# omparison to Predicate Device:
omponents of the predicate, Connex Gastrointestinal Suture Anchor Set and th components on the predicate, Connex Gastronitestinal Suture Anchor Set and diustable Gastrointestinal Suture Anchor Set are identical, and consist of the wire guides, introducer needles, suture, and the suture anchors.
the proposed devices are substantially equivalent to the predicate in terms of in increation, the proposed as rises and such in the mical location, and method of sterilization.
ence in the technological characteristic of the predicate device and the proposed d the suture anchoring mechanism. The predicate, Connex Gastrointestinal Suture Anchor Set intine suture anonoming moonamants The produced. Connell wall by an anchoring mechanism aich consists of disks and crimp beads.
e suture retention mechanism of the Entuit™ Secure Gastrointestinal Suture Anchor Set
intains the retention of the suture anchor to the abdominal wall by passing the suture t extension spring inside the suture retention mechanism housing. Whereas, the Entuit™ Secure divisiable Gastrointestinal Suture Anchor Set maintains the retention of the suture anchor to the ominal wall by threading the suture through the retention housing with the suture held in ce by a compression jaw and spring. The adjustable tab is removable and can be used to adjust the suture.
## evice Description:
The Entuit™ Secure Gastrointestinal Suture Anchor Set and the Entuit™ Secure A astrointestinal Suture Anchor Set consist of 2 or 3 introducer needles with pre-loaded suture nors and a wire guide. A notch is located on the distal tip of the introducer needle. The coil chor is placed in the notch prior to placement. The proximal end of the suture anchor ntains the suture retention mechanism.
e retention mechanism of the Entuit Secure Gastrointestinal Suture Anchor consists of an
ension spring which is glued on the proximal end within a suture retention housing. T ture is threaded through the coils of the extension spring. When the suture retention echanism is pushed towards the anchor, tension is applied to the spring, which causes the coils he spring to open. This allows the suture to slide through the spring and allows the retention echanism to slide along the suture. When the retention mechanism is pulled away from the
{2}------------------------------------------------
anchor, the coils of the spring compress and clamp down on the suture. This does not allow the suture to slide through the spring and maintains tension on the suture anchor.
The adjustable suture retention mechanism of the Entuit Secure Adjustable Gastrointestinal Suture Anchor Set consists of a suture retention housing, a compression spring, a compression jaw, and a removable adjustable tab. The suture is threaded through the suture retention housing and held in place by the compression jaws and the compression spring. The adjustable tab must be compressed for the suture to be adjusted. When the adjustable tab is compressed, the spring and compression jaws do not contact the suture. This allows the suture retention mechanism to slide along the suture. Once the suture retention mechanism is in place, the compression jaws will maintain tension on the suture anchor, and the adjustable tab can be removed.
Both of the proposed devices are supplied sterile and are intended for one-time use.
## Comparison of Technological Characteristics:
The Entuit™ Secure Gastrointestinal Suture Anchor Set and the Entuit™ Secure Adjustable Gastrointestinal Suture Anchor Set were subjected to the following tests to assure reliable design and performance under the specified testing parameters:
- 1. Tensile Testing Testing shows that the tensile strength during proper clinical use of the devices should be capable of maintaining the proper tensile force requirements to anchor the anterior wall of the stomach to the abdominal wall. Testing demonstrated that the device met all predetermined acceptance criteria.
- 2. Fatigue Testing Testing shows that under normal clinical use of the devices there should be no mechanism or suture failure.
- 3. Biocompatibility Testing Testing (i.e., cytotoxicity, sensitization, intracutaneous and systemic toxicity, and pyrogenicity) shows that the devices are biocompatible. In conformance with the applicable sections of ISO 10993-1, the predetermined acceptance criteria were met.
The Entuit 110 Secure Adjustable Gastrointestinal Suture Anchor Set was also subjected to torque testing. Testing shows that the device can withstand the torsional forces seen during proper clinical use.
Testing demonstrated that the Entuit™ Secure Gastrointestinal Suture Anchor Set and the Entuit™ Secure Adjustable Gastrointestinal Suture Anchor Set met all predetermined acceptance criteria.
## Conclusions Drawn from the Tests:
The results of these tests provide reasonable assurance that the Entuit™ Secure Gastrointestinal Suture Anchor Set and the Entuit™ Secure Adjustable Gastrointestinal Suture Anchor Set are as safe and effective as the predicate device and support a determination of substantial equivalence.

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.
