Section 3 Proposed Labeling
Draft proposed labeling for the "Cutalon" Nonabsorbable Polyamide Surgical Suture includes the actual device labeling and the package insert. Sample draft labeling for the device is provided in Appendix A.
{2}------------------------------------------------
### Section 4 Device Description
"Cutalon" is a wet-packed, extruded, nylon monofilament suture. The base polymer material is Nylon 6. (As required in CFR 878.5020) The nylon suture material is foilpackaged "wet" in a solution containing isopropyl alcohol, water and other components (see below description of formulation).
The packaging fluid contains: Isopropyl Alcohol 73.65% 1.2-Propylene Glycol 15.00% Water 8.25% Glycerin 2.30% Lactic Acid 0.45% Diethanolamine 0.20% Sodium Nitrite 0.10% Ammonia 0.05%
The purpose of the "wet" packaging is to provide a nylon suture that is supple (easier to twist and tie) straight from the package due to the water absorption into the nylon.
Genzyme "Cutalon" Surgical Suture are available in USP sizes 6-0 through 0 (metric sizes 0.7 through 3.5). Genzyme Cutalon Sutures meet all requirements established by the United States Pharmacopeia (USP) for nonabsorbable sutures except for diameter.
The "Cutalon" Suture is identical in design, materials (Nylon 6), manufacturing process and intended use to the Nylon Suture already marketed by Genzyme Surgical Products. This "Cutalon" Suture is simply a change in the packaging.
Genzyme's Nylon Suture has been on the market since December 1976. In Appendix D, please see a copy of NDA 85-060 FDA letter from December 1976 and also see a copy of the FDA's 510(k) letter dated July 26, 1994 which confirms that Genzyme has followed the instructions for "Suture Labeling Guidance" dated October 9, 1992.
{3}------------------------------------------------
## Design, Materials, Process, Packaging
The "Cutalon" Suture is designed to maintain sterility of the product until the time of use. Each individual suture/needle assembly is wrapped around a plastic winder and the combination is placed inside an open-ended pouch. The suture assemblies in their pouches are then loaded into the packaging machine. This machine forms a polyethylene "blister" and seals a medical grade paper lid stock onto it after it is filled with packaging fluid and product. The sealed blister is placed into a purchased film/Tyvek pouch and sealed on a bar sealer. (The bar sealers were validated for outer pouch sealing for the "wet" products and a packaging machine was validated for wet packed inner blister packaging. The pouch is designated to allow sterilization with the pouch and maintain a sterile environment until the pouch is opened. The Cutalon Nylon suture is foil-packaged "wet" in a solution containing isopropyl alcohol, water and other components. The purpose once again of the "wet" packaging is to provide a Nylon suture that is supple (easier to twist and tie) straight from the package due to the water absorption into the nylon.
The "wet" pouches are placed into solid bleached sulfite board boxes, with instructions for use. Polyamide suture packages are opened by peeling open the pouch. The loaded carrier is then aseptically opened in the sterile field. There is a clear film overwrap applied to the shelf box as a dust cover. Outer corrugate shipping cartons of various sizes are used to ship the suture boxes.

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.
