Intended Use

The SYSTEM 1E Liquid Chemical Sterilant Processing System is intended for liquid chemical sterilization of cleaned, immersible, and reusable critical and semi-critical heat-sensitive medical devices in healthcare facilities.

The SYSTEM 1E Processor dilutes the S40 Sterilant Concentrate to its use dilution (>1820 mg/L peracetic acid), liquid chemically sterilizes the load during a controlled 6-minute exposure at 45.5 to 60°C, and rinses the load with extensively treated* potable water. After completion of a cycle, critical devices should be used immediately; semi-critical devices should be used immediately or may be handled and stored in a manner similar to that of high level disinfected endoscopes. Critical devices not used immediately should be processed again before use.

The SYSTEM 1E Processor uses only S40 Sterilant Concentrate to liquid chemically sterilize medical devices.

  • The extensive treatment of EPA potable water consists of:
    1. Pre-filtration through two pre-filters:
    • · Pre-filter A is a gross depth filter that removes approximately 2.5 micron or larger particles/contaminants.
    • · Pre-filter B is a surface filter that removes particles/contaminants > 0.1 micron.
    1. UV Irradiation:
    • · During transit through the UV water treatment chamber, a UV dose sufficient to achieve a > or equal to 6-log reduction of MS2 virus is delivered to the water.
  • 3.0.1 micron filtration:
    • · The water prepared by pre-filtration is filtered through redundant, 0.1-micron (absolute rated) membranes to remove bacteria. fungi and protozoa > 0.1 micron.

AI/ML Overview

The provided document describes the STERIS SYSTEM 1E, SYSTEM 1 endo Model P6800, and SYSTEM 1 endo Model P6900 Liquid Chemical Sterilant Processing Systems. This submission is for modifications related to the obsolescence and replacement of a compressor and an upper lid seal. The document asserts that these modified devices are substantially equivalent to their predicate device (K211607).

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

1. Table of Acceptance Criteria and Reported Device Performance:

TestAcceptance CriteriaReported Device Performance
Performance testing with replacement compressorThe modification does not affect the performance of the device.Pass
Performance testing with replacement upper lid sealThe modification does not affect the performance of the device.Pass
Material Compatibility of upper lid sealThe upper lid seal maintains integrity after multiple Liquid Chemical Sterilization and Diagnostic Cycles in accordance with methods disclosed in K131078.Pass
Biocompatibility of upper lid sealThe upper lid seal meets the acceptance criteria for cytotoxicity in ISO 10993-5, Annex A in accordance with methods disclosed in K090036.Pass

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

The document does not explicitly state the sample size for the non-clinical testing performed. It refers to "multiple Liquid Chemical Sterilization and Diagnostic Cycles" for the material compatibility test but does not quantify "multiple". Similarly, for performance testing, it simply states "the modification does not affect the performance," without detailing the number of test cycles or units involved.

The provenance of the data is not explicitly stated beyond being "non-clinical testing" conducted by STERIS Corporation for their updated devices. It is an internal company study for regulatory submission.

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

The document does not mention the use of experts to establish ground truth for this non-clinical testing. The acceptance criteria for performance are based on the device maintaining its original performance and the specific technical standards for material compatibility and biocompatibility (ISO 10993-5, K131078, K090036). These are objective measurements rather than expert interpretations.

4. Adjudication Method for the Test Set:

An adjudication method (e.g., 2+1, 3+1) is not applicable or mentioned as the testing is non-clinical performance and material characterization, yielding objective "Pass/Fail" results against predefined criteria.

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

A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not performed as this device is a liquid chemical sterilant processing system, not an AI-assisted diagnostic or imaging tool involving human interpretation. Therefore, there's no "effect size of how much human readers improve with AI vs without AI assistance" to report.

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

A standalone performance study, in the context of AI, was not performed, nor is it applicable. The device is an automated chemical sterilization system; its performance is independently measured against specified physical and chemical parameters, not an algorithm's output. The "algorithm" here refers to the system's software controlling the sterilization cycle. The testing verifies the system's ability to maintain these controlled conditions.

7. Type of Ground Truth Used:

The ground truth for the non-clinical testing is based on objective measurements and adherence to established industry standards and previous regulatory clearances.

  • Performance: The device must continue to function as intended, not being adversely affected by component changes.
  • Material Compatibility: Integrity after multiple cycles, referencing K131078.
  • Biocompatibility: Cytotoxicity evaluation per ISO 10993-5, Annex A, referencing K090036.

8. Sample Size for the Training Set:

The concept of a "training set" is not applicable here as this is not a machine learning or artificial intelligence device. The device's operation is deterministic based on its hardware and programmed cycles, not learned from data.

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

As there is no training set for this type of device, this question is not applicable.
