    AI/ML Overview

    This document is a 510(k) Premarket Notification for a medical device (hip prosthesis). It does not contain information about an AI/ML-driven medical device or a study involving AI/ML performance. Therefore, it is impossible to extract the requested information regarding acceptance criteria and study details for an AI-driven device.

    The document primarily focuses on demonstrating substantial equivalence of a new size of a Quadra-P hip prosthesis to previously cleared versions and other predicate devices. The "Performance Data" section details non-clinical mechanical studies (fatigue tests, range of motion, pull-off force, coating tests, pyrogenicity) conducted on the physical device, not on an algorithm's performance. It explicitly states: "No clinical studies were conducted."

    To answer the user's request, I would need a document describing the validation of an AI/ML-driven medical device.

    AI/ML Overview

    This is a 510(k) premarket notification for the "SMS Cementless Stem" (K201673), a hip prosthesis. The document details the device, its intended use, and a comparison to predicate devices, along with performance data.

    Here's an analysis of the provided text in relation to your request:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document outlines various non-clinical performance tests conducted for the SMS Cementless Stem. However, it does not provide specific acceptance criteria values or the quantitative results of these tests in a table format. It only states that the testing was conducted "according to written protocols with acceptance criteria that were based on standards."

    Here's what can be inferred for a table, but actual criteria values and results are missing in the document:

    Test (Standard)Acceptance Criteria (Not provided explicitly, generally "meet standard requirements")Reported Device Performance (Not provided explicitly, implied "met criteria")
    Range of Motion (EN ISO 21535:2009)Based on standard EN ISO 21535:2009Conducted
    Fatigue Testing - Stemmed Femoral Components (ISO 7206-4:2010 + AME 1:2016)Based on standard ISO 7206-4Conducted
    Fatigue Testing - Head and Neck Region of Stemmed Femoral Components (ISO 7206-6:2013)Based on standard ISO 7206-6Conducted
    Pull-off Force Testing - Taper Connections (ASTM F2009-00 (Reapproved 2011))Based on standard ASTM F2009-00Conducted
    Coating Tests - Hydroxyapatite (ISO 13779-1:2008)Based on standard ISO 13779-1Conducted
    Coating Tests - Tension Testing of Calcium Phosphate and Metal Coatings (ASTM F1147-99)Based on standard ASTM F1147-99Conducted

    Pyrogenicity - Pyrogen Test (USP chapter )Based on USP chapterConducted

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

    The document explicitly states: "No clinical studies were conducted." Therefore, there is no test set in the context of human clinical data or patient outcomes. The "performance data" refers to non-clinical mechanical and material tests. The sample sizes for these mechanical tests are not provided in this summary. Data provenance is not applicable here as no human data was used.

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

    Not applicable as no clinical studies were conducted and no ground truth in the clinical sense was established. The "ground truth" for the non-clinical tests would be the specifications and requirements of the referenced ISO and ASTM standards.

    4. Adjudication Method for the Test Set

    Not applicable as no clinical studies were conducted which would require adjudication of expert opinions or outcomes.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and its effect size

    No MRMC study was mentioned or performed, as "No clinical studies were conducted." This device is a mechanical implant, not an AI or diagnostic tool that would typically undergo MRMC studies.

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

    Not applicable. This device is a hip implant, not an algorithm or AI system.

    7. The Type of Ground Truth Used

    For the non-clinical performance and coating tests, the "ground truth" implicitly refers to the
    requirements and specifications outlined in the referenced international standards (ISO and ASTM) and the European Pharmacopoeia/USP chapters. The device is expected to meet these pre-defined engineering and material standards. This is a form of engineering/material specification compliance as ground truth.

    8. The Sample Size for the Training Set

    Not applicable. This device is a mechanical implant, 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 there is no training set for this type of medical device's approval.

    AI/ML Overview

    This document describes the premarket notification (510(k)) for the SMS Femoral Stem, a cementless bone-preserving short stem designed for proximal fixation in total or partial hip arthroplasty.

    Here's an analysis of the provided text in relation to acceptance criteria and supporting studies, though it's important to note that this is a medical device submission, not an AI/ML device submission, so the questions regarding human readers, training sets, etc., are not directly applicable here. The document focuses on mechanical performance and biocompatibility for a physical implant.

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

    The document lists performance tests and the standards they adhere to, implying that meeting these standards constitutes the acceptance criteria. However, it does not explicitly state numerical acceptance criteria and does not present specific performance data values in a table format. It merely states that "Testing was conducted according to written protocols with acceptance criteria that were based on standards." and that the studies "demonstrated substantial equivalence."

    Here's a generalized representation based on the provided information:

    Acceptance Criterion (Implicit)Reported Device Performance
    Conformance to EN ISO 21535:2009 (Range of Motion)Testing conducted, supporting substantial equivalence.
    Conformance to ISO 7206-4:2010 (Fatigue Testing - Stem)Testing conducted, supporting substantial equivalence.
    Conformance to ISO 7206-6:2013 (Fatigue Testing - Head/Neck)Testing conducted, supporting substantial equivalence.
    Conformance to ISO 7206-10:2003 (Static Fatigue - Modular Heads)Testing conducted, supporting substantial equivalence.
    Conformance to ASTM F2009-00 (Axial Disassembly Force)Testing conducted, supporting substantial equivalence.
    Conformance to ISO 13779-1:2008 (Coating - Hydroxyapatite)Testing conducted, supporting substantial equivalence.
    Conformance to ASTM F1147-99 (Tension Testing - Coatings)Testing conducted, supporting substantial equivalence.
    Conformance to European Pharmacopoeia §2.6.14/USP (BET)Testing conducted (LAL test), supporting substantial equivalence.
    Conformance to USP (Pyrogen Test)Testing conducted, supporting substantial equivalence.

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

    The document lists various non-clinical mechanical and coating tests, which typically involve physical samples of the device components. It does not specify the sample sizes (number of stems tested for fatigue, etc.) for each test. The provenance of the data is implicit: it's generated from laboratory testing of the device components. There is no clinical data or patient-derived data mentioned.

    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)

    This question is not applicable to this type of medical device submission. Ground truth and expert adjudication are relevant for AI/ML diagnostic devices, not for physical implants that undergo mechanical and material testing. The "ground truth" for these tests are the established scientific principles and measurement techniques outlined in the specified ISO and ASTM standards.

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

    This question is not applicable for the same reasons as #3. Mechanical testing results are typically objectively measured and evaluated against a standard, not subject to expert adjudication in the same way as diagnostic interpretations.

    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 as this is not an AI/ML device. No MRMC study was conducted.

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

    This question is not applicable as this is not an AI/ML device.

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

    For the non-clinical tests, the "ground truth" is defined by the specifications and acceptable ranges outlined in the referenced international (ISO) and American (ASTM) standards. For instance, a fatigue test determines if the device can withstand a certain number of cycles at a specific load without failure, as per the standard's requirements. Pyrogenicity is determined by established biological testing methods (LAL test, USP pyrogen test).

    8. The sample size for the training set

    This question is not applicable as this is not an AI/ML device. There is no concept of a "training set" for a physical implant undergoing mechanical and material characterization.

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

    This question is not applicable as this is not an AI/ML device.

    AI/ML Overview

    This document is a 510(k) premarket notification for the "Quadra-P" hip prosthesis, specifically describing the physical and mechanical testing performed to demonstrate substantial equivalence to previously cleared predicate devices. It does not contain information about the performance or acceptance criteria of an AI/Software device, nor does it describe a study involving humans or the establishment of ground truth for such a device.

    Therefore, I cannot extract the information required to answer your questions about acceptance criteria and studies proving the device meets those criteria, as the provided document pertains to a physical medical device (hip prosthesis) and its mechanical engineering performance tests, not an AI or software-based medical device.

    The document discusses:

    • Device Name: Quadra-P (hip prosthesis)
    • Regulation Number: 21 CFR 888.3353 (Hip Joint Metal/Ceramic/Polymer Semi-Constrained Cemented Or Nonporous Uncemented Prosthesis)
    • Performance Data (Non-Clinical Studies):
      • Range of Motion (ROM) testing (EN ISO 21535:2009)
      • Fatigue testing (ISO 7206-4 and ISO 7206-6)
      • Pull off force testing (ASTM F2009-00)
      • Pyrogenicity testing (European Pharmacopoeia §2.6.14/USP and USP )
    • Clinical Studies: "No clinical studies were conducted."

    Since the request is specifically about a device proving it meets acceptance criteria through a study involving a test set, expert ground truth, adjudication methods, and potentially human readers (which implies an AI/Software device or diagnostic device), the provided text is entirely irrelevant to those questions.

    The instruments used with the AMIStem-H Proximal Coating stems were previously cleared as part of the AMIStem Implants family (K093944, K103189, and K121011). Additional instrumentation, included within the subject 510(k), can be used in lieu of the previously cleared instruments.

    AI/ML Overview

    The provided document describes a 510(k) premarket notification for a hip prosthesis, the AMIStem-H Proximal Coating. This is a medical device traditionally regulated and does not fall under the purview of AI/ML-driven software as a medical device (SaMD). Therefore, the concepts of acceptance criteria, test sets, ground truth establishment, training sets, and MRMC studies, which are pertinent to validating performance of AI/ML models, do not apply to this document.

    The document details the device's indications for use, material composition, design similarities, and differences to predicate devices, and the non-clinical studies conducted to support its substantial equivalence. These non-clinical studies primarily focus on mechanical and material performance rather than diagnostic accuracy or AI model performance.

    Therefore, I cannot extract the requested information about acceptance criteria for AI/ML performance, sample sizes for AI test/training sets, expert consensus, adjudication methods, or MRMC studies, as these aspects are not relevant to the evaluation of this traditional medical device.

    The closest analogue to "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context would be:

    Acceptance Criteria (General to the Device Type):

    • Mechanical Integrity: The device must withstand anticipated physiological forces over its design life without fracture or significant deformation.
    • Biocompatibility: The materials used must be safe for implantation in the human body.
    • Coating Adhesion: The coating must adhere sufficiently to the substrate.
    • Sterility: The device must be provided sterile.
    • Fatigue Life: The device must demonstrate sufficient resistance to fatigue failure.

    Study Proving Acceptance (from the document):
    The document lists the following non-clinical studies that aim to demonstrate these general acceptance criteria:

    • Fatigue testing: In accordance with ISO 7206-4:2010 and ISO 7206-6:1992.
    • Range of Motion Analysis: In accordance with EN ISO 21535:2009 (specifically Tilting and Rotation Stability).
    • Pull Off Testing: In accordance with ASTM F2009-00 (likely for coating adhesion).
    • Coating Tests: To evaluate coating properties.
    • Cleaning and Sterilization Validation: To ensure the device can be properly sterilized.
    • Bacterial endotoxin testing: To ensure it meets pyrogenicity standards.
    • Shelf-life studies: To determine the stability of the device over time.

    No human reader studies, AI model performance metrics, or related data are presented in this document.
