The provided text describes a 510(k) premarket notification for the ClotTriever Thrombectomy System, focusing on a labeling change rather than a study proving new performance claims or AI model acceptance criteria. The document states that the change is to replace "fibrous" and "adherent" with "predominantly fibrous" and "firmly adherent" from the contraindications. It explicitly mentions that Non-Clinical Testing was not required to support the change and that Clinical Testing was originally submitted in a previous 510(k) (K193462, cleared on September 9, 2020). Therefore, the document does NOT contain the information needed to answer the prompt regarding acceptance criteria and performance studies for a device, especially not those related to an AI model.
The prompt specifically asks for details about AI model acceptance criteria and performance studies (e.g., sample size, expert ground truth, MRMC studies, standalone performance), which are not discussed in this FDA 510(k) clearance letter for a thrombectomy system.
Therefore, I must state that the requested information is not available in the provided text.

Mini-ClotTriever Thrombectomy System
The Mini-ClotTriever Thrombectomy System is indicated for:
· The non-surgical removal of emboli and thrombi from blood vessels.
· Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel.
The Mini-ClotTriever Thrombectomy System is intended for use in the peripheral vasculature.
The Mini-ClotTriever Thrombectomy System is not intended for use in deep vein thrombosis (DVT) treatment.
The Mini-ClotTriever (“MCT”) Thrombectomy System is a single-use, over-the-wire, catheter-based system for the minimally invasive treatment of thromboemboli in the peripheral vasculature. The system is comprised of two main components packaged separately:
Mini-ClotTriever Sheath (8 Fr)
Mini-ClotTriever Catheter (8 Fr)
The MCT Sheath is placed in the target vessel, and, after its funnel is expanded, the MCT Catheter is inserted through the sheath and advanced past the thrombus. The MCT Catheter coring element is deployed to engage the clot and retracted into the MCT Sheath to capture the targeted thrombus. Additional clot may be removed by aspiration through the sheath with a syringe (not provided). After the procedure is complete, the MCT Catheter and MCT Sheath are removed from the patient.
The provided text describes the 510(k) premarket notification for the Mini-ClotTriever Thrombectomy System. This submission focuses on demonstrating substantial equivalence to a predicate device (Inari ClotTriever Thrombectomy System, K210689) through non-clinical testing. It does not present a study proving the device meets acceptance criteria related to AI/algorithm performance.
The document primarily covers:
- Device Description: A mechanical thrombectomy system for non-surgical removal of emboli and thrombi from blood vessels in the peripheral vasculature.
- Comparison to Predicate: Details on the similarities and differences in design, materials, and operational principles between the Mini-ClotTriever and its predicate device.
- Non-Clinical Testing: A list of bench tests performed (e.g., biocompatibility, sterilization, dimensional inspections, simulated use, tensile testing, corrosion testing) to demonstrate that the device conforms to established product specifications and the modifications do not raise new questions of safety or effectiveness.
- Conclusion: The device is substantially equivalent to the predicate device based on non-clinical testing, and neither animal nor clinical testing was required for this determination.
Based on the provided text, none of the specific information requested about AI/algorithm acceptance criteria and performance (e.g., sample size for test sets, expert consensus, MRMC studies, standalone performance, training set details) can be extracted because the device is a medical instrument, not an AI/algorithm-based diagnostic or therapeutic tool for which such criteria would apply.
Therefore, I cannot populate the table or answer the specific questions related to AI/algorithm performance. The document describes a mechanical device and its testing, not an AI study.

This document is a 510(k) summary for the Inari Medical ClotTriever Thrombectomy System. It outlines the FDA's determination of substantial equivalence for a modified version of the device.
Based on the provided text, the device in question is not an AI/ML powered device. It's a physical medical device designed for the non-surgical removal of thrombi and emboli. Therefore, the questions related to AI/ML device performance, such as acceptance criteria based on AI metrics, sample sizes for test/training sets for AI, expert adjudication, MRMC studies, and standalone algorithm performance, are not applicable to this document.
The document states:
- "Non-Clinical Testing: Non-clinical testing was not required to support the change to the Indications for Use."
- "Clinical Testing: The CLOUT registry clinical data supporting this labeling change was previously submitted in the ClotTriever Thrombectomy System 510(k) (K193462, cleared on September 9, 2020). No additional clinical data was deemed necessary to determine substantial equivalence of the subject and predicate devices."
This means that the current 510(k) submission (K210190) is for a labeling change (specifically, removing "chronic clot" from a contraindication) for an already cleared device, and no new performance testing (clinical or non-clinical) was conducted or required for this specific submission. The substantial equivalence determination is based on the previously submitted data for K193462.
Therefore, I cannot provide the requested information about acceptance criteria and study details for an AI/ML device from this document. The document describes a traditional medical device and a submission for a minor labeling modification.

2. Sample Size Used for the Test Set and Data Provenance
The provided information focuses on non-clinical testing (e.g., bench testing, mechanical tests). There is no information provided regarding a "test set" in the context of patient data.
- Sample Size: Not applicable for a clinical test set as no clinical testing was performed for this submission. For the non-clinical tests, specific sample sizes are not explicitly stated for each test, but it is implied that sufficient samples were used to meet the verification and validation requirements.
- Data Provenance: Not applicable for a clinical test set. For the non-clinical tests, the data provenance is from the manufacturer's (Inari Medical) internal testing.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not applicable as the submission states: "Clinical testing was not required for the determination of substantial equivalence." Therefore, no clinical ground truth was established by experts for a test set in this context.
4. Adjudication Method for the Test Set
This information is not applicable as no clinical test set requiring expert adjudication was utilized.
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
An MRMC comparative effectiveness study was not done. The submission explicitly states: "Clinical testing was not required for the determination of substantial equivalence." This implies no human-in-the-loop performance evaluation or comparison with AI assistance.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
This information is not applicable. The ClotTriever Thrombectomy System is a physical medical device (catheter system), not an AI algorithm. Therefore, "standalone algorithm performance" is not relevant to this submission.
7. The Type of Ground Truth Used
For the non-clinical testing conducted, the "ground truth" used was established product specifications, engineering standards, and the performance of the predicate device (K173470). In other words, the device's performance was compared against predetermined acceptance criteria derived from its design requirements and the known characteristics of equivalent devices.
8. The Sample Size for the Training Set
This information is not applicable. As a physical medical device, there is no "training set" in the context of machine learning or AI.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable for the same reason as point 8.

ClotTriever Thrombectomy System, ClotTriever Catheter, ClotTriever Sheath
The ClotTriever Thrombectomy System consists of the ClotTriever Catheter and ClotTriever Thrombectomy System is indicated for:
- · The non-surgical removal of soft thrombi and emboli from blood vessels.
- · Injection, infusion, and/or aspiration of contrast media and other fluids into or from a blood vessel.
The ClotTriever Thrombectomy System is intended for use in the peripheral vasculature.
The ClotTriever Thrombectomy System is a single-use, sterile medical device system designed for use in the peripheral vasculature. The ClotTriever Thrombectomy System consists of the ClotTriever Sheath and the ClotTriever Catheter. The ClotTriever Sheath consists of a polymeric sheath equipped with a self-expanding distal mesh funnel, a flush/aspiration port with tubing clamp, and a proximal hemostatic valve. A dilator is provided to aid insertion. Other provided accessories include a clot reservoir, a flush port adapter, an aspiration insert, funnel loading tool, and a 60 cc syringe. The ClotTriever Catheter consists of four pre- assembled polymeric coaxial catheters terminating in an expandable coring element and thrombus collection bag. At the proximal end of the catheter is a handle used to enable tensioning of the coring element. Two ports terminating in stopcocks are provided for de-airing the catheter shafts. To aid in fluoroscopic visualization, the dilator and ClotTriever Catheter distal tips are radiopaque, and radiopaque marker bands are located on the coring element shaft at the proximal end of the expandable coring element, and at the distal ends of the ClotTriever Sheath and ClotTriever Catheter outer shaft.
The prompt asks to describe the acceptance criteria and the study that proves the device meets the acceptance criteria, based on the provided text. However, the provided text does not contain details about specific acceptance criteria (e.g., numerical thresholds for performance metrics) or a study with detailed results that explicitly "prove" the device meets these criteria. Instead, it describes non-clinical testing performed to establish substantial equivalence to a predicate device.
Therefore, many of the requested details cannot be extracted directly from the provided document. I will answer based on what is available, and explicitly state when information is missing.
Here's the breakdown of what can be inferred/extracted:
