Indications for Use
SURGISEAL Topical Skin Adhesive is intended for topical applications only to hold closed easily approximated skin edges of wounds from surgical incisions, including punctures from minimally invasive surgery, simple, thoroughly cleansed, trauma induced lacerations. SURGISEAL may be used in conjunction with, but not in place of, deep dermal sutures.
Device Story
SURGISEAL is a topical skin adhesive consisting of 2-octyl cyanoacrylate monomer and D&C Violet #2 colorant. It is supplied in a single-use Teardrop applicator featuring a thermoformed blister tray and sponge tip. The device is applied topically by a clinician to hold skin edges together; the adhesive polymerizes in minutes to form a physical barrier against microbial penetration. It is intended for use in surgical and trauma settings. The device acts as a topical closure method; it does not replace deep dermal sutures. The current submission reflects a supplier change for patient-contacting materials.
Clinical Evidence
No clinical data. Bench testing only. Biocompatibility testing (cytotoxicity, acute systemic injection, sensitization, intracutaneous irritation) performed per ISO 10993. Performance bench testing included film thickness, flexibility, linear/surface coverage, set-time, viscosity, and in vitro wound closure strength. Sterilization and shelf-life verified per ISO 11137-2:2006.
Technological Characteristics
Monomeric 2-octyl cyanoacrylate liquid adhesive with D&C Violet #2. Single-use Teardrop applicator (thermoformed blister tray with sponge tip). Sterilized via ethylene oxide and gamma irradiation (ISO 11137-2:2006). Low viscosity formulation for layered application.
Indications for Use
Indicated for topical closure of easily approximated skin edges of surgical incisions (including minimally invasive surgery punctures) and simple, thoroughly cleansed, trauma-induced lacerations. May be used with deep dermal sutures.

#### 4. Device Description
Adhesive containing a monomeric (2-octyl cyanoacrylate) formulation and the colorant D&C Violet #2. It incorporates the Teardrop applicator that consists of a thermoformed blister tray with a heat sealed lid with an attached applicator sponge tip. When SURGISEAL is applied to the skin with the applicator, it polymerizes in minutes.
In vitro studies have shown that SURGISEAL acts as a physical barrier to microbial penetration as long as the adhesive film remains intact. Clinical studies were not conducted to demonstrate microbial barrier properties and a correlation between microbial barrier properties and a reduction in infection have not been established.

#### 5. Intended Use
SURGISEAL is intended for topical applications only to hold closed easily approximated skin edges of wounds from surgical incisions, including punctures from minimally invasive surgery, simple, thoroughly cleansed, trauma induced lacerations.
SURGISEAL may be used in conjunction with, but not in place of, deep dermal sutures.
#### Reason for 510(k) Submission 6.
Device modification to equivalent patient contacting material due to shift of supplier
#### 7. Comparison of Technological Characteristics with Predicate
The technological characteristics of the proposed and predicate devices are similar. SURGISEAL adhesive consists of a monomeric (2-octyl cyanoacrylate) liquid adhesive formulation packaged in a single-use applicator. The device is a low viscosity formulation to allow for varied layered applications of the adhesive to the intended area and allow for either a single consistent intact film thickness, continuous layer or two thin layers of the adhesive to the wound area.
SURGISEAL is used for topical applications only to hold closed, easily approximated skin edges of wounds while maintaining wound approximation.
In vitro studies have shown that SURGISEAL acts as a physical barrier to microbial penetration as long as the adhesive film remains intact. Clinical studies were not conducted to demonstrate microbial barrier properties and a correlation between microbial barrier properties and a reduction in infection have not been established.
#### Performance Testing Summary 8.
# Biocompatibility:
Biocompatibility testing was conducted on the new applicator material per the International Standard ISO-10993, "Biological Evaluation of Medical Devices, Part 1: Evaluation and Testing". The tests included cytotoxicity, acute systemic injection, guinea pig maximization sensitization and intracutaneous irritation test.
With regard to the entire device, biocompatibility testing was previously conducted on the currently marketed device, SURGISEAL Teardrop (K130329).
# Performance Testing:
Bench tests in this submission include Film Thickness determinations for new material component; as well as an assessment of flexibility, linear and surface coverage, set-time and viscosity and in vitro wound closure strength. Shelf life bench testing was also conducted.
# Sterilization and Shelf-Life
SURGISEAL® Topical Skin Adhesive is sterilized by ethylene oxide and gamma irradiation; both in accordance with ISO 11137-2:2006
Stability and shelf life were verified with the same acceptance criteria as the predicate.
#### 9. Conclusion
Based on extensive bench performance testing, the modified device, SURGISEAL Topical Skin Adhesive is substantially equivalent to the predicate.

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.
