This document discusses the FDA clearance for the SafePath Suturing System, which includes silk, polyamide (nylon), and polypropylene sutures. However, the provided text does not contain information about a study based on AI/ML. All the performance criteria and testing mentioned relate to the physical and biological properties of the sutures and the suturing system, not to an AI component.

Therefore, I cannot answer your request with the specific details about acceptance criteria and studies related to AI/ML performance, sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, or standalone algorithm performance.

The document highlights the following non-clinical performance criteria and testing for the sutures:

1. A table of acceptance criteria and the reported device performance:

2. Sample size used for the test set and the data provenance: Not applicable as this is a non-AI/ML device. The testing was physical and biological, not based on data sets.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable as this is a non-AI/ML device. Ground truth as typically understood in AI/ML is not relevant here.

4. Adjudication method for the test set: Not applicable as this is a non-AI/ML device.

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 as this is a non-AI/ML device.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable as this is a non-AI/ML device.

7. The type of ground truth used: For physical testing, ground truth would be established by the specifications of the USP standards. For biocompatibility, it's about meeting pre-defined safety thresholds as per recognized standards (e.g., ISO 10993).

8. The sample size for the training set: Not applicable as this is a non-AI/ML device.

9. How the ground truth for the training set was established: Not applicable as this is a non-AI/ML device.

The study described is a non-clinical performance testing study that evaluated the physical and biocompatibility characteristics of the sutures and the suturing system. The conclusions state that the device met or exceeded USP criteria for physical properties and met the test criteria for a battery of biocompatibility evaluations. The safety evaluation for the nylon and polypropylene sutures leveraged information from a previously cleared device (K180701) and used identical raw materials, packaging, and sterilization conditions as the predicate devices.
