Intended Use

The SYSTEM 1E Liquid Chemical Sterilant Processing System is intended for liquid chemical sterilization of cleaned, immersible, and reusable critical and semi-critical heat-sensitive medical devices in healthcare facilities. The SYSTEM 1E Processor dilutes the S40 Sterilant Concentrate to its use dilution (>1820 mg/L peracetic acid), liquid chemically sterilizes the load during a controlled 6-minute exposure at 45.5 to 60°C, and rinses the load with extensively treated* potable water. After completion of a cycle, critical devices should be used immediately; semi-critical devices should be used immediately or may be handled and stored in a manner similar to that of high level disinfected endoscopes. Critical devices not used immediately should be processed again before use. The SYSTEM 1E Processor uses only S40 Sterilant Concentrate to liquid chemically sterilize medical devices.

Device Story

Automated, self-contained liquid chemical sterilization system; processes immersible, heat-sensitive medical devices (flexible/rigid endoscopes, microsurgical instruments). Input: S40 Sterilant Concentrate (peracetic acid) and EPA potable water. Operation: Processor dilutes sterilant; maintains 45.5–60°C for 6-minute exposure; performs two-stage rinse with UV-irradiated, 0.1-micron filtered water. Output: Sterilized devices; printed cycle documentation. Used in healthcare facilities; operated by clinical staff. Processor monitors cycle parameters (temperature, contact time, sterilant concentration, filter integrity, UV intensity). Provides automated, unalterable processing cycles. Benefits: Enables rapid sterilization of heat-sensitive instruments; ensures consistent, validated sterilization conditions; reduces manual handling of chemical sterilants.

Clinical Evidence

Bench testing only. Efficacy validated via AOAC Official Methods (966.04, 955.17, 955.14, 955.15, 964.02) and EPA virucidal testing. Simulated-use testing demonstrated >6-log10 reduction of Geobacillus stearothermophilus spores. Material compatibility confirmed through 300 cycles for flexible endoscopes and 150 cycles for rigid devices.

Technological Characteristics

Microprocessor-controlled liquid chemical sterilizer. Uses peracetic acid (S40 Sterilant Concentrate). Water treatment: pre-filtration (2.5 micron and 0.1 micron), UV irradiation (>6-log reduction of MS2 virus), and redundant 0.1-micron absolute membrane filtration. Cycle: 6-minute exposure at 45.5–60°C. Connectivity: Printed cycle documentation. Components: Interchangeable processing trays/containers and Quick Connects.

Indications for Use

Indicated for liquid chemical sterilization of cleaned, immersible, reusable critical and semi-critical heat-sensitive medical devices in healthcare facilities.

Regulatory Classification

Identification

#### 2. Predicate Device

SYSTEM 1E Liquid Chemical Sterilant Processing System cleared under K161683

#### 3. Description of Device

The SYSTEM 1E Liquid Chemical Sterilant Processing System is a liquid chemical sterilization system, utilizing peracetic acid to process totally immersible, heat sensitive, flexible and rigid endoscopes and their accessories, and microsurgical instruments. The system consists of the SYSTEM 1E Processor and the S40 Sterilant Concentrate, interchangeable processing trays/containers and Quick Connects. The device was originally cleared under K090036. Five Special 510(k)s were cleared that subsequently made minor modifications to hardware, software, specifications, and labeling. This premarket notification introduces a new processing tray that will accommodate ultrasound endoscopes and other large flexible devices and their associated Quick Connects. Additionally, minor inconsistent statements in the cleared Indications for Use are corrected, and clarification is provided on post-processing handling and storage of critical and semi-critical medical devices.

The SYSTEM 1E Processor is an automated, self-contained device which creates and maintains the conditions necessary for liquid chemical sterilization in 6 minutes. Following processing, the liquid chemically sterilized articles are rinsed with extensively treated water produced by passing EPA potable tap water through pre-filters, an ultraviolet light treatment subsystem, and then through two 0.1 micron filter membranes. The processor, which is computer controlled and continually monitored, provides printed documentation of each cycle.

{5}------------------------------------------------

S40 Sterilant Concentrate is a single use chemical sterilant concentrate developed exclusively for use in the SYSTEM 1E Processor. The active ingredient in S40 Sterilant Concentrate, peracetic acid, is combined with inert ingredients (builders) to form a use dilution which inhibits corrosion of metals, polymers and other materials.

The interchangeable processing trays/containers are made to accommodate a variety of instrument types, models and procedure specific sets. Each container is designed to maintain instruments in appropriate position while specific Quick Connects for the SYSTEM 1E Processor, if required, facilitate delivery of the liquid chemical sterilant use dilution and rinse water to internal channels.

#### 4. Intended Use

The SYSTEM 1E Liquid Chemical Sterilant Processing System is intended for liquid chemical sterilization of cleaned, immersible, and reusable critical and semicritical heat-sensitive medical devices in healthcare facilities.

The SYSTEM 1E Processor dilutes the S40 Sterilant Concentrate to its use dilution (>1820 mg/L peracetic acid), liquid chemically sterilizes the load during a controlled 6-minute exposure at 45.5 to 60°C, and rinses the load with extensively treated* potable water. After completion of a cycle, critical devices should be used immediately; semi-critical devices should be used immediately or may be handled and stored in a manner similar to that of high level disinfected endoscopes. Critical devices not used immediately should be processed again before use.

The SYSTEM 1E Processor uses only S40 Sterilant Concentrate to liquid chemically sterilize medical devices.

#### ડ. Description of Technological Similarities and Differences

The SYSTEM 1E Liquid Chemical Sterilant Processing System is the same as the predicate device except for the specific modification described in this submission. The differences between the proposed and predicate devices are limited to the addition of a new Ultrasound Processing Tray and the Quick Connects that enable the processing of large flexible ultrasound devices and labeling updates to correct errors and provide clarity to users and these proposed changes raise no new concerns of safety and effectiveness when compared to the predicate device.
