## Device Description
The Affinity Pixie Oxygenators are microporous, hollow-fiber, gas-exchange devices available with Cortiva BioActive Surface or Balance Biosurface bonded blood contacting surface. The oxygenator is used in an extracorporeal perfusion circuit to oxygenate and remove carbon dioxide from the blood and to cool and warm the blood during routine cardiopulmonary bypass procedures up to six (6) hours in duration. The oxygenator has a low prime volume which is appropriate for use in neonate, infant and small pediatric patients.
The Affinity Pixie Cardiotomy/Venous Reservoir (CVR) with Cortiva BioActive Surface or Balance Biosurface is a single use device designed to collect venous and cardiotomy suctioned blood during routine cardiopulmonary procedures up to six (6) hours in duration. Additionally, the Affinity Pixie CVR may be used during vacuum assisted venous drainage (VAVD) procedures and collect autologous blood from the chest and to aseptically return the blood to the patient for blood volume replacement during open heart surgery. The CVR allows a lower operating volume which is appropriate for use in neonate, infant and small pediatric patients.
The oxygenator can be connected to a heater/cooler device, recirculation circuit, cardioplegia circuit, and the main blood path. These connections are made with tubing connected to barbed or
{8}------------------------------------------------
luer ports. The oxygenator is under constant fluid pressure. There is pressure exerted on the blood-side of the device from the blood pump and patient, the water-side of the device due to the flow of the heater-cooler for water, and the gas-side of the device due to the flow of gases through the device. The three compartments (blood-side, water-side and gas-side) must not leak into one another for the oxygenator to function properly.
The water-side of the oxygenator is connected to a heater/cooler device to enable temperature control of the blood. To prevent microbial growth within the heater/cooler, some manufacturers specify the addition of disinfectants to the heater/cooler water. During operation, the water path of the polyethylene terephthalate (PET) heat exchanger is exposed to these disinfectants.
The purpose of this 510(k) Notification is to notify the FDA of a change to allow for the use of hydrogen peroxide (330 ppm) in the water path of the oxygenator. There are no actual changes to the oxygenators.
#### Indications for Use
There is no change to the intended use of the devices within the scope of the proposed change in this 510(k) Notification. The current Indications for Use statement for each device model are noted below:

The Affinity Pixie cardiotomy/ venous reservoir is intended to be used in an extracorporeal perfusion circuit to collect venous and cardiotomy suctioned blood during routine cardiopulmonary procedures up to 6 hours in duration. The CVR is also intended for use during vacuum-assisted venous drainage (VAVD) procedures.
#### Comparison to Predicate Devices
When compared to the predicate devices, the Affinity Pixie Oxygenators are substantially equivalent. The oxygenators within scope of this 510(k) Notification have the following similarities:
- Same intended use
- Same operating principle ●
- Same fundamental technological characteristics ●
{10}------------------------------------------------
- Same design, dimensions and performance
- Same device materials
- Same packaging materials and design ●
- Same sterilization requirements
### Summary of Performance Data
While these devices are subject to special controls, most of the special control requirements are not applicable for this proposed change. During use, the water path of the heat exchanger is the only part of the oxygenator that is exposed to a disinfectant. Because of this, it is not necessary to repeat all recommended testing by the special control guidance documents. It is however necessary to conduct testing to verify the chemical disinfectant has no adverse effects on the oxygenator water path. The following testing and analysis was performed:
- Heat Exchanger Product Material Compatibility with Hydrogen Peroxide .
- Structural Integrity Testing (pressure integrity, burst and port break tests) ●
- Toxicological Risk Assessment for Hydrogen Peroxide
- Heat Exchanger Permeability Testing .
#### Conclusion
In conclusion, the information provided within this submission demonstrates the Affinity Pixie Oxygenators with/without Cardiotomy/Venous Reservoir and Balance Biosurface or Cortiva BioActive Surface are substantially equivalent to the marketed 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.
