The Andersen B-2270/AN70 Anprolene Sterilizer is a pre-amendment predicate device. It was in commercial distribution and clinical use in the United States prior to May 28, 1976. For the subject device, the material composition of the sterilization bag, the ethylene oxide delivery method, and the sterilization cabinet design of the pre-amendment device were modified. No modifications were made to the technology or intended use. ### Device Description The Anprolene AN75 Ethylene Oxide Gas Sterilizers, model numbers AN75i (AN75.64 and AN75.65), AN75iX (AN75.84 and AN75.85), and AN75J (AN75.74 and AN75.75), are intended to sterilize moisture, temperature, chemical corrosion, or radiation-sensitive reusable medical devices in healthcare facilities. The sterilant is a unit dose of 100% ethylene oxide contained in a cartridge, and the sterilization chamber is a gas-impervious flexible sterilization bag. Each sterilization cycle is monitored using cumulative gas exposure measurement (AN87 Dosimeter), as well as a Bacillus atrophaeus biological indicator (AN2203) inserted into a process challenge device (AN7508.14 Anprolene SteriTest) that is integrated into the sterilizer. ### Indications for Use The Anprolene AN75 Ethylene Oxide Gas Sterilizer is intended for use in hospitals and other human healthcare settings. It is designed to sterilize reusable medical devices that are sensitive to moisture, heat, chemical corrosion, or radiation. The 12 hour cycle at 20-29℃ in the Anprolene AN75 Ethylene Oxide Gas Sterilizer is for surface sterilization of medical devices, including mated surfaces. The critical process parameters for the cycle are summarized in Table 1. Table 1. Critical sterilization cycle parameters in the Anprolene AN75 Ethylene Oxide Gas Sterilizer | EO Amount | Temperature | Relative Humidity | EO Exposure Time | Total Cycle Time | |-------------|-------------------|-------------------|------------------|------------------| | 17.6 g ± 5% | 20-29°C (68-84°F) | 35-70% | 12 hours | 14 hours | {6}------------------------------------------------ Maximum loads of specific materials and devices that have been validated are listed in Table 2.

Load and material types validated in the Anprolene AN75 Ethylene Oxide Gas Sterilizer Reusable medical devices must be aerated following the instructions of device manufacturers and packaging material manufacturers, then released for use after sterilization based on successful inactivation of an EZTest - Gas Biological Indicator in the Anprolene SteriTest process challenge device. # Substantial Equivalence Comparison The Anprolene AN75 Ethylene Oxide Gas Sterilizer is substantially equivalent to the predicate devices: the B-2270/AN70 Anprolene Sterilizer and the EOGas 4 Ethylene Oxide Gas Sterilizer, because all three sterilizers are intended for the same use, designed in a similar way, use similar technology, and perform substantially equivalently. The Anprolene AN75 Ethylene Oxide Gas Sterilizer differs from the predicate B-2270/AN70 Anprolene sterilizer in the use of a sterilization bag that is ethylene oxide impermeable, gas delivery from an ampoule in a cartridge rather than an ampoule in a gas release bag, and a ventilated sterilization cabinet surrounding the sterilization bag. Compared to the predicate EOGas 4 sterilizer, the Anprolene AN75 Ethylene Oxide Gas Sterilizer has a gas exposure of 12 hours at 20-29℃ rather than 3 hours at 50±3℃. Ventilation after sterilization is 2 hours for the subject Anprolene AN75 sterilizer, and 30 minutes for the predicate EOGas 4 sterilizer. These differences raise no issues related to safety or effectiveness of the subject device sterilization cycle. A comparison among the sterilizers is listed in Table 3. {7}------------------------------------------------ Table 3: Comparison among the Anprolene AN75 Ethylene Oxide Gas Sterilizer, the B-2270/AN70 Anprolene Ethylene Oxide Gas Sterilizer, and the EOGas 4 Ethylene Oxide Gas Sterilizer | | Predicate EOGas 4 Sterilizer (K150646) | Predicate B-2270/AN70 Anprolene Sterilizer | Subject Anprolene AN75 Sterilizer | Comparison | |--------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------| | Intended Use | Indoor ethylene oxide sterilizer in a healthcare setting | | | Same | | Indications for Use | Intended for use in hospitals and other human healthcare settings | | | Same | | | Designed to sterilize reusable medical devices that are sensitive to moisture, heat, chemical corrosion, or radiation | | | Same | | | 3 hour EO exposure at $50\pm3$ °C with 0.5 hr mandatory ventilation | 12 hour EO exposure at 20-29°C with 2 hrs mandatory ventilation | | | | | For surface sterilization and sterilization of single-lumen flexible endoscopes | For surface sterilization, including mated surface | | Equivalent | | Design | Ventilated cabinet | Stainless steel container | Ventilated cabinet | Equivalent | | | Unit dose EO in cartridge | Unit dose EO in gas release bag | Unit dose EO in cartridge | | | | Flexible sterilization chamber | | | | | | EO impermeable sterilization bag | Gas-diffusion sterilization bag | EO impermeable sterilization bag | | | Technology | Use EO as sterilant; EPA registered | | | Same | | | Critical parameters: EO concentration, RH, temperature, and time | | | | | Biological Monitoring | EOGas 4 SteriTest | AN80 Steritest | Anprolene SteriTest | Equivalent | | Safety | Verified compliance for electromagnetic compatibility and electrical safety; Human Factors evaluation for safety and effectiveness. | N/A | Verified compliance for electromagnetic compatibility and electrical safety; Human Factors evaluation for safety and effectiveness. | Same | | Performance | Sterilize reusable medical devices as defined in the sterilizer labeling to a SAL of 10-6 with reasonable assurance of safety and effectiveness | Sterilize reusable medical devices as defined in the sterilizer labeling | Sterilize reusable medical devices as defined in the sterilizer labeling to a SAL of 10-6 with reasonable assurance of safety and effectiveness | Equivalent | {8}------------------------------------------------ # Performance Testing The Anprolene AN75 Ethylene Oxide Gas Sterilizer has been validated using applicable tests in the FDA 1993 "Guidance on Premarket Notification [510(k)] Submissions for Sterilizers Intended for Use in Health Care Facilities". The maximum loads of metal, fabric, and plastic devices that may be routinely sterilized in the Anprolene AN75 Ethylene Oxide Gas Sterilizer were defined and validated. Using the 12 hour cycle at 20-29°C, the Anprolene AN75 sterilization system reproducibly and effectively sterilizes 24 lbs of metal instruments with or without mated surfaces, 3.0 lbs of fabric, and 3.5 lbs of plastic devices, achieving a minimum sterility assurance level (SAL) of 10-6. All validated maximum loads were processed without additional devices in the sterilizer. A compatible carrier for EO sterilization (a perforated metal basket) was used to hold the metal and plastic devices, for the convenience of handling relatively large quantities of devices. The validation testing demonstrated that exposure to EO gas under the defined loads and physical parameters achieved a minimum sterility assurance level (SAL) of 10 for surfaces, including mated surfaces. The effectiveness of the sterilization process for the loads was confirmed by successful sterilization in simulated-use testing using instruments with mated surfaces. Process residue analysis showed that after recommended aeration. EO residuals on the most absorbent materials tested in the study met the requirements of AAMI/ANSI/ISO 10993-7. demonstrating that the Anprolene AN75 Ethylene Oxide Gas Sterilizer and its accessories are safe to use if the guidance and instructions are followed. The Anprolene AN75 Ethylene Oxide Gas Sterilizer was tested to verify compliance with requirements for electromagnetic compatibility and electrical safety. Physical performance tests demonstrated that the Anprolene AN75 Ethylene Oxide Gas Sterilizer, gas cartridges, and sterilization bags met their performance specifications. The Anprolene AN75 sterilization system achieved and maintained the cycle specifications for EO concentration, temperature, time, and relative humidity. Both the sterilizer and the accessories consistently operated in accordance with predetermined criteria. The 12 hour cycle at 20-29°C in the Anprolene AN75 Ethylene Oxide Gas Sterilizer was repeatable and reliable under the indicated test load conditions. Shelf Life testing demonstrated that the AN7514 cartridges maintain performance specifications (physical characteristics, released EO amount, EO concentration, and inactivation of biological indicators) throughout the stated shelf life of 5 years, demonstrating reasonable assurance for effectiveness. # Conclusion The Anprolene AN75 Ethylene Oxide Gas Sterilizer is substantially equivalent to the preamendment predicate Andersen B-2270/AN70 Anprolene Sterilizer, and the predicate EOGas 40 Ethylene Oxide Gas Sterilizer (K150646).
