Device Description

The Amsco Evolution Medium Steam Sterilizer models HC-600 and HC-1500 are designed for sterilization of heat and moisture-stable materials used in healthcare facilities and are available in two configurations:

  • Prevacuum is equipped with Prevacuum, Gravity, Liquid, Leak Test and ● DART (Bowie-Dick) cycles.
  • Steam Flush Pressure-Pulse (SFPP) is equipped with SFPP, Prevacuum, ● Gravity, Liquid, Leak Test and DART (Bowie-Dick) cycles.
    The chamber sizes of the proposed Amsco Evolution Medium Steam Sterilizer Models are as follows:
  • 26" x 26" x 39" (660 mm x 660 mm x 991 mm) Model HC-600 .
  • Model HC-1500 26" x 37½" x 60" (660mm x 950mm x 1524mm) .
AI/ML Overview

This document is a 510(k) premarket notification for the Amsco Evolution Medium Steam Sterilizer. It focuses on demonstrating substantial equivalence to a predicate device after certain modifications. Therefore, the "study" referred to is the verification and validation activities conducted to ensure the modifications do not affect the safety or effectiveness of the device.

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

1. Table of Acceptance Criteria and Reported Device Performance

Device ModificationVerification / Validation ActivityAcceptance CriteriaResults of Verification / Validation
Control replacementPerformance testingPer ST8Pass
Electrical safetyPer IEC 61010-1Pass
Software modificationsSoftware validationSoftware shall be appropriately verified and validatedPass
Vacuum pump replacementPerformance testingPer ST8Pass
Printer replacementSoftware validationSoftware shall be appropriately verified and validatedPass
Valve modificationsPerformance testingPer ST8Pass
Switch modificationActuationProper actuation, no alarmsPass
Door mounting bracket modificationDoor operation checkProper function after multiple cyclesPass

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

The document does not explicitly state the sample sizes (e.g., number of sterilizers tested, number of cycles run). The "test set" in this context refers to the modified sterilizer models (HC-600 and HC-1500) on which the verification and validation activities were performed. The data provenance is not specified beyond "STERIS Corporation" where the studies were conducted. The studies appear to be prospective, as they are verification and validation activities performed on the modified devices.

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

This information is not provided. The acceptance criteria reference industry standards (ST8, IEC 61010-1) and internal functional requirements ("Proper actuation, no alarms," "Proper function after multiple cycles"). It's implied that engineering and regulatory experts at STERIS established these criteria, but their specific number or qualifications are not detailed.

4. Adjudication Method for the Test Set

This information is not provided. Given the nature of performance testing for a sterilizer, "adjudication" in the sense of expert review for ambiguous results is unlikely to be a primary method. The results ("Pass") indicate direct verification against objective criteria.

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 steam sterilizer, not an AI-powered diagnostic tool requiring human readability of results.

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

This is not applicable. The device is a steam sterilizer, not an algorithm. The software modifications were validated to ensure the sterilizer's proper functioning, not as a standalone diagnostic.

7. The Type of Ground Truth Used

The ground truth for these verification activities is a combination of:

  • Industry Standards: AAMI ST8 (often referred to as ST8) for steam sterilization performance and IEC 61010-1 for electrical safety. These are recognized international/national standards for medical device safety and performance.
  • Engineering Specifications/Functional Requirements: "Software shall be appropriately verified and validated", "Proper actuation, no alarms", "Proper function after multiple cycles". These are internal specifications derived from the device's design and intended function.

8. The Sample Size for the Training Set

This is not applicable. The device is a physical sterilizer and not an AI/machine learning model that undergoes a "training set" phase.

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

This is not applicable, as there is no "training set" for this type of device.

Dear Mr. Tony Piotrkowski:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set

ട്. Discussion of Technological Comparison and Verification Activities

The Evolution Medium Sterilizers are the same as the predicate devices except for the specific modifications described in this submission. There are no differences in the indications for use or technology (including features, materials, and principles of operation) between the proposed and predicate devices. Therefore, the differences between the proposed and predicate devices are limited to the described modifications, and these proposed changes raise no new concerns of safety and effectiveness when compared to the predicate device.

The following table summarizes the verification activities that were performed with their respective acceptance criteria to ensure that these modifications do not affect the safety or effectiveness of the Evolution Medium Steam Sterilizers.
