Legally Marketed Devices to Which your Firm is Claiming Equivalence: The Colonplus Colonkits (Small, Large, Large with Stop Collar 6 and Large with Stop Collar 10) are substantially equivalent in intended use, indications for use, and design to the Prime Pacific Health Innovations Corporation Pro-Fit™ disposable speculum (Regular and Small size) cleared on March 15, 2005 under Pre-market Notification 510(k) number K050112. In addition, it is substantially equivalent in intended use, indications, design, and materials to the Hydrokit from Transcendencias Comerciales, S.L cleared on April 17, 2014 under Pre-Market Notification 510(k) K131852.
{4}------------------------------------------------
Description of the Device: The disposable rectal speculum is a non-metal (Polypropylene) device used to introduce water into the colon and dispose waste from the colon during a colonic irrigation procedure.
Intended Use of the Device: The device is intended for colon cleansing when medically indicated, such as before radiological or endoscopic examinations.
### Technological Characteristics Compared to Predicate Device:
The Colonplus Colonkits have the same technological characteristics as, and are substantially equivalent to the Pro-Fit™ Disposable Speculums (K050112), manufactured by Prime Pacific Health Innovations Corporation (See Figure 5A, 5B, and 5C). Both products are to be used with colon hydrotherapy equipment. The Colonplus Colonkit large was designed with two variations including a stop collar (insertion stopper) with an irrigation water entrance with diameter of 6 mm and 10 mm, respectively. The Pro-Fit™ speculum, released per 510(k) K050112, was designed with an insertion stopper to avoid over insertion, as well. The design of the Colonplus Colonkit cannula with obturator is also substantially equivalent to the speculum in the Hydrokit predicate with Pre-market Notification 510(k) K131852. Both have models with and without stop collar. Refer to Figures 5D and 5E below.
Image /page/4/Picture/4 description: The image shows a white plastic part with a stop collar. The stop collar is located near the middle of the part. The part has a pointed end and a cylindrical body. There is an arrow pointing to the stop collar with the text "Stop Collar".
Figure 5A Predicate Pro-Fit™ Disposable Speculum (with stop collar/limit)
Image /page/4/Picture/6 description: The image shows a medical device with an arrow pointing to the stop collar. The stop collar is a ring-shaped component that is part of the device. The device appears to be made of clear plastic and has a cylindrical shape. The text "Stop Collar" is written next to the arrow.
Figure 5B Colonplus Colonkit (cannula with stop collar)
{5}------------------------------------------------
Image /page/5/Picture/0 description: The image shows a medical device, possibly a catheter or similar instrument, against a dark background. The device is translucent and cylindrical, with several attachments or ports along its length. It appears to be made of plastic or a similar material, and its design suggests it is intended for insertion into the body for medical purposes.
Figure 5C Colonplus Colonkit (cannula without stop collar)
Image /page/5/Picture/2 description: The image shows a medical device in a clear plastic bag. The device is white and has a cylindrical shape with a ring on one end. There are also a couple of tubes coming out of the side of the cylinder. The device appears to be a catheter or some other type of medical instrument.
Figure 5D Polypropylene Predicate Hydrokit (cannula without stop collar)
Image /page/5/Picture/4 description: The image shows medical tubing and equipment on a black background. There is a long, corrugated tube coiled on the left side of the image. There is also a smaller, clear tube coiled in a circle. A stop collar is labeled on the right side of the image.
Figure 5E Polypropylene Predicate Hydrokit (kit including cannula with stop collar)
The Colonplus Colonkit cannula and obturator are made out of polypropylene, in contrast to the ProFit™ which is made out of polyethylene. Polypropylene has good impact strength, surface hardness, dimensional stability and excellent abrasion resistance. The finished colonkit was tested for biocompatibility by Laboratorio BIOLAB S.L in Spain. When compared with predicate 510(k) K131852 Hydrokit from Transcendencias Comerciales S.L, both are made out of polypropylene and have the same intended use and indications for use, which supports the substantial equivalence of materials.
The kit components of the Colonkits (irrigation tube and evacuation tube) are also substantially equivalent to those included in the ProFit™ disposable speculum kit (water line and
{6}------------------------------------------------
water hose) manufactured by Prime Pacific Health Innovations Company through 510(k) K050112.
### Indications for use
The device is intended for colon cleansing when medically indicated, such as before radiological or endoscopic examinations.
### Summary and Conclusions from the Nonclinical Tests Submitted:
Substantial equivalence of the Colonplus Colonkit System is supported by a comparison of the intended use, indications for use, and design with the Pro-fit™(K050112) and by a comparison of the intended use, indications for use, design and materials to the Hydrokit (K131852), as well as acceptable results from biocompatibility test.

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.
