Device Description

The V-PRO 1, V-PRO 1 Plus, V-PRO maX and V-PRO 60 Low Temperature Sterilization Systems, using 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 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 the V-PRO maX and V-PRO 60 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 Cycles, respectively.

AI/ML Overview

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

Test	Acceptance Criteria	Results
Determination of Worst Case (Most Resistant) Material for VHP	Test: The most resistant material (MRM) is the material that is most difficult to sterilize (the material with the largest number of non-sterile results) Controls: Controls shall perform as intended.	Pass: As identified within previous V-PRO Sterilizer submissions, the most resistant material (MRM) for surface sterilization is Kraton.
Medical Device Material Compatibility	The devices shall be processed for 50 V-PRO 60 Sterilizer Lumen Cycles (worst case). The devices shall show no structural defects (crazing, cracks or chipping). The devices shall function following processing.	Pass: This testing verified compatibility of the tested 20 materials with the V-PRO Sterilizers.
Cytotoxicity Evaluation of Medical Devices	All Worst Case Cycles shall proceed to completion. The cytotoxic endpoint for each medical device shall be determined. Cytotoxicity Assay Controls shall perfrom as intended.	Pass: Testing demonstrates that various medical devices containing [unspecified, but likely referring to the materials tested in compatibility study] were determined to be non-cytotoxic following processing in three (3) V-PRO 60 Sterilizer Lumen Cycles.
Hydrogen Peroxide Residual Analysis of Processed Medical Devices	The residual hydrogen peroxide level for each medical device shall be determined and compared to the allowable hydrogen peroxide limits for mucosal and internal tissue contact. Each device shall demonstrate exhaustive extraction by showing less than a 10% increase for two (2) consecutive sample time points. Hydrogen Peroxide Residual Analysis Controls shall perform as intended.	Pass: Testing demonstrates that the hydrogen peroxide residuals from the medical devices composed of the 19 proposed compatible materials are from 2660-fold lower to greater than 13,000-fold lower than the tolerable exposure limits for mucosal and internal tissue contact when processed in three (3), worst case, back-to-back Lumen Cycles in the V-PRO 60 Sterilizer.

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

This is not applicable as there is no training set.
