POSSIS MEDICAL, INC.
The AngioJet Ultra AVX Thrombectomy Set is intended for use with the AngioJet Ultra System in breaking apart and removing thrombus from A-V access conduits ≥ 3 mm in diameter.
AngioJet Ultra AVX Thrombectomy Set is a sterile, single use, disposable set that includes a Thrombectomy Catheter and Pump in one combined unit. The AngioJet Ultra AVX Thrombectomy Set is used with the AngioJet Ultra Console.
The provided text describes a 510(k) submission for the AngioJet® Ultra AVX® Thrombectomy Set, which is a medical device and not an AI/ML software device. Therefore, many of the requested categories related to AI/ML device performance and ground truth establishment are not applicable.
However, I can extract the relevant acceptance criteria and study information available for this medical device from the provided text.

2. Sample size used for the test set and the data provenance
The document states that "Bench and laboratory testing was performed" for biocompatibility and design verification. It does not specify a "test set" in the context of patient data or a specific sample size for a test set. This device is a physical medical device, not an AI/ML algorithm that processes data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. Ground truth as typically defined for AI/ML performance evaluation (e.g., expert labels on medical images) is not relevant for this device's non-clinical testing. The "ground truth" for the device's performance is established by meeting predefined engineering and biocompatibility specifications through bench and lab testing.
4. Adjudication method for the test set
Not applicable. This concept is typically relevant for human review of AI outputs or image interpretation, which is not the nature of this submission.
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 device is a thrombectomy set, a physical medical instrument, not an AI/ML software.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This device is a physical medical instrument, not an AI/ML algorithm.
7. The type of ground truth used
For biocompatibility, the ground truth is established by the specifications defined in the ISO 10993 standards. For design verification, the ground truth is established by engineering specifications for operational pressure, evacuation, infusion rate, dimensions, leak thresholds, etc.
8. The sample size for the training set
Not applicable. This device is a physical medical instrument and does not involve a "training set" in the context of machine learning.
9. How the ground truth for the training set was established
Not applicable, as there is no training set for this device.
