2. Sample size used for the test set and the data provenance

The document does not specify the exact sample sizes used for each of the non-clinical tests. It only states that the tests were conducted and "all results can meet standards requirements" or "Passed".

The data provenance is not explicitly stated in terms of country of origin or whether it's retrospective or prospective for each specific test. However, the submitter is "Wuhan Zonsen Medical Products Co., Ltd." located in Wuhan, Hubei, China, which implies the testing likely occurred in China.


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

This information is not applicable as the device is a medical accessory (sterilization wrap) and the validation involves non-clinical laboratory and performance testing, not expert interpretation of medical images or data requiring ground truth establishment by medical experts. The "ground truth" for this device's performance is established by meeting the specified international and national standards for physical properties, sterilization efficacy, and biocompatibility.


4. Adjudication method for the test set

This information is not applicable for the type of testing performed for this device. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies involving multiple readers for diagnostic accuracy, which is not relevant here.


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

This information is not applicable. The device is a sterilization wrap, not an AI-powered diagnostic tool. Therefore, MRMC studies and human reader improvement with AI assistance are not relevant to its evaluation.


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

This information is not applicable. As stated above, this is a physical medical accessory, not an algorithm or software device.


7. The type of ground truth used

The "ground truth" for this device's performance is based on established international and national standards for medical device physical properties, biocompatibility, and sterilization process validation (e.g., ASTM, AATCC, ISO standards). The "truth" is whether the device's measured properties and performance meet the predefined thresholds set by these standards.


8. The sample size for the training set

This information is not applicable. This is a physical medical device that undergoes manufacturing and quality control testing, not a machine learning model that requires a training set.


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

This information is not applicable for the same reason as point 8.

The design and technological characteristics of the Sterilization wrap is similar to the predicate chosen. There are minor differences between the devices including Indication for use (sterilization parameter). Size and color. Maximum Recommended Wrapped Package Content Weights,

Note 1 : Indication for use (sterilization parameter)

The proposed device and the predicate device have same sterilizaiton method application, including Pre-vacuum Steam or 100% Ethylene Oxide (EO) sterilization. For those two devices, parameter recommend are different. However, the proposed device has been conducted verification in accordance with ISO11135 and ISO 17665, performance test has been done before and after sterilizaiton, all results can meet standards requirements. Therefore, there are no different questions of safety and effectiveness questions pertaining to performance of the proposed device.

Note 2: Size and color

The proposed device and the predicate device have same dimention, but they are differences in color. However, the proposed device meets the requirements of the standard ISO 10993-5, articles after the steam and EO sterilized were used for the biocompatibility validation testing. Test result shows that the device has non-cytotoxicity. Therefore, the different technological specifications of the proposed device do not raise different questions of safety.

Note 3 Maximum Recommended Wrapped Package Content Weights

Although the maximum recommended wrap package loading are different from the predicate device,the proposed device has been conducted verification in accordance with ISO11135 and ISO 17665, Types of medical devices to be sterilized in the Pre-Vacuum 12/17

Steam Sterilization and Ethylene Oxide Sterilization including general purpose nonlumened reusable metal and nonmetal devices including devices with stainless steel diffusionr estricted spaces such as the hinged portion of forceps and scissors, as well as other general medical instruments etc. All models validated for both sterilization methods with stainless steel as part of the load, which with a maximum weight of each types, range from 21bs to 9lbs, which dependent on each model's size.

Performance test has been done before and after sterilizaiton, all results can meet standards requirements. There are no different questions of safety and effectiveness questions pertaining to performance of the proposed device.

Note 4 Performance test

Both the predicate device and the proposed device has been tested including. Size and Gram weight, Bacterial Filtration Efficiency (BFE), Hydrostatic Pressure, Tensile Strength, Air Permeability, Bursting Strength, Tearing Strength, Lint Generation, Result shows that there are no different questions of safety and effectiveness questions related to performance.

Based on above analysis mentioned above, we can conclude that subject device substantial equivalence with the predicate device.
