Intended use - To provide improved mobility, both indoors and outdoors, for persons who have adequate upper body strength suitable for manual steering, and who have a medical condition that impairs their ability to stand for periods of time or to walk.
Description of the device - Navigator I was designed to assist individuals with limited mobility to maintain an active lifestyle. Its manual steering, high-torque four brush motor with rear wheel drive, large diameter (16") front wheels, high ground clearance (5.4"), full circle turning radius (27.5"), side to side anti-tip resistance, and curb climbing (5.5") ability make it a versatile vehicle equally adept in the shopping mall, on firm surface wilderness trails, or in the close quarters of a restaurant or home kitchen. Navigator I is a blended hybrid drawine elements from both scooters and wheelchairs, to meet desired features requested by long term scooter users. It does this while still maintaining the three-wheel scooter configuration with manual steering and anti-tip wheels adjacent to the single steering wheel. Navigator I is an clectronically controlled motorized 3-wheeled vehicle employing a rear single wheel remotely steerable motor drive system (11.5" tire). It employs a 24 Volt DC permanent magnet motor powered by two 12 Volt scaled lead acid deep cycle batteries. The rigid Front Frame Assembly holds the two batteries, mounts the two front 16" diameter wheels, the two front hand controlled parking brakes, the swing up front foot rests, the electronic motor controller, and the steering arm with handle incorporating the 6-position variable speed-control. The Rear Frame Assembly is made up of the rear motor drive, the swing out Anti-tip wheels, the rear bearing block assembly and pivot wheel assembly. The Front and Rear Frame Assemblies are connected together by two semi-rigid Torsional Elements™ (relatively rigid to a vertical load, but allowing limited rotation), which also support the scat block mounting assembly. The Torsional Elements™ allow limited twist (similar to the Articulation Beam in the Pride Jazzy, K945936) to occur between the Front and Rear Frame Assemblics up to 5° of rotation, at which point one Anti-tip wheel with the ground. This greatly enhances side to side stability when driving Navigator I over rough terrain, since Navigator I is smothly transformed from three wheels to four wheels with ground contact on all four wheels.
Substantial equivalence - The Navigator I design is shown to be substantially cauvalent to the motorized threewheeled scoolers that were classified in class II under 21 CFR Section 890,3800. The basic three-wheeled scooter design is augmented with a patented frame design with anti-tip wheels that improve stability. Navigator I is a blended hybrid drawing features primarily from scooters, with some mechanical wheelchair features to improve safety and effectiveness, as outlined in the list of specific features from the predicate devices listed above and detailed in this 510(k).
Safety and effectiveness - The Navigator I Powered Scooter is substantially equivalent to the technology cmployed in the predicate devices listed in this 510(k). Navigator I docs not raise any new issues of salety and clectiveness. The occupant initiated swing-out anti-tip wheels allow the occupant to readily improve resistance to side-tip and the Torsional Elements™ provide both a smooth ground engagement of the anti-tip wheels and a side-tip warning mechanism via front wheel pickup, which we have shown by testing to significantly improve occupant safety.

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.
