Indications for Use
The PillCam Capsule Endoscopy System with a PillCam SB 2 and SB 3 capsules is intended for visualization of the small bowel mucosa. PillCam Capsule Endoscopy System with PillCam SB 2 and SB 3 capsules may be used in the visualization and monitoring of lesions that may indicate Crohn's disease not detected by upper and lower endoscopy. PillCam Capsule Endoscopy System with PillCam SB 2 and SB 3 capsules may be used in the visualization and monitoring of lesions that may be a source of obscure bleeding (either overt or occult) not detected by upper and lower endoscopy. PillCam Capsule Endoscopy System with PillCam SB 2 and SB 3 capsules may be used in the visualization and monitoring of lesions that may be potential causes of iron deficiency anemia (IDA) not detected by upper and lower endoscopy. The Suspected Blood Indicator (SBI) feature is intended to mark frames of the video suspected of containing blood or red areas. The PillCam Capsule Endoscopy System with PillCam SB 2 and SB 3 capsules may be used as a tool in the detection of abnormalities of the small bowel and is intended for use in adults and children from two years of age. The PillCam Capsule Endoscopy System with PillCam ESO 3 capsules is intended for the visualization of esophageal mucosa in adults and children from 18 years of age. The PillCam UGI capsule endoscopy system is intended for visualization of the upper gastrointestinal tract (esophagus, stomach, duodenum). It may be used for visualization of blood in the upper gastrointestinal tract (esophagus, stomach, duodenum) in patients who are hemodynamically stable and at least 18 years of age. The PillCam COLON 2 capsule endoscopy system is intended to provide visualization of the colon. It may be used for detection of colon polyps in patients after an incomplete optical colonoscopy with adequate preparation, and a complete evaluation of the colon was not technically possible. In addition, it is intended for detection of colon polyps in patients with evidence of gastrointestinal bleeding of lower GI origin. This applies only to patients with major risks for colonoscopy or moderate sedation, but who could tolerate colonoscopy and moderate sedation in the event a clinically significant colon abnormality was identified on capsule endoscopy.
Device Story
RAPID Web is a client-server software application for reviewing and analyzing capsule endoscopy videos. It functions as a web-based interface for studies previously captured by PillCam systems and stored in a central repository. Physicians access the system via secure internet or intranet browsers on workstations, laptops, or tablets (Apple iPads > 9.7"). The software allows clinicians to view, manage, and report on capsule endoscopy findings. By enabling remote access to study data, it facilitates efficient clinical review and decision-making regarding GI abnormalities, potentially improving diagnostic workflows and patient management. It does not perform initial capsule initialization or video creation, which are handled by the cleared RAPID 8.0 workstation software.
Clinical Evidence
Comparative performance study conducted with trained professionals identifying pathologies in identical video segments using both RAPID Web and RAPID 8.0 across various platforms (workstations, laptops, iPads). Analysis of matched and unmatched pathologies demonstrated that RAPID Web met pre-specified sensitivity requirements. Software validation performed per FDA guidance.
Technological Characteristics
Client-server software architecture; web-based deployment. Compatible with Windows (Chrome, Firefox, IE) and MacOS (Safari) environments. Supports viewing on workstations, laptops, and iPads (minimum 9.7" screen). Requires specific display standards (e.g., 20" monitor, 1600x900 resolution for workstations; 107 PPI for laptops). Connectivity via private intranet or secure internet. Does not include hardware; relies on existing PillCam capsule imaging hardware.
Indications for Use
Indicated for visualization of GI mucosa (small bowel, esophagus, upper GI, or colon) in adults and children (age 2+ for SB, 18+ for ESO/UGI/COLON). Used for monitoring Crohn's, obscure bleeding, iron deficiency anemia, or polyp detection post-incomplete colonoscopy. Contraindicated for patients unable to tolerate colonoscopy/sedation if required for follow-up.
Regulatory Classification

#### SUMMARY OF TECHNOLOGICAL CHARACTERISTICS VI.
The RAPID Web and RAPID 8.0 have the same intended use and indications, and similar technological characteristics and principles of operation. The only technological differences between the RAPID Web and its predicates are: relocation of software from local hard drive to web-based server, increased range of viewing platforms, removal of features intended for use on mainframes and PCs, removal of viewing modes and features not critical to diagnosis, and the addition of several user friendly features. These differences do not present any new issues of safety or effectiveness because they are not critical to diagnosis and primarily affect convenience. Thus, the RAPID Web is substantially equivalent to the RAPID 8.0.

#### VII. PERFORMANCE DATA
A comparative performance study wherein trained professionals identified pathologies in the same video and video segments that we displayed using RAPID Web and RAPID 8.0 was performed. RAPID 8.0 performance was assessed on multiple platforms, including workstations, laptops, and iPads. An analysis assessing the matched and un-matched pathologies showed that RAPID 8.0 met the pre-specified sensitivity.
In addition, the software was validated and documented per FDA's software guidance document.
#### VIII. CONCLUSIONS
The RAPID Web is as safe and effective as the RAPID 8.0. The RAPID Web has the same intended uses and indications, and similar technological characteristics, and principles of operation as its predicate device. The minor differences in indications do not alter the intended diagnostic use of the device and do not affect its safety and effectiveness when used as labeled. In addition, the minor technological differences between the RAPID Web and its predicate devices raise no new issues of safety or effectiveness. Performance data demonstrate that the RAPID Web is as safe and effective as the RAPID 8.0. Thus, the RAPID Web is substantially equivalent.
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.
