The V-PRO 1 Plus and V-PRO maX Low Temperature Sterilization Systems, with VAPROX® HC Sterilant, are vaporized hydrogen peroxide sterilizers intended for use in the terminal sterilization of cleaned, rinsed and dried metal and nonmetal medical devices used in healthcare facilities. The pre-programmed sterilization cycles (Lumen Cycle, Non Lumen Cycle, and Flexible Cycle) operate at low pressure and are thus suitable for processing medical devices sensitive to heat and moisture.
Device Story
V-PRO 1 Plus and V-PRO maX are vaporized hydrogen peroxide (VHP) sterilizers for heat/moisture-sensitive medical devices. Devices are placed in a chamber; user selects pre-programmed cycle (Lumen, Non Lumen, or Flexible) via GUI. System uses VAPROX HC Sterilant (59% hydrogen peroxide). Process involves conditioning (chamber prep), sterilization (VHP exposure at low pressure), and aeration (residual removal). No post-cycle cool-down required. Used in healthcare facilities by trained staff. Output is sterilized, ready-to-use medical equipment. Benefits include rapid, low-temperature terminal sterilization of complex instruments, including those with diffusion-restricted areas or specific lumen geometries.
Clinical Evidence
Bench testing only. Validation included modified total kill endpoint verification, sterilization verification of cycle claims, simulated use testing, and final process qualification. Performance confirmed using biological indicators (SCBI) and chemical indicators under worst-case conditions (e.g., 50 lb load for Non Lumen Cycle).
Technological Characteristics
Vaporized hydrogen peroxide (VHP) sterilizer. Chamber: 136 L welded aluminum. V-PRO 1 Plus: stainless steel side panels; V-PRO maX: plastic side panels. Process parameters: time, chamber/vaporizer temperature, pressure, sterilant injection weight. Connectivity: onboard printer. Sterilant: VAPROX HC (59% H2O2).
Indications for Use
Indicated for terminal sterilization of cleaned, rinsed, and dried metal and nonmetal medical devices in healthcare facilities. Includes lumened/non-lumened instruments, rigid/semi-rigid/flexible endoscopes, and devices with diffusion-restricted spaces (e.g., hinged forceps/scissors). Specific lumen configurations (ID/length) and load weights (up to 50 lbs for Non Lumen Cycle) are defined for Lumen, Non Lumen, and Flexible cycles.

## K160433/ S001 STERIS Response to Request for Additional Information V-PRO® 1 Plus and V-PRO® maX Low Temperature Sterilization Systems
The proposed devices have an intended use similar to the predicates with the same technological characteristics. Although, the indications differ slightly, the provided performance data demonstrate equivalence. Therefore, the proposed V-PRO 1 Plus and V-PRO maX Low Temperature Sterilization Systems are substantially equivalent to the predicate devices, the V-PRO 1 Plus and V-PRO maX Low Temperature Sterilization Systems.
#### 3. Description of Device
The V-PRO 1 Plus and V-PRO maX Sterilizers use VAPROX® HC Sterilant to sterilize the intended devices through exposure to vaporized hydrogen peroxide (VHP). Devices that meet the criteria described within the indications for use and composed of compatible materials are placed within the sterilization chamber and the appropriate cycle selected through the graphic user interface. The preprogrammed cycles all utilize a conditioning phase which prepares the chamber, a sterilize phase in which loaded devices are exposed to the sterilizing agent, VHP, at low pressure and an aeration phase to remove residual hydrogen peroxide. The packaged sterilized devices are ready for use at the completion of the cycle, no cool down or aeration period is required following completion of the cycle.
{9}------------------------------------------------
The V-PRO 1 Plus Low Temperature Sterilization System provides two cycle options, Lumen and Non Lumen. The sterilizer contains a 136 L welded aluminum chamber with two shelves for device loading, an onboard printer to provide cycle printouts, a cup interface where the VAPROX HC cups are loaded, a display for the graphic user interface and the components necessary to achieve the desired cvcle parameters (injection cylinder, vaporizer, vacuum pump and catalytic converter). The side panels of the sterilizer are composed of stainless steel.
The V-PRO maX Low Temperature Sterilization System provides three cycle options, Lumen, Non Lumen and Flexible. The sterilizer contains a 136 L welded aluminum chamber with two shelves for device loading, an onboard printer to provide cycle printouts, a cup interface where the VAPROX HC cups are loaded, a display for the graphic user interface and the components necessary to achieve the desired cycle parameters (injection cylinder, vacuum pump and catalytic converter). The side panels of the sterilizer are composed of plastic.
The purpose of this pre-market notification is to modify the maximum load weight for the Non Lumen Cycle from 19.65 to 50 lbs, to add titanium diffusion-restricted areas to the indications for use of the Non Lumen Cycle, and to remove the term "reusable" from indications for use statement.
#### 4. Intended Use

The results of the V-PRO 1 Plus and V-PRO maX Low Temperature Sterilization Systems' Non Lumen Cycle verification studies demonstrate that the sterilizers perform as intended. Based on the intended uses, technological characteristics and non-clinical performance data, the subject devices (V-PRO 1 Plus and V-PRO maX) are as safe, as effective and perform at least as safely and effectively as the legally marketed predicate device (K131120), Class II (21 CFR 880.6860), product code MLR.
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.
