Sterilization Wraps is intended to be used to enclose another medical device that is to be sterilized by a health care provider using:
• Pre-vacuum steam at 270°F/132°C for 4 minutes

Types of medical devices to be sterilized in the pre-vacuum cycle:
General purpose reusable metal and nonmetal devices(No lumen) including devices with stainless steel diffusionrestricted spaces such as forceps and scissors, as well as other general medical instruments having mated surfaces, knurled areas etc.

The size of the Devices to be sterilization Wraps pack and form a closed space. Validated for dry time is 30 minutes for Sterilization Wraps.

Color of wrap: Blue Size of wrap: 48 in x 48 in

The maximum validated weight of load for Sterilization Wraps is 12kg.

The wrap is intended to allow sterilization of the enclosed medical device(s) and also to maintain sterility of the enclosed device(s) until used.

Sterilization Wraps is a 63gsm, latex-free, 3-layer (SMS) non-woven sterile wrap, manufactured with spun-bonded / meltblown polypropylenem. Sterilization Wraps provides a strong barrier which protects against cuts, tears with particularly heavy orthopedic sets. Sterilization Wraps is designed to be implemented as an outer sterilization wrap which can be used in combination with Clinipak choice. Sterilization Wraps is made of polypropylene and blue pigment by non-woven process.

The provided document describes the acceptance criteria and the results of the study for the Sterilization Wraps device (K220133). This is a non-clinical study focused on the physical and biological characteristics of the wrap, rather than a clinical study involving human or AI performance.

Here's a breakdown of the requested information based on the provided text:

Acceptance Criteria and Reported Device Performance

The acceptance criteria are generally established by meeting the requirements of recognized industry standards. The study demonstrates that the proposed device complies with these standards.

Additional Information

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

• The document does not explicitly state numerical sample sizes for each test. Instead, it refers to "test samples" or "subject wrap."
• Data Provenance: Not specified, but generally, these types of non-clinical tests are performed in a laboratory setting. There is no information regarding country of origin for the test data, nor if it's retrospective or prospective.

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

• This is a non-clinical study involving material and biological performance testing (e.g., sterilization effectiveness, physical properties, biocompatibility). It does not involve "experts" establishing a ground truth in the way a clinical diagnostic study would (e.g., radiologists interpreting images). The "ground truth" is established by the technical specifications and performance requirements outlined in the referenced international standards.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

• Not applicable. This is a non-clinical performance study against predetermined technical standards, not a diagnostic accuracy study requiring adjudication of interpretations.

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 is not a study involving human readers, AI assistance, or diagnostic effectiveness.

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

• Not applicable. This device is a physical sterilization wrap, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• The ground truth is based on the requirements and methodologies defined by internationally recognized standards (e.g., ISO, ASTM, AAMI, AATCC, USP) for sterilization wraps and medical device packaging. Compliance with these standards serves as the "ground truth" for acceptable performance.

8. The sample size for the training set:

• Not applicable. This is a physical product, not an AI/machine learning model that requires a training set.

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

• Not applicable, as there is no training set for this type of device.
