#### 4. Indications for Use Statement: '
The Foresee (4C) Imaging System is intended to be used as an imaging tool in the evaluation of external human tissue microstructure by providing two-dimensional, crosssectional, real-time depth visualization.
{1}------------------------------------------------
#### 5. Technological Characteristics:
The Foresee (4C) Imaging System uses optical coherence tomography (OCT) to create images of tissue. OCT is an imaging technology similar to ultrasound except that images are formed using reflected light rather than reflected sound. In place of sound waves, OCT uses a near-infrared beam of light that penetrates tissue. The light reflects off of changes in tissue microstructure. Using the principles of low-coherence interferometry, a technique that measures the interference of light from a sample arm and a reference arm to create an image, OCT produces a high-resolution depth profile. Scanning the beam across tissue produces a detailed, two-dimensional image of tissue microstructure morphology.
The Foresee (4C) Imaging System uses a broadband, swept optical source and a fixed reference arm to acquire imaging data in the frequency domain. The Foresee (4C) Imaging System has a handheid probe for the scanning of tissue. The probe has a fixed focal depth with a correction for beam diffraction employing a physics-based, software signal processing technique.
The Foresee (4C) Imaging System consists of a cart-mounted imaging console with an isolation transformer; a foot pedal; a handheld imaging probe with a single-use non-sterile disposable probe tip: an imaging module containing a light source, interferometer, and detector; and an imaging computer that implements physics-based software signal processing; and dual monitors for image display. The system user interface allows the viewing, capture, review and export of images.
#### 6. Performance Data:
The Foresee (4C) Imaging System is designed and tested to be in compliance with international standards (noted in Table 1 on the following page) concerning safety for electrical and mechanical safety, electromagnetic emissions and susceptibility, biocompatibility, disinfection, and laser safety. Key features of the system design related to electrical safety and electromagnetic compatibility include an isolation transformer for system power; a shielded and arounded enclosure meeting requirements for fireproof enclosure; and a double insulated probe housing and cable for patient protection. The system has been tested for electrical and mechanical safety for Medical Electrical Equipment and for electromagnetic compatibility as specified in Table 1 on the following page. The system uses a laser that is limited in power to meet the requirements of a class 1 laser device in accordance with IEC 60825-1:2007.
The handheld probe has been designed to be a reusable component and to support cleaning and low level disinfection. A process has been developed and validated for reprocessing of the reusable handheld probe (see details in Section XVI). The single use probe tip has been designed using materials that adhere to the requirements for skin surface limited (<24 hours) contact. The complete single use probe tip has been tested for Biocompatibility per ISO 10993 based on the intended use.
The system image performance has been tested to evaluate the in-depth spatial resolution. in-depth image range, lateral spatial resolution, lateral image range and scan linearity deviation. Imaging of the esophagus, bladder, and colon from healthy New Zealand white rabbit was performed to study the performance of the Foresee (4C) Imaging System in comparison to published predicate data from the Imalux OCT Imaging System and to demonstrate the imaging capabilities of the Foresee (4C) Imaging System for the visualization of tissue microstructure in tissue specimens. The standards that the system has been tested against assure the safety of the device and are listed on the following page.

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.
