## Indications for Use

The Fort Defiance Industries FRONT-LINE Field Sterilizers are autoclaves designed for sterilizing heat- and moisture-stable medical, dental, and surgical materials, including wrapped and unwrapped, solid, porous, and hollow items (e.g., dental handpieces, suction pipes) in healthcare facilities.

## Device Story

FRONT-LINE Field Sterilizers (FL120, FL135) are tabletop autoclaves for healthcare facilities. Devices use electric resistive heaters to generate steam within a chamber boiler for sterilization. Operation involves Steam Flush Pressure Pulse (SFPP) cycles to purge air, followed by steam exposure and a drying phase. Users interact via a touchscreen controller to select from 10 pre-programmed cycles. Safety features include door interlocks, overtemperature/overpressure protection, and a pressure safety relief valve. Exhaust air passes through a 0.3-micron HEPA filter and heat exchanger for moisture reclamation. The device ensures sterility of medical/dental instruments, supporting clinical infection control workflows.

## Clinical Evidence

Bench testing only. Validation performed per ANSI/AAMI ST55:2016. Testing included sterilization effectiveness (overkill method), biological performance (textiles, wrapped instruments, dental handpieces), moisture retention, and software verification. All tests passed.

## Technological Characteristics

Steam sterilizer with 316L stainless steel chamber and 6061-T6 aluminum door. Uses electric resistive heaters for steam generation. Features touchscreen PLC controller, 0.3-micron HEPA filter, and heat exchanger. Complies with ASME Section VIII Div 1, IEC 61010-1, IEC 61010-2-040, and IEC 61326-1. Dimensions: FL120 (12"x23"), FL135 (13.5"x24").

## Regulatory Identification

A steam sterilizer (autoclave) is a device that is intended for use by a health care provider to sterilize medical products by means of pressurized steam.

#### 2. Predicate Device

K111736, Tuttnauer EZ11 Plus Electronic Tabletop Autoclave, product code FLE, cleared December 8, 2011

#### 3. Description of Device

The Fort Defiance Industries FRONT-LINE Field Sterilizers are autoclaves designed for sterilizing heat- and moisture-stable medical, dental, and surgical materials, including wrapped and unwrapped, solid, porous, and hollow items (e.g., dental handpieces, suction pipes) in healthcare facilities. The devices use electrical resistive heaters to produce steam as the sterilizing agent. The devices adhere to sterilization processes and requirements that are universally accepted sterilization standards for Tabletop Steam Sterilizers. A touchscreen controller is used for monitoring and control of the device.

The devices are equipped with multiple safety features. The door includes a safety locking mechanism and door switch. The door switch does not permit cycle operation unless the door is sealed closed and does not permit the door to be opened until the internal chamber pressure is at atmospheric pressure. Additional safety features include electronic overtemperature and overpressure protection, an independent high temperature cutoff switch, and a pressure safety relief valve for the pressure vessel.

Only United States Food and Drug Administration cleared sterilization accessories should be used with these autoclaves.

#### 4. Design and Materials

The FRONT-LINE Field Sterilizers, models FL120 and FL135, are steam sterilizers composed of a stainless-steel chamber, an aluminum chamber door, electric resistive heaters, a plumbing system with a clean water tank, control system, and an aluminum frame providing a housing for all components. The devices are electronically controlled, and each device includes 10 pre-programmed sterilization cycles. All materials in the sterilization system and plumbing system are deemed acceptable for steam sterilizers.

#### న. Technology

The FRONT-LINE series of autoclaves are steam sterilizers composed of a pressure vessel that utilizes electric resistive heaters to produce the sterilizing agent, steam, from a chamber boiler. The autoclaves contain an electronic control system that automatically initiates programmed Steam Flush Pressure Pulse (SFPP) phases to purge atmospheric air from the chamber followed by a timed steam exposure and drying phase. Exhaust air purged during the dry phase passes through a heat exchanger to condense water vapor and reclaim as much condensate as possible for reuse.

#### 7. Comparison of Technology

The previously cleared device and the FRONT-LINE Field Sterilizers FL120 and FL135 are traditional steam sterilizers of similar chamber size using AAMI approved Steam Flush Pressure Pulse (SFPP) dynamic air removal cycles. The previously cleared device and the FRONT-LINE series sterilizers use electric heaters to generate steam and touchscreen controllers for cycle control. Based on the information provided below, there are negligible differences noted between the FRONT-LINE series and the predicate with regards to chamber size, cycle parameters, and configuration of steam generation. The differences do not affect safety or effectiveness of the new devices compared to the predicate. Table 1 provides a summary of performance and safety characteristics of the proposed new devices and the predicate.

#### 8. Summary of Non-Clinical Testing

Fort Defiance Industries conducted validation studies in accordance with AAMI/ANSI ST55:2016 (FDA Recognition Number 14-518). Design outputs and testing demonstrate that the FRONT-LINE Models FL120 and FL135 autoclaves meet all aspects of the standard.

Performance effectiveness of the sterilizer cycles and exposure time recommendations were demonstrated by the overkill method by passing 3 successive cycles at half the programmed exposure time to guarantee a sterility assurance level (SAL) of at least 10 to probability of survival. Fort Defiance Industries validates its sterilization cycles using recommended practices, standards and guidelines developed by independent organizations such as the Association for the Advancement of Medical Instrumentation (AAMI). The Fort Defiance Industries FRONT-LINE Field Sterilizers FL120 and FL135 have been validated to meet the requirements of ANSI/AAMI ST55:2016, Tabletop Steam Sterilizers (FDA Recognition Number 14-518). Table 2 summarizes FRONT-LINE Field Sterilizer FL120 and FL135 effectiveness testing and results performed by Fort Defiance Industries.
