Indications for Use
The Endotracheal tube is intended for oral or nasal intubation and for airway management. The Reinforced Endotracheal tube is intended for airway management by oral or nasal intubation of the trachea during anesthesia. It is a device inserted into the trachea through the mouth or nose to facilitate breathing and it may be used where the patient's neck is likely to be moved of flexed or the patient is in the prone position so that a non-reinforced tracheal tube might become kinked.
Device Story
Disposable endotracheal tubes (ETTs) and reinforced ETTs facilitate airway management and artificial ventilation. Standard ETTs consist of a PVC tube, connector, and optional cuff/inflation system; reinforced ETTs include a 304 stainless steel wire spiral for kink resistance. Used in ORs and ICUs by clinicians for oral or nasal intubation. Devices are inserted into the trachea to establish a patent airway. Cuffed variants provide a tracheal seal to route gases. Reinforced variants are used when patient positioning (e.g., prone, head/neck surgery) risks tube kinking. Devices are supplied sterile, single-use, and intended for short-term use (up to 30 days).
Clinical Evidence
No clinical data. Substantial equivalence supported by non-clinical bench testing, including biocompatibility (ISO 10993-1), sterilization validation (ISO 11135-1), and performance testing (ISO 5361:2012) covering dimensions, cuff integrity, kink resistance, and mechanical properties.

### 5. Device Description
The Endotracheal tubes are used for oral or nasal intubation and for airway management, which are mainly for patients that require repeated anesthesia, artificial ventilation and assisted breathing. The Endotracheal tube is available in cuffed and uncuffed variants. The cuff is intended to provide a seal against the trachea, ensuring that inspiratory and expiratory gasses are routed through the tube and not allowed to escape to the patient's upper airway. The structure of Cuffed Endotracheal tube contains a main tube (patient end, machine end and murphy eye), cuff, and inflating system (including inflating tube, valve and pilot balloon). The uncuffed Endotracheal tube contains main tube (patient end, shaft and machine end). All variants have a Murphy eye. The products are primarily made from polyvinyl chloride (PVC) materials. The Endotracheal tubes are available in a number of sizes: the nominal inside
{5}------------------------------------------------
diameter of uncuffed Endotracheal tubes are from 2.0mm to 10.0mm; the nominal inside diameter of cuffed Endotracheal tubes are from 2.5mm to 10.0mm. The Endotracheal tubes are disposable and are supplied sterile. The contact time should be no more than 30 days.
The reinforced Endotracheal tubes are a tracheal tube with additional metal wire spiral reinforcement to provide kink-resistance. The products are always used during operations where a high degree of flexibility is required from the tube. The reinforced Endotracheal tubes are also available in cuffed and uncuffed variants, and nominal inside diameter of both the uncuffed and cuffed reinforced Endotracheal tubes are from 3.0mm to 9.0mm. The only difference between reinforced Endotracheal tubes and Endotracheal tubes is the metal wire spiral inside the tube, which is made by 304 stainless steel and used for reinforcement that maintains the patency of the lumen.
## 6. Indications for Use Statement
The Endotracheal tube is intended for oral or nasal intubation and for airway management.
The Reinforced Endotracheal tube is intended for airway management by oral or nasal intubation of the trachea during anesthesia. It is a device inserted into the trachea through the mouth or nose to facilitate breathing and it may be used where the patient's neck is likely to be moved of flexed or the patient is in the prone position so that a non-reinforced tracheal tube might become kinked.

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.
