secure attachment of the clamp under repeated impact.
- Vibration Test with Roller Pumps Relevant for QUADROX-i / iD products ﺑﺎ to simulate the influence of repeated motions of the tubing.
- . Leakage Test with Reduction Adapter - Relevant only to the Quadrox-i pediatric/neonatal products used in combination with 1/4" x 3/16" reduction adapters 09844-s. The test confirmed that the clamp can be used with the pediatric/neonatal reduction adapters.
- Usability test This test was performed in three hospitals and evaluated i as to whether the clamp could be mounted using the Instruction for Use.
The holding clamp as an external component of the cleared QUADROX-i does not affect the performance specifications related to the intended use.
Based on the tests listed above, the modified devices are safe and effective according to the intended use and are substantially equivalent to the originally cleared device.
#### Clinical Tests:
Clinical results are not required for this submission to support substantial equivalence.
#### Conclusion:
Based on the risk analysis, MAQUET Cardiopulmonary AG has conducted the appropriate design verification activities and believes that the modified devices are substantially equivalent to the cleared MAQUET predicate 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.
