#### K192864
UNI*FUSE™ Infusion System with Cooper Wire Infusion Catheter 21CFR870.1210 Catheter, Continuous Flush Class 2 KRA Cardiovascular Devices
### Purpose
The purpose of this Special 510(k) is to introduce into commercial distribution a slight expansion of the UNIFUSE Infusion Catheter with Cooper Wire devices recently cleared under predicate 510(k) K192864; specifically, to expand the range of available configurations to include those with 10cm and 15cm "infusion segment lengths". This would be an addition to those 2cm and 5cm "infusion segment length" configurations recently cleared via that predicate 510(k), and in sum would expand the current range of "infusion segment length" options as follows:
- Current range of "Infusion Segment Length" options (via predicate K192864): 2cm, 5cm ●
- Proposed range of "Infusion Segment length" options: 2cm, 5cm, 10cm, 15cm
{5}------------------------------------------------
Aside from this "infusion segment length" difference, there are no other modifications being proposed to the device – catheter overall length, diameter, device materials, Indications for Use, device labeling, and all other device attributes remain identical to those cleared via predicate 510(k) K192864.
# Device Description
The proposed UNIFUSE Infusion System with Cooper Wire devices are single-lumen, nylon catheters with longitudinal slits located at 90° intervals around the distal end of the catheter for fluid delivery. An occluding ball wire (or occlusion guidewire) provides end-hole occlusion during fluid delivery. The catheters are available in 4F and 5F diameters and overall lengths of 90cm and 135cm. Additionally, they are available in multiple infusion segment lengths, including 2cm, 5cm, 10cm, and 15cm lengths – the latter two of which are the subject of this proposal. It is also worth noting that the overall length of each catheter remains the same no matter the length of the infusion segment. The active infusion area can be identified under imaging by means of radiopague markers on the catheter shaft at the distal and proximal ends of the infusion segment. As shown in Table 1 below, all of these characteristics are substantially equivalent to those of the predicate devices.
The proposed UNIFUSE Infusion System with Cooper Wire devices are intended for administration of fluids such as thrombolytics and contrast media into vessels that are impacted by thrombus, including the peripheral and pulmonary artery vasculature. Given the minimal physical differences of the vessels for which the device is intended to access (e.g. diameter, structure, tortuousness), the operating principle mechanism of action, and intended use is the same independent of anatomical location, use in the pulmonary artery is equivalent to other areas of the vasculature that the device is currently indicated for.
## Indications for Use/Intended Use
The UNIFUSE Infusion System with Cooper Wire is intended for the administration of fluids, including thrombolytic agents and contrast media, into the peripheral and pulmonary artery vasculature.
### Comparison of Similarities and Differences in Technological Characteristics and Performance
The proposed UNIFUSE Infusion System with Cooper Wire and the predicate UNIFUSE Infusion System with Cooper Wire (K192864) are identical to one another (and therefore substantially equivalent) in all terms, not limited to design, materials of manufacture, specifications, Indications for Use, and sizes and/or configurations, as depicted in the comparison via Table 1 below. The sole difference is the proposed 10cm and 15cm "infusion segment length" attribute.

Furthermore, the proposed UNFUSE Infusion System with Cooper Wire devices and predicate UNIFUSE Infusion System with Cooper Wire devices are incorporative of the identical operating principle, mechanism of action, intended use, and Indications for Use as one another (in addition to exhibiting identical overall design, materials of manufacture, sizes/configurations, and all other device attributes). Based upon the conclusions above, all previous biocompatibility, sterilization, shelf-life, and general performance testing supporting the predicate UNIFUSE Infusion System with Cooper Wire devices remains supportive of the proposed UNIFUSE Infusion System with Cooper Wire devices – the sole difference is that AngioDynamics, Inc. executed the same "human factors" testing conducted in support of K192864, in order to evaluate the 10cm and 15cm "infusion segment length" configurations proposed herein.
### Comparison of Performance Data
As touched on above, the proposed UNIFUSE Infusion System with Cooper Wire devices and predicate UNIFUSE Infusion System with Cooper Wire devices are the same device as one another, and as a result the performance testing that AngioDynamics, Inc. has on file for the predicate devices remains supportive of the proposed devices (the sole difference being the "human factors" testing executed on the proposed 10cm and 15cm "infusion segment length" configurations). Please refer to Table 2, below:
{7}------------------------------------------------
| Table 2: Summary of Performance Testing |
|-------------------------------------------------------------------------|
| Proposed and Predicate UNIFUSE Infusion System with Cooper Wire |
| -Slit Pattern Radiopacity |
| -Catheter Degradation |
| -Catheter Pressure |
| -Catheter-to-Occlusion Wire Configuration (Slow Infusion Compatibility) |
| -Catheter/Accessory Compatibility |
| -Catheter/Fluid Compatibility |
| -Catheter Hub-to-Shaft Joint Kink Resistance |

| -Distal Spring Tip-to-Mandrel Connection |
| -Occlusion Wire Withdrawal |
| -Human Factors Testing |
Human Factors Testing: In support of predicate 510(k) K192864, AngioDynamics, Inc. had conducted a human factors study on the UNIFUSE Infusion System with Cooper Wire configurations proposed therein. Specifically, Angiodynamics, Inc. solicited the participation of multiple practicing physicians experienced in the use and placement of infusion catheters to evaluate use of the devices on a simulated-use vascular model. The goal of the testing was to demonstrate the following:
- The devices are able to be navigated-to and used-within the pulmonary artery vasculature;
- . The infusion segments are able to be clearly imaged under imaging (and thus confirmed to reside completely within the pulmonary artery vasculature);
- The Directions for Use include adequately detailed instructions in order to enable users to accurately and reliably place and use the device(s) within the pulmonary artery vasculature.
This same human factors testing was therefore executed on the 10cm and 15cm "infusion segment length" configurations proposed herein. Additionally, the predicate 2cm and 5cm "infusion segment length" configurations were also tested again as a means of directly comparing the proposed and predicate devices side-by-side and further demonstrating that these proposed configurations are acceptable for the pulmonary artery vasculature intended usage. To that end, it is confirmed that the results did show that the proposed 10cm "infusion segment length" configurations are able to navigate the vasculature, be placed and used within the pulmonary artery, and have their location confirmed under imaging (e.g. fluoroscopy) – the same conclusions arrived at for those cleared via predicate 510(k) K192864. These determinations justify the expansion of the cleared configurations to include these 10cm and 15cm "infusion segment length" options.
### 510(k) Summary Conclusions
In conclusion, assessment of the similarities and differences of the proposed and predicate UNIFUSE Infusion System with Cooper Wire devices are identical and thus substantially equivalent to one another; specifically:
- . The proposed and predicate device have the identical ProCode, Regulation Number, Regulation Name, and Regulatory Class as one another;
- The proposed and predicate device have identical Indications for Use and/or Intended Uses;
{8}------------------------------------------------
- The proposed and predicate devices incorporate the identical operating principle, mechanism of ● action, and are intended for the same patient populations; and,
- . The proposed and predicate employ an identical overall design, materials of manufacture, performance testing, sizes, and configurations, aside from the 10cm and 15cm "infusion segment length" options being proposed herein.
Additionally, results of human factors testing on the proposed UNIFUSE Infusion System with Cooper Wire provide further evidence that the devices are able to be used in the pulmonary artery vasculature, as are the predicate devices. Lastly, the Special 510(k) was determined to be the most appropriate pathway for premarket notification based upon having met the criteria for such a submission type via FDA's Guidance Document, "The Special 510(k) Program – Guidance for Industry and Food and Drug Administration Staff" (September 13, 2019).
The sum of these evaluations and determinations lead AngioDynamics, Inc. to conclude that substantial equivalence has been demonstrated, and that the existing data, additional testing, and clinical evaluation determinations have confirmed that there are no new questions of safety or effectiveness.
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.
