Indications for Use
Operio is a portable device for use in a surgical operating room that produces a directed, non-turbulent flow of air to the surgical site during ophthalmic surgery and to the sterile instruments used during surgery. The air flow from the device is HEPA-filtered to reduce the presence of particulate matter to reduce the microorganisms to a level of < 5 CFU per m3 at the surgical site and instruments. The air flow is intended to be directed parallel to the surgical site and/or instruments within: 20" (50 cm) in width, 47" (120 cm) in length and 15" (40 cm) in height. Device effectiveness may not be reliably detectable at a distance of 47 inches (120 cm) from the air flow outlet, and effectiveness depreciates beyond this specified area.
Device Story
Operio is a mobile air-handling unit for surgical operating rooms; recirculates ambient air through HEPA filter to create directed, non-turbulent clean air zone. Device uses single-use sterile shield to direct airflow over surgical site and instruments; eliminates need for patient attachment. Operated by surgical staff; positioned via castors. Provides HEPA-filtered air (99.995% efficiency) to reduce particulate matter and microorganisms (< 5 CFU/m3) at surgical site. Output allows clinicians to maintain sterile field during ophthalmic procedures without physical contact with patient or obstruction of workspace. Benefits include reduced risk of surgical site contamination.
Clinical Evidence
Clinical testing conducted at a Swedish University Hospital during ophthalmic surgery (n=23 patients, 31 samples). Primary endpoints were CFU levels and particulate counts at the surgical site/instruments. Results showed mean CFU of 0.4 CFU/m3 and mean particulate count of 1.1 particles of 0.5 µm/f3. Performance demonstrated statistically significant reduction in contaminants, meeting safety and effectiveness criteria compared to predicate.
Indicated for use in surgical operating rooms during ophthalmic surgery to provide directed, non-turbulent HEPA-filtered air to the surgical site and sterile instruments to reduce airborne particulate and microorganisms.

### Device description
The air zone unit Operio is used in a surgical operating room for cleaning the air in a given area by re-circulating the ambient air and cleaning it from airborne particles. The air is filtered through a HEPA filter and the air is generated over the areas where the demands of clean air are especially high. The air zone unit Operio is equipped with a control panel for adjustments and for positioning of the unit.
The air zone unit Operio is a mobile unit that with the help of castors easily can be moved around the patient to an optimal position or, when needed, transported inside the hospital between wards. It is also equipped with an optional instrument tray.
By using a unique sterile shield as a protective barrier the air zone unit can be placed close to the OR table and deliver HEPA filtered air to the surgical site and instruments to reduce the presence of airborne particulate and microorganisms.
### Indications for use
Operio is a portable device for use in a surgical operating room that produces a directed, nonturbulent flow of air to the surgical site during ophthalmic surgery and to the sterile instruments used during surgery. The air flow from the device is HEPA-filtered to reduce the presence of particulate matter to reduce the microorganisms to a level of < 5 CFU per m3 at the surgical site and instruments.
The air flow is intended to be directed parallel to the surgical site and/or instruments within: 20" (50 cm) in width, 47" (120 cm) in length and 15" (40 cm) in height. Device effectiveness may not be reliably detectable at a distance of 47 inches (120 cm) from the air flow outlet, and effectiveness depreciates beyond this specified area.
Difference from predicate device:
The air zone unit Operio is suitable for ophthalmic surgery and sterile instruments used during surgery. It is possible to deliver the clean air without coming into contact with the patient or compromising the work space required by surgical staff. The clean air flow can also be used over instruments and the area of the air flow is bigger compared to the predicate device.
The difference in indications for use compared to the predicate device does not introduce any new hazards and test results can confirm that the subject device is as safe and as effective for use.
#### Summary of technological characteristics compared to predicate devices
The subject device Operio differs from the predicate device in that it doesn't use a sterile nozzle and device does not depend on attachment to the patient. The subject device requires a single use sterile shield which functions as an equipment cover as well as to direct the non-turbulent flow to the surgical site. The sterile shield is attached to the unit and is not in contact with the patient.
To eliminate contaminated particles entering the surgical site, HEPA filtration is used by both the predicate device and the subject device. The efficiency of HEPA filtration of the subject

### Summary of testing
The performance characteristics of the air zone unit Operio have been obtained through both a series of tests, clinical and non-clinical, and performance specifications. Particulate test and CFU test results clearly meet the criteria for achieving reduction of airborne contamination at the intended surgical site and over instruments. The efficiency of HEPA filtration has been tested and is found better than the predicate device.
In testing, the predicate demonstrated a level of particulate presence by 68,122 particles of 0.5 um/f³, while the subject device had a level of particulates by 1.1 particles of 0.5 µm/f3.
The predicate device demonstrated a reduction from 10.73 to 1.60 CFU's whereas the subject device demonstrated a reduction from 48.2 to 0.4 CFU in a clinical environment.
The following non-clinical tests has been conducted: Simulated use test, Particulate counting test, Colony Forming Units counting test, Air velocity test, Air leakage test, Smoke test and Turbulence tests to demonstrate air flow patterns.

The following standards have been used for performance testing:
- IEC/EN 60601-1:2006 Medical electrical equipment Part 1: General requirements ● for basic safety and essential performance
- IEC/EN 60601-1-2:2007 Medical electrical equipment - Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic disturbances - Requirements and tests
### Summary of clinical testing
Clinical tests have been carried out in surgical procedures such as Ophthalmology. Measurements where made near the surgical site and over the instruments where the results demonstrated a statistically significant reduction in CFU levels as well as particulates. The CFU value is based on 31 samples from 23 patients. The clinical tests have been carried out in a Swedish University Hospital. As a mean value, the subject device had a CFU counting of 0.4. For particulate counting, the subject device had a mean value of 1.1 particles of 0.5 um/f3.
Since both particulate counts and CFU level doesn't exceed the predicate device in a clinical environment it is concluded that substantial equivalence is achieved as clinical validation.
#### Conclusion
Based on a comparison of the performance characteristics, the tests performed, clinical and nonclinical, it is concluded that the subject device Operio is substantially equivalent to the predicate device and therefore is as safe and as effective.

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.
