Indications for Use
The PRONTO extraction catheter is indicated for the removal of fresh, soft emboli and thrombi from vessels in the coronary and peripheral vasculature. The SKYWAY support catheter is intended to be used in conjunction with steerable guidewires in order to access discreet regions of the arterial and or coronary vasculature. It may be used to facilitate placement and exchange of guidewires and other interventional devices. The SKYWAY OTW also may be used to subselectively infuse/deliver therapeutic agents. The TWIN-PASS dual access catheter is intended to be used in conjunction with steerable guidewires in order to access discrete regions of the coronary and peripheral arterial vasculature, to facilitate placement and exchange of guidewires and other interventional devices, for use during two guidewire procedures and to subselectively infuse/deliver diagnostic or therapeutic agents.
Device Story
Catheter family includes extraction (Pronto V3/LP) and support/access (Skyway RX/OTW, Twin-Pass) devices. Extraction catheters use dual-lumen design; larger lumen allows thrombus aspiration via syringe/stopcock; smaller lumen accommodates guidewires. Support/access catheters provide guidewire support; facilitate guidewire exchange; Twin-Pass allows dual-guidewire procedures; Skyway OTW/Twin-Pass allow subselective infusion. All devices are hydrophilically coated. Used in interventional procedures by physicians to navigate coronary/peripheral vasculature. Pronto catheters include 70um filter basket for thrombus analysis. Stiffening mandrels/stylets included for delivery support. Clinical benefit: improved vessel access, thrombus removal, and therapeutic delivery.
Clinical Evidence
Bench testing only. Verification testing and biomaterial assessments performed to qualify hydrophilic coating modifications.
Technological Characteristics
Dual-lumen (Pronto/Twin-Pass) or single-lumen (Skyway) catheters; hydrophilically coated; compatible with 0.014" guidewires; 6F guide catheter compatible; includes accessories (syringes, stopcocks, 70um filter basket, stiffening mandrels/stylets).
Indications for Use
Indicated for removal of fresh, soft emboli and thrombi from coronary and peripheral vessels (Pronto V3/LP); access to coronary/arterial vasculature, guidewire placement/exchange, and subselective infusion of therapeutic/diagnostic agents (Skyway/Twin-Pass).
Regulatory Classification

#### General Information
## Device Description
The Pronto V3 extraction catheter is a dual lumen, hydrophilically coated, rapid exchange catheter with related accessories. The smaller wire lumen of the catheter is able to accommodate guidewires that are ≤ 0.014"/0.36mm in diameter. The larger extraction lumen allows for the removal of thrombus by use of the included syringe through the extension line and stopcock. The catheter has a rounded distal tip with a protected, sloped opening of the extraction lumen to facilitate advancement of the catheter into the blood vessel and maximize extraction of thrombus through the extraction lumen. The proximal end of the catheter has a standard luer adapter that attaches to the included extension line, stopcock and syringes. The catheter has a working length of 140cm and is compatible with standard 6F guide catheters. A 70um filter basket is included for assistance in filtering the blood removed during the procedure for laboratory analysis of any thrombosis.
The Pronto LP extraction catheter is a dual lumen, hydrophilically coated rapid exchange catheter with related accessories. The smaller wire lumen of the catheter is able to accommodate guidewires that are <0.014"/0.36mm in diameter. The larger extraction lumen comes pre-loaded with a stylet that resists kinking during delivery but is removed to allow for the removal of

{7}------------------------------------------------
thrombus by aspiration. The catheter has a rounded distal tip with a protected, sloped opening of the extraction lumen to facilitate advancement of the catheter into the blood vessel and maximize extraction of thrombus the extraction lumen. The proximal end of the catheter has a Yadapter hub containing a self-sealing stylet port, as well as a side-port for the attachment of the included extension line. The catheter has a working length of 137cm and is compatible with standard 6F guide catheters. A 70um filter basket is included for assistance in filtering the blood removed during the procedure for laboratory analysis of any thrombosis.
The Skyway OTW (over-the-wire) and Skyway RX (rapid exchange) support catheters are single lumen, hydrophilically coated catheters designed for use in the arterial vasculature. The catheters provide support for 0.014"/0.36mm guidewires during interventional procedures, and allow for the exchange of one distally located guidewire for another one while maintaining access to distal vasculature. The Skyway RX has a rapid exchange port that allows for the insertion of the catheter over a short guidewire; a stiffening mandrel provides support and pushability during catheter insertion.
The Twin-Pass dual access catheter is a hydrophilically coated, dual lumen catheter designed for use in the arterial vasculature. The catheter provides support for 0.014"/0.36mm guidewires during interventional procedures, and the dual lumen design allows for the delivery of a second guidewire into distal vasculature while leaving the initial guidewire in place. A stiffening mandrel provides support and pushability during catheter insertion.
#### Intended Use / Indications
The PRONTO extraction catheter is indicated for the removal of fresh, soft emboli and thrombi from vessels in the coronary and peripheral vasculature.
The SKYWAY support catheter is intended to be used in conjunction with steerable guidewires in order to access discreet regions of the arterial and or coronary vasculature. It may be used to facilitate placement and exchange of guidewires and other interventional devices. The SKY WAY OTW also may be used to subselectively infuse/deliver therapeutic agents.
The TWIN-PASS dual access catheter is intended to be used in conjunction with steerable guidewires in order to access discrete regions of the coronary and peripheral arterial vasculature, to facilitate placement and exchange of guidewires and other interventional devices, for use during two guidewire procedures and to subselectively infuse/deliver diagnostic or therapeutic agents.
### Substantial Equivalence and Summary of Studies
Pronto, Skyway and Twin-Pass catheters are substantially equivalent in intended use / indications and design to their predicate devices. Hydrophilic coating design differences have been qualified through biomaterial assessments and verification testing, the results of which did not raise any new safety or performance questions.

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.
