    Device Description

    Materialise Shoulder System™ is a patient-specific medical device that is designed to be used to assist the surgeon in the placement of shoulder components during total anatomic and reverse shoulder replacement surgery. This can be done by generating a pre-surgical shoulder plan and, if requested by the surgeon, by manufacturing a patient-specific glenoid guide and models to transfer the glenoid plan to surgery. The device is a system composed of the following:

    • a software component, branded as SurgiCase Shoulder Planner. This software is a planning tool used . to generate a pre-surgical plan for a specific patient.
    • Materialise Shoulder Guide and Models, which are a patient-specific quide and models that are based ● on a pre-surgical plan. This pre-surgical plan is generated using the software component. Patientspecific glenoid guide and models will be manufactured if the surgeon requests patient-specific guides to transfer the glenoid plan to surgery. The Materialise Shoulder Guide is designed and manufactured to fit the anatomy of a specific patient. A bone model of the scapula is delivered with the Materialise Shoulder Guide. A graft model can be delivered with the Materialise Shoulder Guide. The graft model visualizes the graft-space between implant and bone, based on the pre-operative planning of the surgeon. The graft model serves as a visual reference for the surgeon in the OR.
    AI/ML Overview

    The provided FDA 510(k) summary (K242813) for the Materialise Shoulder System™ describes a submission seeking substantial equivalence to a previously cleared device (K241143). This submission is primarily for adding compatibility with new implant components rather than introducing a completely new AI capability or significant software change that would necessitate extensive new performance data. Therefore, the document does not contain the detailed information typically found in a study proving a device meets acceptance criteria for an AI/ML product.

    Specifically, the document states:

    • "The non-clinical performance data has demonstrated that the subject software technological differences between the subject and predicate devices do not raise any different questions of safety and effectiveness." (Page 9)
    • "Software verification and validation were performed, and documentation was provided following the 'Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.' This includes verification against defined requirements, and validation against user needs." (Page 10)
    • "Previous testing for biocompatibility, sterility, cleaning, debris, dimensional stability and packaging are applicable to the subject device. Testing verified that the accuracy and performance of the system is adequate to perform as intended. The stability of the device placement, surgical technique, intended use and functional elements of the subject device are the same as that of the predicate device of Materialise Shoulder System™ K241143 and previously cleared devices... therefore previous simulated surgeries using rapid prototyped bone models and previous cadaver testing on previously cleared devices K153602 and K131559 are considered applicable to the subject device." (Page 10)

    Given this, I cannot provide detailed answers to many of your questions as the submission relies on the substantial equivalence principle and prior testing rather than new, extensive performance studies for AI/ML.

    However, I can extract what is available:

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

    The document does not provide a specific table of quantitative acceptance criteria and reported device performance for the current submission (K242813), as it relies on the previous clearance and the assessment that the changes (adding implant compatibility) do not raise new safety or effectiveness concerns.

    The general acceptance criterion mentioned is that the "accuracy and performance of the system is adequate to perform as intended." This was verified through previous testing, including "simulated surgeries using rapid prototyped bone models and previous cadaver testing."

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

    The document mentions "previous simulated surgeries using rapid prototyped bone models and previous cadaver testing on previously cleared devices K153602 and K131559." It does not specify the sample size for these tests, nor the country of origin of the data or whether it was retrospective or prospective.

    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 information is not provided in the document.

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

    This information is not provided in the document.

    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

    No such MRMC study is mentioned. The device is a "pre-surgical planner" and "surgical instrument" designed to assist the surgeon, but the provided text does not detail comparative effectiveness studies of human readers (surgeons) with and without the AI (planning software) assistance.

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

    The software (SurgiCase Shoulder Planner) generates a pre-surgical plan which the "qualified surgeon" can "visualize, measure, reconstruct, annotate, edit and approve" (Page 9). This indicates a human-in-the-loop process. Standalone performance of the algorithm without human interaction is not discussed as it's not the intended use.

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

    The document generally refers to "verification against defined requirements, and validation against user needs" and "accuracy and performance of the system is adequate to perform as intended" based on "simulated surgeries using rapid prototyped bone models and previous cadaver testing." This suggests a ground truth established through expert-defined surgical planning parameters and comparison to physical outcomes in the simulated/cadaveric environment, but specifics on how this ground truth was formalized (e.g., expert consensus on optimal planning, precise measurement validation) are not detailed.

    8. The sample size for the training set

    This device is a surgical planning tool and guides, not a deep learning AI model that requires a "training set" in the conventional sense for image classification or similar tasks. It is based on algorithms that process CT-imaging scans and anatomical landmarks to generate personalized plans and guides. Therefore, the concept of a "training set" for AI/ML is not applicable here in the way it would be for a pattern recognition AI. The software's robustness and accuracy are likely validated through extensive testing against various patient anatomies and surgical scenarios.

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

    As explained above, the concept of a training set as typically understood for AI/ML models is not directly applicable to this device based on the provided information.

    AI/ML Overview

    The provided text describes a 510(k) submission for the Materialise Shoulder System™, Materialise Shoulder Guide and Models, and SurgiCase Shoulder Planner. It indicates that this is a special 510(k) submission, meaning it's for a modification to a previously cleared device. Therefore, much of the performance data refers back to the predicate device and prior clearances.

    Here's an analysis of the acceptance criteria and supporting study information based on the provided text:

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

    The document does not explicitly state quantitative acceptance criteria or a direct table showing "acceptance criteria vs. reported device performance" for this specific 510(k) submission. Instead, for this special 510(k), the performance data mainly focuses on demonstrating that the changes (addition of new implant components to the software and hardware compatibility) do not raise new questions of safety and effectiveness compared to the predicate device.

    The "performance data (non-clinical)" section highlights that:

    • Hardware: Previous testing for biocompatibility, cleaning, debris, dimensional stability, and packaging is applicable. Accuracy and performance of the system were "adequate to perform as intended." Previous simulated surgeries and cadaver testing on earlier cleared devices are considered applicable.
    • Software: Software verification and validation were performed "against defined requirements" and "against user needs," following FDA guidance.

    Since this is a special 510(k) for an incremental change (adding compatibility with specific new implants), it's implied that the acceptance criteria are met if these additions do not negatively impact the established safety and effectiveness of the existing device, and the software development process meets regulatory standards.

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

    • Hardware (previous testing cited): The document mentions "previous simulated surgeries using rapid prototyped bone models" and "previous cadaver testing on previously cleared devices K153602 and K131559." It does not specify the sample size for these previous studies (e.g., number of bone models or cadavers) or their provenance (country of origin), nor does it state if they were retrospective or prospective.
    • Software (verification and validation): The document states "Software verification and validation were performed," but does not specify a separate "test set" in the context of clinical data or specific performance metrics with sample sizes for this particular submission. The V&V activities would involve testing against requirements and user needs, which could include various test cases and scenarios, but these are not quantified here as a "test set" size.

    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 information is not provided in the document. The studies cited for hardware ("simulated surgeries" and "cadaver testing") and software ("verification and validation") do not detail the involvement of experts in establishing ground truth, their number, or specific qualifications. The software's function is to assist surgeons in planning, implying surgeon input in its use, but not explicitly in establishing a ground truth for a test set described in this submission.

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

    This information is not provided in the document.

    5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    The document does not mention any MRMC comparative effectiveness studies. The device (SurgiCase Shoulder Planner software component and Materialise Shoulder Guide and Models hardware component) is designed to assist surgeons in planning and component positioning, but the provided text does not contain data on whether human readers/surgeons improve with or without this specific AI assistance or effect sizes.

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

    The document states that the SurgiCase Shoulder Planner is "intended to be used as a pre-surgical planner for simulation of surgical interventions for shoulder orthopedic surgery. The software is used to assist in the positioning of shoulder components." It also mentions, "SurgiCase Shoulder Planner allows the surgeon to visualize, measure, reconstruct, annotate and edit pre-surgical plan data." This indicates that the software is a human-in-the-loop device, where the surgeon is actively involved in the planning process and responsible for approving the plan. Therefore, a standalone (algorithm only) performance assessment, without human input, is unlikely to be the primary method of evaluation described or required for this type of device. The document does not provide such standalone performance data.

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

    The document does not explicitly state the type of ground truth used for any specific test set related to this submission. For the hardware (guides and models), the "accuracy and performance" implies a comparison to a known standard or ideal, perhaps derived from anatomical models or surgical goals. For the software, "verification against defined requirements, and validation against user needs" suggests that the ground truth for V&V would be the successful adherence to these requirements and user expectations, which could involve internal expert review or adherence to pre-defined medical/engineering specifications. However, specific types of ground truth like pathology or long-term outcomes data are not mentioned.

    8. The sample size for the training set

    This information is not provided in the document. As the submission is for a special 510(k) updating compatibility, it's possible that the core algorithms were developed and trained previously, and details of their original training are not part of this specific submission. The focus here is on the impact of the changes to the device.

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

    This information is not provided in the document. Similar to the training set size, the specifics of how the ground truth was established for the original training of any underlying algorithms are not included in this special 510(k).

    AI/ML Overview

    The provided text describes the regulatory clearance for the Materialise Shoulder System™ and mentions performance data, but it does not contain a detailed study proving the device meets specific acceptance criteria in the format requested.

    The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting a comprehensive standalone study with detailed effectiveness metrics.

    Here's an analysis of the information that can be extracted, and what is missing based on your request:

    1. Table of Acceptance Criteria and Reported Device Performance:

    • Acceptance Criteria: Not explicitly stated in a quantitative manner for the performance of the AI component (SurgiCase Shoulder Planner) or the hardware (Materialise Shoulder Guide and Models) beyond ensuring it performs "as intended" and maintains accuracy.
    • Reported Device Performance: The document states that "Testing verified that the accuracy and performance of the system is adequate to perform as intended." However, no specific performance metrics (e.g., accuracy, precision, sensitivity, specificity, or error margins) are provided for either the software for planning or the hardware for guiding.

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

    • Test Set Sample Size: Not specified for the software component (SurgiCase Shoulder Planner).
    • Data Provenance: Not specified for any software testing.
    • For Hardware: It refers to "simulated surgeries using rapid prototyped bone models and previous cadaver testing." No specific number of models or cadavers is provided, nor is the country of origin or whether it was retrospective or prospective.

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

    • Number of Experts: Not specified.
    • Qualifications of Experts: Not specified.

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

    • Not specified.

    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:

    • No MRMC study is mentioned. The document focuses on the planning and guidance aspect for surgeons, but not on a comparative study of human readers (surgeons) with and without AI assistance for diagnosis or planning accuracy.

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

    • A standalone performance evaluation of the software's planning functionality is implied through the statement "Software verification and validation were performed, and documentation was provided following the 'Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.'" However, no specific metrics or study details are provided. The software is described as a "planning tool used to generate a pre-surgical plan" and for "assisting the surgeon in positioning shoulder components," suggesting a human-in-the-loop workflow.

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

    • Ground Truth Type: Not explicitly stated for the software. For the hardware, the use of "rapid prototyped bone models and previous cadaver testing" implies a physical ground truth for accuracy validation.

    8. The sample size for the training set:

    • The document does not mention a training set sample size, which is typical for AI/ML models. This suggests the software functionality described (planning, visualization, measurement) might not be based on deep learning/machine learning that requires explicit training data in the same way as, for example, an image classification algorithm. It seems to be a rules-based or physics-based planning software.

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

    • As no training set is mentioned, the method for establishing its ground truth is also not provided.

    In summary:

    The provided text from the FDA 510(k) summary states that non-clinical performance testing indicates the device is as safe and effective as its predicate. It mentions software verification and validation and previous hardware testing (biocompatibility, sterility, cleaning, debris, dimensional stability, packaging, simulated surgeries, cadaver testing). However, it lacks the specific quantitative acceptance criteria and detailed study results (such as sample sizes, expert qualifications, clear performance metrics, ground truth establishment for software, and formal comparative effectiveness study results) that are typically expected when describing a study proving specific acceptance criteria in detail. This information is usually found in separate, more detailed technical documentation submitted to the FDA, not in the public 510(k) summary.

    AI/ML Overview

    This document is a 510(k) premarket notification for the Materialise Shoulder System™, Materialise Shoulder Guide and Models, and SurgiCase Shoulder Planner. It asserts substantial equivalence to a previously cleared predicate device (K220452).

    The provided text does not contain detailed acceptance criteria or the specific study that proves the device meets those criteria for the software component (SurgiCase Shoulder Planner) in the context of AI/ML performance metrics.

    The document primarily focuses on demonstrating substantial equivalence based on:

    • Intended Use: The device is a patient-specific medical device to assist in shoulder component placement during total anatomic and reverse shoulder replacement surgery. The software component, SurgiCase Shoulder Planner, is a pre-surgical planner for simulation and assistance in positioning shoulder components.
    • Technological Characteristics: The subject device has similar fundamental technologies, device functionality, and software technology (same code base, design, verification, and validation methods) as the predicate device.
    • Performance Data (Non-Clinical):
      • Hardware: States previous testing for biocompatibility, cleaning, debris, dimensional stability, and packaging are applicable and demonstrate substantial equivalence. Mentions testing verified accuracy and performance, and applicability of simulated surgeries and cadaver testing from previous clearances.
      • Software: States that "Software verification and validation were performed, and documentation was provided following the 'Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.' This includes verification against defined requirements, and validation against user needs."

    Therefore, it is not possible to extract the requested information regarding AI/ML-specific acceptance criteria and performance study details from this document. The document describes a traditional 510(k) clearance process, not one with specific AI/ML performance metrics as would be expected for an AI-driven diagnostic or prognostic device. The software "assists" in planning and visualization, it does not appear to perform automated diagnostic or prognostic functions for which detailed performance metrics (like sensitivity, specificity, AUC) would typically be required for FDA clearance.

    Based on the provided text, I can only provide the following information as much as possible:

    1. A table of acceptance criteria and the reported device performance:
    * Acceptance Criteria: Not explicitly stated in the document in terms of quantitative performance metrics for the software's "assistance" function. The acceptance criteria seem to be related to demonstrating substantial equivalence in intended use, technological characteristics, and non-clinical performance (including verification and validation against defined requirements and user needs for the software).
    * Reported Device Performance:
    * Hardware: "Testing verified that the accuracy and performance of the system is adequate to perform as intended." No quantitative metrics are provided.
    * Software: "Software verification and validation were performed... This includes verification against defined requirements, and validation against user needs." No quantitative metrics are provided. The document highlights that the software technology differences (addition of one implant component, easier visualization of muscle elongation) "do not affect the safety or effectiveness, or that they do not raise any new issues regarding to the safety and effectiveness compared to the predicate device."

    2. Sample size used for the test set and the data provenance:
    * Sample Size: Not specified for software performance validation.
    * Data Provenance: Not specified.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
    * Not specified. The software is a planning tool to which a surgeon provides input and approves. Ground truth in the context of AI/ML models (e.g., for diagnosis) is not applicable here as the software's function is not a diagnostic one based on the description.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
    * Not applicable as no such study is described for the software.

    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 described. The software's role is described as assisting in planning and visualization, not as an AI providing interpretations that would be compared to human readers.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
    * Not applicable. The software is explicitly described as a "pre-surgical planner" that "allows the surgeon to visualize, measure, reconstruct, annotate and edit pre-surgical plan data." It's a human-in-the-loop system for planning, not a standalone diagnostic algorithm.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
    * Not applicable in the AI/ML diagnostic sense. The "ground truth" for the software's functionality would be its adherence to specified design requirements and user needs, ensuring it accurately represents anatomical structures and allows for proper planning as intended, rather than a clinical ground truth for a diagnostic output.

    8. The sample size for the training set:
    * Not specified. The document does not describe a machine learning model that would require a distinct training set in the conventional sense. The "training" for such software would typically involve its development and internal testing against requirements.

    9. How the ground truth for the training set was established:
    * Not applicable, as no external training set with established ground truth (e.g., clinical labels) is mentioned for a machine learning model.

    Device Description

    Materialise Shoulder System™ is a patient-specific medical device that is designed to be used to assist the surgeon in the placement of shoulder components during total anatomic and reverse shoulder replacement surgery. This can be done by generating a pre-surgical shoulder plan and, if requested by the surgeon, by manufacturing a patient-specific glenoid guide and models to transfer the glenoid plan to surgery. The device is a system composed of the following: a software component, branded as SurgiCase Shoulder Planner. This software is a planning tool used to generate a pre-surgical plan for a specific patient. Materialise Shoulder Guide and Models, which are a patient-specific guide and models that are based on a pre-surgical plan. This pre-surgical plan is generated using the software component. Patient-specific glenoid guide and models will be manufactured if the surgeon requests patient-specific guides to transfer the glenoid plan to surgery. The Materialise Shoulder Guide is designed and manufactured to fit the anatomy of a specific patient. A bone model of the scapula is delivered with the Materialise Shoulder Guide. A graft model can be delivered with the Materialise Shoulder Guide. The graft model visualizes the graftspace between implant and bone, based on the pre-operative planning of the surgeon. The graft model serves as a visual reference for the surgeon in the OR.

    AI/ML Overview

    The provided text is a 510(k) summary for the Materialise Shoulder System™, which includes the Materialise Shoulder Guide and Models (hardware) and the SurgiCase Shoulder Planner (software). This submission is for an extension of compatibility with additional Lima's Implant components, not a new device requiring a full de novo performance study. Therefore, the information regarding acceptance criteria and performance studies is limited and focuses on showing equivalence to the predicate device.

    Here's an analysis based on the provided text, highlighting what is (and isn't) present:

    1. Table of Acceptance Criteria and Reported Device Performance:

    The document describes the performance data in a qualitative manner, emphasizing equivalence to the predicate and existing testing. It does not provide a quantitative table of specific acceptance criteria (e.g., in terms of accuracy metrics, sensitivity, specificity) and corresponding performance outcomes for the newly added functionalities. Instead, it relies on the established performance of the predicate and the assertion that the changes do not affect safety or effectiveness.

    Acceptance Criteria (Implied)Reported Device Performance
    Software Functionality (Planning, Visualization, Features)"The planning functionality, visualization options and planning features are the same for the glenoid planning of the subject device as for the predicate device."
    Software Technology (Codebase, V&V Methods)"The subject device has the same code base as the predicate device and uses the same methods for design and verification and validation as the predicate device."
    Safety and Effectiveness of Software Changes"The subject software technology differences have been demonstrated that they do not affect the safety or effectiveness, or that they do not raise any new issues regarding to the safety and effectiveness compared to the predicate device."
    Hardware Intended Use, Design, Functionality, Operating Principles, Materials, Performance"The subject hardware device is substantially equivalent in intended use, design, functionality, operating principles, materials and performance characteristics compared with the predicate device."
    Hardware Accuracy and Performance (General)"Testing verified that the accuracy and performance of the system is adequate to perform as intended." (Applicable to previous versions, carried over)
    Biocompatibility, Sterility, Cleaning, Debris, Dimensional Stability, Packaging"Previous testing for biocompatibility, sterility, cleaning, debris, dimensional stability and packaging are applicable to the subject device and demonstrate substantial equivalence with the predicate device."

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

    • Software Validation: The document states that "Software verification and validation were performed, and documentation was provided following the 'Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.'" However, it does not specify the sample size used for the test set (number of cases/patients) or the data provenance (e.g., country of origin, retrospective/prospective). The validation is described as "verification against defined requirements, and validation against user needs," but no details on the specific data used for this validation are provided in this summary.
    • Hardware Testing: For hardware, it mentions "simulated surgeries using rapid prototyped bone models and previous cadaver testing on previously cleared devices K153602 and K131559." Again, sample sizes (e.g., number of models or cadavers) are not provided. The data provenance is implied to be from previous testing of predicate/cleared devices, but no specific details are given.

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

    This information is not provided in the document. Given that the submission focuses on substantial equivalence for an expanded compatibility, explicit ground truth establishment by experts for specific new performance metrics is not detailed. The "approved glenoid pre-surgical plan" by a "qualified surgeon" for generating guides suggests expert involvement in the planning process, but not in a formal ground truth assessment for a test set.

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

    This information is not provided. As no formal multi-reader ground truth establishment is described for a test set, an adjudication method would not be applicable in the context of the information given.

    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:

    • No MRMC comparative effectiveness study is mentioned. The device is a surgical planning tool and patient-specific instrumentation, not an AI diagnostic aid for human readers in the traditional sense. Therefore, an MRMC study comparing human readers with and without AI assistance is not relevant to this device's stated purpose and is not included in the submission summary.

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

    • The software component, SurgiCase Shoulder Planner, is described as assisting in the positioning of shoulder components and allowing the surgeon to "visualize, measure, reconstruct, annotate and edit pre-surgical plan data." The output is a "pre-surgical plan data file." This indicates a human-in-the-loop process where the surgeon interacts with and approves the plan.
    • While software verification and validation were performed, the summary does not explicitly describe a "standalone" performance study of the algorithm only in isolation from human interaction for clinical decision-making. Its function is to facilitate human planning, not replace it.

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

    • For the software, the ground truth for validation is implied to be against "defined requirements" and "user needs," which likely translates to the accuracy of planned measurements or component placements compared to a reference standard (e.g., expert-defined ideal parameters, possibly based on anatomical landmarks from CT images). However, the specific type of ground truth (e.g., expert consensus on optimal placement on a gold standard model) is not explicitly stated as pathology or outcomes data.
    • For the hardware, "simulated surgeries using rapid prototyped bone models and previous cadaver testing" would involve assessing the accuracy of guide placement and the resulting pin positioning relative to the pre-surgical plan. The "ground truth" here would thus be defined by the pre-surgical plan itself and the anatomical accuracy of the physical model/cadaver.

    8. The sample size for the training set:

    • The document is a 510(k) summary for a substantial equivalence claim, primarily for extending compatibility. It describes software "design and verification and validation," implying a traditional software development lifecycle. It does not mention a training set in the context of machine learning or AI models, as this is not presented as an AI-driven device with a learning component.

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

    • As no training set for a machine learning model is mentioned, this information is not applicable/provided.

    AI/ML Overview

    The provided text is a 510(k) summary from the FDA for a medical device called the "Materialise Shoulder System™". While it describes the device, its intended use, and states that non-clinical performance data indicates substantial equivalence to a predicate device, it does not contain the specific details required to answer all parts of your request regarding acceptance criteria and a study proving device performance.

    Here's an analysis of what can be extracted and what is missing:

    What's Available:

    • Device Name: Materialise Shoulder System™, Materialise Shoulder Guide and Models, SurgiCase Shoulder Planner
    • Purpose of the "Study": The document focuses on demonstrating substantial equivalence to a predicate device (K193560), rather than a specific clinical study with defined acceptance criteria for novel claims. The performance data presented are primarily non-clinical tests to support this substantial equivalence.
    • Type of Ground Truth: For the "Hardware," it mentions "simulated surgeries using rapid prototyped bone models and previous cadaver testing." For the "Software," it mentions "Software verification and validation were performed and documentation was provided following the 'Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.'" This implies validation against defined requirements and user needs, but not necessarily a clinical ground truth like pathology or outcomes data.
    • Data Provenance (Implied): The company, Materialise N.V., is based in Belgium. The non-clinical tests mentioned would likely have been conducted by or for the manufacturer. The previous cadaver testing would likely have been retrospective or specifically for previous clearances.

    What's Missing (and why based on the document type):

    The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a legally marketed predicate device. For this type of submission, extensive clinical studies with new acceptance criteria, expert adjudication, MRMC studies, or large training datasets for AI (if applicable, though this device seems more rule-based/software-assisted planning) are often not required if substantial equivalence can be demonstrated through non-clinical means and comparison to established predicate devices.

    Therefore, the following information is not provided in the document:

    1. A table of acceptance criteria and the reported device performance: The document states that testing "verified that the accuracy and performance of the system is adequate to perform as intended" and that the subject device "is as safe, as effective, and performs as well as the predicate device," but it does
