The Radical the Dude 8F Guide Catheter is indicated for the introduction of intravascular catheters into the peripheral, coronary, and neuro vasculature.

The Radical the Dude 8F Guide Catheter (Dude 8F Catheter) is an 8 French (Fr) guide catheter designed to aid the physician in accessing the target vasculature during interventional procedures. The Dude 8F Catheter has a usable length between 80 cm and 110 cm, and an outer diameter (OD) size designation of 8 Fr. The Dude 8F Catheter has variable stiffness along its length, incorporating hybrid ribbon technologies to maintain stability and vary stiffness along the device length. The distal portion of the Dude 8F Catheter has a hydrophilic coating. The Dude 8F Catheter is packaged with a rotating hemostasis valve (RHV) and a peel-away sheath.

The provided FDA 510(k) summary (K243577) describes a medical device, the Radical the Dude 8F Guide Catheter, and its substantial equivalence to a predicate device. However, this document does not describe a study involving AI or software performance evaluation with human-in-the-loop scenarios.

Therefore, most of the questions regarding acceptance criteria, study details, sample sizes, expert involvement, and ground truth establishment, which are typically relevant for assessing the performance of AI/software medical devices, cannot be answered based on the provided text.

The 510(k) pertains to a physical catheter device and details traditional bench testing and biocompatibility assessments to establish substantial equivalence with a previously cleared device.

Based on the provided document, here's what can be extracted, and where limitations exist:

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

   The document provides a summary of "Nonclinical Performance Testing" (Bench Testing and Biocompatibility). The acceptance "criteria" are implied by the "Pass" result for each test.

   Table of Acceptance Criteria and Reported Device Performance

2. Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

   • The document describes bench testing and biocompatibility testing. Specific sample sizes for each bench test are not specified in this summary.
   • For the "Thrombogenicity in Canine Model", it used an in vivo canine test, implying an animal study. The exact number of animals or the test setup details are not provided in this summary.
   • There is no mention of "test sets" in the context of clinical data or patient data, as this is a device for physical performance and biocompatibility.

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)

   • Not applicable. The tests are physical or chemical evaluations (e.g., visual inspection, dimensional inspection, tensile strength, PTT). "Ground truth" in the context of expert review for diagnostic accuracy is not relevant here.

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

   • Not applicable. This is not a study requiring adjudication of expert opinions for a test set.

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. An MRMC study was not done, as this is neither an AI device nor does it involve human readers interpreting images.

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

   • No. This is not an algorithm or AI device.

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

   • For bench testing, the "ground truth" is established by adherence to engineering specifications, relevant ISO standards (e.g., ISO 10555-1), and comparison to the predicate/reference device's performance. For biocompatibility, it's based on standard biological evaluation methods and comparison to controls or reference devices.

8. The sample size for the training set

   • Not applicable. This is not an AI/ML device employing a training set.

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

   • Not applicable. There is no training set for this device.

The Radical the Dude 7F Guide Catheter is indicated for the intravascular catheters into the peripheral, coronary, and neuro vasculature.

The Radical the Dude 7F Guide Catheter (Dude 7F Catheter) is a 7 French (Fr) guide catheter designed to aid the physician in accessing the target vasculature during interventional procedures. The Dude 7F Catheter has a usable length between 95 cm and 115 cm, and an outer diameter (OD) size designation of 7 Fr. The Dude 7F Catheter has variable stiffness along its length, incorporating hybrid ribbon technologies to maintain stability and vary stiffness along the device length. The distal portion of the Dude 7F Catheter has a hydrophilic coating. The Dude 7F Catheter is packaged with a rotating hemostasis valve (RHV) and a peel-away sheath.

The document provided is a 510(k) Summary for the Radical the Dude 7F Guide Catheter. It describes the device, its intended use, and a comparison to a predicate device to demonstrate substantial equivalence. This document does NOT describe the acceptance criteria and study for an AI/ML powered device.

The Radical the Dude 7F Guide Catheter is a medical device, specifically a guide catheter, and the submitted information pertains to its regulatory clearance as a physical medical device, not an AI/ML software device. As such, the information requested regarding AI/ML device performance (like test set sample size, expert qualifications, adjudication methods, MRMC studies, standalone performance, ground truth establishment, and training set details) is not applicable or present in this document.

The document mainly focuses on:

• Bench Testing: Mechanical and material property tests to ensure the device meets engineering specifications and is safe for its intended use.
• Biocompatibility Testing: To ensure the materials used in the device are safe for contact with the human body.
• Sterilization: Validation of the sterilization process.
• Shelf Life and Packaging: Testing to ensure the device maintains its integrity over time.

Therefore, I cannot provide the requested information for an AI/ML device based on this submission.
