# Intended Use
The Capiox® NX19 Oxygenator with Integrated Arterial Filter and UltraPrime™ Technology is intended to be used to exchange gases between blood and a gaseous environment to satisfy the gas exchange needs of adult and small adult patients during cardiopulmonary bypass surgery.
The integrated arterial filter is intended to filter non-biologic particles and emboli and to facilitate air bubble removal from the blood flowing through the cardiopulmonary bypass circuit. The integrated heat exchanger is used to warm or cool blood and/or perfusion fluid as it flows through the device.
The hardshell reservoir is used to store blood during extra-corporeal circulation from the venous line and the cardiotomy line. The reservoir contains a venous section that is comprised of a filter and defoamer to facilitate air bubble removal. The cardiotomy section of the reservoir contains a filter to remove particulate matter and a defoamer to facilitate air bubble removal. The 4-liter reservoir may be used for Vacuum Assisted Drainage procedures and Post-Operative Chest Drainage Procedures.
The Capiox® NX19 Oxygenator with Integrated Arterial Filter and UltraPrime™ Technology is for use with patients when the required blood flow rate will not exceed 8.0 L/min.
The Capiox® NX19 Oxygenator with Integrated Arterial Filter and UltraPrime™ Technology can be used in procedures lasting up to 6 hours.
#### Principles of Operation and Technology
The Capiox® NX19 Oxygenator utilizes porous fiber technology to facilitate the transfer of gases between a blood-phase environment and a gas-phase environment for the intent of satisfying the gas exchange needs of a patient during cardiopulmonary bypass surgery. A fiber bundle offers the porous membrane surface to sufficiently permit the movement of gases through the walls of the hollow fibers via diffusion.
The Capiox® NX19 Oxygenator device has an integrated heat exchanger that is comprised of Polyethylene Terephthalate tubes arranged in a cylindrical shape. The circulating blood contacts the exterior surface of these tubes. Temperature-controlled water distributed from an external water bath fills the interior of the tubes. The heat exchanger material permits heat transfer to occur across the walls of the heat exchanger tubes to achieve the necessary temperature of the circulating blood.
The Capiox® NX19 Oxygenator device can be operated at flow rates up to 8 liters per minute (1/min) and at a minimum flow rate of 2.0 liters per minute (1/min) or 0.5 liters per minute (1/min) for up to 2 hours.
The integrated arterial filter of the Capiox® NX19 Oxygenator device relies upon mechanical entrapment of particulates and emboli within the filter mesh as a means to remove those particulates from the blood.
{5}------------------------------------------------
Image /page/5/Picture/0 description: The image contains the logo for Terumo. The logo consists of a red, angled line above the word "TERUMO" in green. The font is sans-serif and bolded.
The operation and technology employed by the new NX19 Oxygenator device are consistent with the operation and technology of the predicate FX25 Advance Oxygenator device.
### Design and Materials
The primary differences in the design and materials between the Capiox® NX19 Oxygenator and the predicate device are:
- · Reduction in the diameter of the polypropylene oxygenator fibers vs. the predicate;
- · Higher Molecular weight of Polymethoxyethyl acrylate (PMEA) solution vs. the predicate;
- · Difference in the materials of construct of the heat exchanger plastic vs stainless steel;
- · The NX19 has a lower priming volume vs. the predicate device.
- · The NX19 utilizes pre-heat exchanger vent fiber to facilitate air removal during priming
### Reduction in diameter of the oxygenator fibers:
The Capiox® NX19 Oxygenator utilizes an oxygenator fiber that has a diameter approximately 40% smaller than that of the predicate device. This smaller diameter allows for a larger percentage of the blood in the oxygenator to be in contact with the surface area of the fibers. By increasing this contact, similar gas exchange performance can be achieved with a lower blood volume. The smaller fiber diameter allows the NX19 oxygenator to have a surface of approximately 1.9m² compared to the approximately 2.5m² surface area of the predicate device while still achieving equivalent gas exchange performance.
#### Higher Molecular weight of Polymethoxyethyl acrylate (PMEA) solution:
The X-Coating™ solution utilized to coat the NX19 Oxygenator varies from the solution that is used to coat the predicate device. The NX19 X-Coating™ solution is Polymethoxyethyl acrylate (PMEA). This solution has a molecular weight of 400kDa. The solution for the predicate device is also PMEA solution, but has a lower molecular weight. The predicate X-Coating™ has a molecular weight of 85kDa. This increased molecular weight with the NX19 device allows for increased stability of the coating when applied to the polypropylene fibers of the oxygenator bundle.
#### Difference in the materials of construct of the heat exchanger – plastic vs stainless steel:
The material and the surface area of the heat exchanger in the Capiox® NX19 Oxygenator varies from the predicate device. The heat exchanger tubes in the NX19 Oxygenator are made of Polyethylene Terephthalate (PET) plastic material differs from the stainless steel bellows in the heat exchanger of the predicate device. The surface area of the PET heat exchanger tubes is 0.43m² in the NX19, which is a larger surface area than the 0.2m² in the predicate FX25. This increased surface area ensures that adequate (equivalent) heat exchange is achieved.
# The NX19 has a lower priming volume vs. the predicate device:
The prime volume of the Capiox® NX19 Oxygenator is 185mL, which is lower than the 260mL priming volume of the predicate FX25 device. The reduced prime volume helps reduce the amount of blood that needs to be removed from a patient which, in turn, reduces the need for hemo-dilution.

Both the new NX19 Oxygenator and the predicate FX25 Oxygenator are comprised of the same generic materials, and they both feature common design characteristics. The notable differences in materials and design (as identified above) do not raise any issues of safety or effectiveness. Both devices are deemed to be clinically acceptable.
The NX19 utilizes pre-heat exchanger vent fiber to facilitate air removal during priming To facilitate air removal during priming, the NX19 utilizes pre-HE microporous fiber, oxygenator microporous fiber and a purge port. The FX25 predicate device relies on oxygenator microporous fiber and a purge port for facilitation of air removal during priming (without the presence of pre-HE microporous fiber).
# Performance:
Terumo Cardiovascular Systems has conducted in-vitro performance evaluations for the purpose of demonstrating that the Capiox® NX19 Oxygenator is substantially equivalent to the predicate the Capiox® FX25 Advance Oxygenator. Clinical studies involving patients are not necessary to demonstrate substantial equivalence of the subject device to the predicate device. Substantial equivalence is demonstrated with the following in-vitro performance evaluations:
- Gas Transfer and Pressure Drop Performance ●
- Heat Exchanger Performance o
- Hemolysis Performance •
- . Air Removal Performance
- . Capnography Assessment
- Connection Strength of Ports .
- Filtration Efficiency .
- Mechanical Integrity .
- Luer Port Assessment .
- NX Blood Compatibility .
In addition to the verification testing listed above conducted on the oxygenator, the reservoir testing included in K151791 supports the increased maximum flow rate of the reservoir. The reservoir to be offered with the NX19 oxygenator is the EXACT SAME RESERVOIR that is offered with the FX25 and was cleared in K151791. The verification testing listed below was conducted on the reservoir and presented in K151791. This testing is also presented in Appendix D of this submission:
- . Testing of Air Handling
- Testing of Hemolysis .
- Testing of Venous Defoaming .
- Testing of Pressure Drop .
- Testing of Clotting .
- Testing of Connection Strength .
The Terumo Cardiovascular Systems Corporation Capiox® NX19 Oxygenator exhibits performance features that are deemed "substantially equivalent" to the predicate Capiox® FX25 Advance Oxygenator - K151791.

While the labeling for the NX19 will differ from that of the FX25 with respect to content, the same required elements are present for both devices. Less information will be present on the product label for the NX19 as compared to the FX25. However, the information removed from the product label will be incorporated into a new pouch label. The contents of the box labels will remain the same. Refer to Section 12 - Labeling for more details.
### Substantial Equivalence Statement
The Terumo Cardiovascular Systems Corporation Capiox® NX19 Oxygenator device (with 4liter Reservoir) and the predicate Capiox® FX25 Advance device (with 4-liter Reservoir) are substantially equivalent in intended use, principles of operation and technology, design, materials, performance and labeling. The noted differences between the subject devices and the predicate devices do not raise new issues of safety and effectiveness.
The intended use and product indications of the new NX19 Oxygenator device are consistent with those of the predicate FX25 Advance Oxygenator device.
#### Additional Safety Information
- Sterilization conditions have been validated to provide a Sterility Assurance Level (SAL) of . 10%. Terumo further asserts that the ethylene oxide residues will not exceed the maximum residue limits at the time of product distribution.
- . Terumo maintains biocompatibility studies as recommended in the FDA Guidance Document (6/16/16): Use of International Standard ISO 10993, "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing within a Risk Management Process." [External Communicating Devices, Circulating Blood, Limited Exposure (≤ 24 hours) Contact Duration]. The blood contacting materials were found to be biocompatible.

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.
