Indications for Use
Applied Medical's Inzii Ripstop Redeployable Retrieval System is indicated for use as a receptacle for the collection and extraction of tissue, organs, and calculi during general and laparoscopic surgical procedures.
Device Story
Inzii Ripstop Redeployable Retrieval System is a single-use, sterile surgical instrument for tissue specimen containment and extraction. Device comprises a flexible Ripstop nylon specimen bag and an introducer tube. Unlike the predicate, the bag is supplied in a deployed state and must be retracted into the tube before insertion through a trocar. Once inside the body cavity, the mechanism deploys the bag; supports automatically open the bag for sample collection. The device allows for multiple redeployments within a single surgical procedure. For final extraction, the bag is cinched closed using a cord loop, detached from the deployment mechanism, and removed through the incision site. Used in general and laparoscopic surgery by surgeons. Benefits include improved bag strength and the ability to retrieve multiple specimens during one procedure.
Clinical Evidence

- Indications for use: Applied Medical's Inzii Ripstop Redeployable retrieval system is indicated for use as a receptacle for the collection and extraction of tissue, organs, and calculi during general and laparoscopic surgical procedures.
#### Comparison of Technological Characteristics with the Predicate Device
The subject device Inzii Ripstop Redeployable Retrieval System has the same indications for use as the predicate device Inzii Tissue Retrieval System. The subject device features a stronger Ripstop nylon bag and a change in design that allows it to be deployed multiple times.
The predicate device is packaged with the bag rolled up inside the tube. The predicate device is inserted into a trocar, the bag is deployed followed by the bag being cinched closed, the Introducer tube and trocar removed, and the bag with the specimen retrieved through the incision site.
The subject device is packaged with the bag outside of the bag must be retracted into the tube, followed by inserting it into the trocar and deployed to retrieve the specimen. If a surgeon deems it appropriate, the subject device can be redeployed multiple times in a single surgical procedure. For final deployment, the bag is cinched closed, the Introducer tube and trocar are removed, and the bag with the specimen is retrieved through the incision site. Table 1 below provide a side-by-side comparison of the predicate and subject device's attributes.

Table 1: Substantial Equivalency Comparison
{7}------------------------------------------------
#### Discussion of Performance Data
Performance testing included non-clinical bench tests and simulated use tests where the subject and predicate devices were tested side by side to demonstrate substantial equivalence. In addition to the tests covered per K060051, the strength of the Ripstop nylon bag was also demonstrated using an additional test performed in K100959, thus adding the model in scope of K100959, CD003 5mm Inzii Universal Retrieval System as a reference device. Applied Medical submits a predicate device and reference device to demonstrate substantial equivalence of the subject device.
{8}------------------------------------------------
# K232880
The performance data includes a summary of test methods, sample size, acceptance criteria, and results. The following performance data were provided in support of the substantial equivalence determination.
- Specimen Retrieval System Functionality testing ●
- Specimen Retrieval System Leak testing ●
- Specimen Bag Closure testing ●
- Specimen Bag Tear Resistance Test ●
- Specimen Bag Strength testing

- Limited Contact Duration
Based on the nature and duration of the device contact, the following biological endpoints were considered:
- Cytotoxicity ●
- Sensitization
- Intracutaneous Irritation ●
- Acute Systemic Toxicity (AST) ●
- Material Mediated Pyrogenicity (MMP) .
## Conclusion
Based on the intended use, technological characteristics, and performance testing results, the subject device is considered substantially equivalent to the predicate device.
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.
