Intended 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.

Device Story

Tyvek Sterilization Pouches with Chevron Seal enclose medical devices for ethylene oxide (EO) sterilization. Pouches consist of uncoated high-density polyethylene (Tyvek) backing and clear laminated PET/LDPE or LDPE-EVA film front. Available as self-seal or heat-sealable pouches/tubing. Used in healthcare facilities; operated by clinical staff. Devices inserted and sealed; processed in EOGas 4 Sterilizer (3-hour or 6-hour cycles at 50°C). AN85 EO indicators on pouch exterior change color (yellow-green to blue) to confirm EO exposure. Pouches maintain sterility for 6 months post-processing. Facilitates safe sterilization of surgical instruments, endoscopes, and reusable materials.

Clinical Evidence

Bench testing only. Sterilization efficacy validated using half-dose method, achieving 10^-6 SAL. Package integrity (seal strength, microbial barrier, burst, peel) verified per ISO 11607-1 and ASTM standards. Shelf life studies confirmed 6-month sterility maintenance post-processing. Biocompatibility testing passed.

### 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.

## 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.

| Ethylene Oxide | Temperature | Relative<br>Humidity | Ethylene Oxide<br>Exposure Time | Total Cycle Time |
|----------------|-------------|----------------------|---------------------------------|------------------|
| 17.6 g ± 5% | 50°C ± 3°C | 35-90% | 3 hours | 3.5 hours |
| | | | 6 hours | 7 hours |

Table 5-1. Critical sterilization cycle parameters for EOGas 4 Ethylene Oxide Gas Sterilizer

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.

# 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.
