| | System Connector Plug) | |
| | FC 3000S-8R (Siemens MR Systems @ 123.23MHz with Siemens<br>● | |
| | System Connector Plug) | |
| | | |
| | The coil suites include two different sets of coil paddles and a single,<br>shared preamplifier box (the "Connector Box") with a system | |
| | connector. One set contains a pair of coil paddles containing four 24cm | |
| | loops/channels per paddle for a total of eight channels for the two | |
| | paddles. The second set contains a pair of coil paddles containing four | |
| | 10cm loops/channels per paddle for a total of eight channels for the | |
| | two paddles. These paddles connect to the same connector box | |
| | containing eight preamplifiers; only one pair can be connected at a | |
| | time. The coil design for all the paddles has the same, simple antennae | |
| | design and the same system connectivity configuration. The coils can be | |
| | used in the following configurations: | |
| | 24cm by itself<br>● | |
| | 24cm with 24cm 24cm with 10cm 10cm with 10cm The aforementioned configurations provide 4 or 8 channels for imaging. | |
| Intended Use: | The 1.5T GE and Siemens DuoFLEX® Coil Suites and the 3.0T GE and<br>Siemens DuoFLEX® Coil Suites are indicated for use on the order of a<br>physician in conjunction with a 1.5T GE Healthcare and Siemens<br>Healthcare Magnetic Resonance Scanner system and a 3.0T GE<br>Healthcare and Siemens Healthcare Magnetic Resonance Scanner<br>system to produce 2D and 3D images that when interpreted by a<br>trained physician yield information that may assist in diagnosis. | |
| Comparison of Technological<br>Characteristics: | The subject devices and the predicate device are identical except for<br>the following differences: Increased coil cable length by 12" Replaced system cable with foam segments Decreased system cable length by 6" Added cylindrical balun to the system cable Added an additional cylindrical balun to the coil cable Improved & updated internal electronics Three (3) of the Coil Suites' field strength and frequency: Predicate Device = 1.5T @ 63.86MHz Subject Devices That Differ: 1.5T @ 63.6MHz 3.0T @ 127.73MHz 3.0T @ 123.23MHz Two (2) of the Coil Suites' System Connector Plugs: Predicate Device = GE System Connector Plug Subject Devices = Siemens System Connector Plug | |
| | The subject devices and the predicate device use the same technology<br>to perform the same function which is the use of Magnetic Resonance<br>Imaging systems to provide images of various body parts. The MR<br>Instruments' 1.5T DuoFLEX® Coil Suite (K130706) is designed to be used<br>either as a pair of coils or as a single coil, and is designed to be flexible<br>enough to accommodate itself to various anatomical positions. These<br>same statements can be made for the new variations of the DuoFLEX®<br>Coil Suites. | |
| Summary of Technical<br>Comparisons: | The comparison of the DuoFLEX® Coil Suites to the predicate device<br>with respect to intended use, target population, technological<br>characteristics, and principles of operation confirms substantial<br>equivalence. The fundamental performance and functional<br>characteristics of the DuoFLEX® Coil Suites are identical to the predicate<br>1.5T DuoFLEX® Coil Suite (K130706). | |
| Non-Clinical Testing: | The following bench testing was conducted on the DuoFLEX® Coil<br>Suites: EMC and electrical safety testing | |
| • | System safety testing | |
| • | Performance testing with phantoms | |
| • | Predicate device comparison tests | |
| • | Volunteer scans | |
| • | Per IEC 60601-1: | |
| | ○ Humidity Preconditioning for Dielectric Test | |
| | ○ Determination of Accessible Parts | |
| | ○ Legibility of Markings | |
| | ○ Durability of Markings | |
| | ○ Dielectric Strength | |
| | ○ Ball Pressure | |

Conclusion: We conclude that the results of testing show the DuoFLEX® Coil Suites to be substantially equivalent to the predicate device. The DuoFLEX® Coil Suites have the same technological and functional characteristics as the predicate device in that all devices are receiveonly RF coils intended for use with MRI equipment. The DuoFLEX® Coil Suites have the same intended use as the predicate device in that all devices are intended for diagnostic imaging. lt has been shown in this 510(k) submission that the difference between the DuoFLEX® Coil Suites and the 1.5T DuoFLEX® Coil Suite (K130706) do not raise any questions regarding safety and effectiveness. The DuoFLEX® Coil Suites, as designed and manufactured, are substantially equivalent to, and as safe and effective as, the referenced predicate device.

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.
