The provided FDA 510(k) summary describes several sterilization and washer-disinfector systems. The acceptance criteria and testing detailed are for modifications related to component obsolescence (oscillator replacement, coin cell battery to super capacitor, flash memory component alternates and associated software updates). The document does not describe a study related to AI or human-in-the-loop performance. Therefore, questions related to expert consensus, MRMC studies, effect size, and standalone algorithm performance are not applicable.

Here's an analysis of the acceptance criteria and supporting studies for the component modifications across the various devices:

1. Table of Acceptance Criteria and Reported Device Performance

Across all devices (AMSCO 600 Steam Sterilizer, V-PRO maX 2, V-PRO s2, V-PRO 60 Low Temperature Sterilization Systems, and RAS Racks/Cycle), the acceptance criteria and performance for the specific modifications are consistent:

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the specific sample sizes (e.g., number of cycles, number of biological indicators) used for these non-clinical performance tests. It refers to "worst-case load" for the sterility assurance tests.

The provenance of the data is non-clinical performance testing conducted by the manufacturer, STERIS Corporation. The country of origin is implicitly the United States, given STERIS's address in Mentor, Ohio, and the FDA submission. The studies are retrospective in the sense that they are proving the modified device performs equivalently to the original validated design.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This question is not applicable as the studies described are non-clinical performance tests verifying device functionality and sterility/cleaning efficacy, not diagnostic or interpretive tasks requiring human expert ground truth. The "ground truth" for these tests is defined by established sterilization and cleaning standards (e.g., "no growth" for biological indicators, confirmed cleaning efficiency).

4. Adjudication Method for the Test Set

This question is not applicable for non-clinical performance tests. The results (e.g., growth/no growth, successful software operation) are typically objective and determined by laboratory analysis or automated system checks.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. The document explicitly states that the modifications "has no impact on the device performance" compared to the predicate device because the changes are related to component obsolescence, not a change in the fundamental operating principle or intended use that would require a comparison of human reader effectiveness.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done

This question is not applicable. The devices are sterilization and cleaning equipment, not algorithms that perform diagnostic or interpretive functions. The software tests performed are focused on verifying the proper functioning of the embedded system software controlling the sterilizers/washer-disinfectors, not standalone interpretive performance.

7. The Type of Ground Truth Used

The ground truth used for these non-clinical tests is based on:

• Biological indicator results: "No growth" post-sterilization, indicating successful killing of microorganisms. This is a direct measure of sterility.
• Physical and chemical parameters verification: Ensuring cycle data (time, temperature, pressure, sterilant injection weight) for sterilizers and cleaning/thermal disinfection parameters for the washer-disinfector (temperature, time, chemical dosing, pump pressure) meet pre-defined specifications.
• Software functionality: Verification that the embedded software correctly sets and reads Real-Time Clock (RTC), loads and runs applications, and ensures proper operation using serial flash memory.
• Cleaning efficiency: For the RAS Racks/Cycle, comparison of cycle data between modified and original controllers to confirm equivalent cleaning efficiency.

These "ground truths" are derived from validated operational parameters and expected biological/physical outcomes inherent to sterilization and cleaning processes, as per industry standards and internal validation protocols.

8. The Sample Size for the Training Set

This question is not applicable. These are hardware/software modifications to existing medical devices, not AI/ML algorithms that require a separate training set. The "associated software updates" are to accommodate new hardware components (flash memory, super capacitor) and ensure the existing validated sterilization/cleaning cycles continue to operate as intended.

9. How the Ground Truth for the Training Set Was Established

This question is not applicable, as there is no "training set" in the context of these device modifications.

The V-PRO s2 Low Temperature Sterilization System is a new vaporized hydrogen peroxide sterilizer model to be added to the STERIS V-PRO family of sterilizers. The V-PRO product line currently consists of the V-PRO 1, V-PRO 1 Plus, V-PRO maX, V-PRO maX 2 and V-PRO 60 Sterilizers.

The V-PRO s2 Sterilizer contains the same three sterilization cycles as the predicate device (K172319), the Lumen, Non Lumen and Flexible Cycles, with a new cycle, the Fast Cycle. In addition, compared to the claimed predicate device, the proposed device contains a cabinetry modification, adds additional claims for devices that may be processed in the Flexible Cycle, and increases the maximum claimed load weight for the Non Lumen Cycle.

The V-PRO 60 Low Temperature Sterilization System is a vaporized hydrogen peroxide sterilizer model that currently exists in the STERIS V-PRO family of sterilizers. The current proposed device claims are intended to modify the indications for use statement.

As with the predicate device (K172319), the V-PRO 60 Sterilizer has three preprogrammed cycles: the Lumen Cycle, the Non Lumen Cycle and the Flexible Cycle, none of which are being altered. The V-PRO 60 Low Temperature Sterilization System is intended for terminal sterilization of cleaned, rinsed, dried and packaged surgical instruments used in healthcare facilities.

The V-PRO s2 and V-PRO 60 Low Temperature Sterilization Systems are intended for terminal sterilization of cleaned, rinsed, dried and packaged surgical instruments used in healthcare facilities and utilizes VAPROX® HC Sterilant to sterilize the intended devices through exposure to vaporized hydrogen peroxide (VHP). The pre-programmed cycles all utilize a conditioning phase, a sterilize phase and an aeration phase. 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.

The provided text is a 510(k) Premarket Notification from the FDA, detailing the substantial equivalence of the STERIS V-PRO s2 Low Temperature Sterilization System and modifications to the V-PRO 60 Low Temperature Sterilization System to a legally marketed predicate device. This document describes the acceptance criteria and the study that proves a medical device (sterilizer) meets these criteria, rather than an AI/ML powered device.

Therefore, the requested information points related to AI/ML device studies (sample size for test/training sets, data provenance, number of experts, adjudication methods, MRMC studies, standalone performance, type of ground truth, etc.) do not apply to this document as it pertains to a physical sterilization device and not a diagnostic AI/ML system.

However, I can extract the acceptance criteria for the sterilization device and the reported performance based on the provided text.

Acceptance Criteria and Reported Device Performance (for a Sterilization Device)

The "acceptance criteria" for a sterilizer device are typically demonstrated through various validation studies to ensure the device effectively sterilizes medical instruments. The "reported device performance" is the conclusion that these studies meet the established criteria.

Here's a table based on the "Summary of Nonclinical Tests" section (Page 17-18) which outlines the tests conducted (functioning as acceptance criteria) and their successful results (reported performance):

1. Table of Acceptance Criteria and Reported Device Performance

Regarding the AI/ML-specific questions, as stated previously, this document does not contain information on an AI/ML powered device. Therefore, the following points are not applicable:

2. Sample size used for the test set and the data provenance: Not applicable. The document discusses "validation studies" and "validation loads" for a sterilizer, which are physical materials and instruments, not data samples for an AI test set.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for a sterilizer is established through scientific validation (e.g., microbial kill, chemical indicators), not human expert review.
4. Adjudication method for the test set: Not applicable.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
7. The type of ground truth used: For a sterilizer, the ground truth is the demonstrable absence of viable microorganisms ("sterility") and material compatibility, established through laboratory methods (e.g., biological indicators, chemical indicators, and material analysis) under worst-case conditions, as opposed to expert consensus, pathology, or outcomes data in the context of diagnostic AI.
8. The sample size for the training set: Not applicable. This refers to a physical device, not an AI model.
9. How the ground truth for the training set was established: Not applicable.

The provided text describes the acceptance criteria and supporting studies for the STERIS Amsco V-PRO Low Temperature Sterilization Systems.

Here's the breakdown:

1. A table of acceptance criteria and the reported device performance

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

The document primarily describes validation studies for the V-PRO sterilization systems, which are typically performed in a prospective manner.

• Determination of Worst Case Material for VHP: This refers to previous submissions, but the current document specifically highlights Kraton as the "most resistant material." No specific sample size is given for how many materials were evaluated to determine Kraton as the worst case in previous studies.
• Medical Device Material Compatibility: "20 materials" were tested.
• Cytotoxicity Evaluation of Medical Devices: "various medical devices containing [unspecified material components]" were tested.
• Hydrogen Peroxide Residual Analysis of Processed Medical Devices: "19 proposed compatible materials" were tested across "three (3), worst case, back-to-back Lumen Cycles" in the V-PRO 60 Sterilizer.

The provenance of the data (country of origin) is not explicitly stated, but as this is an FDA submission for a U.S. company (STERIS Corporation, Mentor, OH), it's highly probable the studies were conducted in the U.S. or at facilities compliant with U.S. regulatory standards.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

This type of information is not applicable to the studies described. The studies are engineering and chemical validation tests for a sterilization system, not diagnostic device studies that would require expert human review or interpretation of medical images or patient data to establish ground truth.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

This information is not applicable as the studies are not diagnostic assessments requiring adjudication of human reader interpretations. The acceptance criteria are based on measurable physical and chemical properties and biological effects (sterilization efficacy, material integrity, cytotoxicity, residuals).

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

This is not applicable. The device is a sterilization system, not an AI-powered diagnostic tool used by human readers. Therefore, no MRMC study or AI assistance improvement metrics are relevant.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This is not applicable. The device is a sterilization system and there is no algorithm or AI component involved in its operation or performance evaluation.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" in these validation studies is established by objective scientific and engineering measurements and standards:

• Sterilization effectiveness: Implicit in the "Worst Case Material" determination, where the goal is sterilization. Sterilization is typically confirmed by biological indicators demonstrating the inactivation of a specific resistant microorganism (e.g., Geobacillus stearothermophilus) to a defined sterility assurance level (SAL). While not explicitly detailed here, this is a standard method for sterilization validation.
• Material compatibility: Visual inspection for defects (crazing, cracks, chipping) and functional testing of devices after processing.
• Cytotoxicity: In vitro assays to assess cellular toxicity, with controls to ensure assay validity.
• Hydrogen peroxide residual analysis: Chemical analytical methods to quantify residual hydrogen peroxide, compared against established biological tolerance limits for mucosal and internal tissue contact.

8. The sample size for the training set

This is not applicable. The device is a sterilization system, not a machine learning model. There is no concept of a "training set."

9. How the ground truth for the training set was established

The Sterilizers use VAPROX® HC Sterilant to sterilize the intended devices through exposure to vaporized hydrogen peroxide (VHP). 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.

The V-PRO 1, V-PRO 1 Plus and V-PRO maX Low Temperature Sterilization Systems are programmed to enact one (the Lumen Cycle), two (the Lumen Cycle and the Non Lumen Cycle) or three (the Lumen Cycle, the Non Lumen Cycle and the Flexible Cycle) cycles, respectively.

The STERIS V-PRO Low Temperature Sterilization Systems were studied to verify two modifications: the removal of eye-contacting limitations and the addition of polyurethane as a compatible material for the Lumen Cycle.

Here's a breakdown of the acceptance criteria and study details:

1. Acceptance Criteria and Reported Device Performance

2. Sample Sizes Used for the Test Set and Data Provenance

The document does not explicitly state the exact "sample size for the test set" in terms of number of unique devices or materials for each specific test. However, it indicates:

• For residual hydrogen peroxide and cytotoxicity comparison: "materials" were processed.
• For in-device cytotoxicity and tissue residue: "medical devices" were processed.
• For ocular irritation: "Materials coupons" were processed.
• For polyurethane compatibility: "polyurethane-containing device" and "polyurethane material" were evaluated.

Data Provenance: The studies were conducted by STERIS Corporation for a 510(k) premarket notification. This implies the data is prospective for the purpose of demonstrating the safety and effectiveness of the proposed changes. The country of origin of the data is not specified but is presumably the USA, where STERIS Corporation is based.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

This information is not provided in the document. The tests described are primarily laboratory-based evaluations of chemical residues, cytotoxicity, material compatibility, and biological irritation, rather than assessments requiring interpretation by clinical experts. For biocompatibility tests like ocular irritation per ISO 10993-10, trained toxicologists or evaluators would interpret the results.

4. Adjudication Method for the Test Set

This information is not applicable as the studies described are laboratory-based experimental validations, not clinical studies requiring independent interpretation or adjudication of outcomes by multiple experts.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

A MRMC comparative effectiveness study was not done. This type of study is typically performed to evaluate the diagnostic accuracy of imaging or other interpretive devices, often with and without AI assistance to human readers. The STERIS V-PRO System is a sterilizer, and its performance is evaluated through physical, chemical, and biological efficacy studies, not reader interpretation.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

A standalone study was not done because the device itself is a sterilizer, not an algorithm. Its performance is inherent in its operation (sterilization efficacy, material compatibility, residue levels), not in an algorithmic output.

7. Type of Ground Truth Used

The ground truth used in these studies is based on:

• Quantitative measurements: Residual hydrogen peroxide levels (chemical analysis).
• Biological assays: Cytotoxicity tests (e.g., using live cells to detect toxic effects), ocular irritation tests (per ISO 10993-10 guidelines, likely involving animal models or in vitro alternatives).
• Visual assessment: Material degradation or cosmetic changes.
• Sterilization efficacy: Implied to be based on inactivation of biological indicators with a known sterility assurance level (SAL).

8. Sample Size for the Training Set

This information is not applicable as the V-PRO Sterilization System is a physical device, not an AI/ML algorithm that requires a training set.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable as there is no training set for this device type.

The V-PRO 60 Sterilizer uses VAPROX® HC Sterilant to sterilize the intended devices through exposure to vaporized hydrogen peroxide (VHP). Its three preprogrammed cycles all utilize a conditioning phase, a sterilize phase and an aeration phase. 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.

This document describes the V-PRO® 60 Low Temperature Sterilization System, a vaporized hydrogen peroxide sterilizer. The acceptance criteria are based on achieving sterility and maintaining material compatibility.

1. Table of Acceptance Criteria and Reported Device Performance

Study Proving Device Meets Acceptance Criteria:

The document summarizes the "Summary of Nonclinical Tests" performed on the V-PRO 60 Low Temperature Sterilization System to demonstrate its substantial equivalence to the predicate device, the V-PRO maX Low Temperature Sterilization System. The studies aim to prove the device's ability to sterilize various medical devices effectively and safely.

2. Sample Size Used for the Test Set and Data Provenance:

The document provides specific sample sizes for particular tests:

• AOAC Sporicidal Test: "All 720 carriers processed using 3 lots of EOSL sterilant."
• Validation Loads:
  • Lumen Cycle: "a maximum of twelve (12) lumens per load... consisting of one instrument tray with instrument organizers and mat and two pouches for a total weight of 11 lbs (5.0 kg)."
  • Non Lumen Cycle: "a validation load consisting of one instrument tray with instrument organizers and mat and one pouch for a total weight of 12 lbs (5.4 kg)."
  • Flexible Cycle: "one flexible endoscope, packaged into a tray with silicone mat, instrument organizers and light cord (if not integral to scope) and no additional load."
• Biocompatibility and Material Compatibility: "23 materials" were analyzed.

Data Provenance: The document does not explicitly state the country of origin or whether the data is retrospective or prospective. However, based on the nature of medical device clearance submissions to the FDA (United States Food and Drug Administration), these are typically prospective laboratory and simulated-use studies conducted by the manufacturer or authorized testing facilities, aiming to meet regulatory requirements prior to market entry.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:

The document does not specify the "number of experts" or their "qualifications" used to establish ground truth. The studies involve standardized microbiological and engineering tests rather than expert interpretation of results in a clinical setting. For sterilization studies, the ground truth is typically established by laboratory methods such as growth/no growth of biological indicators (e.g., Geobacillus stearothermophilus) following exposure to the sterilization process.

4. Adjudication Method for the Test Set:

Not applicable. The tests described are objective performance evaluations (e.g., sterility, log reduction, material compatibility) rather than interpretation-based assessments that would require an adjudication method like 2+1 or 3+1.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done:

No, an MRMC comparative effectiveness study was not done. The device is a sterilizer, and its performance is evaluated through objective physical and biological tests, not through human reader interpretation of cases.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:

Yes, the studies described are standalone performance evaluations of the sterilization device. There is no "human-in-the-loop" interaction in the output or interpretation of the sterilization cycle results beyond operating the device and reading standard indicators. The device itself is the "algorithm only" in the context of its function.

7. The Type of Ground Truth Used:

The primary type of ground truth used would be:

• Microbiological Negativity/Positivity: For sterilization efficacy tests (AOAC Sporicidal, D-value/Total Kill, ½ Cycle Modified Total Kill Endpoint, ½ Cycle Sterilization Verification, Simulated Use, In Use), the ground truth is established by culturing biological indicators or test organisms and observing the presence or absence of growth. "Sterile" or "no growth" is the ground truth for effective sterilization.
• Physical/Chemical Analysis: For biocompatibility and material compatibility, the ground truth is established through laboratory analyses (e.g., cytotoxicity assays, residue analysis, visual inspection for degradation) and quantitative measurements.
• Process Parameter Verification: For Final Process Qualification, the ground truth is established by objective measurements of process parameters (time, temperature, pressure, sterilant injection weight) and the observed color change of chemical indicators.

8. The Sample Size for the Training Set:

Not applicable. This is a physical device (sterilizer) and not an AI/machine learning model that would require a 'training set' of data in the conventional sense. The development of the sterilizer's cycles and parameters is based on engineering principles and iterative testing, not on data training in the way an algorithm learns from a dataset.

9. How the Ground Truth for the Training Set Was Established:

Not applicable, as there is no "training set" in the context of an AI/machine learning algorithm for this device. The physical and biological principles governing sterilization, along with extensive engineering development and testing, define the performance of the sterilizer.
