Indications for Use
The AngioVac Cannula is indicated for use as a venous drainage cannula and for removal of fresh, soft thrombi or emboli during extracorporeal bypass for up to 6 hours.
Device Story
AngioVac Cannula is a venovenous cannula featuring a balloon-actuated, expandable, funnel-shaped distal tip. Advanced percutaneously or via surgical cut-down through a 26 Fr sheath over a guidewire. Connected to an extracorporeal circuit comprising an AngioVac Circuit, centrifugal pump, and bubble trap. A separate reinfusion cannula is placed for venous return. Upon pump activation, suction removes blood and debris from the cannula tip; blood circulates through a filter and returns to the patient. Used in clinical settings for thrombus/embolus extraction from vessels like the iliofemoral vein, IVC, SVC, and Right Atrium. Minimizes blood loss via recirculation. Benefits include effective removal of soft thrombi/emboli during extracorporeal bypass.

## D. Device Description
The AngioVac device is a venovenous cannula with a balloon-actuated, expandable, funnel shaped distal tip that can be advanced through a 26 Fr sheath over a guidewire into the venous system percutaneously or via a surgical cut-down. During use, the cannula is connected to an extracorporeal circuit including an AngioVac Circuit, a commercially available centrifugal pump and bubble trap. A commercially available reinfusion cannula is placed for venous return (typically within internal jugular or one of the common femoral veins) and connected to the extracorporeal circuit. When the pump is started, suction is created, removing blood and debris from around the tip of the AngioVac
{5}------------------------------------------------
Cannula, circulating the blood through the filter, returning the blood to the patient via the venous return cannula. A benefit of the AngioVac Cannula is that it allows for removal of thrombus/embolic material, while minimizing blood loss via recirculation of blood through a standard extracorporeal (venovenous) bypass circuit. Target vessels for thrombus/embolus extraction include, but are not limited to, the iliofemoral vein, Inferior Vena Cava (IVC), Superior Vena Cava (SVC) and Right Atrium (RA). The device is provided in a straight and an angled (20°) configuration.
### E. Indication For Use
The AngioVac Cannula is indicated for use as a venous drainage cannula and for removal of fresh, soft thrombi or emboli during extracorporeal bypass for up to 6 hours.
## F. Technology Characteristics
Within this current premarket notification, AngioDynamics is proposing to implement design modifications to the subject cannula to expand the product offering and/or to improve ease of use. Modifications include: Addition of an angled tip (20 degrees) cannula configuration; inclusion of radiopaque markers on the panels of the distal tip funnel to aid visualization; inclusion of stopcock on proximal end of the balloon inflation line; increased wall thickness of the balloon inflation line between cannula shaft and stopcock; modifications to the inner balloon; addition of a female quick disconnect to allow for an easier connection to the AngioVac Circuit; addition of hydrophilic coating on outside of obturator to facilitate obturator placement/removal from the cannula; and enhanced packaging configuration for improved presentation of product to sterile field (i.e., product packaged in tray instead of pouch).
With the exception of the hydrophilic coating on the obturator and inclusion of the radiopaque markers on the cannula distal tip, the proposed AngioVac Cannula is manufactured of the same materials used in the manufacture of the currently marketed predicate AngioVac Cannula. Additionally, there have been no changes to the shaft size or profile.
The proposed device has similar indications for use, materials, design, components and technological characteristics as the currently marketed AngioVac Cannula (K133445).
{6}------------------------------------------------
### G. Performance Data
Comprehensive bench testing (integrity, functional performance and particulate evaluation) was performed to support substantial equivalence of the AngioVac Cannula. The AngioVac Cannula met all specified design and performance requirements. Additionally, the AngioVac Cannula has fulfilled the biocompatibility testing requirements identified in ISO 10993: Biological evaluation of medical devices Part 1: Evaluation and testing in the risk management process for an externally communicating device with circulating blood of a limited duration. Specifically the following tests were performed with acceptable results: cytotoxicity, sensitization, irritation, systemic toxicity and hemocompatibility.
Animal testing was also performed in accordance with 21 CFR Part 58. The results of the animal testing performed with the modified AngioVac Cannula have demonstrated the following:
- . No evidence of hemodynamic compromise during use of the modified AngioVac Cannula
- No evidence of vessel injury noted on the final angiograms attributable to the . placement and use of the AngioVac Cannula
- No abnormal gross or histological findings were noted in test vessel segments ● attributable to the placement and use of the AngioVac Cannula.
- No significant vascular response in these experimental conditions associated ● with the application of the modified AngioVac Cannula.
### H. Clinical Testing
Not applicable
### I. Conclusion
Based on responses to questions posed in the FDA's Decision Making Flow Chart, the proposed device is substantially equivalent to the predicate device.
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.
