A chemical indicator for monitoring all cycles within the STERIS® V-PRO™ 60 (Flexible, Lumen & Non-lumen). The VH2O2 Indicators are intended to be used by health care providers with sterilization wraps, containers, cassettes, or pouches to distinguish between processed and unprocessed units. Colors other than blue such as yellow/green should be treated as a process failure.
Device Story
SPSmedical VH2O2 External Indicators are single-use chemical process indicators (labels and cards) used to verify exposure to vaporized hydrogen peroxide in sterilization cycles. The device consists of a synthetic substrate printed with a nontoxic chemical indicator ink. During the sterilization process, the indicator undergoes a visual color change from pink to blue upon exposure to hydrogen peroxide. Healthcare providers use these indicators to distinguish between processed and unprocessed items in clinical settings. The device provides a qualitative visual signal; failure to reach the blue color (e.g., remaining yellow/green) indicates a process failure. The device is used by healthcare staff to ensure items have been subjected to the sterilization cycle, thereby supporting sterile processing workflows and patient safety.
Clinical Evidence
Bench testing only. Simulated use testing was performed in triplicate in lumen and flexible cycles of the STERIS V-PRO 60 sterilizer using three lots of product at or beyond their 24-month shelf life. Testing verified the indicators turned blue in a half-cycle with end-of-shelf-life sterilant in a fully loaded chamber. Post-processing color stability was verified for six months.
Technological Characteristics
Chemical indicator ink on synthetic paper/label stock (e.g., Tyvek, polypropylene, polystyrene). Visual color change (pink to blue) upon exposure to vaporized hydrogen peroxide. Meets ANSI/AAMI/ISO 11140-1 performance requirements for process indicators. Shelf life: 2 years. Storage: 15-30°C, protected from light, acids, and alkaline chemicals.
Indications for Use
Indicated for health care providers to monitor vaporized hydrogen peroxide sterilization cycles (Flexible, Lumen, Non-lumen) in the STERIS V-PRO 60 sterilizer. Used with sterilization wraps, containers, cassettes, or pouches to distinguish processed from unprocessed items.

## PREDICATE DEVICE:
SPSmedical VH2O2 Indicators K140566.
## DEVICE DESCRIPTION:
The SPSmedical VH2O2 External Indicators are single use process indicators, intended for use in verifying exposure to all vaporized hydrogen peroxide cycles in the STERRAD® 100S, 200, 100NX, NX, STERIS® V-PRO® 1, V-PRO® 1 Plus, V-PRO® maX and Sterilucent™ PSD-85 sterilizers. For purposes of this submission testing has been performed to validate the SPSmedical VH2O2 External Indicators for use in the Steris® V-PRO® 60 sterilizer.
Indicators will identify if an item has seen vaporized hydrogen peroxide during the Steris® V-PRO® 60 sterilization processes by changing from a pink to a blue signal color. They provide a visual indication to help distinguish between processed and unprocessed items.
Physical Properties: The SPSmedical VH2O2 External Indicators consist of two (2) devices, an indicator label and an indicator card. These devices have minor physical differences. The label has an adhesive backing while the card does not. They use the same manufacturing process and are printed on the same substrate.
Technical Characteristics: The chemical indicator ink utilized on the SPSmedical VH2O2 External Indicators has been formulated to meet the performance requirements ANSVAAMI/ISO 11140-1 for Process Indicators.
Functional Characteristics: The SPSmedical VH2O2 External Indicators are designed to monitor sterilization cycles in low temperature vaporized hydrogen peroxide sterilizers. They are a reliable tool used for the monitoring of vaporized hydrogen peroxide sterilization processes and provide a visual indication that hydrogen peroxide (H2O2), an essential ingredient in the vaporized hydrogen peroxide sterilization process has been introduced into the sterilizer's chamber. Indicators will identify if an item has seen H2O2 during the sterilization process. Indicators change from an initial color of pink to a final signal color of blue.
## INTENDED USE:
The SPSmedical VH3O2 External Indicators are intended to be used by health care providers with articles such as sterilization wraps, containers, cassettes, or pouches to distinguish between processed and unprocessed items. Indicators change to a signal color of blue after exposure to vapor hydrogen peroxide.
{4}------------------------------------------------
#### BIOCOMPATIBILITY
SPSmedical VH2O2 External Indicators are manufactured using nontoxic inks and substrates that will not alter the chemical composition of the products being sterilized and are safe for human contact. SPSmedical VH2O2 External Indicators can be disposed in general waste receptacles.
#### STORAGE CONDITIONS:
Store the SPSmedical VH2O2 External Indicators in a cool, dry place (15-30°C), and away from any alkaline chemicals, acids and sources of light.
#### NON-CLINICAL TESTING:
Since the SPSmedical VH2O2 External Indicators are a legally market device only the new Steris® V-PRO® 60 sterilization cycles were validated for use through simulated use testing. Three (3) lots of product were used which were all at or beyond their real time shelf life expiration of twenty four (24) months.
Simulated Use Testing: Consisted of verifying SPSmedical VH2O2 External Indicators turned blue in a half cycle with end of shelf life sterilant with a fully loaded chamber at Steris® by Steris® technicians. All testing was performed in triplicate in lumen and flexible cycles of the Steris® V-PRO® 60 sterilizer.
Shelf Life: When properly stored the SPSmedical VH2O2 External Indicators maintain a shelf life of up to two (2) years from the date of manufacture. The expiration date is located on every pack. Post processing indicator stability has been verified to maintain color change results for a minimum of six (6) months when properly stored.
All other concerns with the SPSmedical VH2O2 External Indicators have been previously validated. There have been no changes to the product since the predicate filing under K140566.
#### COMPONENTS:
Indicators are composed of commercially existing materials of synthetic paper or label stock (e.g. Tyvek ", polypropylene, polystyrene etc ... ). The indicator ink is a nontoxic sterilization indicator ink that changes from an initial color of pink to a blue signal color when exposed to the stated vaporized hydrogen peroxide sterilization process described within this submission.
#### SUBSTANTIAL EQUIVALENCE DISCUSSION:
The predicate and subject devices are the exact same device. The predicate and subject devices are substantially equivalent in terms of their intended use, functional and technical characteristics within the vaporized hydrogen peroxide sterilization processes described within this submission.

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.
