| Gene Mutation | There was no significant difference in the TFT-resistant mutant frequency between the test article | The device passed, implying no significant difference. |
| Implantation | No lesion at the implantation site. The irritation score is less than 1.0. | The device passed, implying no lesion and irritation score less than 1.0. |
| Hemolysis | Hemolytic index is less than 2% | The device passed, implying hemolytic index less than 2%. |
| Seal Strength | Complies with ASTM F88/F88M-15 | "The test results demonstrated that the subject device complies with the following standards" (including ASTM F88/F88M-15). |
| Detecting Seal Leaks | Complies with ASTM F1929-15 | "The test results demonstrated that the subject device complies with the following standards" (including ASTM F1929-15). |
| Hemolytic Properties | Complies with ASTM F756-17 | "The test results demonstrated that the subject device complies with the following standards" (including ASTM F756-17). |
| EO Sterilization Residuals | Complies with ISO 10993-7:2008 | "The test results demonstrated that the subject device complies with the following standards" (including ISO 10993-7:2008). |
| Penetration Testing of Needles | Complies with ASTM F3014-14 | "The test results demonstrated that the subject device complies with the following standards" (including ASTM F3014-14). |
| Bend Testing of Needles | Complies with ASTM F1874-98 | "The test results demonstrated that the subject device complies with the following standards" (including ASTM F1874-98). |
2. Sample size used for the test set and the data provenance
The document does not specify the sample sizes for any of the non-clinical tests mentioned.
The data provenance is also not specified, as these are bench tests and biological evaluations, not human data. It is implied these tests were conducted by the manufacturer or a contracted lab to meet international standards.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This question is not applicable to the provided information. The tests conducted are non-clinical (bench testing, biocompatibility). There is no "test set" requiring expert ground truth establishment in the context of diagnostic performance or clinical outcomes. The "ground truth" for these tests comes from adherence to established scientific and regulatory standards (e.g., USP, ISO, ASTM).
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This question is not applicable. Adjudication methods like 2+1 or 3+1 are used in clinical studies or diagnostic performance evaluations involving human interpretation. The reported tests are non-clinical lab tests and biocompatibility assessments, where results are typically objective measurements or observations against predefined criteria.
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 question is not applicable. The device is a surgical suture, not an AI-powered diagnostic tool. No MRMC study or AI assistance is mentioned or relevant to this device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This question is not applicable. The device is a surgical suture, not an algorithm or AI system.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for the non-clinical tests is established by adherence to recognized international standards and pharmacopeial monographs. For example:
- **USP , , **: These are pharmacopeial standards defining requirements for suture diameter, needle attachment, and tensile strength.
- ISO 10993 series: These are international standards for the biological evaluation of medical devices, covering aspects like cytotoxicity, sensitization, systemic toxicity, genotoxicity, implantation, and hemolysis.
- ASTM standards: These are industrial standards covering material properties and packaging (e.g., seal strength, dye penetration, needle bend/penetration).
The ground truth is based on the objective criteria and methodologies outlined in these standards.
8. The sample size for the training set
This question is not applicable. There is no "training set" as this is not a machine learning or AI device. The submission focuses on verifying the physical and biological characteristics of a mechanical device against established standards.
9. How the ground truth for the training set was established
This question is not applicable, as there is no training set for this device.
