#### 2. Predicate Device
K183410 AMSCO 600 Steam Sterilizer
### 3. Description of Device
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
{6}------------------------------------------------

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.
