    Device Description

    The Axium™ Detachable Coil and Axium™ Prime Detachable Coil consist of a platinum embolization coil attached to a composite implant delivery pusher with a radiopaque positioning marker and a hand-held Instant Detacher (I.D.) which when activated detaches the coil from the delivery pusher tip. The I.D. is sold separately.

    AI/ML Overview

    The document provided focuses on the substantial equivalence of the "Axium™ Detachable Coil" and "Axium™ Prime Detachable Coil" with the addition of fluorosafe markers. The primary purpose of the submission is to demonstrate that these changes do not raise new questions of safety and effectiveness compared to the predicate devices. Therefore, the "device" in question is not an AI/ML powered diagnostic device, but rather a neurovascular embolization device with a minor design change.

    2. Sample Size for the Test Set and Data Provenance

    The document does not explicitly state the sample sizes used for each specific test in the "Test Set." However, it repeatedly mentions "All units" or "All units met" indicating that a sufficient number of samples were tested to achieve statistical significance or to demonstrate compliance.

    The data provenance is not specified in terms of country of origin. The studies are described as "Design verification and validation" (in-house testing) and based on applicable ISO/ASTM/USP standards, suggesting a laboratory-based, prospective testing approach. No mention of retrospective or prospective clinical data for the test set is present, as this is a pre-market submission focused on device performance rather than clinical outcomes.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications

    For the "In vitro Simulated Use Study," it states that "A simulated interventional procedure was performed by physicians." The exact number of physicians or their specific qualifications (e.g., "radiologist with 10 years of experience") are not provided.

    For the "Radiopacity" test (from the predicate device), "Physicians were shown fluoroscopic images." Again, the specific number and qualifications of these physicians are not detailed.

    4. Adjudication Method for the Test Set

    The document does not describe any formal adjudication method (e.g., 2+1, 3+1) for the tests. The results indicate a direct pass/fail or "met acceptance criteria" outcome, implying consensus on the directly measurable or observable results rather than a subjective assessment requiring adjudication. For physician-evaluated tests, the document indicates a general 'acceptance criteria met' without detailing disagreement resolution.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    No MRMC comparative effectiveness study was mentioned. The studies focused on device performance characteristics rather than comparing human reader performance with or without AI assistance. The device itself is a physical catheter, not an AI-powered diagnostic tool.

    6. Standalone (i.e., algorithm only without human-in-the-loop performance) Study

    No standalone algorithm performance study was done. This is consistent with the nature of the device as a physical medical instrument, not a software algorithm.

    7. Type of Ground Truth Used

    The ground truth for most performance tests was established by adherence to recognized international standards (ISO, ASTM, USP) and predefined internal specifications for various physical, chemical, and biological properties. This includes:

    • Physical Measurements: Dimensional accuracy (ID, OD, length), tensile strength metrics, burst pressure values, torque limits, kink resistance thresholds.
    • Chemical/Biological Properties: Biocompatibility assays (cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemocompatibility), chemical compatibility.
    • Functional Performance: Leak testing, coating integrity, particulate count, simulated use performance, radiopacity (as confirmed by physicians).
    • Sterility and Packaging Integrity: Demonstrated through sterilization validation and packaging tests.

    8. Sample Size for the Training Set

    No training set is applicable or mentioned. This device is a physical medical device, not a machine learning model that requires a training set.

    9. How the Ground Truth for the Training Set Was Established

    Not applicable as there is no training set for a physical device.

    AI/ML Overview

    This document does not describe an AI/ML device and therefore does not contain the information requested in your prompt regarding acceptance criteria and studies for AI/ML device performance.

    The document is a 510(k) premarket notification summary for the Axium™ Detachable Coil and Axium™ Prime Detachable Coil, which are neurovascular embolization devices. It describes a proposed change to the labeling concerning the accessory sheath (from femoral to arterial, allowing radial access) and the removal of certain peripheral vasculature indications for specific models.

    The performance data presented are for bench testing of the physical device (e.g., ease of delivery, detachment reliability, retractability, retrieval) and explicitly states:

    • "The determination of substantial equivalence is based upon non-clinical bench testing as there is no change to the intended use, fundamental scientific technology, or materials of construction." (Regarding animal and clinical data).

    AI/ML Overview

    The Solitaire X Revascularization Device is designed to restore blood flow by removing thrombus in patients experiencing ischemic stroke. The device, specifically the 3mm variant, underwent several tests to demonstrate its performance and safety, leading to its substantial equivalence determination.

    Here's a breakdown of the acceptance criteria and supporting studies:

    1. Table of Acceptance Criteria and Reported Device Performance:

    TestAcceptance CriteriaReported Device Performance
    Delivery ForceVerified maximum delivery force through microcatheters to the M2 section of a representative tortuous anatomical model.Acceptance criteria met
    Resheathing TestVerified that the device is able to be resheathed into microcatheters in the M2 section of a representative tortuous anatomical model.Acceptance criteria met
    System LengthsDevice system length measured from the proximal end of the pushwire to the proximal end of the keyhole marker band and total system length in sheath.Acceptance criteria met
    Durability and Reusability TestVerified that the device is able to be reliably deployed and resheathed into a microcatheter for four times for four passes in a clinically relevant tortuosity model.Acceptance criteria met
    System Tensile Strength TestPerformed following simulated use via delivery through a microcatheter in a clinically relevant tortuosity model.Acceptance criteria met
    Distal and Body Marker Tensile TestPerformed following simulated use via delivery through a microcatheter in a clinically relevant tortuosity model.Acceptance criteria met
    Torque TestVerified if the stent joint can withstand a minimum of one rotation in a clinically relevant tortuosity model.Acceptance criteria met
    Radial Outward Force (ROF)Measured to specification.Acceptance criteria met
    Stent Outer DiameterAverage device diameter measured post-simulated use testing.Acceptance criteria met
    Particulate TestParticulates generated during simulated use (including multiple deployment cycling).Acceptance criteria met
    Fluorosafe Marker DistanceDistance from the distal tip of the device subassembly to the distal end of the fluorosafe marker in-sheath is measured.Acceptance criteria met
    BiocompatibilityA risk-based approach assessing the materials and manufacturing of the introducer sheath indicated no change in biocompatibility profile.Minor material differences in introducer sheath concluded not to change biocompatibility profile.
    Animal Study Safety and UsabilityDemonstrated safety and usability in a porcine model at sub-acute and 30-day (chronic) time points.Safety and usability results suggest substantial equivalence to the predicate device.
    Clinical Study (Retrospective Analysis)Evaluation of vessel sizes using existing registry data to support substantial equivalence.Retrospective analysis of STRATIS registry data performed.

    2. Sample Size Used for the Test Set and Data Provenance:

    The document mentions a retrospective analysis of vessel sizes using the STRATIS registry data as a "clinical" study to support substantial equivalence. While it explicitly states this, it does not provide the sample size of this retrospective analysis.

    • Data Provenance: The STRATIS registry data was "previously submitted in K193576," suggesting it's existing, likely multi-center, clinical trial or registry data. The country of origin is not specified but is likely international, given the nature of major stroke registries. It is retrospective.

    3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts:

    The document does not provide information on the number of experts used or their qualifications for establishing ground truth for the retrospective analysis of vessel sizes. Given it's a "retrospective analysis of vessel sizes," the ground truth would likely be based on imaging reports and clinical assessments already documented in the STRATIS registry by the original clinicians and radiologists involved in the patient care and data collection.

    4. Adjudication Method for the Test Set:

    The document does not specify an adjudication method for the retrospective analysis. As it relies on existing registry data, the "ground truth" would implicitly be the clinical diagnoses and measurements recorded at the time of the original study or patient care within the STRATIS registry.

    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:

    The document does not describe an MRMC comparative effectiveness study involving human readers with or without AI assistance. The described "clinical" study is a retrospective analysis of vessel sizes, not an evaluation of AI assistance for human readers.

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

    The document does not describe a standalone performance study of an algorithm. The Solitaire™ X Revascularization Device is a physical mechanical thrombectomy device, not an AI or software algorithm. The "clinical" study mentioned is a retrospective analysis of vessel sizes, likely performed to understand the distribution of vessel sizes relevant to the device's application, rather than to evaluate an algorithm's performance.

    7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.):

    For the retrospective analysis, the ground truth would inherently be

    • Imaging measurements and clinical diagnoses documented within the STRATIS registry data. This would include measurements of vessel sizes and characterization of occlusions based on imaging (e.g., CTA, MRA) and patient outcomes. It's a form of outcomes data and expert-reported imaging findings from the original clinical context.

    8. The Sample Size for the Training Set:

    The document does not mention a training set for an algorithm. The Solitaire™ X Revascularization Device is a physical medical device, not a machine learning model that requires training data.

    9. How the Ground Truth for the Training Set Was Established:

    As there is no mention of a training set for an algorithm, this question is not applicable.

    AI/ML Overview

    The provided text describes the regulatory clearance for the "Phenom Catheters" and includes performance data from bench testing. However, it does not describe any study involving AI, human readers, or the establishment of ground truth for such a study. Therefore, I cannot fulfill your request for information related to AI or human-in-the-loop performance.

    The document focuses on demonstrating substantial equivalence to predicate devices through non-clinical bench testing. There is no mention of acceptance criteria or performance metrics in the context of an AI-based device, a multi-reader multi-case (MRMC) study, or standalone algorithm performance.

    Here's a breakdown of the information that is present in the document, framed against your request:

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

    The document provides a table of "Tests" with "Test Method Summary" and "Results." The "Results" column implicitly indicates that the acceptance criteria were met for each test, as it states "The Phenom™ Catheters met the acceptance criteria for..." or "acceptable friction force," "compatible for use," etc.

    • 6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This device is not an algorithm.
    • 7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable. The "ground truth" for the catheter is its ability to perform according to engineering specifications and biocompatibility standards.
    • 8. The sample size for the training set: Not applicable. This is not an AI model requiring a training set.
    • 9. How the ground truth for the training set was established: Not applicable.

    In summary, the provided document details the regulatory clearance of a physical medical device (catheter) based on non-clinical performance and biocompatibility testing, not an AI software/device.

    Intended Use

    The Rebar™ Micro Catheter is intended for the delivery of interventional devices or contrast media into the vasculature of the peripheral and neuro anatomy.

    Device Description

    The Rebar" Micro Catheter is an endhole, single-lumen catheter designed to be introduced over a steerable guidewire into the vasculature. The proximal end of the catheter incorporates a standard luer adapter to facilitate the attachment of accessories. The catheter has a semi-rigid proximal shaft which transitions into the flexible distal shaft to facilitate the advancement of the catheter in the anatomy. Single or dual radiopaque markers at the distal end facilitate fluoroscopic visualization. The outer surface of the catheter is coated to increase lubricity.

    AI/ML Overview

    The provided text does not describe a study involving a device that uses AI or machine learning. Instead, it describes a 510(k) premarket notification for a medical device called the "Rebar™ Micro Catheter." This submission is focused on demonstrating substantial equivalence to an existing predicate device based on material changes (e.g., to the hub material and adhesive) and associated non-clinical bench testing.

    Therefore, I cannot provide the information requested in your prompt regarding acceptance criteria and a study proving an AI/ML device meets them, as the provided document pertains to a traditional, non-AI medical device clearance.

    The document discusses:

    • Device: Rebar™ Micro Catheter (a vascular microcatheter)
    • Purpose: Delivery of interventional devices or contrast media into the vasculature.
    • Regulatory Pathway: 510(k) premarket notification, aiming for substantial equivalence to a previously cleared Rebar™ Micro Catheter (K093750).
    • Changes: Primarily changes to the material of the catheter hub (from Polypropylene to Trogamid) and the adhesive used.
    • Proof of Equivalence: Non-clinical bench testing and biocompatibility data, rather than clinical trials or AI/ML performance studies.

    The acceptance criteria listed are for physical and functional properties of the catheter (e.g., hub integrity, pressurization, tensile strength) and not related to AI/ML performance metrics like accuracy, sensitivity, or specificity. There is no mention of a test set, ground truth acquisition involving experts, MRMC studies, or training sets, as these concepts are not applicable to the type of device and study described.
