The provided text is a 510(k) summary for the Resolution 360 Clip, a medical device. It describes the device, its indications for use, and a comparison to a predicate device. However, it does not contain detailed information about specific acceptance criteria, study designs with sample sizes, expert qualifications, or adjudication methods for evaluating device performance against numerical thresholds.
The "Performance Data" section mentions that "bench tests were performed" and that "The testing performed demonstrated that the proposed and predicate delivery systems are equivalent." This is a qualitative statement about equivalence based on bench testing, not a detailed report of quantitative acceptance criteria and results.
Therefore, I cannot fulfill all parts of your request with the provided input. I will extract what information is present and explicitly state what is missing.
Here's an analysis of the provided text in relation to your request:
1. A table of acceptance criteria and the reported device performance
This information is not provided in the document. The document states that "bench tests were performed on the Resolution™ 360 Clip" and lists the types of tests (e.g., Clip Assembly Repeated Open/Close, Retention Force, Torque, Rotation, etc.). It then concludes, "The testing performed demonstrated that the proposed and predicate delivery systems are equivalent." However, it does not provide specific acceptance criteria (e.g., "Clip must withstand X cycles" or "Retention Force must be Y N") nor specific numerical performance results for these criteria.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided. The document mentions "bench tests" but does not specify sample sizes for these tests, nor the data provenance (e.g., country, retrospective/prospective).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not applicable/provided. The performance data discussed are bench tests of mechanical and material properties, not clinical studies requiring expert ground truth assessment.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not applicable/provided. Adjudication methods are relevant for clinical studies or evaluations where human judgment on image interpretation or clinical outcomes is involved. The "Performance Data" describes bench testing.
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/provided. The device is a "hemostatic metal clip" used for endoscopic procedures, not an AI-based diagnostic tool. Therefore, an MRMC study related to human readers improving with AI assistance would not be relevant.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
This information is not applicable/provided. This question applies to AI algorithms. The Resolution 360 Clip is a mechanical medical device, not an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
This information is not applicable. For the bench tests described, the "ground truth" would be the engineering specifications and established test methods, not clinical ground truths like pathology or expert consensus.
8. The sample size for the training set
This information is not applicable/provided. "Training set" is relevant for machine learning/AI models. The device is a physical medical device.
9. How the ground truth for the training set was established
This information is not applicable/provided. As above, this question applies to AI models.

Clinical Effectiveness: Stent Anchoring | Resolution Clips should significantly reduce stent migration compared to non-clipped stents when affixing fully covered esophageal self-expanding metal stents (SEMSs). | Study by Vanbiervliet G et al. (2012): - Stent migration was significantly less (p=0.003) when Resolution Clips were used to anchor stents (13%) compared to non-anchored stents (57%). - This met the acceptance criteria, demonstrating the effectiveness of the device in reducing stent migration. |
Clinical Effectiveness: Hemostasis (Prophylactic Clipping) | Prophylactic clip closure for post-polypectomy defects should significantly reduce the risk of delayed bleeding. | Study by Liaquat, H et al. (2013): - Multivariate analysis indicated that non-clipped lesions were 6 times more likely to have a delayed bleed (95% CI, 2.0-18.5; p=0.002) than fully clipped lesions. - Partially clipped lesions were not significantly (p=0.17) more likely to have delayed bleeding compared with fully clipped lesions. - Fisher Exact test comparing prophylactically clipped (complete and partial) to non-clipped defects showed a statistically lower rate of delayed bleeding in the Resolution Clip group (2.5%) compared to the non-clip group (9.7%) (p=0.006). - These results met the acceptance criteria, supporting the safety and effectiveness of prophylactic clipping in reducing delayed post-polypectomy hemorrhage. |
Safety (General) | Absence of complications in clinical use. | Study by Vanbiervliet G et al. (2012): - No complications were observed in either the clipped or non-clipped groups for stent anchoring. Study by Liaquat, H et al. (2013): - The study's findings regarding reduced delayed bleeding also implicitly support the safety of the device for this indication. - These findings support the safety profile of the device in clinical use. |
