SIS BLU is intended for use in gastrointestinal endoscopic procedures for submucosal lift of polyps, adenomas, early stage cancers or other gastrointestinal mucosal lesions, prior to excision with a snare or other endoscopic device.
Device Story
SIS BLU is a sterile, single-use submucosal injection system; consists of AMP BLU particles (absorbable modified polymer + 0.06% Brilliant blue dye) and a spiral plunger syringe. Used in GI endoscopic procedures; operated by clinicians. User mixes AMP BLU particles with saline in the provided syringe; attaches to a standard endoscopic injection needle (23G or smaller) via Luer lock. Device injects agent into submucosal layer to elevate mucosal tissue; facilitates subsequent excision of lesions via snare or other endoscopic tools. Brilliant blue dye provides visual contrast during resection. Benefits include improved visualization and tissue elevation for safer endoscopic mucosal resection.
Clinical Evidence
No clinical data. Substantial equivalence is supported by non-clinical bench testing, including sterilization validation (ISO 11137), packaging/aging (ASTM F1980, F2096, ISO 11607), biocompatibility (ISO 10993 series), and chemical characterization.
Technological Characteristics
Materials: Absorbable modified polymer (AMP) particles, 0.06% Brilliant blue (CAS 3844-45-9), plastic syringe. Sterilization: E-beam. Packaging: Aluminum film, PETG tray. Connectivity: None (manual).

## Device Description Summary
21 CFR 807.92(a)(4)
SIS BLU is intended for use in gastrointestinal endoscopic procedures for submucosal lift of polyps, adenomas, early stage cancers or other gastrointestinal mucosal lesions, prior to excision with a snare or other endoscopic device. SIS BLU is to be used in endoscopic resection procedures during endoscopic examinations in the upper and the lower gastrointestinal tract, such as the esophagus, the stomach, the intestine, the colon and the rectum. It is designed to elevate the mucosal layer and the tissue to be excised from the
{5}
K260997/S001 Page 2 of 3
submucosal and the external muscular layer. SIS BLU is a sterilized single use medical device that is composed of AMP BLU particles in a plastic bottle and a spiral plunger syringe. AMP BLU particles consist of an absorbable modified polymer and 0.06% Brilliant blue. The syringe is used to inject the agent (AMP BLU particles mixed with saline) into the submucosal layer. The syringe has a Luer lock fitting to ensure secure connection to a standard, commercially available endoscopic injection needle (e.g.: K142144 Disposable Injection Needle) having a needle diameter of 23 gauge (23G) or less. The agent can be injected by rotating the plunger. The syringe is compatible with the agent.
## Intended Use/Indications for Use
21 CFR 807.92(a)(5)
SIS BLU is intended for use in gastrointestinal endoscopic procedures for submucosal lift of polyps, adenomas, early stage cancers or other gastrointestinal mucosal lesions, prior to excision with a snare or other endoscopic device.
## Indications for Use Comparison
21 CFR 807.92(a)(5)
The subject and equivalent device share the same indications for use.
## Technological Comparison
21 CFR 807.92(a)(6)
The Proposed Device (SIS BLU, REF SISBLU-30-01, SISBLU-15-01, SISBLU-30-01 consists of 1g AMP BLU particles and a spiral plunger syringe, while SISBLU-15-01 is composed of 0.5g AMP BLU particles and a spiral plunger syringe, with the only difference between the two models being the AMP BLU particles fill quantity) and the legally marketed Predicate Devices (EndoClot SIS K191254; ORISE Gel K180068) are both Class II endoscopic submucosal injection systems, sharing Product Codes PLL and falling under regulatory classification 21 CFR 876.1500. Both devices are indicated for use in gastrointestinal endoscopic procedures for submucosal lift of polyps, adenomas, early stage cancers or other gastrointestinal mucosal lesions prior to excision with a snare or other endoscopic device.
Key differences include the proposed device contains brilliant blue dye (AMP BLU particles), whereas predicate device 1 (EndoClot SIS) has no dye component. The brilliant blue (CAS No: 3844-45-9) added is an FDA-approved food-grade dye, identical to the dye used in predicate device 2 (ORISE Gel). The proposed device requires mixing AMP BLU particles with normal saline before use, while ORISE Gel is pre-configured for direct use; such difference does not affect the core function or safety. Both devices use E-beam sterilization, aluminium film and PETG tray packaging, and have 2-year shelf life, all of which are consistent and compliant. Chemical characterization, toxicology assessment and biocompatibility tests verify that brilliant blue and AMP particles do not react to produce new substances, and all materials meet biocompatibility requirements. The technological characteristics, intended use, function and operation principle of injecting into submucosal layer under endoscopy remain the same between the proposed device and predicates. The only change is the addition of a safe, approved dye, which does not raise new safety or effectiveness issues.
Non-clinical testing confirms compliance with ISO 11137-1:2006, ISO 11137-3:2017, ISO/ASTM 52303:2015 for sterilization; ASTM F1980-21, ASTM F2096-11, DIN 58953-6:2023, ISO 11607-1:2019 for packaging and aging; and ISO 10993 series, ASTM F756-17 for biocompatibility.
In conclusion, the Proposed Device demonstrates substantial equivalence to the Predicate Devices in technical principles, clinical functionality, and safety thresholds. All differences represent design optimization with approved safe components without introducing new risks, satisfying FDA 510(k) substantial equivalence criteria for market authorization.

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 as a Medical Device, 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 as a Medical Device), 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.

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.
