Tyvek Sterilization Pouches with Chevron Seal
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.
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.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document does not explicitly state the specific sample sizes for each test (e.g., number of pouches tested for seal strength, microbial barrier, etc.). It refers to "performance testing" and "studies" but doesn't quantify the number of units/samples used in these tests.
- Data Provenance: The context of the document (FDA 510(k) submission) implies these studies were conducted by the manufacturer, Andersen Sterilizers, Inc., likely in the United States (their address is Haw River, North Carolina). The studies appear to be prospective in nature, designed to demonstrate the safety and effectiveness of the device for the specific new indication (use with Anprolene AN75).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not provided in the document. The studies described are primarily bench tests and performance testing against industry standards (ISO, ASTM) and internal validation. They do not involve expert human interpretation of data in the same way a diagnostic AI device would. "Ground truth" here is established through scientific testing methods (e.g., biological indicator inactivation for sterility, physical property measurements for package integrity).
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This is not applicable as the evaluation of this device is based on objective physical and microbiological test results, not on human interpretation or consensus. Therefore, no adjudication method was used or needed.
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 device is a sterilization pouch, not an AI or diagnostic imaging device. Therefore, MRMC studies involving human readers are not relevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a medical device product, not a software algorithm. The "performance" described is purely the physical and biological efficacy of the pouch itself in the sterilization process, independent of human interpretation or automated algorithms.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The ground truth for this device's performance is established through objective scientific measurements and standardized testing methodologies, including:
- Microbiological testing: Such as microbial aerosol challenge tests and biological indicator inactivation assays to demonstrate sterility assurance levels.
- Physical property testing: Measurements of seal strength, burst strength, and peel open characteristics to assess package integrity.
- Chemical/Material analysis: To confirm material compatibility and biocompatibility against established standards (e.g., ISO 11607-1).
- Time-based stability testing: To demonstrate shelf life and maintenance of sterility over time.
8. The sample size for the training set
Not applicable. This device is a physical product (sterilization pouch), not a machine learning model. Therefore, there is no "training set" in the context of AI/ML development.
9. How the ground truth for the training set was established
Not applicable for the same reason as point 8.
