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.

Ask a specific question about this device

MCI - CMF System is intended for use in selective trauma of the midface, maxillofacial surgery, reconstructive procedures, and selective orthognathic surgery of the maxilla, mandible and chin.

The bone plates are made from commercially pure titanium (ASTM F67) and the bone screws are manufactured from titanium alloy - Ti-6AI-4V (ASTM F136) and are available in different sizes and shapes, according the site of the implantation and the extension of the fracture. The surface of plates and screws are colored-anodized. MCI - CMF System implant devices are for single use. The devices are provided non-sterile and must be properly cleaned, disinfected and sterilized before use, according the recommendations provided in the Instructions for Use.

I am sorry, but the provided text describes a 510(k) premarket notification for a medical device called the "MCI - CMF System," which consists of bone plates and screws. This document focuses on demonstrating substantial equivalence to existing predicate devices, primarily through comparison of design, materials, indications for use, and a limited set of mechanical and biocompatibility tests.

There is no mention of an AI/algorithm-driven device, nor are there any acceptance criteria or studies related to AI model performance, accuracy, or human-in-the-loop studies involving expert readers.

Therefore, I cannot fulfill your request to describe acceptance criteria and a study that proves a device meets acceptance criteria in the context of an AI/algorithm. The provided text simply does not contain this information.

To elaborate on why I cannot answer based on the provided text:

• No AI/Algorithm: The "MCI - CMF System" is a physical medical implant (bone plates and screws). It is not software, an algorithm, or an AI system.
• No Diagnostic Claims: The device is for "selective trauma of the midface, maxillofacial surgery, reconstructive procedures, and selective orthognathic surgery of the maxilla, mandible and chin." These are surgical indications, not diagnostic. There's no AI that would be "reading" images or assisting in diagnosis.
• No Acceptance Criteria for AI Performance: Since it's a physical implant, the "performance" data refers to mechanical testing (e.g., bending fatigue of plates, pullout strength of screws) and biocompatibility, not AI metrics like sensitivity, specificity, AUC, or reader studies.
• No Test Set Details: There's no test set of patient data, as there's no AI to evaluate on such data.
• No Expert Ground Truth or Adjudication: These concepts are relevant for evaluating AI in diagnostic imaging or clinical decision support, which is not the function of this device.
• No MRMC or Standalone AI Study: These are types of studies specifically for AI performance evaluation.
• No Training Set Information: Again, training sets are for machine learning models, which are not described in this document.

The 510(k) summary concludes that the device is substantially equivalent based on engineering principles, material science, and the stated indications for use, compared to predicate devices already on the market.

The KLS Martin Individual Patient Solutions (IPS) Planning System 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 IPS Planning System and the result is an output data file that may then be provided as digital models or used as input to a rapid prototyping portion of the system that produces physical outputs including anatomical models, guides, splints, and case reports for use in maxillofacial surgery. The IPS Planning System is also intended as a pre-operative software tool for simulating / evaluating surgical treatment options.

The KLS Martin Individual Patient Solutions (IPS) Planning System is a collection of software and associated additive manufacturing (rapid prototyping) equipment intended to provide a variety of outputs to support reconstructive and orthognathic surgeries. The system uses electronic medical images of the patients' anatomy (CT data) with input from the physician, to manipulate original patient images for planning and executing surgery. The system processes the medical images and produces a variety of patient specific physical and/or digital output devices which include anatomical models, guides, splints and case reports.

The provided text describes the KLS Martin Individual Patient Solutions (IPS) Planning System and its regulatory clearance (K182789) by the FDA. However, it does not contain information about a study proving the device meets specific acceptance criteria in the context of an AI/algorithm's performance.

Instead, the document is a 510(k) summary demonstrating substantial equivalence to a predicate device (K181241), primarily to expand the patient population to include pediatric subgroups. The core of the device is a planning system involving commercial off-the-shelf (COTS) software and additive manufacturing for physical outputs, with human-in-the-loop interaction from trained employees/engineers and physicians.

Therefore, most of the requested information regarding AI acceptance criteria, performance metrics, sample sizes, ground truth establishment, expert adjudication, and MRMC studies is not present in the provided document. The device, as described, is not an AI algorithm in the sense that it performs automated diagnostic or treatment recommendations independently based on image analysis with defined metrics. It's a system to assist human planning processes.

Here's an analysis based on the information available in the document, and a clear indication of what is not available.

Acceptance Criteria and Device Performance (as far as applicable from the document)

The document focuses on demonstrating substantial equivalence, not on acceptance criteria for a freestanding AI algorithm's performance. The "performance" described is primarily related to material properties, biocompatibility, and sterilization, and the functioning of the software as a tool for human planning.

Information NOT Available in the Document (as it pertains to an AI/Algorithm performance study):

1. Sample size used for the test set and data provenance:
   This information is not provided. The study performed was primarily non-clinical (material testing, biocompatibility, sterilization) and a risk assessment for pediatric use, not a clinical trial evaluating algorithm performance on a test set of patient data.

2. Number of experts used to establish the ground truth for the test set and their qualifications:
   Not applicable, as no dedicated test set for evaluating AI/algorithm performance against a ground truth is described. The system relies on physician input and interaction with trained employees/engineers for planning, not on an autonomous algorithmic output that requires expert adjudication for ground truth.

3. Adjudication method for the test set:
   Not applicable for the same reasons as above.

4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:
   No, an MRMC comparative effectiveness study was not done. The document explicitly states: "Clinical testing was not necessary for the determination of substantial equivalence." (p.11, p.14). The device is a planning system with human-in-the-loop, not an AI intended to improve human readers' performance directly.

5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
   No, a standalone algorithm performance study was not described. The device is presented as a "software system and image segmentation system" where "trained employees/engineers... manipulate data and work with the physician to create the virtual planning session." (p.4, p.13) The core function described is human-assisted planning and production of physical models, not an autonomous algorithmic output.

6. The type of ground truth used:
   Ground truth in the context of an AI algorithm's diagnostic or predictive performance is not relevant here, as no such AI is described. The "ground truth" for the device's function would relate to the accuracy of the generated physical models and plans relative to the patient's anatomy and surgical intent, which is managed through human interaction and validation within the system's intended use.

7. The sample size for the training set:
   Not applicable. The document refers to "commercially off-the-shelf (COTS) software applications" (p.4, p.13) which implies existing, validated software tools are being used, not a newly developed AI model requiring a separate training set.

8. How the ground truth for the training set was established:
   Not applicable, as no new training set for an AI model is described.

The system processes the medical images and produces a variety of patient specific physical and/or digital output devices which include anatomical models, guides, splints and case reports.

Here's an analysis of the acceptance criteria and study information based on the provided text, focusing on what is present and what is not:

The document (K181241 510(k) Summary) describes the KLS Martin Individual Patient Solutions (IPS) Planning System, which is a software system for image segmentation and pre-operative planning, and also provides physical outputs like anatomical models, guides, and splints for maxillofacial surgery. The submission focuses on demonstrating substantial equivalence to a predicate device (VSP System K120956) and uses several reference devices.

Acceptance Criteria and Study Information:

Based on the provided text, the device itself is a planning system that ultimately produces physical outputs. The "performance" being evaluated relates to the characteristics of these physical outputs (tensile strength, biocompatibility, sterility, pyrogenicity) and the software's functionality. There isn't a direct "device performance" metric in the traditional sense of an AI diagnostic device's sensitivity, specificity, or accuracy against a clinical outcome.

1. Table of Acceptance Criteria and Reported Device Performance

Given the nature of the device (planning system with physical outputs, not a diagnostic AI), the performance metrics are primarily related to safety and manufacturing quality.

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

• Test Set Sample Size: The document does not specify a "test set" in the context of a dataset for evaluating AI performance (e.g., medical images for segmentation accuracy). Instead, "testing" refers to non-clinical performance evaluations of the physical outputs and software.
  • For Tensile & Bending, Biocompatibility, Sterilization, and Pyrogenicity, the sample sizes are not explicitly mentioned, but the tests were performed on "the subject polyamide guides" and "titanium" components. The provenance is internal testing performed by the manufacturer, or results leveraged from previous KLS Martin device submissions.
  • For Software V&V, no specific numerical "test set" of software inputs is given, but testing was performed on "each individual software application."
• Data Provenance: The data provenance for non-clinical testing is internal to the manufacturer or relied upon previous regulatory submissions for similar materials/processes. It is not patient or country-specific data as would be for clinical studies. The data used by the IPS Planning System itself (CT data) would be patient data, but the evaluation here is of the system's outputs, not its interpretation of patient data in a diagnostic manner. The document states the system "transfers imaging information from a medical scanner such as a CT based system."

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

• This question is not applicable in the context of this 510(k) submission. The "ground truth" for the non-clinical tests (tensile strength, biocompatibility, etc.) is established by standard scientific and engineering methodologies, not by expert medical review of images.
• For the "Software Verification and Validation," the "ground truth" for software functionality is defined by the established software requirements and specifications, validated by internal quality and user acceptance testing, not by external experts in the medical domain. The document mentions "input from the physician" for manipulation of original patient images, suggesting physicians set the clinical goals for the plan, but the validation of the system's performance is not described as involving experts establishing a "ground truth" concerning image interpretation.

4. Adjudication method for the test set

• Not applicable. There is no adjudication method described as would be used for clinical interpretation or diagnostic performance evaluation by multiple experts. The non-clinical tests follow established standards and protocols.

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 device is a planning system for maxillofacial surgery, not a diagnostic AI that assists human readers in image interpretation or diagnosis. It aids in surgical planning and creates physical outputs. The submission explicitly states: "Clinical testing was not necessary for the determination of substantial equivalence."

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

• Given the device's function, it is inherently a "human-in-the-loop" system. The description states: "The system uses electronic medical images of the patients' anatomy (CT data) with input from the physician, to manipulate original patient images for planning and executing surgery." And, "The physician provides input for model manipulation and interactive feedback through viewing of digital models...that are modified by the trained employee/engineer during the planning session."
• Therefore, performance of the algorithm without human intervention is not the intended use or focus of this submission. The "software verification and validation" (Section 11) is the closest thing to an "algorithm-only" evaluation, but it's about software functionality, not standalone image interpretation performance.

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

• For the non-clinical performance tests of the physical outputs (Tensile & Bending, Biocompatibility, Sterilization, Pyrogenicity), the "ground truth" is defined by established engineering and scientific standards (e.g., ISO 10993-1, ISO 17665-1:2006, AAMI ANSI ST72, and internal specifications).
• For Software Verification & Validation, the "ground truth" is adherence to predefined software requirements and specifications (functional and non-functional, related to image transfer, manipulation, and output file generation). It is not based on medical "ground truth" like pathology or clinical outcomes.

8. The sample size for the training set

• This question is not applicable. The KLS Martin IPS Planning System is described as using "validated commercially off-the-shelf (COTS) software applications" for image manipulation. There is no mention of a "training set" in the context of machine learning or AI model development within this summary. It appears to be a rule-based or conventional algorithmic system rather than a deep learning/machine learning model that would require a distinct training set.

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

• This question is not applicable, as no training set for machine learning was mentioned or identified in the document (see point 8).

These patient-specific devices are fixated with previously cleared KLS Martin screws.

Here's a summary of the acceptance criteria and study information for the KLS Martin Individual Patient Solutions device, based on the provided document:

This document focuses on the mechanical and material performance of the device rather than the performance of an AI algorithm in a diagnostic or clinical decision support context. Therefore, many of the typical AI/ML study questions (like effect size of human readers with/without AI, standalone algorithm performance, number of experts for ground truth, etc.) are not applicable here.

1. Table of Acceptance Criteria and Reported Device Performance

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

• Test Set Sample Size: Not explicitly stated in terms of number of physical devices or specific data points for performance testing. The document refers to "the subject plates" for mechanical testing, implying a representative sample was tested.
• Data Provenance: The studies are non-clinical bench tests and conducted by the manufacturer, KLS Martin LP. The data originates from these laboratory tests, not from patient data or clinical settings. It is a retrospective analysis of device performance against established standards.

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

• This device is a medical implant, not a diagnostic AI device. There is no concept of "ground truth" established by human experts in the context of diagnostic interpretation for its performance testing. The "ground truth" for its performance is derived from established engineering and materials science standards (ASTM, ISO, etc.).

4. Adjudication Method for the Test Set

• Not applicable. The performance tests are objective measurements against engineering standards, not subjective interpretations requiring adjudication.

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 a medical implant, not an AI diagnostic or decision support tool. No human reader studies with or without AI assistance were conducted or are relevant.

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

• Not applicable. This is a medical implant. The "algorithm" in this context refers to the manufacturing process driven by patient CT data and physician input for design, not an AI algorithm for diagnosis or interpretation. The device itself is "standalone" in that it performs its mechanical function once implanted, but its pre-market testing does not involve "algorithm-only performance" as would be understood for an AI/ML product.

7. The Type of Ground Truth Used

• Engineering Standards and Specifications: The "ground truth" for this device's performance is derived from compliance with established international standards for medical devices and materials, specifically:
  • ASTM F382 (Standard Specification for Metallic Bone Plates) for mechanical performance.
  • ISO 17665-1:2006 (Sterilization of health care products — Moist heat — Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices) for sterilization.
  • ISO 10993 (Biological evaluation of medical devices) for biocompatibility.
• For the patient-specific design process, the "ground truth" for dimensional fit is a virtual fitting against a 3D model of the patient's anatomy derived from a CT scan.

8. The Sample Size for the Training Set

• Although the device design is patient-specific and involves a "virtual planning" phase, this is not an AI/ML product that learns from a "training set" in the conventional sense. Each device is unique to a patient based on their CT scan. The "training" for the manufacturing process (both traditional and additive) happens through engineering validation and quality control procedures, not through a data-driven training set for an algorithm.

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

• Not applicable, as there is no traditional "training set" for an AI/ML algorithm. The "ground truth" for the device's manufacturing and material properties is established through adherence to design specifications, material standards (ASTM F67, ASTM F136), and manufacturing quality control processes. The patient's CT scan provides the anatomical data for each individual device's design.

Internal Distraction - Sterile includes devices intended as bone stabilizers and lengthening (and or transport) devices for correction of congenital deficiencies or post traumatic defects of the cranial bones that require gradual distraction.

Internal Distraction - Sterile consists of sterile internal distraction devices intended for the correction of cranial bones that are comprised of several different designs and components intended for bone stabilization and elongation through distraction osteogenesis. It is composed of multiple sizes and shapes of distractor footplates and either fixed or detachable activator arms. The devices are positioned internally with a connected activation arm extending through the soft tissue for external activation. Some devices, due to their anatomical positioning, are directly activated using a patient activation driver, eliminating the need for attaching an activation arm to the device. The distractor footplates are fixated to the bone on either side of the osteotomy using previously cleared bone screws (K943347, K944561, K944565, K971297, K060177). Distraction is achieved by rotating the distractor threaded drive screws with the patient driver, often with an activation arm, which causes a separation of the distractor footplates and induces the body to grow bone and expand soft tissue as a response. Various lengths of distractor drive screws are available to achieve the desired distraction length. Upon completion of distraction and consolidation of the bone, the screws are removed from the footplates and the distractor is explanted.

The sterile plate and screw kit configurations for use with the Bioplate® Titanium Fixation System are intended for use on non-load bearing fixation, including cranial bone fixation and brow fixation and the treatment of fractures and reconstructive procedures of the craniomaxillofacial skeleton. Each device is intended for single use only and only in conjunction with other titanium and titanium alloy implant

The Bioplate® Titanium Fixation System includes a variety of plate configurations for different anatomical applications. Unalloyed commercially pure Grade 1, Grade 2 and Grade 4 titanium and titanium allov plates, and titanium allov screws of varying diameters and lengths are included for fixation of the plates to the craniomaxillofacial bony tissues. These materials have been implanted safely for many years. The predicate device had been approved under K022033.

The bone plates will be manufactured of unalloyed, commercially pure titanium and titanium 6A1-4V Eli alloy. The materials adhere to the American Society of Testing and Materials (A.S.T.M.) F67 Standards and the American Society of Testing and Materials ( A.S.T.M.) F136 Standard.. The screw will be manufactured of a titanium 6A1-4V Eli alloy that meets the American Society of Testing and Materials (A.S.T.M.) F136 Standard.

The plate and screw fit configurations are sterilized by gamma radiation sterilization, using VD Max dose setting method. Successful completion of sterilization validation and packaging validation studies provides a high level of assurance that sterility of the device has been achieved and can be maintained.

The provided text is a 510(k) summary for a medical device (Modified Sterile Plate & Screw Kit Configurations for use with the Bioplate® Titanium Fixation System) and primarily focuses on establishing substantial equivalence to predicate devices, rather than presenting a performance study with specific acceptance criteria as would typically be seen for a new or novel device.

Therefore, the document does not contain the information requested regarding:

1. A table of acceptance criteria and reported device performance.
2. Sample size used for the test set and data provenance.
3. Number and qualifications of experts for ground truth establishment.
4. Adjudication method for the test set.
5. Multi-reader multi-case (MRMC) comparative effectiveness study or effect size.
6. Standalone (algorithm-only) performance.
7. Type of ground truth used (e.g., pathology, outcomes).
8. Sample size for the training set.
9. How ground truth for the training set was established.

Instead, the document states:

• Comparison of the device's technological characteristics with those of the predicate devices: "All the technical characteristics of the sterile plate and screw kit configurations for use Bioplate® Titanium Fixation System are substantially equivalent to the corresponding characteristics of the predicate devices, and any minor differences raise no new issues of safety and efficacy."
• The materials used have been implanted safely for many years.
• Sterilization validation and packaging validation studies were successfully completed, providing a high level of assurance of sterility.

The "acceptance criteria" in this context are effectively demonstrating that the device is substantially equivalent to legally marketed predicate devices, meaning it has the same intended use, similar technological characteristics, and raises no new questions of safety or effectiveness. The study proving this involves comparing the new device's specifications (materials, sterilization method, intended use) against those of established predicate devices.
