    Intended Use

    Patient Specific Implants are intended for the replacement of bony voids in the cranial and craniofacial skeleton (orbital rim, zygoma, and adjacent bone).

    Device Description

    The Patient Specific Implants (PSI) are preformed implantable devices used to reconstruct portions of a patient's skull. The implant is designed using CT data to produce a preformed/pre-shaped implant that will fit the anatomy of a specific patient and is manufactured from PEEK (polyetheretherketone). The PSIs are provided non-sterile and are surgically attached to the native bone using commercially available Synthes 1.3 mm – 2.0 mm screws.

    The manufacturing process is subtractive manufacturing (CNC milled) from models created and developed from patient specific CT Scan Data. The software used in this process is similar to the software used in the predicate device (K220357). This submission covers the use of software as an enabling technology that can be used as an option for the design of Patient Specific Implants. The device is designed to meet the needs of a specific patient upon request from a physician, and the basic design specifications must fall within the parameters defined in previous clearance for the system under K033868 / K053199. All designs must be approved by the physician prior to manufacture.

    Intended Use

    CustomizedBone Service (CustomizedBone) is intended to replace bony voids in the cranial and/or craniofacial skeleton (frontal bone including the brow ridge). This device is indicated for both adult and pediatric use (for children 7 years of age and above). CustomizedBone implants are suitable for reconstructing craniofacial defects resulting from:

    • trauma and vascular pathologies, either associated or non-associated to cranial decompression;
    • removal of tumours;
    • reabsorption of autologous bone;
    • rejection of other prosthetic materials;
    • congenital malformations.
    Device Description

    CustomizedBone Service patient specific implants for the reconstruction of cranial/craniofacial defects are made of porous biomimetic hydroxyapatite with a chemical composition and structure that resembles the mineral component of human bones. This biomaterial is highly porous with trabecular structure and is composed of pores with the following characteristics:

    • macro-pores,
    • interconnecting pores,
    • micro-pores.
      This material is biocompatible.
      The implants are designed and produced by Fin-Ceramica Faenza according to the surgeon's specifications and based on the patient's CT scan data, obtained through a standardized protocol. During the pre-operative planning phase, the final implant design. All the implants are accompanied by the patient's identification code.
    AI/ML Overview

    The provided text describes a 510(k) premarket notification for a medical device called "CustomizedBone Service." It focuses on demonstrating substantial equivalence to a legally marketed predicate device. The information provided is primarily related to the device's design, material, intended use, and a minor change in fixation method.

    Crucially, the document does NOT contain information about acceptance criteria or a study proving the device meets those criteria in the context of typical AI/ML medical device performance studies. The document describes a traditional medical device submission, not an AI/ML-driven device.

    Therefore, I cannot extract the information required to populate the fields related to acceptance criteria, device performance, sample sizes, expert ground truth establishment, adjudication methods, MRMC studies, standalone performance, training data, or ground truth for training data as these concepts are not discussed in the provided text.

    The "Non-Clinical and/or Clinical Tests Summary & Conclusions" section mentions tests for "Stability verification of CustomizedBone Service stabilized with Cranial LOOP (L)" and "Usability of an alternative method of fixation." However, these are mechanical/usability tests for a physical implant, not performance metrics for an AI/ML algorithm.

    In summary, the provided content is insufficient to answer the prompt because it describes a hardware medical device (cranioplasty plate) and not an AI/ML-driven device requiring the specified performance evaluations.

    Intended Use

    The Longeviti ClearFit OTS cranial implants are manufactured to correct and/or restore bony voids and/or defects of the cranium.

    Device Description

    The Longeviti ClearFit OTS (off-the shelf) cranial implants are ultrasound penetrable fixed size prosthetic cranioplasty plates intended to correct and/or restore bony voids and/or defects of the cranium. The implants are manufactured from polymethyl methacrylate (PMMA) materials. The devices are provided sterile and can be fixated to cranial bone using commercially available fasteners.

    AI/ML Overview

    The provided text is a 510(k) summary for the Longeviti ClearFit OTS Cranial Implant. It describes the device, its intended use, and its classification. However, it does not contain information about acceptance criteria for a study demonstrating device performance, nor details of a study that proves the device meets such criteria. Specifically, it lacks:

    • A table of acceptance criteria and reported device performance.
    • Details on sample size, data provenance, number and qualifications of experts, or adjudication methods for a test set.
    • Information on MRMC studies, standalone algorithm performance, or the type of ground truth used.
    • Information regarding the training set's size or how its ground truth was established.

    The document primarily focuses on the regulatory aspects of the device, establishing substantial equivalence to a predicate device, and outlining general controls and FDA regulations. It mentions that there are "no technological differences to the material (PMMA) and no differences to the materials of manufacturing. There are no differences to the packaging or sterilization process" compared to its predicate device (Longeviti ClearFit OTS Cranial Implant, K212058). This suggests that the substantial equivalence determination is based on the similarity of the device to previously cleared devices, rather than new performance data from a specific study demonstrating new acceptance criteria.

    Therefore, I cannot fulfill the request to describe acceptance criteria and a study proving their fulfillment based on the provided text. The text does not contain that information.

    AI/ML Overview

    I am sorry, but the provided text does not contain the information required to answer your request. The document is an FDA 510(k) premarket notification letter and a 510(k) summary for a medical device (PEEK Patient Specific Cranial/Craniofacial Implant).

    It details:

    • The device's identification and intended use
    • Comparison to a predicate device
    • Non-clinical testing for biocompatibility and performance (compression, fitting, fixation)
    • A statement that no clinical tests were performed.

    Therefore, there is no mention of acceptance criteria based on device performance in a clinical study, sample sizes for test sets, data provenance, expert ground truth establishment, adjudication methods, MRMC studies, standalone algorithm performance, or ground truth for training sets. This information would typically be found in a clinical study report, which is not present here.

    Intended Use

    The MedCAD® AccuShape® Titanium Patient-Specific Cranial Implant is designed individually for each patient and intended to correct defects / replace bony voids in the cranial skeleton.

    Device Description

    The MedCAD® AccuShape® Titanium Patient-Specific Cranial Implant is a preformed non-alterable cranioplasty plate that cannot be altered or reshaped at the time of surgery and is designed to be implanted in a patient to repair a skull defect.
    The subject device is composed of commercially pure (CP) Grade 2 titanium per ASTM F67. The manufacturing process is subtractive manufacturing (CNC milled) from models created and developed from patient specific CT Scan Data. The software used in this process is identical to the software used in the predicate device (K110684). The device is designed to have, as requested by the physician, drainage holes over the defect void area, fixation holes over an onlay area, and retractions and other features that fall within the approved design envelope. All designs must be approved by the physician prior to manufacture.

    AI/ML Overview

    The provided document describes the MedCAD AccuShape Titanium Patient-Specific Cranial Implant and its substantial equivalence to a predicate device (MedCAD AccuShape PEEK Patient Specific Cranial Implant) based on non-clinical performance testing.

    It is important to note that this document does not describe an AI/ML-driven device or study parameters typical for such devices (e.g., ground truth establishment for a training set, human reader studies, or expert consensus on clinical data). The device described is a physical cranial implant, and the study referenced in the document is a series of non-clinical performance tests designed to assess the physical and mechanical properties of the implant, not its diagnostic or predictive accuracy in an AI context.

    Therefore, many of the requested bullet points, particularly those pertaining to AI/ML device evaluation (like sample size for test/training sets of data, number of experts for ground truth, MRMC studies, standalone performance), are not applicable to the information provided in this document.

    However, I can extract information relevant to the device's acceptance criteria and the non-clinical performance testing performed for this physical device.


    Here's an interpretation of the "acceptance criteria" and "study" as presented for a physical medical device, rather than an AI/ML diagnostic:

    Device: MedCAD AccuShape Titanium Patient-Specific Cranial Implant (K220357)

    Purpose of the "Study" (Non-Clinical Performance Testing): To demonstrate the substantial equivalence of the MedCAD AccuShape Titanium Patient-Specific Cranial Implant to its predicate device (MedCAD AccuShape PEEK Patient Specific Cranial Implant, K110684) by evaluating its physical and mechanical properties.


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

    TestAcceptance Criteria (Inferred from "Results" and "Test Method Summary")Reported Device Performance (Results)
    MR Compatibility TestingTo characterize the device's behavior in a Magnetic Resonance Environment per ASTM F2503-20. The acceptance is a clear designation regarding MR compatibility (e.g., safe, unsafe, conditional).The subject device was characterized to be MR Unsafe. This designation is noted in the labeling.
    Screw Fixation TestingVerification that fixation retention of the implant at the point of fixation of the screw is at least as strong as the axial pullout forces measured in prior testing of FDA-cleared neuro screws in an established cortical bone model.PASS: The fixation retention of the implant at the point of fixation of the screw is at least as strong as the axial pullout forces measured in prior testing of FDA-cleared neuro screws in an established cortical bone model.
    Evaluation of Fit TestingManufactured implant, based on worst-case CT data (1.25mm scan thickness) from historical cases, must optically align with the 3D model and must fit over the corresponding defect in a representative anatomical model when evaluated by qualified inspectors. Predetermined acceptance criteria must be met.PASS: All samples met the predetermined acceptance criteria.
    Comparative StrengthThe subject device must demonstrate substantial equivalence in strength to the predicate device (K110684 AccuShape PEEK) when subjected to a load/displacement test until failure, ensuring similar mechanical performance for the same defect geometry and fixation.PASS: The subject device was substantially equivalent to the predicate device. (Implies that the load/displacement curves and failure points demonstrated comparable mechanical performance to the predicate when tested under identical conditions).

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

    • Sample Size for Test Set:
      • Evaluation of Fit Testing: "3 large defect predicate historical cases (K110684)" were used to generate "worst case CT data". The number of manufactured implants tested is implied to be at least 3 (one for each case). The phrase "All samples" in the result suggests a specific number of manufactured implants were produced and tested, but the exact number isn't quantified beyond the 3 cases used for input data.
      • Comparative Strength: "Identical subject and predicate devices" were used, implying at least one (and likely more for statistical significance, though not stated) of each type (titanium and PEEK) for comparative testing.
      • Screw Fixation: Not explicitly stated, but implies multiple tests to determine "at least as strong as" criteria.
      • MR Compatibility: At least one device (or representative sample) would be tested.
    • Data Provenance: The "worst case CT data" for the Evaluation of Fit testing came from "3 large defect predicate historical cases (K110684)". This suggests a retrospective use of previously acquired clinical data (CT scans) from actual patients. The country of origin is not specified but is implicitly USA, given this is an FDA submission.

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

    • This concept is not directly applicable in the context of this device's non-clinical testing. The "ground truth" (or reference standard) is based on engineering specifications, material properties, and established test methodologies (e.g., ASTM standards, previous FDA-cleared device performance).
    • For the "Evaluation of Fit Testing," "qualified inspectors" performed the evaluation. Their qualifications (e.g., years of experience, specific certifications) are not detailed beyond "qualified".

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

    • Not applicable. Adjudication methods are typically used in clinical studies involving multiple human readers interpreting medical images, where discrepancies need to be resolved. This document describes physical, non-clinical tests.

    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 physical implant, not an AI/ML diagnostic tool, and no human reader study was performed.

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

    • Not applicable. This is not an AI algorithm. The manufacturing software is mentioned (same as predicate device), but its performance in terms of design output is assessed through the physical device tests (e.g., Evaluation of Fit), not as a standalone AI model.

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

    • The "ground truth" for these tests is based on:
      • Engineering Specifications/Standards: e.g., ASTM F2503-20 for MR compatibility.
      • Predicate Device Performance: For comparative strength, the performance of the legally marketed predicate device (K110684 PEEK implant) served as the benchmark.
      • Established Biomechanical Principles: For screw fixation, comparison to "axial pullout forces measured in prior testing of FDA-cleared neuro screws in an established cortical bone model" serves as the reference.
      • 3D Digital Models/Physical Prototypes: For "Evaluation of Fit," the 3D digital model of the implant and representative anatomical models served as the reference for fit.

    8. The sample size for the training set

    • Not applicable. This device is not an AI/ML system that requires a "training set" of data in the machine learning sense. The manufacturing process uses patient-specific CT scan data as input for design, but this is not a training set for an AI model.

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

    • Not applicable, as there is no AI/ML training set in this context.

    Intended Use

    Meticuly patient-specific tianium mesh implant is a device that is designed individually for each patient. This device is intended for use in selective trauma of the craniofacial skeleton (e.g., frontal bone, temporal bone, occipital bone, parietal bone, sphenoid bone, supraorbital process, vomer), cranial and craniofacial surgery, and reconstructive procedures.

    Device Description

    Meticuly's Patient-specific Titanium Mesh Implant is a device designed individually to replace each patient's bony voids in the cranial and/or craniofacial skeleton comprises of frontal bone, temporal bone, occipital bone, parietal bone, sphenoid bone, supraorbital process, vomer. This patient-specific device is intended to be used with titanium screws. The subject device has been validated and tested with titanium screws with the diameter of 1.4 mm - 1.8 mm (K141452 : Jeil Medical's LeForte Neuro system screws). The implant is made of titanium alloys produced via additive manufacturing (Laser Powder Bed Fusion). The surgeon approves the design of the mesh implant prior to fabrication of the implant device.

    AI/ML Overview

    The provided text describes the Meticuly Patient-Specific Titanium Mesh Implant and its substantial equivalence determination by the FDA. However, it does not contain the specific information requested regarding an AI/ML powered device, specifically:

    • It does not describe acceptance criteria or reported device performance in terms of metrics like sensitivity, specificity, accuracy, or F1-score, which are typical for AI/ML devices.
    • It does not specify sample sizes for test or training sets in terms of patient numbers or image counts, nor data provenance (country of origin, retrospective/prospective).
    • It does not mention the number or qualifications of experts used for ground truth, any adjudication methods, or MRMC comparative effectiveness studies.
    • It does not refer to standalone performance for an algorithm or the type of ground truth (e.g., pathology, outcomes data).

    Instead, the document details the performance testing for a physical medical device (a patient-specific titanium mesh implant). The performance tests focus on material properties, manufacturing quality, biocompatibility, sterilization, packaging, and mechanical properties. The "comparative device modeling with Finite Element Analysis (FEA)", "comparative mechanical testing with modified compression test", and "comparative roughness testing" are all hardware-related validation activities, not AI/ML algorithm validation.

    Therefore, I cannot fulfill the request to provide the acceptance criteria and study details for an AI-powered device based on the provided text, as the text describes a physical implant and its regulatory submission, not an AI/ML device.

    The Longeviti ClearFit™ OTS Cranial Implants are manufactured to correct and/or restore bony voids and/or defects of the cranium.

    Device Description

    The Longeviti ClearFit™ OTS (off-the shelf) cranial implants are fixed size prosthetic cranioplasty plates intended to correct and/or restore bony voids and/or defects of the cranium. The implants are manufactured from polymethyl methacrylate materials. The devices are provided sterile and can be fixated to cranial bone using commercially available fasteners.

    AI/ML Overview

    The provided text is a 510(k) summary for the Longeviti ClearFit OTS Cranial Implants. It focuses on demonstrating substantial equivalence to a predicate device, not on proving that a specific new device (such as an AI/ML powered device) meets acceptance criteria for classification tasks (e.g., detecting disease, segmenting organs).

    Therefore, the document does not contain the information needed to answer questions 1-9 in the requested format, as those questions typically apply to studies evaluating the performance of AI/ML algorithms, especially in diagnostic or clinical decision support contexts.

    The document discusses:

    • Device Description: Off-the-shelf polymethyl methacrylate (PMMA) cranial implants.
    • Intended Use: Correct and/or restore bony voids and/or defects of the cranium.
    • Comparison to Predicate: The key difference highlighted is that the subject device is a fixed-size implant, while the predicate is a patient-specific implant. However, the document emphasizes that they use the same materials and manufacturing processes.
    • Performance Testing: References several ASTM standards for tensile, flexural, and impact properties of plastics, stating that these tests were "passed" and are applicable due to similar materials and manufacturing.

    It does not describe:

    • Acceptance criteria for an AI/ML algorithm's performance (e.g., sensitivity, specificity, AUC).
    • A "study" in the sense of a clinical trial or algorithm performance evaluation using a test set of data with ground truth.
    • Sample sizes for AI training or test sets.
    • Expert involvement for ground truth establishment or MRMC studies.
    • Any AI/ML components.

    Therefore, it is impossible to populate the requested table and answer the study-related questions based on the provided text, as this document pertains to a physical medical device (cranial implant) and not an AI/ML powered device.

    The Longeviti ClearFit Implant is patient specific, implantable prosthetic cranioplasty plates intended to correct and/or restore bony voids and/or defects of the cranium. The implant is manufactured from polymethyl methacrylate materials and are designed using the patient's CT scan data. The devices are provided sterile and can be fixated to cranial bone using commercially available fasteners. An identical backup implant may be supplied as a courtesy to the surgeon, according to custom, but is not required. The typical maximum single plate size does not exceed a total surface area of 411 cm2 and should have a nominal thickness of 4mm, not to exceed 5mm, to ensure physical integrity. Perfusion holes (also known as drainage holes) are available upon surgeon request at the time of ordering. Perfusion holes are 2mm in diameter and spaced at least 10mm apart.

    AI/ML Overview

    I am sorry, but the provided text does not contain the information required to answer your request regarding the acceptance criteria and study proving device performance for an AI/CADe device. The document is a 510(k) premarket notification letter and summary for a cranial implant (Longeviti ClearFit Cranial Implant), which is a physical medical device, not an AI or CADe product.

    Therefore, I cannot provide:

    1. A table of acceptance criteria and reported device performance (for an AI/CADe).
    2. Sample sizes or data provenance for a test set.
    3. Number of experts or their qualifications for establishing ground truth.
    4. Adjudication method for a test set.
    5. Information about MRMC comparative effectiveness studies or effect sizes for human readers.
    6. Stand-alone performance data for an algorithm.
    7. Type of ground truth used (e.g., pathology, outcomes data).
    8. Sample size for the training set.
    9. How ground truth for the training set was established.

    The document explicitly states: "No new performance testing was required to determine substantial equivalence because the manufacturing and materials are identical to those described in K191210. The only additional testing for this submission was the addition of the acoustic property testing to support the labeling change." This indicates that the device's performance was not evaluated through the types of studies typically conducted for AI/CADe systems.
