MSI S-500L RF Generator
This 510(k) submission (K041980) for the MSI S-500L RF Generator provides limited information regarding specific acceptance criteria and study details. The document focuses on demonstrating substantial equivalence to a predicate device through general performance testing rather than providing detailed quantitative acceptance criteria and a standalone clinical study report.
Based on the provided text, here's what can be extracted and what is not available:
1. Table of Acceptance Criteria and Reported Device Performance
The submission states, "Performance testing was done to validate its intended use." However, it does not provide a specific table of acceptance criteria or quantitative performance metrics for the MSI S-500L RF Generator. The evaluation primarily relies on comparison to a predicate device.
2. Sample size used for the test set and the data provenance
The document does not specify a "test set" in the context of an AI/algorithm-based device for which this information would typically be relevant. This is an electrosurgical generator, and "performance testing" usually refers to bench testing, electrical safety, electromagnetic compatibility, and functional verification, not clinical data sets in the AI sense.
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 not an AI/algorithm-based device and no clinical "ground truth" establishment by experts is described in the provided text.
4. Adjudication method for the test set
Not applicable.
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 an AI-assisted device for human readers.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not applicable. The "ground truth" for an electrosurgical generator's performance would likely be based on established engineering standards, electrical performance specifications, and safety benchmarks, not clinical ground truth in the context of imaging or diagnostics.
8. The sample size for the training set
Not applicable. This is not an AI/machine learning device that would require a training set.
9. How the ground truth for the training set was established
Not applicable.
Summary of available information:
- Acceptance Criteria & Performance: Not explicitly detailed in quantitative terms. The submission states that "Performance testing was done to validate its intended use" and that "The comparison and performance testing results in this 510(k) notification shows MSI S-500L RF Generator is substantially equivalent to predicate device and is safe and effective in its intended use." This implies that the device's performance met the general expectations for such a device, in line with its predicate.
- Study Type: No large-scale clinical study with a "test set" in the typical sense of AI/diagnostic device evaluation is described. The focus is on demonstrating substantial equivalence to a predicate device (MSI S-500 RF Generator K033888) through engineering and functional performance testing.
- Device Type: Electrosurgical Generator, not an AI/ML-based device. Therefore, many of the requested criteria (test set, ground truth, experts, MRMC studies, training set) typically apply to AI algorithms or diagnostic devices and are not relevant or addressed in this document.
