#### Device Description
Olympus Respiratory America (ORA) dba Spiration, Inc. is submitting this Traditional 510(k) premarket notification to add a modified name and modified Indication for use to for the already cleared Olympus B7-2C Balloon Catheter (K962901, August 20, 1996). The current cleared Indication for Use for the B7-2C Balloon Catheter is as follows (the 510(k) was submitted with 2 model #'s with identical indications):
Olympus B5-2C/B7-2C Balloon Catheters are to be used for selective endoscopic bronchography, medicine injection to bronchi, saline injection
{4}------------------------------------------------
associated with bronchoalveolar lavage, foreign body removal from bronchi and bronchial hemostasis.
The device design and materials are completely unchanged. it will be provided packaged and sterilized to ORA, and we will private label it. The only difference will be the package labeling and Instructions for Use indicating that the device is the B7-2C Occlusion Balloon, and the modified Indication for Use.
In the modified indication for use, the B7-2C Occlusion Balloon will also be available for localizing air leaks.
We proposed the following modified indication:
The B7-2C Occlusion Balloons is to be used for selective endoscopic bronchography. saline injection associated with bronchoalveolar lavage, bronchial hemostasis and airway occlusion to localize air leaks.
The proposed modified Indication for Use removes medicine injection to bronchi, foreign body removal from bronchi and adds airway occlusion to localize air leaks.
Both the predicate and proposed device, which is identical, are an accessory to Olympus bronchoscopes. Spiration will be private labeling the device with a modified name and Indications for use, which fall within the current Intended Use.
The device is introduced through the instrument channel of the bronchoscope. The device is constructed of the inflatable balloon, catheter, bifurcation, irrigation port, air feed cap and stopcock. The B7-2C device is 1050 mm in working length, with a pre-inflation diameter of 2.55 mm and a post-inflation diameter of 13 mm, with a max volume of 1.7 cc.
## Device Materials (Patient Contacting)
The B7-2C Occlusion Balloon is manufactured with materials commonly used in medical device applications. The patient contacting materials are included in Table 5-1 below:
#### Table 5-1 B7-2C Patient Contacting Materials

{6}------------------------------------------------
The intended use of the subject device is virtually identical to that of the predicate device with respect to bronchial hemostasis. Whereas the predicate device uses pressure aqainst the airway walls to support hemostasis, the proposed device uses pressure against the airway to localize air leaks within the lung.
#### Performance Data
Performance testing has been completed on both the predicate device as well as the subject device, which is identical to the subject device. The B7-2C Occlusion Balloon was subjected to the following verification and validation tests, as applicable:
#### Biocompatibility
Repeat biocompatibility testing was conducted on the subject device to confirm that it meets current biocompatibility requirements. The tests included cytotoxity, intracutaneous irritation, materials mediated pyrogen, sensitization and systemic toxicity. All tests were successfully passed.
#### Sterilization/Shelf-Life
The device was validated to achieve a sterility assurance level of 10°.
#### Performance Testing
Testing was completed for the subject device to evaluate the ability of the B7-2C to successfully occlude airways. All tests (N=30) showed complete occlusion of the airway. Based on the statistical plan, this shows that the B7-2C balloon is capable of occluding airways at 90% conformance and 95% confidence. All acceptance criteria defined in the protocol was met.
Verification and burst testing bench was completed on the predicate device to confirm that the performance of the device conforms to mechanical and functional specifications. The testing included:
- Verification ●
- . Burst testing
## Conclusion (Statement of Equivalence)
As confirmed in the prior 510(k) for the predicate device, which is identical to the subject device, the device successfully passed all performance testing. For the subject device, biocompatibility testing was successfully passed, as well as bench testing to verify the ability of the device to successfully occlude airways.
As stated above, the intended use of the subject device is virtually identical to that of the predicate device with respect to bronchial hemostasis. Whereas the predicate device uses pressure against the airway walls to support hemostasis, the proposed device uses pressure against the airway to allow the physician to localize air leaks within the lung.
Since the modified device name and Indication for Use are the only changes, and the proposed Indication for Use is within the original Intended Use, we believe that the information provided supports a determination of substantial equivalence to the predicate device, and market clearance of the B7-2C Occlusion Balloon.

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.
