Torpedo Gelatin Foam is indicated for use in embolization of hypervascular tumors.
Device Story
Torpedo Gelatin Foam is a resorbable, hydrophilic porcine gelatin device used for vascular embolization. It is supplied as a compressed, cylindrical dry foam preloaded in a cartridge. During clinical use, the device is rehydrated and injected into a target vessel via an intravascular or micro-catheter. Upon delivery, the device expands to provide a mechanical barrier to blood flow, effectively occluding the vessel. The procedure is typically monitored by a physician using fluoroscopy with contrast enhancement. The device is intended for single use in a clinical setting to treat hypervascular tumors by restricting blood supply. It is provided sterile and includes a blunt stylet for delivery.
Clinical Evidence
No human clinical trials were conducted. Evidence consists of bench testing and an animal study. The animal study (n=15; 7 test, 8 control) in adult female sheep renal arteries evaluated safety and degradation over 4 weeks. Results showed successful embolization with no recovery of normal flow and no significant difference in artery patency between test and predicate devices. Bench testing included macroscopic inspection, swelling, humidity, sterility, pyrogenicity, deliverability, and resorption testing.

Performance
Tests
Once rehydrated, the deformable torpedoes can be injected into the target vessel with an intravascular catheter or a micro-catheter (depending on the size range) to provide a mechanical barrier to blood flow. Contrast enhancement may be used to monitor the embolization procedure using fluoroscopy. The device is intended for single use and is provided sterile.
Torpedo Gelatin Foam is similar in design to the predicate device, EmboCube Embolization Gelatin (K181021), as both of them provide a mechanical barrier to blood flow in the vasculature and are delivered using catheters. The changes to the device are as follows: a) A variant of the gelatin cube device has been added to the range, b) A new packaging has been added, c) A blunt stylet has been included.
The subject device is available in two sizes, as the predicate device. The subject and predicate devices differ in shape. The predicate EmboCube Embolization Gelatin (K181021) has a cubic shape, whether dry or Comparison to hydrated. At the dry state, the subject Torpedo Gelatin Foam is compressed Predicate into a cylindrical shape. In the uncompressed / hydrated state, the subject Torpedo Gelatin Foam is a solid rectangle of the same section as the predicate (2.5 mm or 5.0 mm), only the length differs. Both the subject device and the predicate device, EmboCube Embolization Gelatin, K181021 are made wholly from the identical resorbable porcine qelatin.
> The technological differences between the subject and predicate devices have been evaluated through biocompatibility, bench and animal testing to provide evidence of substantial equivalence of the Torpedo Gelatin Foam to the predicate device, EmboCube Embolization Gelatin (K181021).
> No performance standards have been established under Section 514 of the Food, Drug and Cosmetic Act for these devices. However, vascular embolization devices are subiect to the special controls specified in "Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Vascular and Neurovascular Embolization Devices", issued on December 29, 2004. In addition, the subject device follows the FDA Draft Guidance on Medical Devices Containing Materials Derived from Animal Sources (Except for In Vitro Diagnostic Devices), issued on January 23, 2014.
> A battery of tests performed on Torpedo Gelatin Foam were designed to demonstrate that the device meets critical design specifications as well as clinical performance attributes for its intended use. Where appropriate, the tests were based on the requirements of the following documents:
- FDA Guidance Class II Special Controls Guidance Document: Vascular ● and Neurovascular Embolization Devices (December 29, 2004)

Torepedo Gelatin Foam was evaluated for various performance attributes to demonstrate the substantial equivalence of the device to the predicate. The following is a list of all testing that was successfully completed:
- Macroscopic appearance (visual inspection) ●
- Compressed (dry) torpedo size ●
- Maximum swelling (hydrated size) ●
- Humidity (H₂0 analysis)
- Sterility
- Pvrogenicity (Bacterial endotoxins) ●
- Deliverability with a stylet ●
- Deliverability with catheters and radiopaque contrast agents
- . Flush test carried out on aged and sterilized subject devices
- Resorption .
- Embolic effect .
- . Comparative FTIR analysis for any foreign material transfer
Safety & Performance Tests (continued)
Biocompatibility testing was adopted from the predicate device EmboCube Embolization Gelatin, K181021. The only difference between the subject device and the legally marketed predicate device is that the subject device will be crimped and shaped into a torpedo. FTIR spectroscopy was performed in order to verify that there is no transfer of material from the crimper to the subject device. No further biocompatibility testing was required to qualify the subject device.
An animal study was conducted on seven test (Torpedo Gelatin Foam) and eight control (EmboCube Embolization Gelatin, K181021) adult female sheep in the renal arteries over a period of 4 weeks. The animal study evaluated vascular safety, local tissue effects, and in vivo degradation of the Torpedo Gelatin Foam. Angiography and/or histopathology confirmed that the Torpedo Gelatin Foam provided an embolic effect in renal arteries for at least four weeks. Normal flow of the renal arterial vasculature was never recovered in any animal at any time point. There was no significant difference for artery patency between any articles at any time point. All test animals had a necrotized renal tissue, indicative of successful embolization. The animals were clinically normal throughout the study duration.
The difference between the modified device and the cleared device. Biosphere EmboCube Embolization Gelatin [K181021] has raised no new issues.

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.
