The L-Cath Modified Seldinger Technique Accessory Kit is designed for placement and/or exchange of the L-Cath Peripherally Inserted Catheter System in 16 ga. (5Fr.), 18 ga. (4Fr.), 20 ga. (3Fr.), 24 ga. (2.6 Fr.) and the L-Cath Dual Lumen 16 and 18 ga. Utilization of a Modified Seldinger Technique for catheter placement has been demonstrated to be effective for the placement of peripherally inserted central catheters in patients, pediatric and adult, with difficult to access veins.
Device Story
Kit facilitates Modified Seldinger Technique (MST) for placement/exchange of peripherally inserted central catheters (PICCs). Components include over-the-needle insertion catheters, scalpel, measuring tape, sterile drapes, scissors, needle holder, syringe, sheath dilator, and guide wire. Guide wires provided in specialized diameters (.010", .012", .018") to accommodate small-bore neonatal/pediatric catheters. Used by clinicians in clinical settings to gain venous access. Procedure involves needle insertion, guide wire advancement, and sheath/dilator placement to facilitate catheter introduction. Enables successful PICC placement in patients with difficult-to-access veins; reduces risk of complications associated with traditional insertion methods.
Clinical Evidence
No clinical data provided. Substantial equivalence based on bench testing of guide wire outer diameter compatibility with catheter inner diameter and established scientific literature regarding Modified Seldinger Technique complications.
Technological Characteristics
Kit components include stainless steel guide wires, plastic sheath/dilators, and standard surgical accessories. Guide wire diameters: .010", .012", .018". Sheath/dilator sizes: 3, 4, 5 Fr. Introducer needles include echogenic tips. Sterility is required for all components. No software or electronic components.
Indications for Use
Indicated for placement and/or exchange of peripherally inserted central catheters in pediatric and adult patients with difficult venous access.

# SUMMARY:
The contents of the kit are either similar or identical to those devices, with the same intended use, on the market. Luther Medical has smaller neonate/pediatric tubing than the competitors and therefore requires a special guide wire OD to accommodate these catheters. A detail comparison is found on the last page of this summary.
# SUBSTANTIAL EQUIVALENCE:
The guide wire insertion and/or exchange technique has been available to the medical community for over 17 years. The .018” guide wire is too large for the Luther line of catheters specifically used in pediatric and neonatal care.
Testing of the OD of the guide wire through the ID of existing Luther Medical catheters has proven to be accurate and appropriate for this application.
Biocompatibility testing was completed on the guide wire of similar size in another 510(k) for Silicone catheters.
# POTENTIAL COMPLICATIONS:
Extensive studies are available in the scientific literature to address the known complications from an insertion, or exchange, of catheters using the modified Seldinger technique. They include but are not limited to:
| Infection | Discomfort | Arrythmias |
| --- | --- | --- |
| Damage to the Intima of the Vein | Air Emboli | Catheter Emboli |
| Veno Spasm | Difficulty Threading | Difficulty Removing |
| | Catheter | Guide Wire |
| Arterial Placement | Bleeding from Site. | Thrombosis |
# CONCLUSION:
Based on the evidence presented the devices are either essentially similar/or identical materials.
The intended use is the same and therefore the devices are considered substantially equivalent.

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.
