The provided text describes a 510(k) premarket notification for the STERIS V-PRO maX 2 Low Temperature Sterilization System. It focuses on the substantial equivalence of the proposed device to a predicate device, specifically regarding the addition of a "Specialty Cycle."

Based on the provided information, the device is a sterilizer, and the "acceptance criteria" and "study proving the device meets the acceptance criteria" refer to the sterilization efficacy and the validation studies conducted to demonstrate that the new Specialty Cycle effectively sterilizes the specified materials/devices.

Here's the breakdown of the information requested, based on the provided document:

Acceptance Criteria and Reported Device Performance

The core acceptance criterion for a sterilizer is to demonstrate the elimination of viable microorganisms. This is typically shown through achieving sterility with a certain Sterility Assurance Level (SAL), often by processing inoculated Biological Indicators (BIs). The effectiveness is demonstrated through "½ Cycle (Sterilization) Efficacy" and "Final Process Qualification."

Table of Acceptance Criteria and Reported Device Performance (Inferred from the document's validation summary):

Additional Requested Information:

1. Sample sizes used for the test set and the data provenance:

• Test Set Sample Sizes:
  • Non Lumen Cycle: Validation load consisting of two instrument trays for a total weight of 50 lbs (22.7 kg).
  • Fast Non Lumen Cycle: Validation load consisting of one pouched instrument tray for a total weight of 11 lbs (5 kg).
  • Flexible Cycle (Config 1): Two flexible endoscopes with a light cord and mat (no additional load).
  • Flexible Cycle (Config 2): One flexible endoscope with a light cord and mat, plus a tray with additional instruments and silicone mat for a total weight of 24 lbs (11 kg). This configuration also included 5 stainless steel lumens.
  • Lumen Cycle: Validation load consisting of two instrument trays and two pouches for a total weight of 19.65 lbs (8.9 kg), with a maximum of 20 lumens per load.
  • Specialty Cycle (Non-lumened instruments): Validation load consisting of one pouched instrument tray or one pouch with guide(s)/model(s) (with or without tray) for a total weight of 11 lbs (5 kg).
  • Specialty Cycle (3D Printed Materials): Validation load consisting of pouched guide(s)/model(s) (with or without tray) for a total weight of 5 lbs (2.3 kg) 3D printed material.
• Data Provenance: The document implies these are prospective validation studies conducted by STERIS Corporation for regulatory submission. The country of origin is not explicitly stated but can be inferred as the United States given the FDA submission.

2. 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 is a sterilization device, not an AI diagnostic tool. Ground truth for sterilizers is established through microbiological assays (e.g., biological indicators) and physical/chemical measurements (temperature, pressure, time, hydrogen peroxide concentration, etc.), not expert reader consensus like in imaging. Therefore, the concept of "experts establishing ground truth for the test set" in the context of human readers does not apply here. The expertise lies in microbiology, engineering, and quality assurance to design and execute the validation studies.

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

• Not applicable for a sterilization device validation study. Sterility is typically determined by the absence of growth in biological indicators, which is an objective measurement rather than a subjective human interpretation requiring adjudication.

4. 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. This device is a sterilizer, not an AI or diagnostic imaging system. There are no "human readers" involved in performing or interpreting the sterilization process in a way that would warrant an MRMC study.

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

• Not applicable. This is a physical device, a sterilizer, not an algorithm. The "performance" is the physical process of sterilization.

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

• The ground truth for sterilization efficacy is established through microbiological assays, specifically the 6-log reduction or complete kill of highly resistant bacterial spores (Geobacillus stearothermophilus) contained within biological indicators (BIs). This is an objective, quantitative measure of sterilization. Additional ground truth includes adherence to engineering specifications for process parameters and chemical validation.

7. The sample size for the training set:

• Not applicable. This is a medical device (sterilizer) and its validation, not an AI/machine learning model that requires a "training set." The performance data comes from experimental validations and engineering studies.

8. How the ground truth for the training set was established:

• Not applicable, as there is no "training set" in the context of an AI model. The validation studies demonstrate the device's capability to sterilize.

The V-PRO Low Temperature Sterilization Systems are vaporized hydrogen peroxide sterilizers.

The sterilizers have three or more of the following pre-programmed cycles (the Lumen Cycle, the Non Lumen Cycle, the Flexible Cycle, and the Fast Non Lumen Cycle). The V-PRO Low Temperature Sterilization Systems are intended for terminal sterilization of cleaned, rinsed, dried, and packaged reusable surgical instruments used in healthcare facilities.

The V-PRO Sterilizers use VAPROX® HC Sterilant to sterilize the intended devices through exposure to vaporized hydrogen peroxide (VHP). The four preprogrammed cycles all use 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 manufacturer is seeking 510(k) clearance for modifications to the V-PRO maX and V-PRO maX 2 Low Temperature Sterilization Systems. These modifications involve changes to the indications for use, specifically by simplifying claims descriptions for Flexible and Lumen Cycles, adding stainless steel lumen claims to the Flexible Cycle, adding non-metallic and stainless steel lumen claims to the Lumen Cycle, and adding diffusion-restricted materials for Non Lumen and Fast Non Lumen Cycles. No physical changes were made to the devices, only changes to the labeling (operator manual).

Here's an analysis of the acceptance criteria and the study presented:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't explicitly state quantitative acceptance criteria in a dedicated table for each performance outcome. Instead, it reports "PASS" for all tests, indicating that the device met the internal established criteria for each study. The underlying acceptance for sterilization efficacy is typically a complete kill of biological indicators, resulting in sterility.

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

• 1/2 Cycle Verification of Mated Surfaces: The document does not explicitly state the sample size for this test. It refers to "mated surfaces" and "worst-case conditions."
• 1/2 Cycle Efficacy: The document does not explicitly state the sample size. It refers to "the validation load used to qualify each sterilizer cycle."
• Simulated Use Test: The document does not explicitly state the sample size. It refers to "medical devices" and "worst-case processing conditions."
• In Use Test: The document does not explicitly state the sample size. It refers to "patient-soiled, clinically-cleaned, medical instruments."

For all tests, the provenance of the data (country of origin, retrospective or prospective) is not explicitly stated. However, given the context of a 510(k) submission to the U.S. FDA, it is highly probable that the studies were conducted in accordance with recognized standards, likely within the U.S. or using internationally recognized protocols acceptable to the FDA. The nature of these sterilization validation studies often involves prospective testing.

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

This type of information is not applicable to this submission. The "device" in question is a sterilization system, not a diagnostic or AI-driven decision support system that requires expert interpretation to establish ground truth (e.g., presence/absence of disease in an image). The "ground truth" in sterilization validation is binary: either sterility is achieved (e.g., biological indicator shows no growth) or it is not. This is typically determined by laboratory analysis of biological indicators, not expert consensus.

4. Adjudication Method for the Test Set:

This information is not applicable for the same reasons mentioned above. Adjudication methods like 2+1 or 3+1 are used when there's subjective interpretation involved, such as in image analysis by multiple readers. Sterilization efficacy is an objective outcome measured by biological indicators.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and 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-assisted diagnostic tool.

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

This is not applicable. The device is a physical sterilization system, not an algorithm.

7. The type of ground truth used:

The ground truth used for these sterilization studies is based on biological indicator (BI) kill and potentially chemical indicator (CI) response, which are direct measures of sterilization efficacy. In sterilization validation, biological indicators containing a known resistant microorganism (e.g., Geobacillus stearothermophilus) are exposed to the sterilization process. The "ground truth" that sterility has been achieved is established when these biological indicators show no growth after incubation, indicating that the microorganisms have been inactivated. This is an objective, laboratory-derived ground truth.

8. The Sample Size for the Training Set:

This is not applicable. The device is a physical sterilization system. There is no "training set" in the context of machine learning. The "training" and "validation" in this field refer to the rigorous process of developing and confirming the sterilization cycle parameters to reliably achieve sterility across a defined range of medical devices and load configurations.

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

This is not applicable for the reasons stated above. There is no machine learning training set. The "ground truth" for establishing sterilization parameters is derived from extensive scientific and engineering studies testing the lethality of the sterilant under various conditions, typically using biological indicators and physical parameter monitoring. This involves determining the "D-value" (decimal reduction time) of the biological indicator organism and then designing a cycle that provides a sufficient "sterility assurance level" (SAL), often 10^-6, meaning a one-in-a-million chance of a non-sterile item.

This document describes the V-PRO Low Temperature Sterilization Systems, specifically the V-PRO 1, V-PRO 1 Plus, V-PRO maX, and V-PRO maX 2 models. The information provided focuses on their indications for use and the validation studies conducted to prove their effectiveness.

Here's an analysis based on your requested information:

1. Table of Acceptance Criteria and Reported Device Performance:

The document describes two main tests to demonstrate the device meets acceptance criteria for sterilization efficacy. The acceptance criteria for biological indicators (BIs) are generally defined by a "total kill endpoint," meaning no microbial growth after sterilization, which is achieved at a specific sterilant injection weight. The "simulated use test" acceptance criteria are that the sterilizer cycles successfully sterilize medical devices under worst-case conditions.

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

The document doesn't explicitly state a "test set" in the context of a typical AI/ML study (e.g., number of images, cases). Instead, it refers to "validation loads" and "lumen sizes" for sterilization efficacy testing.

  • V-PRO maX 2 (Lumen Cycle): A maximum of 20 lumens per load. The validation studies used a load consisting of two instrument trays and two pouches for a total weight of 19.65 lbs (8.9 kg).

• Data Provenance: The document does not specify the country of origin of the data. The studies are described as "validation studies" and "non-clinical performance tests," implying they were conducted prospectively to validate the sterilization claims of the device.

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

This information is not provided. In the context of sterilization validation, "ground truth" is typically established through microbiological methods (e.g., culturing biological indicators to confirm sterility or lack thereof) rather than expert interpretation of medical images or case data. Therefore, the concept of "experts" in the traditional sense of clinical opinion is not directly applicable to this type of device validation. The "experts" would likely be microbiologists or validation engineers.

4. Adjudication Method for the Test Set:

Not applicable. As described above, the "ground truth" for sterilization efficacy is typically determined by objective microbiological culture results (growth/no growth of biological indicators), not by subjective expert adjudication.

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

No, an MRMC comparative effectiveness study was not done. These devices are sterilizers, and their performance is evaluated based on direct microbiological efficacy, not on the improvement of human reader performance using AI assistance. The document explicitly states the studies are "non-clinical performance tests."

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

This question is not applicable in the context of this device. The V-PRO systems are sterilization machines, not AI algorithms designed to assist human interpretation. Their "standalone" performance is the validation of their sterilization efficacy without human intervention in the sterilization process itself. The software controls the sterilization cycle, and its performance is part of the overall device validation.

7. The Type of Ground Truth Used:

The ground truth for these validation studies is primarily:

• Microbiological Sterility (Biological Indicators): The "total kill endpoint verification" test indicates the use of biological indicators (BIs) which contain a known number of resistant microorganisms (e.g., Geobacillus stearothermophilus spores). Sterility is achieved when no growth of these microorganisms is detected after processing.
• Physical and Chemical Parameters: The document mentions "critical process parameters" such as "Time, Chamber Temperature, Vaporizer Temperature, Chamber Pressure Prior to Injection, Sterilant Injection Weight." These parameters are controlled and monitored to ensure the cycle performs optimally, contributing to the "ground truth" that appropriate conditions for sterilization were met.

8. The Sample Size for the Training Set:

This information is not provided, and the concept of a "training set" in the context of machine learning is not directly applicable to these physical sterilization devices. The physical properties and mechanisms of sterilization are based on established scientific principlesvalidated through controlled experiments, not through training an algorithm on a dataset. The formulation of the VAPROX HC Sterilant and the design of the sterilization cycles are based on research and development, not on a machine learning training set.

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

Not applicable, as there is no mention of a "training set" for an AI/ML algorithm within the provided text for these sterilization devices. The "ground truth" for the development and validation of these sterilizers is based on established methods in microbiology and validated sterilization principles (e.g., D-value determination, overkill methods) which define what constitutes a sterile condition and how to achieve it.

The V-PRO maX 2 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 Amsco V-PRO 1, Amsco V-PRO 1 Plus, V-PRO maX and V-PRO 60 Sterilizers.

As with the predicate device (K162413), the V-PRO maX 2 Sterilizer has three preprogrammed cycles (the Lumen Cycle, the Non Lumen Cycle and the Flexible Cycle) with a fourth added (the Fast Non Lumen Cycle). The V-PRO maX 2 Low Temperature Sterilization System is intended for terminal sterilization of cleaned, rinsed, dried and packaged reusable surgical instruments used in healthcare facilities.

The V-PRO maX 2 Sterilizer uses VAPROX® HC Sterilant to sterilize the intended devices through exposure to vaporized hydrogen peroxide (VHP). Its four 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.

The provided text describes the V-PRO® maX 2 Low Temperature Sterilization System, a medical device for sterilizing instruments. It is a 510(k) premarket notification, indicating it is intended to be substantially equivalent to a predicate device, not a new type of device requiring extensive clinical trials for efficacy. Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context refer to performance tests demonstrating substantial equivalence to the predicate device and the general efficacy of the sterilization process.

Here's an breakdown based on your request, interpreting "acceptance criteria" as the required successful outcomes of the performance tests for substantial equivalence:

1. Table of Acceptance Criteria and Reported Device Performance:

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

The document primarily discusses device performance and sterilization efficacy, not diagnostic accuracy where "test sets" of patient data are typically used. Instead, the "test set" here refers to the biological indicators (BIs) and test loads used in the sterilization efficacy studies.

• AOAC Sporicidal Test: "All 720 carriers processed using 3 lots of EOSL sterilant were sterile." This implies a total of 720 biological indicators (carriers).
• Other Efficacy Tests (D-value, Total Kill, 1/2 Cycle Verification, Simulated Use, In Use): These tests involve specific "validation loads" and "worst-case conditions."
  • Non Lumen Cycle: Validation load of two instrument trays for a total weight of 50 lbs (22.7 kg).
  • Fast Non Lumen Cycle: Validation load of one pouched instrument tray for a total weight of 11 lbs (5 kg).
  • Flexible Cycle (Load Config 1): Two flexible endoscopes, each packaged into a tray with silicone mat and light cord.
  • Flexible Cycle (Load Config 2): One flexible endoscope in a tray with silicone mat and light cord, plus an additional instrument tray and one pouch for a total weight of 24 lbs (11 kg).
  • Lumen Cycle: A maximum of 20 lumens per load, using a validation load of two instrument trays and two pouches for a total weight of 19.65 lbs (8.9 kg).
  • "Patient-soiled, clinically-cleaned, medical instruments" were used for the in-use test.

Data Provenance: The studies were conducted by the device manufacturer (STERIS Corporation) internally as part of their premarket notification for the Food and Drug Administration (FDA) in the USA. These are laboratory and simulated/actual use tests, not human data. The context implies these are prospective tests designed to prove the device's performance.

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

This information is not applicable in the context of device sterilization validation. "Ground truth" for sterilization is established by scientific principles of microbial inactivation (e.g., whether biological indicators containing a known number of resistant spores are killed), rather than expert consensus on interpretive tasks. The methodology for assessing sterility (e.g., incubation of biological indicators) relies on established microbiological techniques.

4. Adjudication Method for the Test Set:

Not applicable. Sterility tests involve objective outcomes (growth or no growth of microorganisms). There is no "adjudication" in the sense of resolving disagreements between human readers, as for an AI diagnostic tool.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done:

No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic devices where human readers interpret medical images or data, and AI might assist in that interpretation. This document is about a sterilization device, which does not involve human interpretation of output in that manner.

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

The device itself is a "standalone" sterilizer. Its performance is evaluated purely on its ability to sterilize medical instruments, without human intervention in the sterilization process once initiated. The tests performed (e.g., AOAC Sporicidal Test, D-value determination) are indeed standalone assessments of the device's efficacy. There is no "human-in-the-loop" concept for the primary function of sterilization.

7. The Type of Ground Truth Used:

The ground truth used for these performance tests is microbiological eradication/inactivation.

• For the AOAC Sporicidal Test, D-value, and Total Kill Endpoint, the ground truth is the absence of viable microorganisms (specifically, highly resistant bacterial spores like Geobacillus stearothermophilus). This is determined by standard microbiological culture techniques (e.g., incubating biological indicators and observing for growth).
• For the "In Use Test," the ground truth for successful sterilization of patient-soiled instruments would similarly be the absence of microbial growth from processed items.
• For biocompatibility and material compatibility, the ground truth is established through standardized cytotoxicity assays and visual / functional assessment of materials following repeated processing.

8. The Sample Size for the Training Set:

Not applicable. This device is a physical sterilizer and not an AI/machine learning model that undergoes "training." Its operational parameters are designed and validated based on scientific principles of sterilization, not statistical inference from a training dataset derived from "training examples."

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

Not applicable, as there is no "training set" in the context of this traditional device validation.
