The Fort Defiance Industries FRONT-LINE Field Sterilizer (FL135) is an autoclave designed for sterilizing heat- and moisture-stable medical, dental, and surgical materials, including wrapped, solid, porous, and hollow items (e.g., dental handpieces, suction pipes) in healthcare facilities.

Device Description

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.

AI/ML Overview

The provided text describes the 510(k) summary for the Fort Defiance Industries FRONT-LINE Field Sterilizer (FL135) and its modifications. The key changes involve reducing the dry times for wrapped instruments, textiles, and handpieces cycles. The study provided focuses on the sterilizer's performance and safety and is not an AI/ML-driven device. Therefore, many of the requested criteria related to AI/ML studies (such as MRMC studies, number of experts for ground truth, sample sizes for training sets, etc.) are not applicable to this submission.

The acceptance criteria and performance data are primarily based on the sterilizer's ability to achieve and maintain sterility, as well as its moisture retention characteristics, according to the AAMI ST55:2016 standard.

Here's a breakdown of the available information:

1. A table of acceptance criteria and the reported device performance

The acceptance criteria are derived from ANSI/AAMI ST55:2016. The reported device performance is indicated by "PASS" for each test.

Acceptance Criteria (from AAMI ST55:2016 Requirements)Reported Device Performance
Sterilizer Temperature Control & Pressure Measurement 4.4.3 -0/+6°F temp controlPASS (5.4.3 - Temperature instrumented chamber tests to confirm steady state temperature control range and documentation of cold point)
Software Verification and Validation 4.4.7 Sterilizer fault conditionsPASS (5.4.7 - Verified by inspection, TP-5110: Sterilizer Fault Conditions, TP-5120: General Functions, TP-5130: Full Cycle Verification)
Biological Performance - Wrapped Instrument 4.5 Biological performance of sterilizersPASS (5.5.4 Biological performance with wrapped instruments)
Moisture Retention - Textiles 4.7 Moisture RetentionPASS (5.7.1 Textile test packs)
Moisture Retention - Wrapped Instrument 4.7 Moisture RetentionPASS (5.7.2 Wrapped Instr. Test trays)
Moisture Retention - Pouches 4.7 Moisture RetentionPASS (5.7.3 Paper-plastic peel pouches)
Safety - Electrical SafetyPASS (3rd Party test protocol per IEC 61010-1 Edition 3.1 2017-01)
Safety - EMC/EMIPASS (3rd Party test protocol per IEC 61326-1:2020)

2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

  • Sample Size for Test Set: The document mentions "3 successive cycles at half the programmed exposure time" for the overkill method to guarantee a sterility assurance level (SAL) of at least 10^-6. It also mentions validation studies were conducted. However, the exact sample sizes for each specific test (e.g., number of textile packs, wrapped instruments, or handpieces tested) are not explicitly stated in the provided summary.
  • Data Provenance: The studies were conducted by Fort Defiance Industries LLC which is based in Loudon, Tennessee, USA. The studies appear to be prospective validation studies performed to support the 510(k) submission for the device modifications.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

  • Not Applicable. This is a hardware medical device (steam sterilizer) and the ground truth is established through physical and biological indicators, not human expert consensus on interpretations of images or data. The validation is against established engineering and sterilization standards (ANSI/AAMI ST55:2016).

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

  • Not Applicable. As above, this is not an AI/ML or diagnostic study requiring human expert adjudication. The performance is objectively measured against physical and biological parameters.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

  • Not Applicable. This is not an AI/ML device, and no human reader comparative effectiveness studies were performed or are relevant.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

  • Not Applicable. This is not an AI/ML algorithm. The performance is the standalone performance of the sterilizer itself. The summary evaluates the device's ability to sterilize and dry items on its own, based on programmed cycles.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

  • The ground truth for sterilizer performance is based on established industry standards and scientific principles of sterilization. This includes:
    • Biological Indicators: Used in the "overkill method" to demonstrate a Sterility Assurance Level (SAL) of at least 10^-6. This typically involves challenging the sterilizer with a high concentration of resistant microorganisms, and "ground truth" is established by their survival or inactivation.
    • Physical Parameters: Temperature and pressure measurements throughout the cycle, as defined by ANSI/AAMI ST55:2016 (e.g., -0/+6°F temp control).
    • Moisture Retention: Empirical measurements of water remaining on processed items, compared against defined limits in the AAMI standard.

8. The sample size for the training set

  • Not Applicable. This device uses pre-programmed cycles based on engineering design and validation against recognized standards, not machine learning models that require a training set.

9. How the ground truth for the training set was established

  • Not Applicable. No training set for an AI/ML model.

Wrapped Instruments/Pouches2506035
270 & 2756030
Handpieces270 & 2756030

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.

4. Design and Materials

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.

న. Technology

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.

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.
