    3-year Shelf Life ClaimSupported by accelerated aging (ASTM F1980-21) and package integrity/bench testing on aged devices.

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

    The document does not specify the exact sample sizes for the individual tests (e.g., number of devices tested for suction force, biocompatibility, etc.). It only states that "Physical bench testing was performed" and "The subject device test results were compared with the predicate device".

    Data Provenance: The manufacturing company is LI Medical Corporation LTD. in New Taipei City, Taiwan. The studies were likely conducted either internally by the manufacturer or by contract testing laboratories performing the specified ISO and ASTM standards. The data is retrospective in the sense that the tests were performed on finished devices to support the 510(k) submission.

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

    This question is not applicable to the "RELIEEV" Suction Curette as described in the document. This is a physical medical device, not a diagnostic device involving expert interpretation of data or images to establish a "ground truth" for a test set. The validation relies on objective physical, chemical, and biological testing standards.

    4. Adjudication method for the test set

    This question is not applicable. Adjudication methods (like 2+1, 3+1) are typically used for clinical studies involving human interpretation or subjective assessments, which are not detailed in this document for the provided device. The device validation relies on standardized tests with defined pass/fail criteria.

    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

    This question is not applicable. An MRMC study is relevant for diagnostic devices that involve human readers interacting with images or data, often in the context of AI assistance. The "RELIEEV" Suction Curette is a physical instrument for tissue sampling.

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

    This question is not applicable. This device is not an algorithm or software. It is a physical suction curette.

    7. The type of ground truth used

    This question is not directly applicable in the terms usually associated with AI/ML devices. For this physical device, "ground truth" is established through:

    • Physical measurements and functional performance standards: Defined by product specifications and comparing against the predicate device.
    • Standardized testing methods: Such as ISO and ASTM standards for biocompatibility, sterility, packaging, and shelf-life, which provide objective criteria for success or failure.
    • Analytical chemistry and microbiology results: For biocompatibility and sterility.

    8. The sample size for the training set

    This question is not applicable. There is no AI/ML component described for this device, therefore no "training set" in that context. The device is validated through traditional engineering, biological, and sterility testing.

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

    This question is not applicable, as there is no training set for an AI/ML algorithm for this physical device.

    AI/ML Overview

    The provided text describes the CrossGlide™ ETS, an Endometrial Tissue Sampler, and its submission for FDA 510(k) clearance. The document focuses on establishing substantial equivalence to a predicate device rather than presenting a standalone study with detailed acceptance criteria and performance data for the device itself.

    Based on the information provided, here's a breakdown of the requested elements:

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

    The document does not explicitly state quantitative acceptance criteria or a specific study that proves the device meets these criteria in the context of clinical performance (e.g., diagnostic accuracy or tissue yield). Instead, it lists various tests conducted to demonstrate substantial equivalence to a predicate device and safety/functionality.

    Acceptance Criteria CategoryReported Device Performance (Summary)
    BiocompatibilityMet ISO 10993-1, 10993-5:2009, 10993-10:2010 standards for cytotoxicity, vaginal irritation, and sensitization.

    Safety (General)Differences from predicate device not raising different questions of safety and effectiveness.
    Effectiveness (General)Differences from predicate device not raising different questions of safety and effectiveness.

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

    The document does not mention a clinical test set in the traditional sense of patient data for evaluating diagnostic or clinical performance. The "test sets" mentioned relate to engineering and safety validation:

    • Biocompatibility tests: Sample sizes are typically small and determined by the specific ISO standard. Data provenance is implied to be from laboratory testing performed by the manufacturer or contracted labs.
    • Sterilization validation: Sample sizes are determined by AAMI/ISO standards. Data provenance is from laboratory testing.
    • Packaging, Shipping, Shelf-Life & Device Functionality: Sample sizes are determined by specific ASTM guidance. Data provenance is from laboratory testing.
    • Functional testing (uterine model): The specific number of devices tested on the uterine model is not provided. Data provenance is from laboratory testing using a physical model, not human data.

    There is no mention of country of origin for any human data or whether studies were retrospective or prospective, as no human studies are described in detail.

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

    Not applicable. There is no described "test set" of patient cases requiring expert interpretation to establish ground truth for clinical performance. The ground truth for the engineering and safety tests would be defined by the specifications of the standards (e.g., whether a material is cytotoxic, whether a sterile barrier is maintained, whether a specific force is withstood).

    4. Adjudication method for the test set

    Not applicable. As no clinical test set requiring expert interpretation is described, no adjudication method is mentioned.

    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 an endometrial tissue sampler, a physical medical device for tissue collection, not an AI-powered diagnostic tool. Therefore, an MRMC study related to AI performance is irrelevant to this submission.

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

    Not applicable. This is not an algorithm or AI device.

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

    For the engineering and safety studies described:

    • Biocompatibility: Ground truth is against established limits and responses per ISO standards.
    • Sterilization: Ground truth is against sterility assurance levels (SALs) defined by AAMI/ISO standards, and residual limits.
    • Mechanical/Functional: Ground truth is against design specifications and functional requirements (e.g., maintaining negative pressure, correct deployment).
    • Uterine Model: Ground truth for comparison would be the ability to successfully deploy and collect "specimens" from the model as intended by the device design, presumably measured by quantitative factors or visual assessment of model interaction.

    8. The sample size for the training set

    Not applicable. This is not an AI/algorithm device that requires a training set.

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

    Not applicable.

    Summary Conclusion from the Document:

    The provided document (a 510(k) summary) focuses on demonstrating substantial equivalence of the CrossGlide™ ETS to a legally marketed predicate device (Marina Ampler (MAS), K021876). The "study" described is a collection of engineering and validation tests (biocompatibility, sterilization, packaging, shelf-life, and functional testing using a uterine model) to ensure the new device is safe and performs as intended, and that its differences from the predicate device do not raise new questions of safety or effectiveness. It does not present a clinical study with detailed acceptance criteria for diagnostic performance or tissue yield, as would be common for diagnostic AI tools.

The sealing ring ensures that the handle can be assembled closed with the barrel for keeping certain negative pressure.

    AI/ML Overview

    The provided text describes a 510(k) summary for a Disposable Endometrial Suction Curette (K102847). This submission is for a medical device that obtains tissue samples, and the regulatory review focuses on substantial equivalence to a predicate device rather than novel performance claims. As such, the information you're requesting regarding acceptance criteria from clinical studies as typically understood for AI/diagnostic algorithms is largely not applicable in this context.

    Here's an explanation based on the provided text:

    1. Table of acceptance criteria and the reported device performance:

    Acceptance Criteria CategorySpecific Criteria/TestsReported Device PerformanceComments
    Safety and Efficacy (General)"sufficient to ensure the efficacy and safety of the device for its intended use"Device determined to be "substantially equivalent" to predicate based on these tests.This is a blanket statement for the entire submission, not specific, quantifiable performance metrics for a diagnostic algorithm. The "efficacy" here refers to the device's ability to mechanically perform its function, not diagnostic accuracy.
    Physical CharacteristicsVisual InspectionPass (implied by substantial equivalence)Ensures product meets aesthetic and basic presentation standards.
    Dimensional SpecificationsDimensional TestsPass (implied by substantial equivalence)Confirms the physical dimensions of the device are as designed and comparable to the predicate.
    Functional PerformanceFunctional TestsPass (implied by substantial equivalence)The device must demonstrably perform its core function (e.g., generate negative pressure to draw samples). The text does not detail the specific functional tests or their results, but states they were developed and deemed sufficient.
    Biocompatibility (Implied)(Not explicitly stated in provided text, but generally required for medical devices coming into contact with human tissue)Pass (implied by substantial equivalence to a legally marketed device)This would involve tests to ensure the materials are non-toxic and do not cause adverse reactions.
    Sterility (Implied)(Not explicitly stated, but crucial for single-use devices intended for internal use)Pass (implied by the description "sterile disposable")Tests to ensure the device is free of microorganisms.
    Packaging & Labeling (Implied)(Not explicitly stated, but part of regulatory review)Pass (implied by FDA clearance)Ensuring correct labeling, instructions for use, and protection during transit.

    Important Note: The provided text does not include any acceptance criteria related to diagnostic accuracy, sensitivity, or specificity by comparing device output to a ground truth, which would typically be present for an AI-powered diagnostic device. This is because the device itself is a sampling tool, not a diagnostic algorithm. Its "performance" is about its ability to obtain a sample, not to interpret it.

    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

    • Sample Size for Test Set: Not applicable. The "tests" mentioned are primarily engineering and functional tests of the physical device, not clinical studies involving a patient test set in the way an AI diagnostic would have. No patient data or clinical samples are described as being used for the purpose of determining performance for this 510(k) submission.
    • Data Provenance: Not applicable.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

    • Number of Experts/Qualifications: Not applicable. There was no clinical ground truth established for a test set in the context of this device's performance evaluation for the 510(k) submission. The "ground truth" for the device's function would be its ability to physically collect a sample, which is assessed through engineering tests.

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

    • Adjudication Method: Not applicable. No clinical test set or subjective interpretations requiring adjudication were involved.

    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:

    • MRMC Study: No. This device is a physical sampling tool, not an AI or diagnostic algorithm that would assist human readers in interpretation. Therefore, an MRMC study is not relevant.

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

    • Standalone Performance: No. This is a physical medical device, not an algorithm.

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

    • Type of Ground Truth: Not applicable in the context of diagnostic performance. The "ground truth" for this device's function would be the successful collection of endometrial tissue, which is assessed through its mechanical and functional tests. The subsequent diagnostic examination of the collected specimen (e.g., for cancer) would use pathology as ground truth, but that is a downstream process performed by a lab, not part of this device's performance evaluation.

    8. The sample size for the training set:

    • Sample Size for Training Set: Not applicable. This is not an AI/machine learning device.

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

    • Ground Truth for Training Set: Not applicable.

    Summary of the Study (as described for this device):

    The "study" described for the Disposable Endometrial Suction Curette (K102847) is a non-clinical performance evaluation focused on engineering and functional testing, rather than a clinical trial measuring diagnostic accuracy.

    • Purpose: To demonstrate that the proposed device is substantially equivalent to a legally marketed predicate device (SelectCells™Mini, K974819).
    • Methodology:
      • "Tests have been developed which are considered sufficient to ensure the efficacy and safety of the device for its intended use."
      • These tests included:
        • Visual inspection: To confirm the device's physical appearance and integrity.
        • Dimensional checks: To ensure the device conforms to design specifications.
        • Functional tests: To verify that the device can perform its intended mechanical action (e.g., generating negative pressure to aspirate samples).
    • Key Finding: Based on these tests, the device was determined to be "substantially equivalent" to the predicate device. This means the FDA found that the new device is as safe and effective as the predicate device already on the market, despite not explicitly detailing all test results. The 510(k) process primarily relies on demonstrating equivalence rather than proving novel efficacy.

    In essence, this submission is for a physical instrument, and its "performance" means it works as intended mechanically to collect a sample, not that it interprets diagnostic information. Therefore, the types of detailed acceptance criteria, ground truth, and studies typically associated with AI/diagnostic algorithms are not documented in this 510(k) summary.

    AI/ML Overview

    The provided document set describes the Rocket Medical plc Endometrial Sampling Syringe, which was submitted for 510(k) clearance. This means the device demonstrated substantial equivalence to a predicate device already on the market, rather than proving its safety and effectiveness through extensive clinical trials for de novo approval. Therefore, the information requested regarding acceptance criteria, specific study designs, sample sizes, ground truth establishment, expert adjudication, and comparative effectiveness studies is largely inapplicable or not detailed in this specific submission.

    Here's an attempt to answer the questions based on the provided text, highlighting where information is not available due to the nature of a 510(k) submission focused on substantial equivalence:

    For a 510(k) submission, the "acceptance criteria" are typically related to demonstrating equivalence in design, materials, and intended use to a predicate device. "Reported device performance" in this context refers to the comparison against the predicate, primarily on physical characteristics.

    Acceptance Criteria (Implied for 510(k) Equivalence)Reported Device Performance (Rocket Endometrial Sampling Syringe compared to Unimar Endometrial Pipelle)
    Design and Dimensional Equivalence:
    Outer Sheath Overall Length26mm
    Outer Sheath Outer Diameter3.1 od
    Outer Sheath Inner Diameter-- (Not directly comparable)
    Outer Sheath Graduations6-14cm
    Sampling Hole Size2mm
    Sampling Hole Bevel AnglePerpendicular punch
    Sampling Hole Location5mm from distal end
    Inner Piston Initial Position233mm
    Material Equivalence:(Implied as comparable, but not explicitly stated materials)
    Intended Use Equivalence:Matches Indications for Use of predicate device
    Functional Equivalence (implied for biopsy efficacy):"Gives good suction and when combined with the shape and form of the curette opening gives good sample extraction."
    Flexural Properties:"comparable with the Unimar Endometrial Pipelle"

    2. Sample sizes used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    • Sample Size: Not applicable. The submission states, "The device has yet to be clinically evaluated but has been subjected to a real laboratory performance testing against competitor product." This indicates in vitro or bench testing, not human subject testing with a "test set" in the sense of clinical data. There is no information on the number of samples used in this laboratory testing.
    • Data Provenance: The device is manufactured by Rocket Medical plc in Tyne & Wear, England. The laboratory performance testing would have been conducted internally or by a contracted lab. The data is likely non-clinical/bench test data, not patient data.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

    Not applicable. As described, no clinical "test set" with human subjects requiring expert ground truth establishment was used for this 510(k) submission. The evaluation was laboratory-based comparison to a predicate device.

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

    Not applicable. No clinical "test set" with human subjects requiring adjudication was used.

    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 an endometrial sampling syringe, not an AI-assisted diagnostic tool or a device that impacts human reader performance. No MRMC study was performed.

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

    Not applicable. This is a medical device (syringe), not an algorithm or AI system.

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

    Not applicable. For the in vitro or bench testing, the "ground truth" would be the measurable physical and functional specifications of the predicate device, against which the new device was compared. For example, comparing the actual sampling hole size of the Rocket syringe to the stated size of the Unimar Pipelle. There's no pathological, outcomes, or expert consensus ground truth mentioned for this type of submission.

    8. The sample size for the training set

    Not applicable. This is a medical device, not an AI or machine learning model that requires a training set.

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

    Not applicable. As above, this is not an AI/ML device.

    Device Description

    The ETO sterilized MAS w/ Syringe is used to obtain a sample of differential endometrial tissue. The MAS w/ syringe is a 3mm (O.D.) endometrial suction device that has a Randall-like cutting edge at its distal end and is packaged with a twist-and-lock syringe. The syringe will provide a vacuum or suction during the procedure. The MAS w/ syringe is sterile unless the package is opened or damaged and designed for single patient use only.

    The ETO sterilized MAS without syringe is used to obtain a sample of differential endometrial tissue. The MAS is a m 3.5mm (O.D.) endometrial suction curette that has a fenestration on the wall at its distal end and a tight fitting piston that will provide a vacuum or suction during the procedure as it is pulled proximally. The MAS is sterile unless the package is opened or damaged and designed for single patient use only.

    AI/ML Overview

    The provided text describes a 510(k) summary for the "Marina Ampler Sampler (MAS) with and without syringe," which is an endometrial suction curette. The document aims to demonstrate substantial equivalence to a predicate device, the "Curelle from Bioteque Corporation" (510k #K915491).

    However, the submission does not contain acceptance criteria for a device's performance that would require a study to prove it meets those criteria. Instead, it focuses on demonstrating substantial equivalence in technological characteristics to a legally marketed predicate device.

    Therefore, the requested information cannot be fully provided as it pertains to a different type of validation and performance evaluation than what is presented in this 510(k) summary.

    Here's an breakdown of why the requested information isn't available in this document:

    1. Acceptance criteria and reported device performance (Table): Not applicable. This document is a 510(k) summary for a Class II device, where the primary goal is to show the new device is as safe and effective as a predicate device, not necessarily to meet specific, quantifiable performance thresholds with a new, standalone study. The table provided (paragraph 14) compares technological characteristics to the predicate device, not performance against pre-defined acceptance criteria. The performance is stated as "Identical" to the predicate.

    2. Sample size, data provenance for test set: Not applicable. No clinical outcome or diagnostic performance test set is described. The comparison is based on design, materials, and intended use as compared to the predicate device.

    3. Number of experts and qualifications for ground truth: Not applicable. Ground truth, as typically used in the context of diagnostic accuracy studies (e.g., for AI/imaging devices), is not established or discussed here.

    4. Adjudication method: Not applicable. No test set requiring expert adjudication for ground truth is present.

    5. Multi-reader multi-case (MRMC) comparative effectiveness study: Not applicable. This is a medical device (endometrial suction curette), not an AI/imaging diagnostic device that would typically undergo such a study to evaluate human reader improvement with AI assistance.

    6. Standalone (algorithm only) performance: Not applicable. This device is a manual medical instrument not an algorithm.

    7. Type of ground truth used: Not applicable. As explained above, ground truth in the context of performance evaluation of diagnostic algorithms is not part of this submission. The "ground truth" for this 510(k) is the established safety and effectiveness of the predicate device.

    8. Sample size for training set: Not applicable. This is not an AI/machine learning device. No training set is involved.

    9. How ground truth for training set was established: Not applicable.

    Summary of Device Equivalence (from Paragraph 14):

    The submission demonstrates substantial equivalence by comparing the Marina Ampler Sampler (MAS) with and without syringe to the predicate device, Curelle from Bioteque Corporation (510k #K915491), based on technological characteristics.
