The STERRAD 100NX Sterilizer is a self-contained stand-alone system of hardware and software designed to sterilize medical instruments and devices using a patented hydrogen peroxide gas plasma process. Hydrogen peroxide vapor is generated by injecting aqueous hydrogen peroxide into the vaporizer where the solution is heated and vaporized, introducing the vapor into the chamber under sub-ambient pressure and transforming the vapor into a gas plasma using electrical energy. The STERRAD 100NX Sterilizer has four cleared sterilization cycles: STANDARD, FLEX, EXPRESS, and DUO Cycles.

For the STANDARD and FLEX cycles, hydrogen peroxide (HoO2) vapor is generated by injecting aqueous hydrogen peroxide into an on-board vaporizer where the solution is heated and vaporized, thereby concentrating 59% H2O2 to 90% nominal H2O2. The H2O2 vapor is then introduced into the sterilization chamber under sub-ambient pressure and transformed into a gas-plasma using electrical energy. The sterilization process is a multiphase process that utilizes a combination of exposure to hydrogen peroxide vapor and plasma to affect sterilization.

For the EXPRESS cycle, the onboard concentration process utilized for STANDARD and FLEX cycles is not used: the subsystem receives hydrogen peroxide solution from the delivery system. vaporizes the liquid and delivers it to the chamber.

For the DUO Cycle, hydrogen peroxide from the STERRAD 100NX Cassette follows a different flow path through the delivery module. The hydrogen peroxide, when withdrawn from the cassette, is temporarily held in the accumulators of the delivery module, and a smaller quantity (1.55 mL, nominal value) of hydrogen peroxide is dispensed or metered into the vaporizer during each of the two half-cycles of the DUO cycle. The hardware for the STERRAD 100NX Sterilizer consists of a sterilizer chamber, constructed with aluminum, and a variety of instruments and components which are housed in a covered frame. The sterilizer also uses accessories such as reusable instrument trays, and printer paper.

The hardware for the STERRAD 100NX Sterilizer consists of a sterilizer chamber, constructed with aluminum, and a variety of instruments and components which are housed in a covered frame. Other major components of the system are constructed from passivated stainless steel, Viton (a copolymer of vinylidene fluoride and hexafluoropropylene), Ultem (polyetherimide), injection molding, and structural foam. The sterilizer also uses accessories such as reusable instrument trays, and printer paper.

The STERRAD 100NX Sterilizer uses a disposable sterilant cassette that contains the 59% nominal hydrogen peroxide solution in a plastic cell pack and cassette shells. The sterilizer cancels the cycle if the hydrogen peroxide monitor data does not meet the pre-defined minimum concentration specification.

The modified STERRAD 100NX Sterilizer with ALLClear Technology described within this submission incorporates enhancements and new features to improve reliability and usability. as briefly described following:

• Load Conditioning Feature: Available for use with the STANDARD, FLEX, and . EXPRESS cycles. Reduces canceled cycles by performing load and system checks and executing a load conditioning step prior to starting a sterilization cycle.
• . Enhanced Graphical User Interface (GUI): Added information to the error messages enabling users to take actions related to that error message. GUI enhancement also provides more intuitive navigation.
• Improved cassette insertion.
• New Touchscreen Display: Larger, higher resolution, and wider viewing angle.
• New External Panels: Enhance aesthetic appearance and accommodate the larger display.
• Capability for future "ecosystem" connectivity: Will allow communication and integration . with future ASP biological indicator reader(s), as well as other potential future communication features.

The technological characteristics associated with the sterilization process for the modified STERRAD 100NX Sterilizer ALLClear Technology are identical to those of the previously cleared STERRAD 100NX Sterilizer; the software and hardware changes associated with the described enhancements and new features do not modify the existing sterilization cycles.

This document describes the STERRAD® 100NX Sterilizer with ALLClear™ Technology, a low-temperature sterilization system using hydrogen peroxide gas plasma. The submission (K160903) concerns enhancements to reliability and usability of the previously cleared device, not changes to the core sterilization process.

The document does not explicitly state quantitative predefined "acceptance criteria" for the changes, but rather "Pass/Fail" results for various verification tests demonstrating compliance and functionality. The overall acceptance is implied by all tests yielding "Pass".

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

The document does not specify exact sample sizes for each verification test. It generally refers to "studies" or "testing" without detailing the number of units or cycles tested.
The data provenance is internal to Advanced Sterilization Products, as these are non-clinical verification tests conducted for regulatory submission. No information on country of origin of the data is provided beyond the submitting company's location (Irvine, CA, USA). The tests are prospective in nature, as they are specifically conducted to verify the changes in 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 document. The tests seem to be objective engineering and scientific evaluations rather than expert-driven ground truth establishment. For example, sterilizer performance is evaluated against defined physical and biological parameters, and usability testing is conducted with users, but the "ground truth" for the device's function is its validated performance.

4. Adjudication Method for the Test Set

Not applicable. The tests are presented as objective measurements and verifications, not requiring an adjudication panel.

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

Not applicable. This device is a sterilizer, not an AI-powered diagnostic system that involves human readers or interpretation of medical images.

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

Not applicable. This device is a physical sterilizer and does not involve AI algorithms in the context of diagnostic interpretation. Its performance is inherent to its mechanical, chemical, and software components operating in a standalone fashion.

7. The Type of Ground Truth Used

The ground truth for the performance of the sterilizer is based on established scientific principles of sterilization (e.g., microbial inactivation, hydrogen peroxide concentration, temperature, pressure), material compatibility, electrical safety standards, and software validation. For biological efficacy, this typically involves testing with biological indicators. For the improvements in this submission, the "ground truth" for the new features (e.g., load conditioning, new display) are that they perform their intended function (e.g., reduce out-gassing, display correctly) and do not compromise existing validated sterilization processes.

8. The Sample Size for the Training Set

Not applicable. This device does not employ machine learning or AI models that require a "training set" in the conventional sense. The "training" for the device's operation is its design, engineering tolerances, and validated parameters.

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

Not applicable, as there is no "training set" in the AI sense for this device. The design and performance parameters are established through engineering specifications, regulatory standards, and scientific principles related to sterilization and medical device manufacturing.

The STERRAD® 100NXTM Sterilizer can be placed directly on a table, counter top, or on the movable cart.

Here's a breakdown of the acceptance criteria and the study information for the STERRAD® 100NX™ Sterilizer with EXPRESS Cycle, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't explicitly state quantitative acceptance criteria (e.g., "sterility assurance level of X"). Instead, it describes a "Passed" outcome for various validation studies, implying that the device met pre-defined success metrics for each study. The overarching acceptance criterion is achieving sterilization and demonstrating equivalence to predicate devices.

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

• Sample Size: The document does not explicitly state a total numerical sample size for the "test set" in terms of how many individual items were sterilized across all tests. However, it does provide specific load configurations used for validation studies:
  • Standard Cycle Validation Load: Two instrument trays, each weighing 10.7 lbs. (for 0.7 mm x 500 mm lumens). A maximum of ten single-channel stainless steel lumens (five per tray per cycle).
  • Flex Scope Cycle Validation Load: Two flexible endoscopes (one per tray per cycle) for 1 mm x 850 mm flexible endoscopes. For other flexible endoscopes, the load was two instrument trays, each weighing 10.7 lbs.
  • EXPRESS Cycle Validation Load: A single instrument tray weighing 10.7 lbs placed on the bottom shelf.
• Data Provenance: The document does not specify the country of origin of the data. It implies the studies were conducted by Advanced Sterilization Products (division of Ethicon, Inc.), based in Irvine, CA, USA.
• Retrospective or Prospective: The studies described ("Validation Testing") are inherently prospective, as they were conducted to validate the performance of the new EXPRESS cycle.

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 document. The document primarily focuses on microbiological "overkill" methods using G. stearothermophilus spores and physical testing, which don't typically involve human expert adjudication for ground truth in the same way as, for example, medical imaging diagnostics.

4. Adjudication Method for the Test Set:

This information is not provided as the ground truth establishment method (microbiological challenge and physical testing) does not involve adjudication by multiple experts. The "ground truth" for sterilization is typically measured by the inactivation of biological indicators.

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

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for diagnostic devices where human interpretation is involved. The STERRAD® 100NX™ Sterilizer is a sterilization device, and its effectiveness is determined by its ability to kill microorganisms, not by human interpretation of images or data.

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

The device itself is a standalone system (the sterilizer). The validation studies presented evaluate the performance of the sterilizer operating on its own; there is no "human-in-the-loop" performance being measured in the context of the device's primary function (sterilization). Therefore, in a sense, the evaluations are entirely of the "algorithm only" (the sterilization process) without human interpretive intervention.

7. The Type of Ground Truth Used:

The primary ground truth used is the inactivation of biological indicators, specifically G. stearothermophilus spores, using an "overkill" approach. This is a well-established and accepted method for demonstrating sterilization efficacy. Additional ground truth elements include:

• Physical/Chemical measurements: Ensuring appropriate levels of hydrogen peroxide and plasma are achieved.
• Bacteriostasis testing: Confirming that materials or residues do not inhibit microbial growth.
• Functionality and material compatibility assessments: Ensuring the devices being sterilized are not damaged and remain functional.

8. The Sample Size for the Training Set:

This document does not refer to a "training set" in the context of an algorithm or AI. The STERRAD® 100NX™ Sterilizer is a physical device with a defined process, not a machine learning model that undergoes a training phase. The validation studies demonstrate the performance of the finalized device.

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

As there is no "training set" in the machine learning sense, this question is not applicable. The device's design and parameters would have been developed based on scientific principles of sterilization and iterative testing, not by training an algorithm on a dataset with pre-established ground truth.

The provided text is a 510(k) summary for the STERRAD® 100NX™ Sterilizer. It describes the device's indications for use, its predicate device, a general description, and a summary of nonclinical tests. However, the document does not contain specific acceptance criteria, reported device performance metrics in a table format, sample sizes or provenance for test sets, details on ground truth establishment (number of experts, qualifications, adjudication methods), information about MRMC studies, or standalone algorithm performance.

The text focuses on the validation testing performed, which used an "overkill" approach with G. stearothermophilus spores to demonstrate the sterilizer's effectiveness.

Based only on the provided input, here's what can be extracted and what is missing:

1. Table of Acceptance Criteria and Reported Device Performance:

• Acceptance Criteria:
  • The primary acceptance criterion for a sterilizer is usually the complete inactivation of a specified biological indicator (e.g., G. stearothermophilus spores). The "overkill" approach implies demonstrating sterility under challenging conditions (e.g., high spore populations). The document states "Testing was performed using the 'overkill' approach utilizing G. stearothermophilus spores."
  • Specific performance metrics (e.g., Sterility Assurance Level (SAL) of 10^-6 or better) are implied by the overkill method but not explicitly stated as quantitative acceptance criteria in this document.
  • The ability to sterilize specific types of lumens and endoscopes of certain dimensions is also an implicit acceptance criterion.
• Reported Device Performance: The document only states "Table 8-1 on the following page identifies the validation studies performed and the results obtained." This table is not provided in the given text, so specific performance results are unavailable.

2. Sample size used for the test set and the data provenance:

• Sample Size: The document mentions "a validation load consisting of two instrument trays each weighing 10.7 lbs" for most studies. For the 1 x 850 mm flexible endoscopes, they "were validated without any additional load." It also specifies "A maximum of ten lumens, five per tray" and "A maximum of two flexible endoscopes, one per tray." These describe the loading configurations for the tests, but not the total 'sample size' in terms of the number of sterilization cycles or the total number of biological indicators tested.
• Data Provenance: Not specified. This is a nonclinical, device performance study, not a clinical study on human data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Not Applicable. This is not a study involving human interpretation of data where expert ground truth would be established. The "ground truth" for a sterilizer is the proven inactivation of biological indicators, which is a laboratory measurement.

4. Adjudication method for the test set:

• Not Applicable. There is no human adjudication component for this type of device performance study.

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:

• Not Applicable. This is a sterilization device, not an AI-powered diagnostic or interpretive tool.

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

• Not Applicable. This is a hardware and software system for sterilization, not an algorithm being tested for standalone performance. The sterilizer operates autonomously to perform the sterilization cycle.

7. The type of ground truth used:

• The ground truth for the sterilization efficacy tests was the inactivation of G. stearothermophilus spores. This is a biological indicator common in sterilization validation, typically confirmed by culture methods to ensure no viable spores remain after processing.

8. The sample size for the training set:

• Not Applicable. This device does not use machine learning or AI that would require a "training set" in the conventional sense. The "training" for a sterilizer system is its design and engineering parameters.

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

• Not Applicable. As above, no training set in this context.
