The device description and performance studies focus on the physical properties and sterilization efficacy of the pouches, with no mention of AI or ML.
No
The device is a sterilization pouch, intended to enclose medical devices for sterilization and maintain their sterility. It does not exert a therapeutic effect on the body.
No
Explanation: The device, Tyvek Sterilization Pouches, is used to enclose medical devices for sterilization and maintain their sterility, not to diagnose medical conditions.
No
The device description clearly indicates it is a physical product (pouches made of Tyvek and film) used to enclose medical devices for sterilization. There is no mention of software components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to enclose medical devices for sterilization in a healthcare facility. This is a process related to preparing medical devices for use, not for performing diagnostic tests on biological samples.
- Device Description: The description focuses on the materials and function of the pouch for sterilization and maintaining sterility. It does not mention any components or processes related to analyzing biological samples or providing diagnostic information.
- Lack of IVD Indicators: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic results.
The device is a sterilization packaging material, which falls under a different regulatory category than IVD devices.

Intended Use / Indications for Use
Tyvek Sterilization Pouches with Chevron Seal are intended to enclose medical devices that are to be sterilized in a single pouch configuration at a healthcare facility. They are used in 3-hour and 6-hour gas exposures at 50°C in the EOGas 4 Ethylene Oxide Gas Sterilizer.
Critical process parameters for the cycle are summarized in Table 5-1.
Table 5-1. Critical sterilization cycle parameters for EOGas 4 Ethylene Oxide Gas Sterilizer
Ethylene Oxide: 17.6 g ± 5%
Temperature: 50°C ± 3°C
Relative Humidity: 35-90%
Ethylene Oxide Exposure Time: 3 hours, 6 hours
Total Cycle Time: 3.5 hours, 7 hours
The EOGas 4 Ethylene Oxide Gas Sterilizer 3-hour gas exposure is used for surface sterilization of medical devices, including instruments with diffusion-restricted spaces (hinges or mated surfaces), as well as for the sterilization of endoscopes working length shorter than 1100 mm as specified in the sterilizer labeling.
The EOGas 4 Ethylene Oxide Gas Sterilizer 6-hour gas exposure is used for sterilization of duodenoscopes and colonoscopes with working length longer than 1100 mm as specified in the sterilizer labeling.
After completion of the sterilization process, the pouches maintain sterility of the enclosed medical devices for 6 months.

Device Description
Tyvek Sterilization Pouches with Chevron Seal are constructed from an uncoated Tyvek backing of fine, continuous, high-density polyethylene fibers, with front material consisting of a clear, laminated polyethylene terephthalate / low density polyethylene (LDPE) or LDPE-ethylene-vinyl acetate copolymer film. The pouches are used to enclose medical devices that are to be sterilized by a healthcare provider in 3-hour and 6-hour gas exposures at 50°C in the EOGas 4 Ethylene Oxide Gas Sterilizer. Following manufacturer's instructions, devices are inserted into Tyvek Sterilization Pouches and sealed. The self-seal pouch permits sealing of the pouch without heatsealing equipment, whereas the heat-sealable pouches must be heat sealed prior to the cycle. Andersen Sterilizers' AN85 EO Indicators, when placed on the outside of the sterilization pouches. indicate EO exposure and offer a convenient way to differentiate pouches that have been processed in EO sterilization cycles from unprocessed units. The color of the AN85 EO Indicators changes from yellow-green to blue after exposure to EO. After completion of the sterilization process, the pouches maintain sterility of the enclosed medical devices for 6 months.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing was conducted to demonstrate that Tyvek Sterilization Pouches with Chevron Seal perform as intended to allow sterilization of the enclosed medical devices. Sterilization efficacy testing demonstrated a sterility assurance level of 10-6 using the half dose validation method under worst-case conditions. Tyvek Sterilization Pouches with Chevron Seal also maintain sterility of the enclosed devices as intended. Shelf life studies demonstrated after completion of the EOGas 4 sterilization process, sterility is maintained for 6 months. The performance of Tyvek Sterilization pouches is summarized in Table 5-4.

Summary of Non-Clinical Testing
Performance Testing
Performance testing was conducted to demonstrate that Tyvek Sterilization Pouches with Chevron Seal perform as intended to allow sterilization of the enclosed medical devices. Sterilization efficacy testing demonstrated a sterility assurance level of 10 ° using the half dose validation method under worst-case conditions. Tyvek Sterilization Pouches with Chevron Seal also maintain sterility of the enclosed devices as intended. Shelf life studies demonstrated after completion of the EOGas 4 sterilization process, sterility is maintained for 6 months. The performance of Tyvek Sterilization pouches is summarized in Table 5-4.
