E. System Descriptions:
1. Device Description:
The Ikoniscope fastFISH Auto/Amniocyte Test System is an automated scanning microscope system incorporating automated slide loading and handling, low and high magnification scanning to identify targets of interest and digital image acquisition, coupled with an image analysis workstation. Microscope slides, prepared according to the DNA probe manufacturers' specifications, are placed into a multiple slide cassette, and loaded into the Ikoniscope fastFISH Auto/Amniocyte test system. The system unloads each slide, scans each one, and returns it to the cassette automatically. During scanning, images of cells exhibiting the predetermined characteristics for FISH signals are digitally photographed and stored. After all the slides are scanned, the workstation provides a summary of the FISH signals detected for each chromosome of interest and an image gallery that displays the image of each cell nucleus meeting predetermined characteristics and quantity. The operator/reader can then evaluate the condition of the cells and make the diagnostic determination accordingly.
2. Principles of Operation:
The Ikonisys fastFISH Auto/Amniocyte Test System combines elements of existing technologies to perform its function. Fluorescence In-Situ Hybridization (FISH) uses commercially available DNA probes (not supplied with the test
{1}
system) for marking chromosomes 13, 18, 12, X and Y. Automated cell locating/counting uses pattern recognition algorithms to identify the signal characteristics of interest. The Ikoniscope software automatically captures several sets of images of each nucleus containing FISH signals and stores its location on the slide. These images are then presented to the operator, using a computer workstation for analysis.

J. Performance Characteristics:
1. Analytical Performance:
a. Accuracy:
The purpose of the four-center study was to provide evidence to establish the equivalence of the fastFISH Auto/Amniocyte Test System against scanning by conventional means in the examination of amniocyte slides prepared using FISH. The study included 262 slides from 131 patients. Amniocytes were obtained by amniocentesis from pregnant females scheduled for invasive sampling for karyotyping unrelated to participation in this study.
Results: A diagnostic outcome was reported for 125 of 131 (95%) samples in the test arm of the trial and in 131 of 131 of the samples in the standard/control arm. In the investigational device arm a fully-automated diagnostic outcome was produced for 100 samples (76%) and following review for the remaining 25 samples (19%). Of those samples for which a fully-automated result was obtained, 15 required re-scanning, per the protocol. Diagnostic conclusions determined by the investigational and standard FISH analysis for all 125 samples for which both results were available, was identical for all of the chromosomes examined (X, Y, 13, 18, and 21). The concordance rate for this trial was 100% for those samples for which a comparison was possible.
b. Precision/Reproducibility:
The purpose of the study was to demonstrate the reproducibility of results using the Ikoniscope fastFISH Auto/Amniocyte Test System between systems, operators, and days of operation. All samples were processed and evaluated in a blind fashion. A total of 100 slides were selected from the comparison study.
{5}
Results: All slides provided an automated diagnostic outcome and none returned a “review required” outcome. Of the 100 slides, 60 were CEP (Centromeric Probes) and 40 were LSI (Locus specific Probes) slides. All of the CEP slides produced a result for chromosomes X, Y, and 18 based upon 50 nuclei. For the LSI slides, 36 (90%) produced an automated diagnostic outcome based upon 50 nuclei, while in 4 (10%) of LSI slides the diagnostic result was based upon fewer than 50 nuclei, according to the analysis algorithm. This compares to 7% of LSI slides analyzed in the comparison study. This slight increase, which is not statistically significant, could be related to the fact that these slides had been previously scanned possibly resulting in some bleaching of the LSI fluorophores. There was 100% diagnostic concordance for each chromosome (X, Y, 13, 18, and 21).

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.
