    Medline ReNewal Reprocessed Boston Scientific Dynamic XT Unidirectional Steerable Diagnostic Catheter

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    Medline ReNewal Reprocessed Boston Scientific Dynamic XT Unidirectional Steerable Diagnostic Catheters are indicated for use to diagnose cardiac arrhythmia.

    Device Description

    The Medline ReNewal Reprocessed Boston Scientific Dynamic XT Unidirectional Steerable Diagnostic Catheters are intended for temporary intracardiac sensing, recording, stimulation, and temporary pacing during the evaluation or cardiac arrhythmias. The steerable diagnostic electrode catheters are radiopaque, flexible, insulated catheters with a polymer shaft, each having a mechanical operating mechanism. In each catheter the polymer shaft connects to the catheter handle whereby the curve or loop is actuated by a single pull cable. The Dynamic XT Catheters have a plunger mechanism, which, when moved forward or back, results in curvature of the distal tip.

    AI/ML Overview

    The provided FDA 510(k) clearance letter (K250772) pertains to a reprocessed medical device, specifically the Medline ReNewal Reprocessed Boston Scientific Dynamic XT Unidirectional Steerable Diagnostic Catheter. This document largely focuses on demonstrating substantial equivalence to a predicate device through comparison of technological characteristics and functional performance testing.

    Crucially, the provided text does not contain information about acceptance criteria or a "study that proves the device meets the acceptance criteria" in the context of an AI/ML powered device, as assumed by the structured request. The clearance is for a physical medical device (a reprocessed catheter), not a software or AI/ML algorithm. Therefore, many of the requested categories (e.g., sample size for test/training sets, expert ground truth, MRMC studies, standalone algorithm performance) are not applicable to the information contained within this document.

    The "Non-clinical Testing Summary" section describes the types of tests performed to demonstrate safety and effectiveness for a reprocessed physical device. These tests assess the physical and electrical properties of the catheter after reprocessing.

    I will attempt to answer the applicable sections based on the information provided, and explicitly state when information is not available or not applicable due to the nature of the device.


    Description of Acceptance Criteria and Study to Prove the Device Meets Acceptance Criteria for K250772

    As noted above, this 510(k) clearance is for a reprocessed physical medical device (a catheter), not an AI/ML-powered device. Therefore, the "acceptance criteria" and "study" described herein are related to the physical, functional, and safety performance of the reprocessed catheter compared to the original, new device, rather than a statistical evaluation of an AI algorithm's diagnostic performance.

    1. Table of Acceptance Criteria and Reported Device Performance

    The FDA 510(k) summary (pages 6-8) describes the non-clinical testing performed to establish substantial equivalence. While explicit numerical acceptance criteria values are not provided in this public summary, the types of tests indicate the areas where the reprocessed device must perform equivalently to the predicate. The "reported device performance" is implied by the statement "found to be substantially equivalent to the predicate device based on the following tests."

    Acceptance Criteria Category (Implied)Reported Device Performance (Implied)
    Functional Performance (overall)Found to be substantially equivalent to the predicate device.
    Visual InspectionMet acceptance criteria (implied by "found to be substantially equivalent").
    Dimensional MeasurementMet acceptance criteria (implied by "found to be substantially equivalent").
    Electrical SafetyMet acceptance criteria (implied by "found to be substantially equivalent").
    Mechanical CharacteristicsMet acceptance criteria (implied by "found to be substantially equivalent").
    ContinuityMet acceptance criteria (implied by "found to be substantially equivalent").
    IsolationMet acceptance criteria (implied by "found to be substantially equivalent").
    ResistanceMet acceptance criteria (implied by "found to be substantially equivalent").
    Corrosion ResistanceMet acceptance criteria (implied by "found to be substantially equivalent").
    Cleaning ValidationValidated (implies meeting pre-defined criteria for residual contaminants).
    BiocompatibilityMet acceptance criteria (implies no adverse biological reactions).
    Packaging and Shelf Life ValidationValidated (implies maintaining sterility and integrity over time).
    Sterilization ValidationValidated (implies achieving required Sterility Assurance Level).
    Product StabilityMet acceptance criteria (implies maintaining performance over time).
    Reprocessing Cycle LimitDoes not exceed validated reprocessing cycles (stated as 1).

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

    • Sample Size: The document does not specify the exact number of reprocessed catheters (the "test set") used for each functional and safety test. For medical devices, particularly reprocessed ones, sample sizes are typically determined by statistical rationale to demonstrate equivalence or meet performance specifications, but these details are not in the summary.
    • Data Provenance: This relates to the testing of the reprocessed device itself. The data would be prospective, as it involves testing reprocessed devices manufactured by Medline ReNewal. The country of origin for the data would be where Medline ReNewal conducts its testing, likely the USA given the FDA clearance.

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

    • N/A. This concept applies to diagnostic or AI/ML devices where a "ground truth" is established by human experts (e.g., radiologists interpreting images). For a reprocessed physical device, "ground truth" is established by objective engineering and safety standards (e.g., measuring dimensions against specifications, testing electrical resistance against a standard). The "experts" would be qualified engineers and technicians performing the tests.

    4. Adjudication Method for the Test Set

    • N/A. Adjudication (e.g., 2+1, 3+1 consensus) is used in studies with human readers interpreting data, often to resolve discrepancies in diagnoses or interpretations. This is not applicable to the direct physical and functional testing of a medical device like a catheter.

    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

    • N/A. This type of study is relevant for AI/ML-assisted diagnostic tools, not for a reprocessed physical device like this catheter. The clearance is based on the catheter's physical and functional equivalence to new catheters, not on improving human diagnostic accuracy.

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

    • N/A. This refers to the performance of an AI/ML algorithm on its own. It is not applicable to a physical medical device.

    7. The Type of Ground Truth Used

    • For the physical and functional aspects of the reprocessed catheter, the "ground truth" is established by:
      • Engineering Specifications: The design and performance specifications of the original (predicate) new device. The reprocessed device must meet these same specifications.
      • Regulatory Standards: Relevant FDA and international standards for medical device safety and performance (e.g., electrical safety, biocompatibility, sterilization).
      • Objective Measurements: Direct measurements (e.g., dimensions, electrical properties, mechanical strength) and analytical tests (e.g., for residual contaminants).

    8. The Sample Size for the Training Set

    • N/A. "Training set" refers to data used to train an AI/ML algorithm. This is not applicable to a physical reprocessed medical device. The "training" for this device is the validation of the reprocessing procedure itself.

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

    • N/A. Since there is no "training set" in the AI/ML sense, this question is not applicable. For a reprocessed device, the "ground truth" is inherent in the established manufacturing and safety standards that the reprocessing procedure must meet. The reprocessor (Medline ReNewal) developed and validated a controlled process (cleaning, inspection, testing, packaging, sterilization) to ensure that the reprocessed catheter performs equivalently to a new device.

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The Medline ReNewal Reprocessed Biosense Webster SOUNDSTAR eco Diagnostic Ultrasound Catheters 8F, 8FG, 10F 10FG are indicated for intra-cardiac and intra-luminal visualization of cardiac and great vessel anatomy and physiology as well as visualization of other devices in the heart. When used with compatible CARTO 3 EP Navigation Systems, the SOUNDSTAR eco Catheter provides location information.

    Device Description

    The Medline ReNewal Reprocessed Biosense Webster SOUNDSTAR eco Diagnostic Ultrasound Catheters 8F, 8FG, 10F, 10FG are licensed for single use only. Models differ in shaft diameter (8F or 10F) and ultrasound system compatibility (Siemens [8F and 10F] or GE [8FG and 10FG]). The catheter consists of a CARTO connector, SwiftLink (ultrasound) connector, handle and shaft. In the distal tip of each catheter's shaft are a 64-element ultrasound transducer providing 2D imaging and a 3D location sensor providing location information to the compatible CARTO 3 Electrophysiology (EP) Navigation System. The deflection and tension knobs on the handle are used to articulate the distal tip and control the image plane orientation with four-directional (anterior-posterior, left-right) deflection.

    AI/ML Overview

    The provided FDA 510(k) clearance letter pertains to the Medline ReNewal Reprocessed Biosense Webster SOUNDSTAR eco Diagnostic Ultrasound Catheters. This document outlines the regulatory review and approval process for a reprocessed medical device, asserting its substantial equivalence to original predicate devices.

    However, the provided text does not contain any information regarding specific acceptance criteria for AI/ML performance, nor does it describe a study involving AI assistance or standalone AI performance evaluation. The "Non-clinical Testing Summary" focuses on the physical, electrical, and reprocessing aspects of the reprocessed catheter itself (e.g., functional performance, electrical safety, cleaning validation, biocompatibility, sterilization validation, packaging and shelf life). It explicitly states: "The current submission does not include consoles or any other system components as part of this respective submissions." The device subject to clearance is an ultrasound catheter, not an AI-powered diagnostic system.

    Therefore, I cannot fulfill the request to describe the acceptance criteria and the study that proves the device meets the acceptance criteria for AI/ML device performance based on the provided document. The document pertains to a physical medical device (an ultrasound catheter) and its reprocessing, not an AI/ML-driven diagnostic or assistive technology.

    If you have a document describing an AI/ML device and its performance study, I would be happy to analyze it according to your requested criteria.

    The package includes the main unit, a charging cable, a user manual, a tray. Each model is equipped with a single button to turn the device on or off. The device will automatically shut down after 5 minutes of operation.

    AI/ML Overview

    The provided FDA 510(k) clearance letter and summary for the Radiant Renewal Skincare Wand does not contain information about clinical performance, acceptance criteria for clinical efficacy, or a study proving that the device meets such criteria.

    The document explicitly states:

    "Clinical testing was not needed for this 510(k). The non-clinical performance testing described above is sufficient to support that the device can be used safely and effectively."

    Therefore, I cannot provide the requested information regarding acceptance criteria and the study that proves the device meets those criteria from the input given. The clearance was based on non-clinical tests demonstrating safety and substantial equivalence to predicate devices, not on a clinical study evaluating the device's performance for its intended use (wrinkle reduction and acne treatment) against specific efficacy acceptance criteria.

    However, I can still extract details about the non-clinical tests performed:

    1. A table of acceptance criteria and the reported device performance (for non-clinical tests):

    While explicit "acceptance criteria" and "reported performance" in a quantitative sense for efficacy are not present, the non-clinical tests performed aimed to demonstrate compliance with various safety and performance standards. The "performance" in this context is the statement of "compliance."

With the catheter, the physician can maneuver the imaging plane located inside the catheter tip to see the region of interest. The physician can steer the catheter to optimize tissue visualization. The catheters are to be used only on systems with which they have been tested and found compatible.

    AI/ML Overview

    This document is a 510(k) premarket notification for a reprocessed medical device, specifically an ultrasound catheter, not a new device involving AI or complex software. As such, the information requested in your prompt regarding acceptance criteria and studies that prove a device meets acceptance criteria specifically for AI/Software performance is not present in this document.

    The 510(k) submission for the Medline ReNewal Reprocessed Siemens ACUSON AcuNav Ultrasound Catheter 10F focuses on demonstrating substantial equivalence to a predicate device (the original, single-use Siemens AcuNav Diagnostic Ultrasound Catheter). This is achieved through non-clinical testing to show that the reprocessed device performs as safely and effectively as the original.

    Therefore, many of the specific points you've asked for, such as sample size for a test set for AI performance, number of experts for ground truth, adjudication methods, MRMC studies, standalone AI performance, and ground truth for training data, are not applicable to this type of device and submission.

    However, I can extract information related to the non-clinical testing performed to establish substantial equivalence for this reprocessed device, which serves as its "proof" of meeting performance criteria.

    Here's an interpretation based on the provided document:

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

    The document doesn't present a formal table of quantitative acceptance criteria with numerical performance data. Instead, it lists the types of non-clinical tests performed to demonstrate that the reprocessed device's functional characteristics are substantially equivalent to the predicate device. The implied acceptance criterion for each test is that the reprocessed device performs comparably to the original to ensure safety and effectiveness.

    Test CategoryImplied Acceptance CriterionReported Device Performance
    Functional PerformanceEquivalent to predicate; safe and effective in intended use."evaluated and found to be substantially equivalent"
    Simulated UseFunction similar to original in a simulated environment.Performed, result is substantial equivalence.
    Artificial SoilingCleaning processes effective after simulated contamination.Performed, result is substantial equivalence.
    Visual InspectionNo detrimental changes or defects after reprocessing.Performed, result is substantial equivalence.
    Mechanical CharacteristicsMaintains physical integrity and functionality.Performed, result is substantial equivalence.
    Ultrasound Transducer TestingAcoustic performance equivalent to original.Performed, result is substantial equivalence.
    Dimensional AnalysisDimensions remain within specified tolerances.Performed, result is substantial equivalence.
    Device FunctionalityPerforms all intended functions.Performed, result is substantial equivalence.
    Electrical SafetyMeets dielectric and current leakage standards.Performed; "dielectric and current leakage"
    Cleaning ValidationEffective removal of contaminants.Performed
    BiocompatibilityNo adverse biological reactions.Performed
    Sterilization ValidationAchieves required sterility assurance level (SAL).Performed ("bioburden testing; ethylene oxide and ethylene chlorohydrin residuals testing; and bacteriostasis/fungistasis")
    Packaging and Shelf Life ValidationMaintains integrity and sterility over shelf life.Performed
    Product StabilityRemains stable over time.Performed

    2. Sample sized used for the test set and the data provenance:

    • Sample Size for Test Set: The document does not specify the exact number of units/samples used for each type of non-clinical test. This level of detail is typically found in the full testing reports submitted to the FDA, not in the public 510(k) summary.
    • Data Provenance: The tests were conducted by Medline ReNewal. While not explicitly stated, such tests are generally conducted at their facilities or certified labs. The country of origin of the data would be the USA (Oregon, specifically, as per the address). The data is prospective in the sense that Medline ReNewal specifically conducted these tests to support this 510(k) submission for their reprocessed device.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • Not applicable. This relates to AI/software performance evaluation where human experts establish ground truth for image interpretation or diagnosis. For a reprocessed physical device, "ground truth" is established by adherence to engineering specifications, performance standards, and established test methodologies (e.g., AAMI standards for sterilization, ISO standards for biocompatibility). The "experts" involved would be engineers, microbiologists, and other technical personnel who design and execute these tests, and interpret the results against pre-defined success criteria.

    4. Adjudication method for the test set:

    • Not applicable. This refers to consensus-building among medical experts for labeling data, which is not relevant for the physical performance testing of a reprocessed medical device. Test results are compared against objective criteria and engineering specifications.

    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 type of study is relevant for AI-powered diagnostic devices. This submission is for a reprocessed ultrasound catheter.

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

    • Not applicable. This refers to the performance of a software algorithm.

    7. The type of ground truth used:

    • For this reprocessed device, "ground truth" is based on engineering specifications, established performance standards (e.g., mechanical strength, electrical safety, acoustic performance), and validated manufacturing processes (e.g., cleaning efficacy, sterilization efficacy). The original predicate device's performance also serves as a benchmark for comparison.

    8. The sample size for the training set:

    • Not applicable. There is no "training set" as this is not an AI/machine learning device.

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

    • Not applicable. There is no "training set."

    The package includes the main unit, a charging cable, a user manual, a tray and a cosmetic container(only for model HD-70). An optional squeeze tube is also available but not included by default. Except for model HD-70, which features an additional rotating rock button, other models are equipped with a single button to turn the device on or off and switch treatment modes. The device can also be used with other skincare products such as face creams, eye creams, serums, etc.
    The device will automatically shut down after the recommended duration of 2 minutes. If you wish to continue the treatment, simply press the button to turn the device back on.

    AI/ML Overview

    The provided document is a 510(k) premarket notification for cosmetic devices (LED light therapy for wrinkle reduction and acne treatment), not a medical device requiring clinical studies with AI, human readers, or complex ground truth establishment. Therefore, most of the requested information regarding AI performance, expert consensus, and multi-reader studies is not applicable.

    The document primarily focuses on demonstrating substantial equivalence to predicate devices through non-clinical performance testing.

    Here's an assessment based on the provided text:

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

    The document doesn't explicitly state "acceptance criteria" in the format of a table with numerical thresholds for performance. Instead, it outlines the non-clinical tests performed to ensure safety and effectiveness, assuming compliance with these standards serves as the acceptance criteria.

    Acceptance Criteria CategoryReported Device Performance Summary (Implicit Compliance)
    Electrical Safety (EMC)Compliant with IEC 60601-1-2
    General Safety and Essential PerformanceCompliant with IEC 60601-1, IEC 60601-1-11, IEC 60601-2-57 (for non-laser light source equipment), IEC 62471 (Photobiological safety)
    Battery SafetyCompliant with IEC 62133-2 (for Lithium systems)
    BiocompatibilityCompliant with ISO 10993-1, ISO 10993-5 (Cytotoxicity), ISO 10993-10 (Irritation and skin sensitization), ISO 10993-23 (Irritation)
    Software Verification and ValidationPerformed and documented per FDA guidance ("Content of Premarket Submissions for Device Software Functions - Guidance for Industry and Food and Drug Administration Staff"). Software considered "Basic Documentation Level," indicating malfunction would likely lead to minor injury.
    Usability ValidationCompliant with IEC 62366-1 and IEC 60601-1-6
    Irradiance & WavelengthWavelengths are specified (e.g., Red 630±10nm, Blue 415±10nm, Yellow 590±10nm, IR 830±10nm). Irradiance values are provided for different models and light modes (e.g., HD-59A Total: 75~115 mW/cm²). The document states, "Although the irradiance differs from ins within the acceptable deviation range; therefore, this difference will not raise any effectiveness issues." This implies the measured irradiance values fall within an accepted range for the intended effect.
    Treatment TimeSpecified as 2 minutes per treatment.
    Material/Design equivalenceMaterials comply with requirements. Housing materials differ from predicates but comply with requirements. Power source and treatment time slightly differ from predicates but comply with requirements.

    2. Sample sizes used for the test set and the data provenance

    The document primarily describes non-clinical performance testing (electrical safety, biocompatibility, software validation, usability validation). These tests are typically conducted on device prototypes or production samples rather than human test subjects in the context of a clinical study for AI model validation. Therefore, there isn't a "test set" in the sense of patient data.

    • Sample size for non-clinical tests: Not explicitly stated as a number of devices, but typically involves a limited number of test units to demonstrate compliance with standards.
    • Data Provenance: Not applicable in the context of patient data. The tests are performed on the device itself. The document mentions Shenzhen Nuon Medical Equipment Co., Ltd as the manufacturer in China, so the testing would likely have occurred there or at a certified lab contracted by them.
    • The document explicitly states: "Clinical testing was not needed for this 510(k). The non-clinical performance testing described above is sufficient to support that the device can be used safely and effectively." This confirms that no patient data was used for a clinical "test set."

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

    Not applicable. As clinical testing was not performed, there was no patient data requiring expert ground truth establishment for the test set.

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

    Not applicable. No clinical test set requiring adjudication of findings.

    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 direct-to-consumer cosmetic LED light therapy product, not an AI-assisted diagnostic or therapeutic device requiring MRMC studies for human reader performance.

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

    Not applicable. There is no AI algorithm in this device, as described, that would require standalone performance evaluation.

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

    Not applicable. For this specific device, "ground truth" refers to the established technical standards (e.g., IEC, ISO) and the device's ability to meet those specifications (e.g., emitting light at specified wavelengths and irradiance, safe electrical operation, biocompatible materials).

    8. The sample size for the training set

    Not applicable. This is not an AI/machine learning device; hence, there is no "training set."

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

    Not applicable. No training set for an AI model.

    Device Name :

    Medline ReNewal Reprocessed Abbott Inquiry Steerable Diagnostic Catheter

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    Medline ReNewal Reprocessed Abbott Inquiry Steerable Diagnostic Catheters can be used for electrogram recording and cardiac stimulation during diagnostic electrophysiologic studies. The catheters are commonly placed in the high right atrium, right ventricular apex, and the HIS bundle.

    Device Description

    The Medline ReNewal Reprocessed Inquiry Steerable Diagnostic Electrophysiology Catheters are flexible, insulated catheters constructed of thermoplastic elastomer material and noble metal electrodes. The tip of the steerable catheters may be manipulated with the control mechanism located in the handle of the proximal end of the catheter.

    AI/ML Overview

    The provided text is a 510(k) Premarket Notification from the FDA regarding a reprocessed medical device: the Medline ReNewal Reprocessed Abbott Inquiry Steerable Diagnostic Catheter. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving the safety and effectiveness of a novel device through extensive clinical studies with specific acceptance criteria as you would see for an AI/ML powered device.

    Therefore, the document does not contain the information requested regarding acceptance criteria, study details, sample sizes for training/test sets, expert adjudication, MRMC studies, standalone algorithm performance, or ground truth establishment in the context of an AI/ML device.

    Instead, the document details physical and functional performance testing to ensure the reprocessed device is equivalent to the original predicate devices. This typically involves:

    • Table of Acceptance Criteria and Reported Device Performance: This document does not present a formal table of acceptance criteria and reported device performance in the way one would for an AI/ML algorithm. Instead, it states that "The functional characteristics of the subject device have been evaluated and found to be substantially equivalent to the predicate device based on the following tests." The tests listed are:

      • Visual inspection
      • Dimensional measurement
      • Electrical safety
      • Mechanical characteristics (continuity, isolation, resistance)
      • Corrosion resistance
      • Cleaning validation
      • Biocompatibility
      • Packaging and shelf life validation
      • Sterilization validation
      • Product stability
        The acceptance criterion for these tests is that the reprocessed device performs comparably to the new, original predicate devices.
    • Sample size used for the test set and the data provenance: The document does not specify exact sample sizes for each of the non-clinical tests listed. It indicates the tests were performed on the reprocessed devices. The "data provenance" is implied to be from Medline ReNewal's internal testing of their reprocessed catheters. This is not medical imaging data from patients.

    • Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. For reprocessed medical devices, "ground truth" relates to engineering specifications and performance standards established by the original manufacturer and industry standards, rather than expert human interpretation of medical data.

    • Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. Adjudication methods are typically associated with human interpretation of complex data (like medical images) to establish ground truth, which is not the type of data or evaluation performed for this device.

    • 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 is a physical medical device, not an AI-powered diagnostic tool. MRMC studies are for AI/ML devices to assess human reader performance with and without AI assistance.

    • If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is a physical medical device, not an algorithm.

    • The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Ground truth for this device would be based on engineering specifications, material properties, functional performance benchmarks (e.g., electrical resistance within a specified range, mechanical integrity under stress, sterility), and established safety standards. It does not involve medical, pathological, or outcomes data in the way an AI/ML diagnostic would.

    • The sample size for the training set: Not applicable. This is not an AI/ML device, so there is no "training set."

    • How the ground truth for the training set was established: Not applicable. As there is no training set.

    In summary, the provided document is a 510(k) clearance letter for a reprocessed physical medical device, not an AI/ML enabled device. Therefore, the questions related to AI/ML model evaluation (training/test sets, ground truth methodology, expert adjudication, MRMC studies) are not relevant to this submission. The "study" proving the device meets acceptance criteria refers to a series of non-clinical, bench-top functional and material property tests to ensure the reprocessed device performs equivalently to its new predicate.

    ReNewal Reprocessed Biosense Webster Webster CS Catheter with EZ Steer Technology and Auto ID Technology

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    The Medline ReNewal Reprocessed Biosense Webster CS Catheter is indicated for electrophysiological mapping of cardiac structures, i.e., stimulation and recording only. The catheter is designed for use in the coronary sinus.

    Device Description

    The reprocessed catheters are diagnostic bi-directional 7F deflectable mapping electrophysiology EP catheters. The devices have the ability to map electrical activity within the Coronary Sinus (CS) through electrodes along the catheters' pre-shaped tip. The catheters have a braided bi-directional tip section that provides the user with two 180° opposed single plane curves (available curves are DF and FJ). The tip is deflected with a Rocker Lever, and the high torque shaft permits the tip's plane to rotate to ease accurate positioning of the catheter tip at the desired site. The Medline ReNewal Reprocessed Biosense Webster Webster CS Catheter with EZ Steer Technology and Auto ID are equipped with an Electronically Erasable Programmable Read Only Memory (EEPROM) that is used to store unique catheter identification information.

    AI/ML Overview

    The provided document is a 510(k) premarket notification from the FDA for a reprocessed medical device: "Medline ReNewal Reprocessed Biosense Webster CS Catheter with EZ Steer Technology and Medline ReNewal Reprocessed Biosense Webster Webster CS Catheter with EZ Steer Technology and Auto ID".

    This document is not about an AI/ML medical device. It's about a reprocessed catheter and demonstrates substantial equivalence to existing predicate devices based on non-clinical performance data. Therefore, the specific questions related to AI/ML device acceptance criteria, study methodologies (like MRMC, standalone performance, training sets, expert consensus for ground truth), and effect sizes of AI assistance are not applicable to this document.

    The document discusses "non-clinical testing" and "functional performance studies" for the reprocessed catheters to demonstrate their equivalence to new, original equipment manufacturer (OEM) catheters.

    Here's an attempt to extract the relevant information from the provided text, while noting the limitations regarding the AI/ML specific questions:

    Acceptance Criteria and Device Performance (based on non-clinical testing for a reprocessed device):

    The document does not provide a table of precise quantitative acceptance criteria with corresponding performance metrics for the reprocessed catheter in the way one would expect for an AI/ML device's diagnostic performance. Instead, it states that the functional characteristics of the subject device (reprocessed catheter) have been evaluated and found to be substantially equivalent to the predicate device. This substantial equivalence is based on various non-clinical tests.

    The types of non-clinical tests performed and implicitly, the areas where acceptance criteria would have been applied (though not explicitly listed with values), include:

    Test CategorySpecific Tests MentionedReported Performance (Qualitative, as quantitative data is not provided)
    Functional PerformanceSimulated use and artificial soilingFound to be substantially equivalent to the predicate device.
    MechanicalContinuity, isolation, resistance; corrosion resistanceFound to be substantially equivalent to the predicate device.
    CleaningProtein, total organic carbon, visual inspection under magnification; cleaning qualificationFound to be substantially equivalent to the predicate device.
    BiocompatibilityCytotoxicity; irritation; acute systemic toxicity; materials-mediated pyrogen; complement activation; hemolysis; coagulationFound to be substantially equivalent to the predicate device.
    SterilizationBioburden; ethylene oxide/ethylene chlorohydrin residuals; bacteriostasis/fungistasis; endotoxinFound to be substantially equivalent to the predicate device.
    OtherPackaging and shelf life validation; Product stabilityFound to be substantially equivalent to the predicate device.

    The evidence for "proof" that the device meets "acceptance criteria" is the FDA's determination of substantial equivalence (SE) to legally marketed predicate devices. This SE determination is based on the provided non-clinical testing data which, by inference, met the internal acceptance criteria set by Medline ReNewal and deemed sufficient by the FDA for establishing SE.


    Regarding the AI/ML specific questions:

    1. A table of acceptance criteria and the reported device performance: As explained above, for this reprocessed medical device, specific quantitative metrics are not provided in the summary. The acceptance is based on demonstrating substantial equivalence through various functional, mechanical, cleaning, biocompatibility, and sterilization tests.

    2. Sample sizes used for the test set and the data provenance: The document mentions "non-clinical testing data" and "functional performance studies" but does not specify the sample sizes (e.g., number of catheters tested) or the provenance (country of origin, retrospective/prospective) of this data. It is inherently laboratory/bench testing data, not clinical data from patients.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: This is not applicable. For a reprocessed physical device, "ground truth" would be established through laboratory methods and validated testing protocols against known engineering and biological standards, not through human expert consensus in the medical imaging sense.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable, as no expert adjudication of diagnostic outputs occurred.

    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 is a reprocessed physical catheter, not an AI/ML diagnostic algorithm.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is a physical device, not an AI algorithm. Its "standalone" performance would refer to its physical properties and functionality outside of human use, as evaluated through the non-clinical tests.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable in the context of diagnostic "ground truth" for AI. For this device, "ground truth" refers to the established performance and safety specifications of the original predicate device, against which the reprocessed device's performance is compared through physical and chemical testing.

    8. The sample size for the training set: Not applicable. This is a reprocessed physical medical device, not an AI/ML algorithm that undergoes "training."

    9. How the ground truth for the training set was established: Not applicable. No training set or ground truth in the AI/ML context exists for this device.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for reprocessed electrophysiology catheters, specifically the Medline ReNewal Reprocessed St. Jude Medical Response Electrophysiology Catheter and Supreme Electrophysiology Catheter.

    However, the document does not contain the detailed information necessary to complete the requested table and answer questions 2 through 9 regarding acceptance criteria, study data, sample sizes, ground truth establishment, or expert involvement for a medical device that uses an algorithm or AI.

    The document is a regulatory submission for reprocessed physical medical devices (catheters), not a study of an algorithmic or AI-based diagnostic/detection device. The "Non-clinical Testing Summary" section discusses functional performance, mechanical characteristics, corrosion resistance, cleaning, biocompatibility, packaging, shelf-life, and sterilization validation, which are typical for reprocessed physical medical devices.

    Therefore, I cannot extract the requested information as the context of the document does not align with the type of study and acceptance criteria you are asking about (i.e., for an AI/algorithm-based device).

    To summarize, the relevant information you requested is not present in the provided text because the document is about reprocessed physical medical devices, not an AI or algorithm-driven device.

It connects the catheter and console to provide a path of electrical transmission from the proximal end of an Achieve mapping catheter to standard shielded ECG pins that connect to standard EP pacing and recording equipment. The cable is designed to only be used with the Medtronic Achieve family of mapping catheters

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for a reprocessed medical device, the "Medline ReNewal Reprocessed Medtronic Achieve Catheter Connecting Cable (2ACHC)". It is fundamentally a comparison to a predicate device, arguing for substantial equivalence through non-clinical testing.

    However, the information provided does not contain details about acceptance criteria or a study proving device performance against such criteria in the context of an AI/algorithm-driven medical device.

    The document is a regulatory approval letter and a 510(k) summary for a reprocessed physical medical device (a cable), not an AI/software as a medical device (SaMD). Therefore, it does not include:

    • Acceptance criteria for an AI/algorithm's performance (e.g., sensitivity, specificity, AUC).
    • Details about a test set (sample size, provenance).
    • Information on expert ground truth establishment (number of experts, qualifications, adjudication methods).
    • Any multi-reader multi-case (MRMC) comparative effectiveness study.
    • Stand-alone algorithm performance.
    • Ground truth type for AI/algorithm evaluation.
    • Training set details for an AI model.

    The "Non-clinical Testing Summary" section describes the tests performed for this reprocessed physical device:

    • Functional performance: simulated use and artificial soiling; visual inspection; continuity, isolation and resistance device functionality; Electrical Safety current leakage and hipot
    • Cleaning Validation
    • Sterilization Validation bioburden testing
    • Packaging and shelf life validation
    • Product stability

    These are standard engineering and safety tests for a physical medical device, not performance evaluations for an AI/software.

    Therefore, based on the provided text, it is not possible to answer the detailed questions about acceptance criteria and study design for an AI/algorithm-driven medical device. The document simply isn't about that kind of device.
