Device Description
This change to the FRONT-LINE Field Sterilizer, model FL135, reduces the dry times of the wrapped instrument, textiles, and handpieces cycles from the original dry times to the following new dry times.
| Model | Cycle | Exposure Temperature (°F) | Original Dry Time (mins) | New Dry Time (mins) |
|---|---|---|---|---|
| FL135 | Immediate Use Steam Sterilization (IUSS) | 270 & 275 | 0 | 0 |
| Textiles | 250, 270, & 275 | 60 | 15 | |
| Wrapped Instruments/Pouches | 250 | 60 | 35 | |
| 270 & 275 | 60 | 30 | ||
| Handpieces | 270 & 275 | 60 | 30 |
To allow for the reduction in dry time, the dry rate of the sterilizer was increased by the following changes: (1) added a surface heater on the outside of the chamber to increase heat delivered to the chamber and load, (2) replaced the existing chamber load rack with an improved rack that allows for better heat and mass transfer, (3) implemented a new valve control scheme to improve condensate drainage and air flow during drying, and (4) increased the speed of the air pump to increase airflow through the chamber during drying. FDA consensus standard, AAMI ST55:2016, was referenced to validate dry performance of the predicate and new device. Acceptance criteria were also derived from the above standard.
The Fort Defiance Industries FRONT-LINE Field Sterilizer, model FL135, is an autoclave 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 device uses electrical resistive heaters to produce steam as the sterilizing agent. The device adheres 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 device is 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 and does not permit the door to be opened until the chamber gauge pressure is near zero. Additional safety features include electronic overtemperature and overpressure protection, independent thermal cutoffs, and a pressure safety relief valve for the chamber.
Only United States Food and Drug Administration cleared sterilization accessories should be used with this autoclave.
The FRONT-LINE Field Sterilizer, model FL135, is a steam sterilizer 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 device is electronically controlled and includes 10 preprogrammed sterilization cycles. All materials in the sterilization system and plumbing system are deemed acceptable for steam sterilizers.
The FRONT-LINE FL135 autoclave is a steam sterilizer composed of a pressure vessel that utilizes electric resistive heaters to produce the sterilizing agent, steam, from a chamber boiler. The autoclave contains an electronic control system that automatically initiates programmed Steam Flush Pressure Pulse (SFPP) phases to purge atmospheric air from the chamber followed by a temperature-controlled, timed steam exposure. A final drying phase, assisted by chamber internal and external heaters, completes the sterilization cycle. 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.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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 Model FL135 sterilizer meets all requirements 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 10t6 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 FL135 Sterilizer has been validated to meet the requirements of ANSI/AAMI ST55:2016, Tabletop Steam Sterilizers (FDA Recognition Number 14-518).

7. Comparison of Technology
The previously cleared device and the FRONT-LINE Field Sterilizer model 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 new FL135 sterilizer 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 new FL135 and the predicate with regards to chamber size, cycle parameters, and configuration of steam generation. The differences do not affect the safety or effectiveness of the new device compared to the predicate. Table 1 provides a summary of performance and safety characteristics of the proposed new device and the predicate.

8. Summarv 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 Model FL135 sterilizer meets all requirements 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 10t6 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 FL135 Sterilizer has been validated to meet the requirements of ANSI/AAMI ST55:2016, Tabletop Steam Sterilizers (FDA Recognition Number 14-518). Table 2 summarizes the FL135 effectiveness testing and results performed by Fort Defiance Industries.
