The document describes the KLS Martin Oral-Max Implants - MR Conditional, a bundled submission of various osteosynthesis systems and screws intended for use in craniomaxillofacial surgery. The purpose of this submission is to support the conditional safety and labeling modification of these devices in the magnetic resonance (MR) environment.

Here's an analysis of the acceptance criteria and the study that proves the device meets them:

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

The acceptance criteria are implied by the non-clinical tests conducted to support MR Conditional safety, aligning with relevant ASTM standards and FDA guidance. The reported device performance is that the devices can be safely scanned under specified conditions.

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

The testing involved computational modeling and simulation (CM&S). The "test set" in this context refers to the simulated scenarios and device configurations.

• Sample Size for Test Set: "the entire portfolio of KLS Martin maxillofacial implants" was simulated. This implies that all devices grouped under "KLS Martin Oral-Max Implants - MR Conditional" were included in the simulations. The document also mentions "various in-vivo device positions and landmarks," "worst-case single and multiple devices," and simulations in "10 cm increments." This suggests a comprehensive set of simulated scenarios rather than a traditional physical sample size.
• Data Provenance: Not explicitly stated as "country of origin" or "retrospective/prospective" in the same way clinical data is. The data is generated through computational modeling and simulation using MED Institute's FDA-qualified Medical Device Development Tool (MDDT) and the Duke virtual human anatomy. This is a form of prospective simulation data.

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

Not applicable in the traditional sense for this type of non-clinical, simulation-based study. The "ground truth" for the RF-induced heating simulations is derived from the established physics and engineering principles embedded in the FDA-qualified MDDT and the Duke virtual human anatomy model. The expertise lies in the development and validation of these computational tools and the interpretation of the simulation results by experts in MR safety and medical device engineering at MED Institute and the submitting company. The document does not specify the number or qualifications of individual experts validating the computational model, but implies that the MDDT itself is "FDA-qualified," indicating a level of expert review and agreement on its methodology.

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

Not applicable. Adjudication methods like "2+1" or "3+1" are typically used for consensus building among human expert readers for clinical studies, especially when establishing ground truth from image interpretation. This study is based on physical property testing and computational simulations, not human interpretation of clinical data.

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

Not applicable. This is not a study involving human readers or AI-assisted diagnostic performance. It focuses on the physical safety of implants in an MR environment.

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

The RF-induced heating assessment involved "Computational modeling and simulation (CM&S) ... using MED Institute's FDA-qualified Medical Device Development Tool (MDDT) and in a clinically relevant position within the Duke virtual human anatomy." This is a standalone algorithm/model-based assessment without a human-in-the-loop for the performance evaluation itself. Human experts design the simulations, configure the models, and interpret the results, but the "performance" (temperature rise, SAR calculations) is computed by the algorithm.

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

For the non-clinical tests:

• Magnetically induced displacement force, torque, and image artifacts: The "ground truth" is based on the physical properties of the materials and device designs, measured or calculated according to established ASTM standards (F2052-21, F2213-17, F2119-07).
• RF-induced heating: The "ground truth" for the simulations is derived from the established electromagnetic physics and thermal dynamics principles implemented in the FDA-qualified Medical Device Development Tool (MDDT) and applied to the Duke virtual human anatomy model. The MDDT's qualification process by the FDA implicitly establishes the reliability of its results as a form of "ground truth" for simulation-based assessments.

8. The sample size for the training set

Not applicable. This is a non-clinical study for MR safety assessment, not a machine learning model requiring a training set in the typical sense. The "training" for the MDDT is its initial validation and qualification against known physical phenomena and experimental data, which is a separate process from this submission.

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

Not applicable, as there is no training set for a machine learning model in this context. The "ground truth" for qualifying the simulation tool (MDDT) would have been established through extensive validation against experimental measurements and recognized physical theories.

The tmCMF Solution is intended for use as a software system and image segmentation system for the transfer of imaging information from a medical scanner such as a CT-based system. The input data file is processed by the tmCMF Solution, and the result is an output data file that may then be provided as digital models or used as input to a manufacturing portion of the system that produces physical outputs, including anatomical models, surgical guides, dental splints, and implants for use in maxillofacial, midface, and mandibular surgery. Implants are intended for bone fixation and reconstruction. restoration of bone defects, and intended to provide continuity in regions where the bone is missing and/or to augment the bone by means of an onlay device in the maxillofacial skeleton, midface, mandible, and chin in adolescents (greater than 12 to 21 years of age) and adults. The tmCMF Solution is also intended as a preoperative software tool for simulating/ evaluating virtual surgical treatment options.

TechMah CMF (tmCMF) Solution is a family of personalized product solutions for Reconstructive, Orthognathic, Trauma, and Augmentation procedures in the mandible and midface (including orbital floor, medial and lateral orbital walls). The solution is comprised of Surgeon Review Tool (SRT) software and maxillofacial and mandibular surgical instruments (surgical guides, anatomical models, and dental splints) and implants. The surgical instruments and implants are patient-specific devices and are designed utilizing CT and dental scan patient image data.

Surgical guides are patient-specific devices or templates based on pre-operative software planning designed to fit a specific patient. These guides are used to assist a surgeon in transferring the pre-operative plan to the surgery by guiding the marking/drilling of bone for plate fixation screws and the position of the osteotomy marking/cutting slots. Guides can be used in conjunction with anatomical models to verify anatomical positioning and fit. Surgical guides can be used with either tmCMF Solution patient-specific implants or compatible off-the-shelf DePuy Synthes implants.

Anatomical models are patient-specific models that are based on pre-operative anatomy and surqical planning specific to a patient. These models are used to assist a surgeon in transferring the pre-operative plan to the surgery by representing pre-operative, intra-operative, and post-operative anatomical models as quidance. Anatomical models can be used to check quide fit and facilitate the pre-bending of a non-patient-specific off-the-shelf plate.

Dental splints are patient-specific devices or templates based on pre-operative software planning designed to fit a specific patient. These templates are used to assist a surgeon in transferring the pre-operative plan to the surgery by guiding the dental alignment of bone and teeth.

Implants are patient-specific devices that are based on pre-operative software planning designed to fit a specific patient. These implants are integral components for CMF (craniomaxillofacial) procedures, facilitating bone repositioning, fixation, reconstruction, and the restoration of bone defects. They are designed according to the pre-operative surgical plan to ensure continuity in regions where bone is absent and to provide structural integrity to the maxillofacial skeletal components, midface, mandible, and chin. This could include stabilizing fractured or intraoperatively cut bone, fixating harvested graft segments, or augmenting bone defects. Implants can be used in conjunction with surgical guides and anatomical models to assist with anatomical positioning and fit.

The Surgeon Review Tool (SRT) software is used by surgeons for the review of surgical plans, surgical instruments, and implant designs. The SRT software is accessed through a web interface.

METICULY Patient-specific titanium maxillofacial mesh implant is intended for bone fixation and reconstruction, restoration of bone defects and intended to provide continuity in regions where the bone is missing and/or to augment the bone by means of an onlay device in the maxillofacial skeleton and midface.

The METICUL Y Patient-specific titanium maxillofacial mesh implant is a device designed individually for each patient and intended for use in selective trauma of the maxillofacial skeleton, maxillofacial surgery, and reconstructive procedures. It is specifically designed with a focus on applications of non-bending related scenarios. The implant is made of titanium alloys produced via additive manufacturing (Laser Powder Bed Fusion) and is intended to be used with titanium screws. All additive manufacturing and other post-processing steps are only to take place under Meticuly manufacturing control. The device is not intended to substitute for bone reconstruction in clinical situations where bone is needed for support and stability of the maxillofacial skeleton under functional loading conditions. It is intended for adults only (at least 22 years of age). The surgeon approves the design of the mesh implant prior to fabrication of the implant device by the sponsor. The proposed FaciMesh models are intended to treat the maxillofacial region, while the OrbiMesh models treat the Orbital region. The device is not intended for reconstruction of the orbital roof defects or for any frontal bone defects, such as the supra-orbital ridge. Additionally, the FDA-cleared commercially available titanium screws that can be used with the subject devices include the TITANIUM MINIPLATE SYSTEM (K951690) and MICRO TITANIUM PLATE SYSTEM (K951688).

The METICULY Patient-specific titanium maxillofacial mesh implant underwent various performance tests to demonstrate its substantial equivalence to predicate devices.

1. Acceptance Criteria and Reported Device Performance:

The document broadly mentions compliance with various ASTM and ISO standards for material properties, manufacturing quality, biological evaluation, sterilization, and packaging. While specific quantitative acceptance criteria are not explicitly listed in a single table alongside reported values within the provided text, the conclusion states that "Verification and validation testing confirms that the product specifications have been met, demonstrating that the device will perform as intended. There were no unexpected results which indicate the suitable material used and manufacturing process compared to the standards for medical devices." This implies that the device met the requirements outlined in the referenced standards.

Here's a breakdown of the performance aspects and the reported methods/outcomes:

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

The document does not specify the sample sizes for the various performance tests conducted (e.g., number of powder samples, printed devices for fatigue testing, implants for biocompatibility).

The data provenance is also not explicitly stated beyond the tests being conducted by the manufacturer to support the 510(k) submission. It doesn't mention country of origin for data or if it was retrospective or prospective.

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

This information is not provided in the document. The studies described are primarily engineering and laboratory-based performance tests for the device itself (materials, manufacturing, sterility), not clinical studies requiring expert ground truth for interpretation of medical images or patient outcomes.

4. Adjudication Method for the Test Set:

This information is not applicable as the described tests are laboratory-based device performance evaluations, not clinical studies requiring expert adjudication of results.

5. Multi Reader Multi Case (MRMC) Comparative Effectiveness Study:

An MRMC comparative effectiveness study was not done or reported in this document. The submission focuses on the chemical, physical, and mechanical properties of the device and its manufacturing process, not on its diagnostic or treatment efficacy as interpreted by human readers.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study:

This information is not applicable. The device is a physical implant, not an algorithm or software that performs a diagnostic or treatment function on its own. While the design process involves digital input (CAD data from CT scans), the "performance" described is of the physical mesh implant, not a standalone algorithm.

7. Type of Ground Truth Used:

For the performance tests, the "ground truth" is largely established by recognized industry standards (ASTM, ISO, USP-NF). For instance:

• Material properties: Measured values compared against specified ranges in ASTM F3001-14.
• Biocompatibility: Results of biological tests (cytotoxicity, irritation, sensitization, etc.) are compared against established biological endpoints defined by ISO 10993 series and USP-NF.
• Sterilization: Achievement of a defined Sterility Assurance Level (SAL) and compliance with microbial limits as per ISO/ANSI/USP standards.
• Manufacturing accuracy: Comparison of the physical implant to the digital design and CT scan data inputs, with acceptable tolerances implied by "consistently matches."

No pathology, expert consensus on patient outcomes, or outcomes data is mentioned as ground truth for these device performance tests.

8. Sample Size for the Training Set:

This information is not applicable as the document describes a physical medical device, not an AI/ML algorithm that requires a training set. The device design process involves patient-specific CT data, but this is an input for individual device fabrication, not a training set in the context of AI/ML.

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

This information is not applicable for the same reasons as point 8.

No, an MRMC comparative effectiveness study was not done. The document states "Clinical testing was not required as a basis for substantial equivalence." The studies focused on technical performance and comparison to predicate and reference devices.

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

This concept is not directly applicable to the Stryker Facial iD System as described. The "system" involves the design and manufacturing of patient-specific implants. While there's likely software involved in generating the designs from CT scans (similar to the predicate KLS Martin IPS software), the document focuses on the implant's performance rather than the standalone performance of a diagnostic algorithm or AI for interpretation. The device itself is an implant, not an AI software intended for standalone diagnostic use.

7. The Type of Ground Truth Used

• Mechanical Bench Testing: The ground truth is established by the performance characteristics of the Reference Device (K221855), against which the Subject Device's mechanical stability was compared for "substantial equivalence."
• Biocompatibility Testing: The ground truth is established by the international standards (ISO 10993-1, DIN EN ISO 10993-5, DIN EN ISO 10993-12) for biocompatibility.
• Cleaning & Sterilization: The ground truth is established by international standards (DIN EN ISO 17665-1, ISO 17665-2, ISO 14937) for sterilization and sterility assurance levels.
• End-User Testing: The ground truth is the "intended performance" under specified use conditions.

8. The Sample Size for the Training Set

This information is not applicable. The Stryker Facial iD System is a patient-specific implant system, not an AI model that requires a "training set" in the context of machine learning. The design of each implant is based on individual patient CT data.

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

This information is not applicable for the reasons stated above (not an AI model with a training set). The patient-specific designs are generated from individual patient CT scans based on established engineering principles and medical design specifications, informed by the capabilities proven by the predicate and reference devices.

The MedCAD® AccuPlate® 3DTi Patient-Specific Plating System is intended for use in the stabilization, fixation, and reconstruction of the maxillofacial / midface and mandibular skeletal regions in adolescents (greater than 12 to 21 years of age) and adults.

The MedCAD AccuPlate® 3DTi Patient-Specific Plating System is a metal bone plate used in conjunction with commercially available, non-locking metal bone screws for the fixation to bone in orbital, midface / maxillofacial, and non-continuity mandibular operations. The design and dimensions of each plate within the envelope specification is based upon the patient's anatomical data (CT scan, CBCT scan, or MRI), and the intended anatomy to be fixated as determined from input provided by the surgeon. The subject device is not intended to be bent or modified in surgery. If for any reason the surgeon chooses not to use the subject device in surgery, they may use any of the commercially available plates to complete the surgery. The subject device is additively manufactured from Ti-6AL-4V Extra Low Interstitial (ELI) titanium alloy, provided non-sterile, must be sterilized prior to use, and is intended for single use only. Plates are fastened to bone using commercially available non-locking bone screws with diameters ranging from 1.5mm to 2.7mm and lengths ranging from 3.5mm to 22mm.

Here's a summary of the acceptance criteria and study information for the MedCAD® AccuPlate® 3DTi Patient-Specific Plating System, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The FDA clearance letter mentions the following non-clinical performance tests. The acceptance criteria are implied to be "equivalent" to identified reference devices.

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

The document does not explicitly state the sample sizes (number of devices or tests) for the non-clinical performance tests (bending, pushout, fit and form validation). It also does not specify the country of origin of the data or whether the studies were retrospective or prospective, as these are non-clinical (mechanical and material) performance tests rather than clinical studies with patient data.

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

This information is not explicitly provided in the document. For non-clinical performance tests, "ground truth" is typically established by engineering standards and validated testing procedures, not by human experts in the same way as clinical image interpretation. The "Fit and Form Validation" mentions alignment with an "approved surgical plan," which would involve surgical expertise in its creation, but the number and qualifications of individuals involved in approving these plans or assessing the fit are not detailed.

4. Adjudication Method for the Test Set

Not applicable for these types of non-clinical, objective performance tests. Adjudication methods like 2+1 or 3+1 are typically used for subjective clinical interpretations by multiple readers (e.g., radiologists) in diagnostic accuracy studies.

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 study was mentioned. The MedCAD® AccuPlate® 3DTi Patient-Specific Plating System is a patient-specific surgical implant, not an AI-assisted diagnostic tool.

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

This concept is not directly applicable. The device itself is an implant. However, the "patient specific design process" for creating the implant is an "algorithm only" type of process in that it uses patient anatomical data to generate the device design. The "Fit and Form Validation" likely assessed the output of this design process against the intended surgical plan. The document states that the design process "was shown to produce devices that aligned with the approved surgical plan," indicating successful standalone performance of the design software.

7. The Type of Ground Truth Used

• Biocompatibility: Established by adherence to ISO 10993 standards and FDA guidance.
• Sterilization Validation: Established by adherence to ISO 17665 standards and FDA guidance, with a specific SAL target.
• Static and Dynamic Bending: Established by ASTM F382 standard, with comparison to a reference device's known performance.
• Axial Screw Pushout: Established by ASTM F543 standard, with comparison to a reference device's known performance.
• Fit and Form Validation: Established by alignment with an "approved surgical plan." This likely involves a comparison of the 3D-printed plate geometry with the virtual surgical plan derived from patient imaging data, which can be considered "design ground truth."

8. The Sample Size for the Training Set

The document does not describe the development or training of an AI algorithm in the traditional sense, so there is no mention of a training set sample size. The "patient-specific design software" is mentioned as being the same as a reference device (K192282), implying it's a previously validated system rather than a newly trained AI model.

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

As no training set for an AI algorithm is described, this information is not applicable.

Dental
The self-tapping screws and low profile emergency screws are intended for use in the fixation of bones of the maxillofacial and midfacial skeleton affected by trauma or for reconstruction, and can be used in pediatric patients older than 29 days and up to two (2) years of age (infants). The self-tapping screws and low profile emergency screws are designed to be compatible with the components (plates, meshes) of the Delta Resorbable Fixation System K213777.

The subject devices, the Delta System self-tapping screw (STS) and low profile emergency screw (LPES), are intended for use in the fixation of bones of the maxillofacial and midfacial skeleton, affected by trauma or for reconstruction. The subject device can be used in pediatric patients older than 29 days and up to two (2) years of age (infants), but is not intended for use in the mandible and/or full load bearing procedures.

The scope of this submission covers the addition of the subject device screws to the previously cleared Delta System. Through this submission there is no change to the existing articles within the Delta System. The subject device screws are designed to be compatible with the existing components of the Delta System (plates, meshes), which have been previously cleared through K213777. Compared to the original Delta System, the subject STS and LPES have a limited patient population of pediatric patients older than 29 days and up to two (2) years of age (infants).

The document provided is a 510(k) summary for a medical device called the "Stryker Resorbable Fixation System". This summary outlines the device, its intended use, and comparative information to a predicate device to demonstrate substantial equivalence to a legally marketed device.

However, the provided text does not contain information about an AI/ML device or a study to prove that a device meets acceptance criteria related to AI/ML performance. The document focuses on regulatory approval for an orthopaedic fixation system, specifically resorbable screws, based on traditional engineering performance testing (e.g., mechanical tests, material properties) and comparison to a predicate device.

Therefore, I cannot provide the requested information regarding AI/ML acceptance criteria, study details, sample sizes, expert involvement, or MRMC studies, as these concepts are not applicable to the content of the provided document.

The document discusses "acceptance criteria" in the context of:

• Regulatory Acceptance: The FDA's determination of substantial equivalence.
• Performance Testing: Bench test "acceptance criteria" are implied by the "Passed" results for tests like Insertion, Shear, and Pull-out, and "Passed" for Inherent Viscosity. These are mechanical and material property tests, not AI/ML performance metrics.
• User Validation Testing: A validation study was done to confirm usability, comprehension of Instructions for Use, and that user needs are met, concluding a "passing result." This relates to human factors and usability, not AI/ML performance.

In summary, the provided text does not contain the information needed to answer the prompt's specific questions about AI/ML device acceptance criteria and proving device performance related to AI/ML.

CMRP:
The Customized Mandible Recon Plate is indicated for use in primary mandibular reconstruction with bone graft, temporary bridging until delayed secondary reconstruction, secondary mandibular reconstruction, and mandibular fracture fixation.

SMRP:
The Surgeon iD Mandible Recon Plate is indicated for use in primary mandibular reconstruction with bone araft, temporary bridging until delayed secondary reconstruction, secondary mandibular reconstruction, and mandibular fracture fixation.

The subject devices include the Stryker Customized Mandible Recon Plate (CMRP) and Stryker Surgeon iD Mandible Recon Plate (SMRP). Both CMRP and SMRP are intended to be used for rigid internal fixation of primary, secondary mandibular reconstructions, and fixation of mandibular fractures; and have an indication for use in primary mandibular reconstruction with bone graft, temporary bridging until delayed secondary reconstruction, secondary mandibular reconstruction, and mandibular fracture fixation. Subject devices have similar intended use and technical characteristics as the primary predicate device (K193136) and the reference device (K190696), and the additional language in indications for use statement is supported by the reference device (K014263).

The subject devices' plate(s) are designed and manufactured for one patient and/or surgeon specifically, and the customized patient-specific and surgeon-specific design of the plate(s) allows certain features to be configured to meet the individual needs of each patient and surgeon. The subject devices' plate has additional design configuration options (such as branches and flanges, and updated plate bar widths of 5.75-7.5mm) when compared to the primary predicate device. The subject devices' plate(s) are provided with the Design Proposal document, an Instruction for Use (IFU), and an optional Anatomical Model. Additionally, the subject device is compatible with a separately provided Surgical Guides accessory.

The provided text describes a medical device submission (K222650) for the Stryker Customized Mandible Recon Plate and Stryker Surgeon iD Mandible Recon Plate. It focuses on demonstrating substantial equivalence to predicate devices, rather than a study proving the device meets clinical acceptance criteria. Therefore, most of the requested information regarding acceptance criteria, study design, sample sizes, expert involvement, and ground truth cannot be extracted from this document, as it pertains to clinical performance which was explicitly stated as not required.

However, the document does mention "performance testing" related to mechanical strength and "End User Validation" that met pre-defined acceptance criteria.

Here's the information that can be extracted, and where details are missing:

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

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

• Test Set Sample Size: Not specified for mechanical strength testing (e.g., number of plates tested). Not specified for end-user 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 (e.g. radiologist with 10 years of experience)

• Number of Experts: For End User Validation, it refers to "skilled users" and "surgeons," but the specific number is not provided.
• Qualifications of Experts: It specifies "skilled users" and "surgeons" for the end-user validation, but further details on their specific qualifications or experience are not provided.

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

• Not applicable to the mechanical bench testing or the described end-user validation.

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, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This submission is for a physical medical device (bone plate), not an AI/software device.

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

• Not applicable. This is not an algorithm/AI device.

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

• Mechanical Strength Testing: The "ground truth" or reference for evaluating mechanical strength was established by "the corresponding worst case design" and the tests performed "according to the standards ASTM F382 and ASTM STP 731."
• End User Validation: The "ground truth" was whether the "user needs / design inputs were met." This was assessed by surgeons in a simulated use scenario.

8. The sample size for the training set

• Not applicable. This device is not an AI/machine learning model that requires a training set.

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

Ask a specific question about this device

The Tandry CMF System is a Maxillofacial plate and screw system intended for osteotomy, stabilization and rigid fixation of maxillofacial/midface fractures and reconstruction including infraorbital area and maxillofacial, and mandibular and maxillary correction surgery.

Each plate is indicated to be used in the following anatomic regions:

• · 1.2mm upper-face plates Orbital floor region, zygomatic region, and dento-alveolar region
• · 1.5mm mid-face plates Zygomatic region, orbital floor region, and maxilla
• · 2.0 mm mini plates Orthognathics midface/mandible
• · 2.0/2.3mm mandible plates Mandibular

The Tandry CMF Plate System consists of various sized plates and screws. The plates and screws are fabricated from pure titanium and Ti-6Al-4V. The plates are designed to distribute for respective anatomical and indicated areas, besides, they can be used with self-tapping, self-drilling, emergency self-tapping and locking screws.

This document is a 510(k) Premarket Notification from Microware Precision Co., Ltd. for their Tandry CMF Plate System. It describes the device, its intended use, and compares it to predicate devices to demonstrate substantial equivalence.

Based on the provided text, here's an analysis of the acceptance criteria and study information:

Key Takeaway: The submission explicitly states that clinical studies were NOT required to support substantial equivalence for this device. Therefore, information related to clinical performance, human reader studies, and specific AI acceptance criteria (which would typically be evaluated in such studies) is not present in this document. The "study" here refers to non-clinical tests.

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

The document does not present a formal table of acceptance criteria in the sense of a numerical performance target (e.g., sensitivity, specificity, accuracy) combined with reported device performance from a clinical study. This is because, as stated, clinical studies were not required.

Instead, the acceptance criteria are implicitly met by demonstrating substantial equivalence to predicate devices through non-clinical testing (biomechanical tests, biocompatibility, reprocessing, and sterilization).

Here's a breakdown of the non-clinical test results:

• The results support substantial equivalence to predicate devices. |
  | Biocompatibility | - Sample preparation per ISO 10993-12.
• Biological Safety Assessment guided by ISO 10993-1.
• Cytotoxicity testing per ISO 10993-5.
• The previous testing results for the predicate device (Tandry Locking Plate System K171904) are utilized, asserting the proposed device meets validation requirements. |
  | Reprocessing and Sterilization | - Previous testing results for the predicate device (Tandry Locking Plate System K171904) are utilized, as the material, manufacturing process, geometry, physico-chemical, body/fluid contact, and sterilization process are the same.
• Validated steam sterilization instructions to a sterility assurance level (SAL) of 10-6 using the biological indicator overkill method (in accordance with ANSI/AAMI/ISO 17665-1 and ANSI/AAMI/ISO 14937). |
  | Design Characteristics | - Dimensions, shape, and sizes are similar to predicate devices (as detailed in the comparative table on page 6). |
  | Material Composition | - Fabricated from pure titanium (ASTM F67) and Ti-6Al-4V (ASTM F136), which are standard materials used in predicate devices. |

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

This information is not applicable as no clinical test set or human data was used for a performance study. The "test set" for this submission consists of device samples evaluated in non-clinical lab settings (biomechanical and biocompatibility tests). No specific sample sizes for these lab tests are provided in the summary, other than "representative samples."

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 applicable as no clinical study with expert interpretation was conducted.

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

This information is not applicable as no clinical study with human readers requiring adjudication was conducted.

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 was done or required. The device is a traditional medical implant (plate and screw system), not an AI-powered diagnostic or assistive technology.

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

This information is not applicable as the device is not an algorithm or AI system.

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

For the non-clinical tests, the "ground truth" is defined by established engineering standards and biological safety guidelines (e.g., ASTM standards for biomechanics, ISO series for biocompatibility and sterilization). There is no clinical "ground truth" (like pathology or outcomes data) established or reported because no clinical study was performed.

8. The sample size for the training set

This information is not applicable as the device is not an AI/ML algorithm that requires a training set.

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

This information is not applicable as the device is not an AI/ML algorithm that requires a training set.

In summary, the document details a 510(k) submission for a traditional mechanical medical device, where substantial equivalence is demonstrated through non-clinical bench testing and comparison to predicate devices, rather than through clinical trials or AI performance evaluations.

Ask a specific question about this device

Craniomaxillofacial Implants: The Universal CMF System is a Craniomaxillofacial (CMF) plate and screw system intended for osteotomy, stabilization and rigid fixation of CMF fractures and reconstruction.

Mandible Implants: The Universal CMF System (mandible modules) is a mandibular plate and screw system intended for stabilization and rigid fixation of mandibular fractures and mandibular reconstruction.

The subject device (combination of Universal CMF System (K022185) and NewGen/Universal Mandibular System (K014263)) consists of multiple modules including fracture and reconstruction modules. The modules consist of straight, angled, hemi/full mandible bridging, curved, and pre-bent plates. The screws in the modules include 1.2-2.7mm self-tapping, self-drilling, and locking screws that vary from 3mm-42mm in length. The plates and screws are made of commercially pure titanium (ASTM F 67-95) and titanium alloy (ASTM F136-98).

It appears there's a misunderstanding of the provided FDA document. The document, K221855 for the "Universal CMF System," is a 510(k) premarket notification for a bone plate and screw system, which is a physical medical device used for fixing craniomaxillofacial fractures.

It is NOT an AI/ML-driven medical device. Therefore, the document does not contain information about:

• Acceptance criteria for an AI/ML algorithm's performance (e.g., sensitivity, specificity, AUC).
• A "study" proving device performance in the context of an AI/ML algorithm (e.g., clinical trials for AI diagnostic accuracy).
• Test set sample sizes, data provenance, expert ground truth establishment, adjudication methods, MRMC studies, standalone algorithm performance, or training set details.

The "performance data" section (VIII) refers to:

• Sterilization validation: Ensuring the device can be properly sterilized by the end-user.
• Performance bench testing: Mechanical tests to ensure the physical plates and screws meet engineering standards (e.g., biocompatibility, insertion/removal torque, failure strength). These are standard tests for physical implants, not AI algorithm performance metrics.
• Animal and Clinical Testing: Explicitly states "not required as a basis for substantial equivalence" for this physical device.

In summary, there is no AI/ML component described in this document, and therefore, it's impossible to extract the requested information about AI/ML acceptance criteria and performance studies from it.

The request asks for specific details relevant to the validation of an AI/ML device. Since this document pertains to a physical implantable device, those details simply do not exist within this filing.
