- 3. Intended Use
The Expanse ICE Aspiration System is indicated for the removal of fresh, soft emboli and thrombi from vessels of the peripheral arterial and venous systems.
- 4. Device Description
The Expanse ICE Aspiration System is a peripheral thrombectomy system consisting of several components:
- ICE Aspiration Catheter -
- ICE Aspiration Sheath -
- -Vacuum Fitting
- -High Flow Stopcock Connector
- -Y-Connector with Hemostatic Valve
- Hand Actuator Clip -
The ICE Aspiration System is designed for the minimally invasive removal of thrombus from the peripheral vasculature using aspiration. It is a single use, over-the-wire, catheterbased system with the ability to infuse fluid. The ICE Aspiration System consists of one aspiration catheter, one aspiration sheath, one vacuum fitting, one high flow stopcock connector, one Y-connector with hemostatic valve, and a hand actuator clip.
{4}------------------------------------------------
The ICE Aspiration System is introduced to the primary occlusion. The Aspiration Catheter is advanced through the Aspiration Sheath and targets aspiration directly to the thrombus. The Aspiration Catheter is then retracted back into the Aspiration Sheath. This process of extension and retraction of the Aspiration Catheter is then repeated to fully aspirate the clot. Suction is applied directly to the Aspiration Catheter from an external vacuum source to aspirate thrombus from an occluded vessel (maximum pressure -27.6 in Hg and minimum pressure of -8.0 in Hg).
Sterile saline flows through the Aspiration Sheath and into the Aspiration Catheter when connected proximally. No saline is injected into the patient during aspiration. The Aspiration Catheter and Sheath are visible under fluoroscopy. The hand actuator is an optional, proximal clip attached to the Aspiration Catheter to assist the user.

# 7. Substantial Equivalence Comparison and Conclusion
For substantial equivalence to the ICE Aspiration System a valid, predicate device was identified. The predicate device has the same intended use. Any differences in technological characteristics did not raise new questions related to safety and effectiveness. The predicate device was 510(k) cleared 5 years ago, and has been actively marketed throughout that period.
Expanse Medical has considered the following in evaluation of substantial equivalence:
- Predicate device was cleared using well established methods -
- Predicate device met or exceeded expected safety and performance -
- Predicate device is without unmitigated use related or design related safety issues -
- Predicate device is without an associated design related recall -
{6}------------------------------------------------
A summary of the considerations is provided in substantial equivalence section of this submission. The predicate device used to support this 510(k)-submission used well established methods, had low frequency of reported adverse events and a well-established safety profile through a history of safe use during its on-going marketing duration, and has no known unmitigated use-related or design related safety issues or associated design-related recalls.
The ICE Aspiration System is deemed substantially equivalent to the predicate device in intended use, design, materials, packaging, fundamental scientific technology, manufacturing, important performance specifications, and sterilization. Performance testing and biocompatibility testing demonstrated that the ICE Aspiration System reliably raises no new questions of safety and effectiveness. Finally, the subject device is offered in sizes comparable to the predicate devices intended for use within the peripheral vasculature. Therefore, the ICE Aspiration System is considered substantially equivalent to the predicate device.

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.
