Device Description

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.

AI/ML Overview

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):

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:

  1. 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.
  2. 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.
  3. Adjudication method for the test set: Not applicable.
  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.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
  6. 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.
  7. The sample size for the training set: Not applicable. This refers to a physical device, not an AI model.
  8. How the ground truth for the training set was established: Not applicable.
