The Kitazato OPU Needles consisting of: - Kitazato OPU Needle with Connection Tube (model number Type2) - Kitazato OPU Reduced Needle (model number Type3) - Kitazato OPU Two-Stage Reduced Needle (model number Type4) are intended to obtain oocytes from ovarian follicles.
Device Story
Kitazato OPU Needles are single-use, sterile, ultrasound-guided transvaginal needles used to collect oocytes from ovarian follicles. The device consists of a 304 stainless steel needle, ABS hub, PVC connection tube, and silicone stopper. It connects to a vacuum pump for aspiration. The device is operated by a physician in a clinical setting. The needle tip enters the follicle under ultrasound guidance; vacuum pressure draws the oocyte through the needle and tube into a collection vessel. The device facilitates oocyte retrieval for assisted reproduction, directly impacting the success of subsequent fertilization procedures. Variations include straight (Type2), single-tapered (Type3), and double-tapered (Type4) designs to accommodate different clinical needs.
Clinical Evidence
Bench testing only. Testing included: Endotoxin levels (<20 EU/device); Mouse Embryo Assay (MEA) (≥80% blastocyst development at 96h); sterilization validation (ISO 11135, ISO 10993-7); package integrity (ASTM F929-15, ASTM F88/F88M-15); transport testing (ASTM D4169-09); shelf-life studies (3-year); aspiration pressure testing; and biocompatibility (ISO 10993-1, including cytotoxicity, sensitization, and intracutaneous reactivity). All tests met acceptance criteria.
Indicated for obtaining oocytes from ovarian follicles in patients undergoing assisted reproduction procedures.
Regulatory Classification
Identification
Assisted reproduction needles are devices used in in vitro fertilization (IVF), gamete intrafallopian transfer (GIFT), or other assisted reproduction procedures to obtain gametes from the body or introduce gametes, zygote(s), preembryo(s) and/or embryo(s) into the body. This generic type of device may include a single or double lumen needle and component parts, including needle guides, such as those used with ultrasound.

As noted in the tables above, there are many similarities between the subject and predicate devices (e.g., materials, designs, etc.); however, differences do exist. The differences in technology noted in the tables above, do not raise different questions of safety or effectiveness as compared to the predicate device.
### 9. Non-Clinical Performance Data
As part of demonstrating substantial equivalence to the following non-clinical performance tests were conducted. The Kitazato OPU Needles passed all of the testing in accordance with internal requirements and applicable standards to support substantial equivalence of the subject device:
- Endotoxin testing per ANSI/AAMI ST72-2011: <20 EU/device .
- Mouse Embryo Assay (MEA): 1-Cell mouse embryos were incubated in extracts of the subject device at 37°C in an atmosphere containing 5% CO₂. The percent of embryos developed to the expanded blastocyst stage at 96 hours were assessed in comparison with the control group. The acceptance criterion was 1-Cell MEA: ≥80% expanded to blastocyst at 96 hours.
- Sterilization validation per ISO 11135:2014 and ISO 10993-7:2008 ●
- Package integrity testing following real-time aging:
- o Dye penetration testing per ASTM F929-15
- o Seal strength testing per ASTM F88/F88M-15
- Transport testing per ASTM D4169-09
- Shelf-life studies (real-time aged devices) were conducted to ensure that the following product ● specifications were met to support a three-year shelf-life:
- O MEA
- O Endotoxin
- Tensile testing (needle to hub and tubing to hub) O
- O Bending elasticity of needle – Return to normal position after bending 8° from straight
- Folding strength of needle No fracture of needle when folded at a 5 mm curvature radius O to 90°
- o Device appearance (burrs, scratches, damage)
- Dimensional assessments O
- . Aspiration pressure testing - Testing involved aspirating water through needles at the recommended aspiration pressures included in device labeling to ensure that devices operated as intended (i.e., no signs of deformation, blockages or damage)
- Biocompatibility testing was conducted according to ISO 10993-1- 2009. Testing included cytotoxicity (ISO 10993-5:2009), intracutaneous reactivity (ISO 10993-10:2010), and sensitization (ISO 10993-10:2010). The test articles assessed provided acceptable results as no signs of cytotoxicity, sensitization or irritation reactions were noted in testing.

## 10. Conclusion
The results of the testing described above demonstrate that the Kitazato OPU Needles are as safe and effective as the predicate device and supports a determination of substantial equivalence.
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.
