    AI/ML Overview

    The provided document is a 510(k) summary for a medical device (PVS 1700 Steerable Delivery System®-10 Microcatheter), which focuses on demonstrating substantial equivalence to predicate devices rather than providing detailed clinical study results for novel acceptance criteria.

    Therefore, many of the requested details about specific acceptance criteria from a clinical study, sample size, expert ground truth establishment, and MRMC studies are not applicable or available in this type of regulatory submission. The device is primarily evaluated through bench testing and comparison to existing, cleared devices.

    Here's an analysis of the available information:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not explicitly state "acceptance criteria" in a quantitative, pass/fail manner for each test, nor does it provide detailed performance numbers in a table. Instead, it generally states that tests "yielded acceptable results" or "confirmed biocompatibility."

    Acceptance Criteria (Implied)Reported Device Performance
    Biocompatibility: Meet ISO 10993-1 standards for an external communicating, blood contact, short duration (<24 hours) device."Test results confirmed biocompatibility of the subject device when tested as an external communicating, blood contact, short duration (<24 hours) devices."
    Dimensional Inspection: Conform to specified dimensions."Verification testing for the subject device included dimensional inspection… Subject product testing is believed to have yielded acceptable results." (No specific dimensions or ranges reported, but implied conformance to design specifications).
    Hub Integrity: Maintain structural integrity of the hub."Verification testing for the subject device included… hub integrity… Subject product testing is believed to have yielded acceptable results." (No specific integrity metrics reported).
    Flow Rate Measurements: Achieve specified flow rates."Verification testing for the subject device included… flow rate measurements… Subject product testing is believed to have yielded acceptable results." (No specific flow rates reported).
    Burst Strength: Withstand internal pressure without bursting."Verification testing for the subject device included… burst strength… Subject product testing is believed to have yielded acceptable results." (No specific burst pressure reported).
    Tensile Strength: Withstand pulling forces without breaking."Verification testing for the subject device included… tensile strength… Subject product testing is believed to have yielded acceptable results." (No specific tensile strength reported).
    Guidewire Compatibility: Function correctly with guidewires."Verification testing for the subject device included… guidewire compatibility testing and performance under simulated conditions. Subject product testing is believed to have yielded acceptable results." (No specific compatibility metrics reported).
    Torsional Strength: Withstand twisting forces."In addition, torsional strength… tests also yielded acceptable results." (No specific torsional strength reported).
    Torqueability: Ability to transmit torque for steering."In addition, …torqueability… tests also yielded acceptable results." (No specific torqueability metrics reported. The device is described as having "the ability to be steered like a guide wire as needed," which implies this aspect was evaluated and found acceptable).
    Corrosion Resistance: Resist degradation from corrosion."In addition… corrosion resistance tests also yielded acceptable results." (No specific corrosion resistance metrics reported).
    Substantial Equivalence: Similar in design, materials, sterilization, principles of operation, and indications for use to predicate devices, raising no new questions of safety and efficacy."Technological similarities between the PVS 1700 Steerable Delivery System®-10 and predicate devices include the basal tubular design and dimensions, polymeric materials and construction, and hydrophilic coating. In instances where the technological characteristics may differ slightly, it has been demonstrated that there are no new questions raised regarding safety and efficacy of the PVS 1700 Steerable Delivery System®-10." "Based on the indications for use, technological characteristics, and safety and performance testing, the subject PVS 1700 Steerable Delivery System®-10 meets the minimum requirements that are considered adequate for its intended use and is substantially equivalent in design, materials, sterilization, principles of operation and indications for use to current commercially available catheters/cited predicates."

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

    The document does not specify a "test set" in the context of patient data for clinical studies, as the evaluation primarily involved bench testing (performance testing) and biocompatibility testing. Therefore, there is no information on data provenance (country of origin, retrospective/prospective).

    For bench tests, typically multiple units of the device are tested, but the exact sample sizes for each specific test (e.g., how many catheters were burst tested) are not provided in this summary.

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

    Not applicable. The ground truth for this device's evaluation (bench testing) is based on engineering specifications, material science standards (ISO), and direct physical measurements/observations, not on expert consensus from clinical cases.

    4. Adjudication Method for the Test Set

    Not applicable, as this device was evaluated via bench testing rather than through a clinical study requiring human interpretation or adjudication of patient cases.

    5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done

    No. This type of study is not relevant for the regulatory pathway (510(k) for a microcatheter) and the type of evidence presented (bench testing for substantial equivalence).

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

    Not applicable. This device is a physical microcatheter, not an AI algorithm.

    7. The Type of Ground Truth Used

    The ground truth used for proving the device meets acceptance criteria is primarily:

    • Engineering specifications and design requirements: For dimensional inspection, flow rate, tensile strength, burst strength, torqueability, torsional strength, and guidewire compatibility.
    • International Standards (ISO 10993-1 and ISO 10555-1): For biocompatibility and performance testing of intravascular catheters.
    • Comparison to predicate devices: To establish substantial equivalence in terms of technological characteristics and indications for use.

    8. The Sample Size for the Training Set

    Not applicable. This isn't an AI/machine learning device, so there is no concept of a "training set."

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

    Not applicable.

    Study Proving Device Meets Acceptance Criteria:

    The study conducted was a series of "Safety and Performance Tests" on the materials comprising the PVS 1300 Synchro® 0.014" & PVS 1600 Synchro® 0.010" guidewires. These tests were performed in accordance with ISO 11070:1998, Sterile, Single-Use Intravascular Catheter Introducers.

    2. Sample Size for the Test Set and Data Provenance

    The document does not specify the exact sample sizes used for each individual performance test (e.g., how many guidewires were tested for tensile strength or fatigue). It generally states "Subject product testing has yielded acceptable safety & performance outcomes."

    The data provenance is from laboratory testing of the manufactured guidewires by Precision Vascular. It is prospective in the sense that these tests were conducted specifically for this 510(k) submission to demonstrate the device's performance. The country of origin of the data is not explicitly stated, but the manufacturer is based in West Valley City, UT, USA, suggesting the testing was likely conducted in the USA or by a contracted lab.

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

    This question is not applicable. The "ground truth" for a physical medical device like a guidewire is its adherence to predefined engineering specifications and performance standards through physical testing, not expert interpretation of data.

    4. Adjudication Method for the Test Set

    This question is not applicable, as there was no expert review or "ground truth" establishment in the context of interpretation that would require an adjudication method. The results are from objective physical tests.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

    This question is not applicable. This is a physical medical device, not an AI or imaging device that would involve human readers.

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

    This question is not applicable. This is a physical medical device, not an algorithm.

    AI/ML Overview

    The provided document describes the PVS 1600 Synchro® 0.010" Neuro Guidewire and its demonstration of substantial equivalence to predicate devices, rather than a study with specific acceptance criteria and detailed performance metrics as would typically be presented for a new or significantly modified device under a comprehensive clinical trial.

    However, based on the information provided, I can extract the relevant details regarding the safety and performance tests conducted to support its substantial equivalence.

    1. Table of Acceptance Criteria and Reported Device Performance:

    The document does not specify quantitative acceptance criteria with corresponding performance statistics in a tabular format as one would expect from a controlled study with predefined thresholds. Instead, it states that "Subject product testing has yielded acceptable safety & performance outcomes" and that tests "also yielded acceptable results." The criteria are implied to be met if the PVS 1600 Synchro® 0.010" Neuro Guidewire is comparable to its predicate devices and conforms to relevant standards.

    Therefore, the table below provides the performance tests conducted and the general outcome stated in the document. The "Acceptance Criteria" are inferred from the context of demonstrating substantial equivalence to predicate devices and adherence to relevant standards (ISO 10993-1, ISO 11070:1998).

    Acceptance Criteria (Implied)Reported Device Performance
    Biocompatibility in accordance with ISO 10993-1Materials test results confirmed biocompatibility of the subject device when tested as an external communicating, blood contact, short duration (<24 hours) device.
    Conformance to ISO 11070:1998 for Intravascular Catheter Introducers (Verfification Testing)
    - Dimensional InspectionSubject product testing yielded acceptable safety & performance outcomes.
    - Fatigue AssessmentSubject product testing yielded acceptable safety & performance outcomes.
    - Tip FlexibilitySubject product testing yielded acceptable safety & performance outcomes.
    - Tip ShapingSubject product testing yielded acceptable safety & performance outcomes.
    - Tensile StrengthSubject product testing yielded acceptable safety & performance outcomes.
    - Guidewire Compatibility TestingSubject product testing yielded acceptable safety & performance outcomes.
    - Performance under Simulated ConditionsSubject product testing yielded acceptable safety & performance outcomes.
    Torsional Strength (Comparable to Predicates)Yielded acceptable results.
    Torqueability (Comparable to Predicates)Yielded acceptable results.
    Corrosion Resistance (Comparable to Predicates)Yielded acceptable results.
    Technological similarities to predicate devicesTechnological similarities between the PVS 1600 Synchro® 0.010" Neuro Guidewire and the PVS 1300 Synchro™ predicate remain identical. Comparative truth for competitive predicate device features including basal design and dimensions, generic materials & construction, and hydrophilic coating. Where characteristics differ, no new questions raised regarding safety or efficacy.

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

    • Sample Size: The document does not specify numerical sample sizes for the performance tests conducted. It refers to "Performance testing of materials" and "Subject product testing."
    • Data Provenance: The document does not provide details about the country of origin of the data or whether the tests were retrospective or prospective. These appear to be laboratory-based engineering performance tests rather than clinical studies on patient data.

    3. Number of Experts and Qualifications for Ground Truth Establishment (Test Set):

    Not applicable. The document describes engineering and materials performance tests, not clinical studies involving expert interpretation or ground truth establishment based on human review.

    4. Adjudication Method (Test Set):

    Not applicable, as no adjudication by experts for ground truth is mentioned. The tests appear to be objective measurements against engineering standards and comparison to predicate devices.

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

    No, an MRMC comparative effectiveness study was not done. The document describes a 510(k) submission for substantial equivalence based on technological characteristics and performance testing, not a clinical trial evaluating human reader performance with or without AI assistance.

    6. Standalone (Algorithm Only) Performance Study:

    Not applicable. The device is a physical medical instrument (guidewire), not an AI algorithm or software device that would perform a standalone analysis. The performance studies focus on the physical and material properties of the guidewire.

    7. Type of Ground Truth Used:

    For the performance tests, the "ground truth" is implied to be:

    • Compliance with established international standards (ISO 10993-1 for biocompatibility, ISO 11070:1998 for catheter introducers).
    • Comparative performance against existing legally marketed predicate devices, demonstrating similar safety and efficacy profiles.
    • Objective measurements of physical and mechanical properties.

    8. Sample Size for the Training Set:

    Not applicable. The guidewire is a physical device, not an AI, machine learning, or software device that requires a training set.

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

    Not applicable. There is no training set mentioned or implied as this is not an AI/ML device.

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

    • Sample Size: The document does not explicitly state the sample size for each performance test. It refers to "testing" that was performed on the PVS 1400 Guidewire, implying a set of units were tested.
    • Data Provenance: The data appears to be prospective in nature, as it describes tests specifically conducted on the PVS 1400 Guidewire to compare it to predicate devices. The country of origin for the data is not specified, but the submission is to the US FDA.

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

    Not applicable. This device, being a guidewire, relies on objective physical performance tests rather than expert opinion for its "ground truth" or performance evaluation. The "experts" would be the engineers and technicians conducting the physical tests according to established protocols.

    4. Adjudication Method for the Test Set:

    Not applicable. The performance evaluation is based on objective measurements and comparisons to predicate devices, not on expert adjudication of subjective assessments.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:

    No. This type of study (MRMC) is typically used for diagnostic devices (e.g., imaging AI) where human readers interpret cases. The PVS 1400 Guidewire is a physical medical device (guidewire) whose performance is evaluated through bench testing.

    6. If a Standalone Study (algorithm only without human-in-the-loop performance) was done:

    Yes, in essence. The performance data presented (tip flexibility, tensile strength, torqueability, etc.) are all standalone evaluations of the PVS 1400 Guidewire's physical characteristics, often compared to predicate devices. There is no "algorithm" in the sense of a software-based AI, but the device's inherent performance is tested independently of human intervention during its function in the context of these tests.

    7. The Type of Ground Truth Used:

    The ground truth used for performance validation is primarily objective physical measurements and comparisons to established predicate devices. For biocompatibility, the ground truth is established by standardized biological tests and their respective pass/fail criteria. For sterilization, the ground truth is the measured residual levels of sterilants compared to specified limits.

    8. The Sample Size for the Training Set:

    Not applicable. As a physical medical device, there is no "training set" in the context of machine learning or AI. Its design and manufacturing process are refined based on engineering principles and material science, not data training.

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

    Not applicable for the reasons stated above (no training set for a physical device). The "ground truth" for the device's fundamental design aspects would come from engineering specifications, material properties, and clinical requirements for guidewires.
