Device Description
The AMSCO 600 Steam Sterilizer uses saturated steam, generated from a house steam utility (e.g. boiler system) or from a steam generator, to sterilize heat-stable health care products. The sterilizer accomplishes this by removing the air in the chamber, exposing the load to saturated steam for a defined combination of time and temperature, and drying the load. Removal of air from the chamber occurs using either of two methods, gravity displacement or mechanical vacuum. Once the air removal phase is completed, the sterilizer progresses to the steam exposure phase. During the steam exposure phase, every surface of the load is exposed to saturated steam for a defined combination of time and temperature. Once the steam exposure phase is completed, steam is removed from the chamber and the load is dried using the latent heat in the load and the vacuum pump. The ALUS is used with the AMSCO 600 Steam Sterilizer's existing transfer carriages and loading carts. It consists of a conveyor system which attaches to the load and/or unload ends of the steam sterilizer. It has a series of barcode labels which correspond to pre-programmed cycles and an optional scanner which when fitted to the system will communicate to the sterilizer which cycle to initiate.
More Information

No
The description details a steam sterilizer with pre-programmed cycles and an automated loading/unloading system that can be initiated by a barcode reader. There is no mention of adaptive learning, pattern recognition, or any other characteristics typically associated with AI/ML. The device operates based on fixed parameters and pre-defined logic.

No
Explanation: The device is a sterilizer for medical instruments, designed to prevent disease transmission, not to treat a disease or condition.

No

The device is a steam sterilizer, used to sterilize medical instruments and materials, not to diagnose medical conditions.

No

The device is a steam sterilizer and an automated loading/unloading system, which are clearly hardware devices. While there is mention of software validation, the core function and description are of physical equipment.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • Intended Use: The intended use is to sterilize heat and moisture-stable materials used in healthcare facilities, such as fabric packs and instrument trays. This is a process to render medical devices sterile for patient use.
  • Device Description: The device description details a steam sterilizer that uses saturated steam to kill microorganisms on medical instruments and materials.
  • Lack of IVD Characteristics: An IVD is a device intended for use in vitro for the examination of specimens, including blood, tissue, and urine, from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not perform any such examination of biological specimens.

The device is a medical device used for the sterilization of other medical devices, which is a crucial step in preventing the spread of infection in healthcare settings.

Device Description

The AMSCO 600 Steam Sterilizer uses saturated steam, generated from a house steam utility (e.g. boiler system) or from a steam generator, to sterilize heat-stable health care products.

The sterilizer accomplishes this by removing the air in the chamber, exposing the load to saturated steam for a defined combination of time and temperature, and drying the load. Removal of air from the chamber occurs using either of two methods, gravity displacement or mechanical vacuum. Once the air removal phase is completed, the sterilizer progresses to the steam exposure phase. During the steam exposure phase, every surface of the load is exposed to saturated steam for a defined combination of time and temperature. Once the steam exposure phase is completed, steam is removed from the chamber and the load is dried using the latent heat in the load and the vacuum pump.

The sterilizers are generally operated by technicians in a central service or sterile processing department of healthcare facilities. Sterilizers may also be located in a surgical suite to allow for Immediate Use Steam Sterilization (IUSS) for instances where an instrument is needed immediately for a procedure (e.g. after an instrument has been dropped and there is no replacement readily available). Standard practices for use of sterilizers in health care facilities are provided by various organizations (e.g. ANSI/AAMI ST79).

The ALUS is used with the AMSCO 600 Steam Sterilizer’s existing transfer carriages and loading carts. It consists of a conveyor system which attaches to the load and/or unload ends of the steam sterilizer. It has a series of barcode labels which correspond to pre-programmed cycles and an optional scanner which when fitted to the system will communicate to the sterilizer which cycle to initiate.

Dear Anthony 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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

1

801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4. Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

STERIS TRADITIONAL 510(k) PREMARKET NOTIFICATION K211500 AMSCO 600 Steam Sterilizer

The proposed device has the same intended use as the predicate with the same technological characteristics. The modifications, subject of this submission, are addition a 10-minute, 270 °F (132 °C) prevacuum, steam sterilization cycle and addition of an automated loading and unloading system (ALUS). Sterilizer automated loading systems are described under FDA product code PEC so the resulting product will be under product codes FLE and PEC. Other design modifications since the last clearance have been made to improve manufacturability, allow for sale outside the United States and add convenience features to sterilizer.
