# Device Description:
The TurboSEAL™ Nasogastric Aspiration Tube (NGAT) is a typical Nasogastric Tube (NGT) allowing for enteral feeding, gastric decompression and gastric lavage. Connection of the device to standard hospital suction enables the application of suction to two separate locations (the Distal and Proximal Aspiration Areas) located at the distal end of the device. Aspiration at these sites allows for the removal of gastric fluid that has entered the esophaqus. Aspiration is limited to one aspiration site at a time, for a maximum duration of 5 hours at each site.
# Intended Use. Indications for Use. Contraindications:
The TurboSEAL™ Nasogastric Aspiration Tube (NGAT) is intended for gastric decompression, gastric lavage and the administration of nutritional supplements through the distal tube port. It is also indicated for the aspiration of small quantities of refluxed gastric fluid from the distal esophaqeal aspiration areas.
The TurboSEAL™ NGAT is contraindicated for pregnant women, pediatric, and neonatal use.
{6}------------------------------------------------
# Comparison of Indications for Use / Intended Use:
- . Intended Use Comparison
- The TurboSEAL™ NGAT and the predicate Davol® Nasogastric Sump Tube O have similar intended uses. Both devices are intended for gastric decompression, gastric layage, and the administration of nutritional supplements,
- The TurboSEAL™ NGAT and the predicate Moss Mark IV Nasal Tube have O similar intended uses. Both devices are intended for gastric decompression, administration of nutritional supplements, and gastric fluid aspiration.
- Indications for Use Comparison .
- The TurboSEAL™ NGAT and the predicate Davol® Nasogastric Sump Tube o have similar indications for use. Both devices are indicated for gastric decompression, gastric lavage, and the administration of nutritional supplements.
- The TurboSEAL™ NGAT and the predicate Moss Mark IV Nasal Tube have O similar indications for use. Both devices are indicated for gastric decompression, enteral feeding (je administration of nutritional supplements), and gastric fluid aspiration. Although the cleared indications for the Moss Mark IV Nasal Tube do not specifically state that the device is indicated for gastric fluid aspiration: the cleared instructions for use for the product specifically point to a number of aspiration areas on the device diagram. The aspiration areas are described as the "Esophageal [Aspiration] Orifices," "Gastric Aspiration Orifices," and "Duodenal Aspiration Orifices." Therefore, the Moss Mark IV Nasal Tube is also indicated for gastric fluid aspiration within the Instructions for Use cleared for the device.
- The TurboSEAL™ NGAT is substantially equivalent to the indications for use of o both predicate devices. The TurboSEAL™ NGAT has no additional indications for use beyond those of the predicate devices.
## Comparison of Technological Characteristics:
The TurboSEAL™ NGAT has similar technological characteristics as compared to its identified predicate devices. All are multilumen nasogastric tubes that allow of the bidirectional movement of fluids in and out of the gastrointestinal (GI) tract.
- . Gastric Decompression
- o Gastric decompression involves the removal of fluids and/or gas from the stomach to relieve excess gastric pressure. Gastric decompression is indicated by all three devices, and is achieved by using a lumen within the tube to vent excess pressure.
- . Gastric Lavage
- Gastric lavage is the process of introducing and subsequently removing fluids o from the stomach to cleanse the contents of the stomach. Both the TurboSEAL™ NGAT and the Davol® Nasogastric Sump Tube are indicated for gastric lavage.
{7}------------------------------------------------
- Administration of Nutritional Supplements ●
- All three devices are indicated for the administration of nutrition. Nutrition is o administered through the use of valves and polymeric tubing providing a direct fluid path between the nutritional supplement source (eg feeding bag or feeding pump) and the GI tract of the patient.
- . Gastric Fluid Aspiration
- Gastric fluid aspiration is the process of removing air and/or fluid from the GI tract o using a negative pressure source. Both the TurboSEAL™ NGAT and Moss Mark IV Nasal Tube are indicated for gastric fluid aspiration. Gastric fluid aspiration is achieved in both devices by applying negative pressure to the tube, causing the aspiration of fluid at various aspiration areas (ie aspiration orifices) along the length of the tube. The Moss Mark IV Nasal Tube contains esophageal, gastric, and duodenal aspiration areas. The TurboSEAL™ NGAT has nearly identical esophageal aspiration areas, and does not contain gastric or duodenal aspiration areas.
## Summary of Performance Testing:
TurboSEAL, L.P. has performed extensive verification and validation testing to demonstrate the substantial equivalence of the TurboSEAL™ NGAT to the Davol® Nasogastric Sump Tube and the Moss Mark IV Nasal Tube. The TurboSEAL™ NGAT has been subjected to safety, performance, verification and validation testing to ensure that the device meets all of its functional requirements and intended uses. Testing has been performed to ensure that the device complies with all applicable industry and safety standards. The following list summarizes the testing performed on the TurboSEAL™ NGAT:
- Biocompatibility
- Sterilization ●
- Packaging ●
- Shelf Life
- . Dimensional Inspection
- Liquid Leakage Testing
- Visual Inspection
- Tensile Strength Testing
- Simulated Use
●
- Gastric Fluid Compatibility
- Porcine Animal Study
- o Visual Examination (Gastroscopy)
- o Histology
- Human Factors/Usability o
As demonstrated by the results of the verification and validation testing, the minor differences in technological characteristics between the TurboSEAL™ NGAT and its predicate devices do not raise different questions of safety and effectiveness.
{8}------------------------------------------------
# Conclusion:
The TurboSEAL™ NGAT is substantially equivalent with respect to the intended use/indications for use, technological characteristics, target user, patient population, and use environment to the following the legally marketed predicate devices:
- Moss Tubes, Inc. Nasal Tube Mark IV, K984629 .
- Davol® Nasogastric Sump Tube with PreVent™ Anti-Reflux Filter, Davol Inc. (A Bard . Company), K960176
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.
