# Difference Analysis
The subject device and the primary predicate device have the same intended use of providing indoor and restricted outdoor mobility to disabled or elderly persons who are limited to a seated position. Both devices are battery-powered, four-wheeled mobility scooters that use a rear-wheel-drive system, an electromagnetic braking system, a user-operated throttle control, an off-board battery charger, and anti-tip devices. The selected predicate model, MJMA01, is not equipped with armrests, which is consistent with the subject device. Therefore, the subject device and the primary predicate device have the same fundamental scientific technology.
The subject device differs from the predicate device in overall dimensions, wheel diameters, ground clearance, turning radius, and total mass. These dimensional and configuration differences could potentially affect maneuverability, static and dynamic stability, obstacle negotiation, and transportation or handling of the device. The subject device was evaluated in its final production-equivalent configuration in accordance with the applicable provisions of ISO 7176-1, ISO 7176-2, ISO 7176-5, ISO 7176-7, ISO 7176-8, and ISO 7176-10. The test results demonstrated acceptable static and dynamic stability, dimensional characteristics, structural strength, fatigue resistance, and obstacle-climbing performance. Therefore, these differences do not adversely affect the safety or effectiveness of the subject device.
**The frame** of the subject device is manufactured from carbon fiber, whereas the frame of the predicate device is manufactured from aluminum alloy. The difference in frame material could potentially affect structural strength, impact resistance, fatigue durability, and the mode of structural failure. However, the safety of the finished mobility scooter is determined by the structural performance of the complete device rather than by material identity alone. The subject device was subjected to the applicable static strength, impact strength, and fatigue strength tests specified in ISO 7176-8 at the required test loads. The completed device maintained its structural integrity and functional performance following testing. The carbon-fiber frame therefore does not raise different questions of safety or effectiveness.
**The maximum occupant mass** of the subject device is 182 kg, compared with 120 kg for the predicate device. The increased occupant mass could affect structural loading, stability, braking performance, propulsion-system loading, and battery consumption. These potential effects were evaluated by conducting the applicable ISO 7176 performance tests using the specified maximum occupant mass or the corresponding test load required by the applicable standard. The subject device met the applicable acceptance criteria for static stability, dynamic stability, braking effectiveness, structural strength and fatigue, power and control systems, and maximum speed. K192308 is cited only as a reference device to demonstrate that a maximum occupant mass of 182 kg is an established performance characteristic for a legally marketed mobility scooter. Substantial equivalence remains primarily supported by comparison with K253936 and by the performance testing conducted on the subject device.
{8}
The subject device uses a 24 V, 180 W motor, one 24 V, 10.4 Ah lithium-ion battery, and an off-board charger, whereas the predicate device uses a 24 V, 250 W motor, two 24 V, 5.8 Ah lithium-ion batteries, and a charger with different output characteristics. These differences could affect propulsion performance, energy consumption, theoretical driving range, charging performance, electrical safety, and thermal performance. The subject device was evaluated in accordance with ISO 7176-4, ISO 7176-6, ISO 7176-14, ISO 7176-21, and ISO 7176-25. The results demonstrated that the propulsion, control, battery, charger, maximum-speed, range, and electromagnetic-compatibility performance of the subject device met the applicable requirements and the manufacturer's specifications. Therefore, the differences in the motor, battery, and charger do not raise different questions of safety or effectiveness.
**The maximum forward speed** of the subject device is 6.12 km/h, which is lower than the 6.84 km/h maximum speed of the predicate device. At its measured maximum forward speed of 1.7 m/s on a horizontal surface, the subject device demonstrated a braking distance of 1.0 m during normal braking operation. No abnormal behavior, including tipping, sliding, brake failure, or veering, was observed during the braking tests. The subject device also met the applicable requirements for reverse-command braking, emergency braking, and downhill braking under the tested conditions. These results demonstrate that the braking system provides adequate stopping performance for the subject device's specified speed and maximum occupant mass.
**The maximum safe slope** specified for the subject device is 8°, compared with 10° for the predicate device. The subject device therefore has a more restrictive labeled operating limitation. The subject device was tested for braking and stability under the applicable inclined-plane conditions, and the 8° maximum safe slope is disclosed in the labeling. The difference does not increase user exposure to slope-related hazards when the device is operated in accordance with the Instructions for Use.
**The theoretical driving range** of the subject device is 10.1 km, compared with 16.3 km for the predicate device. Driving range is a performance characteristic and does not alter the intended use or fundamental operating principle of the device. The subject device provides a battery-status indication, and the specified driving range and charging instructions are disclosed in the labeling. Accordingly, the shorter theoretical driving range does not raise different questions of safety or effectiveness.
Based on the same intended use, the same fundamental scientific technology, the comparison with the primary predicate device, and the results of the applicable nonclinical performance testing, the identified technological differences do not raise different questions of safety or effectiveness. The submitted test results demonstrate that the subject device is as safe and effective as the legally marketed predicate device.

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).

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.
