The Metacross RX PTA Balloon Dilatation Catheter is intended to dilate stenosis in the iliac, femoral, popliteal, infra-popliteal and renal arteries, and for the treatment of obstructive or synthetic arteriovenous dialysis fistulae. This device is also indicated for stent post-dilatation in the peripheral vasculature.
Device Story
Metacross RX is a rapid exchange PTA balloon dilatation catheter used by physicians in clinical settings to treat peripheral arterial stenosis and arteriovenous dialysis fistulae. The device consists of a distal tube, proximal tube, balloon, guidewire transition tube, radiopaque markers, hub, and strain relief. The physician inserts a guidewire (up to 0.035 inches) through the distal lumen; the balloon is then positioned at the target lesion. An external inflation device connected to the proximal hub inflates the balloon to dilate the vessel or post-dilate a stent. The device facilitates blood flow restoration by mechanically expanding the narrowed vessel lumen. It is compatible with 6F or 7F sheaths/guiding catheters.
Clinical Evidence
Bench testing only. Performance evaluated per FDA guidance for PTCA catheters. Testing included dimensional verification, balloon burst pressure, fatigue, compliance, inflation/deflation time, bond strength, flexibility, kink, torque, radiopacity, and particulate evaluation. Biocompatibility testing conducted per ISO 10993-1, including cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemocompatibility, and genotoxicity. All predetermined acceptance criteria were met.
Technological Characteristics
Rapid exchange PTA balloon catheter. Nominal balloon diameters: 3.0-12.0 mm; working lengths: 20-200 mm; catheter lengths: 900, 1350, 2000 mm. Compatible with 0.035" guidewires and 6F/7F sheaths. Materials are biocompatible per ISO 10993-1. Sterilization method not specified.
Indications for Use
Indicated for patients requiring dilation of stenosis in iliac, femoral, popliteal, infra-popliteal, and renal arteries, or treatment of obstructive lesions in native or synthetic arteriovenous dialysis fistulae, and stent post-dilatation in peripheral vasculature.

#### Predicate Devices:
- EverCross™ .035" OTW PTA Dilatation Catheter or "EverCross" [K082579 (ev3, ● Inc.)]
- Ultraverse® RX PTA Dilatation Catheter or "Ultraverse" [K131199 (Bard Peripheral . Vascular Inc.)]
#### Device Description:
Metacross RX PTA Balloon Dilatation Catheter (Metacross RX) is a rapid exchange balloon dilation catheter, which consists of a distal tube, proximal tube, balloon, guidewire transition tube, radiopaque markers, hub, and strain relief. A balloon is attached to the distal end of the catheter, and it can be inflated and deflated using the inflation device connected to the hub at the proximal end. Metacross RX has a lumen (guidewire transition tube) at the distal end of the catheter through which a guidewire can be inserted, and also an opening along the balloon and distal tube to the guidewire port for the introduction of a guidewire.
The maximum compatible diameter of a guidewire used together with Metacross RX in PTA procedure is 0.035 inches; hence, sheathless guiding catheters and sheaths with a diameter of 6 or 7 Fr have been deemed to be compatible with Metacross RX. The nominal inflated balloon diameters range from 3.0 mm to 12.0 mm with balloon working lengths of 20 mm to 200 mm. Three different catheter working lengths will be provided: 900, 1350 and 2000 mm.
The Metacross RX is provided with the following accessory device:
- . Flushing Needle: provided per one catheter device for the purpose of flushing and filling of the guidewire lumen with heparinized saline before use.
{5}------------------------------------------------
## Indications for Use
The Metacross RX is intended to dilate stenosis in the iliac, femoral, ilio-femoral, popliteal, infra-popliteal and renal arteries, and for the treatment of obstructive lesions of native or synthetic arteriovenous dialysis fistulae. This device is also indicated for stent post-dilatation in the peripheral vasculature.
#### Comparison of Indications for Use to Predicate Devices
The indications for use of the Metacross RX is identical to that of the EverCross. The Metacross RX has the same intended use (percutaneous transluminal angioplasty) and similar indications for use as the Utraverse. Therefore, the subject device, Metacross RX, may be considered substantially equivalent to predicate devices.
#### Comparison of Technological Characteristics to Predicate Devices
#### Technological Comparison to Predicate Devices
The Metacross RX has the following similarities to the predicate devices:
- Same intended use (same as EverCross and Ultraverse) ●
- Same indications for use (same EverCross and similar to Ultraverse)
- . Same target population (same as EverCross and Ultraverse)
- . Same operating principle (same as EverCross and Ultraverse)
- Similar materials (similar to EverCross and Ultraverse)
- Same fundamental scientific technology (same as EverCross and Ultraverse) ●
- . Same sterility assurance level and method of sterilization (same as EverCross and Ultraverse)
## Performance Testing
To demonstrate substantial equivalence of Metacross RX to the predicate devices, the technological characteristics and performance criteria were evaluated the using the bench testing recommendations outlined in the FDA Guidance Document "Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters'' dated September 8, 2010. The following in vitro tests were performed on the subject device:
Dimensional Verification, Balloon Preparation, Deployment and Retraction, Balloon Rated Burst Pressure, Balloon Fatigue (Repeat Balloon Inflations), Balloon Compliance, Balloon Inflation and Deflation Time, Catheter Bond Strength,
{6}------------------------------------------------
Flexibility and Kink Test, Torque Strength, Radiopacity, Particulate Evaluation, Balloon Rated Burst Pressure (in Stent), and Balloon Fatigue (Repeat Balloon Inflations; in Stent), Transportation, and Shelf Life Testing.
The results from these tests demonstrate that the technological characteristics and performance criteria of the Metacross RX are adequate for the intended use of the device and that the device can perform in a manner equivalent to devices currently on the market with the same intended use.
#### Biocompatibility:
To demonstrate the biological safety of the body-contacting materials and substantial equivalence of the Metacross RX to the predicate devices, the following biocompatibility testing was performed in accordance with ISO 10993-1.
Cytotoxicity, Sensitization, Intracutaneous reactivity (irritation), Systemic toxicity (acute), Pyrogenicity, Hemocompatibility (thrombogenicity, hemolysis, and immunology), and Genotoxicity (bacterial gene mutation assay, in vitro mammalian genotoxicity assay, and in vivo cytogenetics assay)
The results from these tests demonstrate that the Metacross RX is biocompatible for its intended use similar to the predicate devices.
#### Conclusions:
The Metacross RX met all the predetermined acceptance criteria of design verification and validation as specified by applicable standards, guidance, test protocols and/or customer inputs. The Metacross RX PTA Balloon Dilatation Catheter is substantially equivalent to legally marketed predicate devices.
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.
