## Predicate Device
Medtronic Endo-scrub 2:
K982594
## Product Description
The InstaClear Lens Cleaner system is equivalent to the predicate device cleared under K982594. The system includes a reusable AC powered console with pump, a reusable footpedal, and sterile disposable single-use accessories.
The system is used to clear the end of a rigid endoscope in order to maintain clear visualization of endoscopic procedures without having to remove the scope from the surgical site. The device is indicated for use during routine diagnostic procedures and during endoscopic sinus surgery (ESS).
The system accessories include sterile sheaths to fit various sizes of 4mm Olympus and Storz endoscopes, a sterile irrigation tubeset, and a non-sterile footpedal. The console includes software to control irrigation delivery and suction.
When performing ESS the scope is inserted into the nasal passages to visualize the sinuses. During the resection of tissue the scope lens is frequently covered in debris. such as blood and mucous that limits visualization. Traditionally the surgeon has to remove the scope, clean the lens, return the scope, and resume surgery. The proposed device is intended to attach directly to the endoscope shaft and provide fluid and suction to clean the lens of unwanted debris. This provides the surgeon with better images without debris and less instrument exchanges.
## Technological Characteristics
The system is used in the same way as the predicate system (K982594). The disposable sheath is placed on the shaft of an endoscope and directs fluid to the lens of the scope for the purpose of cleaning the lens of debris. Fluid delivery is actuated by a simple footpedal. Other than the footpedal and the console there are no other capital requirements. Fluid is pressurized using a pump on the console. The flow rate may be controlled by an adjustable knob on the back of the console. Connections to the console are limited to loading the tubeset through the pump, and connecting the footpedal.
# Material
The system uses the same patient-contacting materials that are utilized in predicate devices, as well as other legally marketed devices manufactured by Gyrus ACMI.
The patient contacting items are classified in accordance with ISO 10993-1, as an external communicating. tissue/bone/dentin device for limited exposure (<24hrs.). ISO
{5}------------------------------------------------
10993-1 and FDA Blue Book memo #G95-1 guidelines recommend that these direct patient contact parts have supporting data for cytotoxicity, sensitization and irritation. Full GLP biocompatibility testing (Cytotoxicity, sensitization, and irritation) on similar devices containing all patient contacting materials is on file for other devices currently marketed by Gyrus ACMI.
## Intended Use / Indications
Intended to clear the end of a rigid rod endoscope in order to maintain clear visualization of endoscopic procedures without having to remove the scope from the surgical site.
The device is indicated for use during routine diagnostic procedures and during endoscopic sinus surgery.
## Compliance to Standards
The design of the system complies with the following standards:
IEC 60601-1, IEC 60601-1-2, IEC 60601-2-18 ISO 10993-1, 5, 7, 10, Biological Evaluation of Medical Devices ISO 14971, Risk Analysis ISO 15223-1:2012, Medical Devices - Symbols to be used ISO 11135:2014, Sterilization of Health Care Products, EO Validation ISO 11138: 2006, Sterilization of health care products: Biological Indicators ISO 11607-1:2006, Packaging for Terminally Sterilized Medical Devices ISO 11607-2:2006, Packaging for Terminally Sterilized Medical Devices ISO 11737-1:2006, Sterilization of Medical Devices - Microbiological Methods ISO 11737-2:2009, Sterilization of Medical Devices - Microbiological Methods
Risk analysis was carried out in accordance with established in-house acceptance criteria based on ISO 14971. The design verification tests were identified and performed as a result of risk analysis assessment.
## Electrical safety and electromagnetic compatibility (EMC)
Electrical safety and EMC testing were conducted on the device complies with the applicable clauses of IEC 60601-1, and the IEC 60601-1-2 standard for EMC.
{6}------------------------------------------------
#### Summary of Sterilization and Shelf Life Discussion
The system console and footpedal are provided non-sterile and are reusable. The console and footpedal are to be wiped down with cleaning / disinfecting wipes after use.
The sheaths and tubesets are provided sterile for single-use. They are sterilized with Ethylene Oxide, using a cycle validated in accordance with ISO 11135 to provide a sterility assurance level of 10-6.
The Shelf Life period for the disposable items was determined through an analysis of the shelf-life stability of the materials used in the design of the devices, as well as an analysis of the packaging materials and processes used with other Gyrus ACMI devices. Shelf-life studies are on file to support an initial one year shelf life.
#### Summary of Performance Testing
Performance tests were executed to ensure that the system functioned as intended and met design specifications. The following non-clinical and preclinical tests and usability studies were conducted:
#### Non-Clinical / Preclinical Performance
Evidence of safety and effectiveness was obtained from two primary areas:
- 1) non-clinical (electrical, mechanical, functional) performance testing
- 2) preclinical (bench) evaluations and testing
Non-clinical: Basic safety and performance testing was performed in accordance with IEC standards. In addition, verification and comparison bench studies were conducted to evaluate the mechanical and functional performance. Testing included: cleaning compatibility, noise levels, heat generation, tabletop stability, burst pressure, suction strength, hub strength, torque strength, leak testing, ship testing, and baseline performance testing.
Stability: Representative samples were subjected to accelerated aging to confirm that the disposable devices maintain functionality and continues to meet specifications over time. The results of the accelerated age testing demonstrate that the device will be stable for the stated shelf-life. In addition, real time age testing will confirm the results of the accelerated age testing. Representative samples were also subjected to environmental conditioning and ship testing.
Preclinical: Evidence obtained from preclinical bench studies demonstrate that the system performs substantially equivalent to the predicate device in relevant aspects associated with cleaning cycle time, cleaning performance, clearing performance, and
{7}------------------------------------------------
leak / drip occurrence rate. For simulated use and bench testing. the selected medium was a blood analog appropriate for testing.
Testing demonstrated that the device performs as well as or better than the predicate device.
No clinical testing was conducted. The use of the device type has been documented in published literature and indicates safe and effective use for the target procedures and expected patient populations.
## Substantial Equivalence
The system operates in a similar manner as the predicate device. The disposable tubeset and sheaths are similar to the predicate devices physically and in their methods of operation. The tubeset offers irrigation to the surgical site and suction away from the surgical site.
The system uses similar or same patient-contacting materials in similar quantities that are utilized in the predicate device, as well as other legally marketed devices manufactured by Gyrus ACMI.
#### Conclusion
The performance of the InstaClear system was compared against the known performance characteristics of the predicate device. Testing demonstrated that the performance requirements were met, and that the system exhibited comparable performance characteristics to the predicate.
In summary, the InstaClear Lens Cleaner is substantially equivalent to the predicate device and presents no new questions of safety or efficacy.

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.
