The provided document is a 510(k) summary for a guidewire device and specifically states that no clinical tests were performed (Section 8. Clinical Test: "It is not applicable"). Therefore, there is no study described that involves AI or human readers for diagnostic purposes. The acceptance criteria and testing detailed relate to the physical and biocompatibility performance of the guidewire itself.

Based on the provided text, here's a breakdown of the requested information, focusing on the non-clinical performance and a clear indication where information is not available or applicable:

1. Table of Acceptance Criteria and Reported Device Performance

The document states that for each performance test, "The predetermined acceptance criteria was met." Specific numerical thresholds for these criteria are not provided in this summary.

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

The document does not specify the exact sample sizes for each test in the acceptance criteria, nor does it detail the provenance of any data beyond indicating "in-house standard" for some tests. It mentions testing on "non-aged and aged to 3 years sample," implying samples were physical guidewire units. This is a medical device, not a diagnostic AI product, so "data provenance" as it relates to patient data is not applicable here.

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

Not applicable. This device is a physical medical instrument (guidewire) and not a diagnostic tool requiring expert interpretation or ground truth establishment in the traditional sense of an AI study.

4. Adjudication method for the test set

Not applicable. There is no human interpretation or adjudication described for the performance tests of the guidewire.

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

No. The document explicitly states "Clinical Test: It is not applicable." This is a guidewire, not an AI-assisted diagnostic tool.

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

No. This is a guidewire, not an algorithm or AI product.

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

For the physical and biological tests of the guidewire, the "ground truth" or reference points are defined by the standards themselves (e.g., ISO, ASTM, FDA guidance, USP) and "in-house" specifications. These standards provide the objective criteria against which the device performance is measured.

8. The sample size for the training set

Not applicable. This is a physical medical device. There is no AI model requiring a training set.

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

Not applicable. There is no AI model requiring a training set or ground truth in that context.

The provided document is a 510(k) premarket notification summary for a medical device (KDL Introducer Set). It outlines the device's technical specifications, intended use, and comparison to a predicate device. However, this document describes a Class II medical device (a catheter introducer) and not an AI/ML-driven device. Therefore, the information typically requested in your prompt regarding acceptance criteria and studies for AI/ML device performance (such as sample size for test sets, data provenance, expert ground truth adjudication, MRMC studies, standalone algorithm performance, training set details, etc.) is not applicable to this type of traditional medical device.

Instead, the document details non-clinical performance testing and biocompatibility testing to demonstrate substantial equivalence to a predicate device.

Here's a breakdown of the relevant information provided in the document concerning how the device meets acceptance criteria:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't present a single table with "acceptance criteria" and "reported device performance" in the way one might for an AI/ML diagnostic output (e.g., sensitivity, specificity thresholds). Instead, it lists various "Testing item" and "Reference Standard/Guidance" for different components of the Introducer Set. The document then states:

"All sample tested met the standard applicable to each test." and "Base on the result of the performance and biocompatibility testing, the proposed device, Introducer Set, met all the predetermined acceptance criteria of design verification and validation as specified by applicable standards, guidance, and test protocols."

Here's a re-composition of this information into a table format based on the supplied text:

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

• Sample Size: The document does not specify the exact sample size for each test. It states "The performance tests were performed on the non-aged and ages to 3 years sample." This implies that samples were tested for immediate performance and also after accelerated aging simulating 3 years of shelf life. Specific lot sizes or number of units tested per parameter are not disclosed in this summary.
• Data Provenance: Not explicitly stated, however, the manufacturer is Shanghai Kindly Medical Instruments Co., Ltd. in Shanghai, China. The testing would have been conducted by or for them, likely in China. The study is a non-clinical performance testing and biocompatibility assessment, rather than a clinical study with patient data.

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 as this is a traditional medical device undergoing physical and biological performance testing, not an AI/ML device relying on interpretation of medical images or data by experts to establish ground truth. The "ground truth" here is defined by the technical specifications and standards (e.g., ISO, ASTM).

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

• This question is not applicable for the same reason as point 3. Testing involves objective measurements against established engineering and biocompatibility standards.

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 as the device is not an AI-driven product nor does it involve human readers interpreting medical cases.

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

• This question is not applicable as the device is not an algorithm.

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

• The "ground truth" for this device is based on engineering specifications, established international standards (ISO, ASTM), and FDA guidance documents for medical devices (specifically catheter introducers and guidewires). For biocompatibility, it's based on standard biological test methods outlined in ISO 10993 and ASTM F756.

8. The sample size for the training set:

• This question is not applicable as this is a manufactured medical device, not an AI/ML model that requires a training set.

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

• This question is not applicable for the same reason as point 8.
