AI/ML Overview

The provided documentation outlines acceptance criteria and the results of a study for several STERIS Liquid Chemical Sterilant Processing Systems: SYSTEM 1E, SYSTEM 1 endo Model P6800, and SYSTEM 1 endo Model P6900. These systems utilize the S40 Sterilant Concentrate. The submission is a 510(k) premarket notification, indicating a claim of substantial equivalence to a predicate device (K192929), largely due to software/firmware updates and component obsolescence/replacement.

Here's a breakdown of the requested information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

For all three models (SYSTEM 1E, SYSTEM 1 endo Model P6800, and SYSTEM 1 endo Model P6900), the testing described is limited to evaluating the impact of minor modifications (firmware update and/or varistor replacement). The core performance criteria and germicidal efficacy are based on the predicate device's established performance.

Test	Acceptance Criteria	Reported Device Performance
Software validation per IEC 62304	The firmware was validated and determined to operate effectively and as designed.	Pass
Functional test with replacement varistor	The modification does not affect the operation of the device (or ensures operation).	Pass

Note: The tables in the document (Table 1, Table 2 in each section concerning the systems and S40 Sterilant Concentrate) extensively compare the proposed device features and performance to the predicate device, indicating "Identical" across various parameters such as germicidal claim, exposure time, use temperature, reuse, active ingredient, mode of action, rinses, microbial efficacy (sporicidal, fungicidal, bactericidal, viricidal, tuberculocidal, simulated-use, clinical in-use), biocompatibility, residue reduction, and device material compatibility. This implies that the acceptance criteria for these aspects are the same as those met by the predicate device, and the proposed devices are considered to perform equivalently.

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

Sample Size for Functional & Software Testing: The document does not specify the exact sample size (e.g., number of devices or test cycles) used for the software validation or functional tests with the replacement varistor. It simply states the tests were performed and passed.
Data Provenance: The new tests (software validation and functional tests) would likely be internal studies conducted by STERIS Corporation. The data on microbial efficacy and material compatibility for the predicate device (which are claimed as identical for the proposed devices) stem from various in vitro tests and clinical in-use studies, as indicated by the listed citations (Block, Clapp et al., Maillard et al., McDonnell et al.). The country of origin for these foundational efficacy tests is not specified, but they refer to internationally recognized methods (e.g., AOAC Official Methods, EPA Viricidal Testing). These previous studies would be considered retrospective for the current submission, as they establish the performance of the predicate. The current evaluation of modifications would be prospective relative to these specific changes.

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

The document primarily describes engineering verification and validation activities (software validation, functional testing). These types of tests do not typically involve human experts for establishing "ground truth" in the same way clinical or diagnostic studies do. Instead, the "truth" is established by adherence to design specifications, regulatory standards, and verified operational parameters.
For the microbial efficacy (sporicidal, fungicidal, bactericidal, viricidal, tuberculocidal, simulated-use, clinical in-use), the "ground truth" implicitly relies on established microbiological methods and their respective acceptance criteria. The experts involved in the original studies for the predicate device would have been microbiologists and other scientific professionals, as indicated by the referenced scientific literature. The number and specific qualifications are not detailed in this submission.

4. Adjudication Method for the Test Set

Given the nature of the tests mentioned (software validation, functional tests), an adjudication method (like 2+1, 3+1 often used in medical image analysis) is not applicable. These are objective engineering and performance verification tests with clear pass/fail criteria.

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

No MRMC comparative effectiveness study was done. The device is a sterilizer, not a diagnostic imaging device typically associated with human reader performance. The improvements described are related to maintenance and software updates, not human interpretation.

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

The device itself is a standalone system for liquid chemical sterilization; it does not involve an "algorithm" in the sense of AI performing a diagnostic task. Its performance is evaluated intrinsically through its ability to achieve sterilization (microbial kill) and maintain operational parameters. The studies verifying its efficacy (e.g., sporicidal activity, simulated-use tests) are standalone evaluations of the system's performance.

7. Type of Ground Truth Used

For Software and Functional Testing: The ground truth is defined by the device's design specifications and regulatory requirements (e.g., correct operation of firmware, proper function after component replacement).
For Microbial Efficacy (Predicate Device): The ground truth was established through rigorous microbiological testing using standardized methods (e.g., AOAC Official Methods, EPA Viricidal Testing). This includes:
- Culture-based assays: Demonstrating log reduction of various microorganisms (Bacillus subtilis, Clostridium sporogenes, Trichophyton mentagrophytes, Salmonella choleraesuis, Staphylococcus aureus, Pseudomonas aeruginosa, Herpes simplex Type 1, Adenovirus Type 5, Poliovirus Type 1, Mycobacterium terrae).
- Simulated-use tests: Demonstrating log reduction of Geobacillus stearothermophilus spores under manual application conditions.
- Clinical In-Use: Absence of surviving microorganisms on representative medical devices.

8. Sample Size for the Training Set

This information is not applicable. The described devices are physical sterilizers, not AI/machine learning models that require a "training set" in the conventional sense. The "firmware update" is likely a software change to address bugs or improve existing functionality, not a re-training of a learning algorithm.

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

This information is not applicable, as there is no "training set" for an AI algorithm.
