Device Description

The Amsco Evolution Medium Steam Sterilizer models HC-900 and HC-1200 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 371/2' x 42" (Model HC 900)
  • 26'' x 37½' x 54'' (Model HC 1200)
AI/ML Overview

The provided text describes a 510(k) premarket notification for a steam sterilizer device, not an AI/ML-based medical device. Therefore, much of the requested information regarding AI/ML device testing (e.g., sample size for test/training sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance) is not applicable or present in this document.

However, I can extract the acceptance criteria and performance data for this traditional medical device:

Acceptance Criteria and Device Performance for Amsco® Evolution Medium Steam Sterilizer

The STERIS Corporation performed verification activities to ensure that modifications to their Amsco® Evolution Medium Steam Sterilizer (Models HC-900 and HC-1200) did not affect its safety or effectiveness. The study demonstrates that the device passed all established acceptance criteria.

1. Table of Acceptance Criteria and Reported Device Performance

Device ModificationVerification / Validation ActivityAcceptance CriteriaResults of Verification / Validation

Note: "Per ST8" refers to AAMI ST8, a recognized standard for hospital steam sterilizers. "Per IEC 61010-1" refers to an international standard for electrical equipment for measurement, control, and laboratory use, which includes safety requirements.

Information Not Applicable or Available in the Provided Document (Pertaining to AI/ML Devices)

This document describes a traditional medical device (steam sterilizer), not an AI/ML device. Therefore, the following information, typically required for AI/ML device studies, is not applicable or found in this submission:

  1. Sample sizes used for the test set and the data provenance: Not applicable. Performance testing for sterilizers involves functional checks and adherence to standards rather than data sets like those used for AI/ML.
  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's performance is objective (e.g., passing a specific test cycle, electrical safety standards met), not based on expert consensus of complex data.
  3. Adjudication method for the test set: Not applicable. Performance is binary (pass/fail) against objective criteria.
  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. This is not an imaging or diagnostic device involving human readers.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. The device's performance is inherently "standalone" in its function as a sterilizer.
  6. The type of ground truth used: For this device, ground truth is based on established engineering and safety standards (ST8, IEC 61010-1), and functional performance checks (e.g., proper actuation, no alarms, proper door function after multiple cycles). It is not expert consensus, pathology, or outcomes data in the context of diagnostic accuracy.
  7. The sample size for the training set: Not applicable, as this is not an AI/ML device trained on data.
  8. How the ground truth for the training set was established: Not applicable.

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

{1}------------------------------------------------

device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

5. Description of Safety and Substantial Equivalence

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.
