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.
Acceptance Criteria (from ASTM/FDA Guidance) | Reported Device Performance (Summary from Submission) |
---|---|
Magnetically induced displacement force within acceptable limits (ASTM F2052-21) | Not explicitly quantified but implied as acceptable for MR Conditional labeling. |
Magnetically induced torque within acceptable limits (ASTM F2213-17) | Not explicitly quantified but implied as acceptable for MR Conditional labeling. |
Image artifacts within acceptable limits (ASTM F2119-07, R2013) | Not explicitly quantified but implied as acceptable for MR Conditional labeling. |
RF-induced heating (ASTM F2182-19e2) resulting in a temperature rise below 6 ℃ | Achieved under specified scanning conditions: 1.5 T/64 MHz and 3 T/128 MHz at a whole-body averaged specific absorption rate (wbSAR) of 2 W/kg or head SAR of 3.2 W/kg for an hour-long scanning session. |
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 provided text discusses the KLS Martin Orthopedic Implants - MR Conditional device and the studies conducted to support its conditional safety in a Magnetic Resonance (MR) environment.
Here's a breakdown of the requested information based on the provided text:
1. A table of acceptance criteria and the reported device performance
Acceptance Criteria (Hazard addressed) | Standard/Method | Reported Device Performance |
---|---|---|
Magnetically induced displacement force | ASTM F2052-21 | Non-clinical testing provided to support conditional safety in MR environment. (Implied acceptability based on submission) |
Magnetically induced torque | ASTM F2213-17 | Non-clinical testing provided to support conditional safety in MR environment. (Implied acceptability based on submission) |
Image artifacts | ASTM F2119-07, R2013 | Non-clinical testing provided to support conditional safety in MR environment. (Implied acceptability based on submission) |
RF-induced heating | ASTM F2182-19e2 (with Computational modeling and simulation) | Temperature rise below 6°C for an hour-long scanning session at a whole-body averaged specific absorption rate (wbSAR) of 2 W/kg (or head SAR for relevant regions). |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The text does not specify a "test set" in the traditional sense of a clinical or observational study with a certain number of patients or cases. Instead, the performance evaluation is based on non-clinical testing and computational modeling and simulation (CM&S) of the devices themselves.
- Sample size for non-clinical testing: The text refers to "the entire portfolio of KLS Martin thoracic and hand osteosynthesis implants." While not a specific number, it implies a comprehensive evaluation of the range of devices.
- Data provenance: The studies are non-clinical, done ex-vivo (for some tests) and through simulation. The computational modeling utilized "MED Institute's FDA-qualified Medical Development Tool (MDDT) and in a clinically relevant position within the Duke virtual human anatomy." This suggests the data is generated through established scientific methods rather than patient data from a specific country or retrospective/prospective collection.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This question is not applicable in the context of this submission. The "ground truth" for non-clinical testing and simulation is defined by the physical properties of the materials, the established testing standards (ASTM), and the validated computational models. There were no human experts establishing ground truth for evaluating the device's MR compatibility in the way radiology images would be reviewed.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This question is not applicable as there was no human adjudication of a clinical test set. The evaluation relies on standardized testing protocols and validated computational models.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This question is not applicable. This submission is for the MR Conditional labeling of orthopedic implants, not an AI-powered diagnostic device. Therefore, no MRMC study or AI assistance evaluation was performed.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
A "standalone" performance in the context of an algorithm is not applicable here. The computational modeling and simulation for RF-induced heating could be considered a form of "algorithm only" evaluation for a specific physical property of the device, but it is not an AI diagnostic algorithm. It's a scientific modeling approach to predict a physical outcome.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The ground truth for the non-clinical tests and simulations is based on:
- Physical properties and behavior of materials according to established scientific principles.
- Standardized test methods defined by ASTM (e.g., ASTM F2052-21, ASTM F2213-17, ASTM F2119-07, ASTM F2182-19e2).
- FDA-qualified Medical Development Tool (MDDT) for computational modeling, implying its results are considered reliable and accurate.
8. The sample size for the training set
This question is not applicable as there is no mention of a "training set" in the context of artificial intelligence or machine learning. The studies described are non-clinical hardware tests and physics-based simulations, not data-driven AI model training.
9. How the ground truth for the training set was established
This question is not applicable for the same reasons as #8.

The KLS Martin CranioXpand Spring system is indicated for use in the treatment of cranial conditions such as craniosynostosis and congental deficiencies in which osteotomies and gradual bone distraction are indicated for the infant pediatric subpopulation (29 days of age). The CranioXpand implants are implantable single-use products intended for temporary stabilization of the bony cranial roof during and after surgery. This device is intended to be removed after bone consolidation.
The KLS Martin CranioXpand Spring System consists of implantable spring distractors and supporting instruments intended for temporary stabilization and distraction of the bony cranial roof during and after surgery through distraction osteogenesis. The CranioXpand Springs are offered in various sizes. The spring features include rounded atraumatic contours to ensure optimal embedding in soft tissue with curved ends to ensure the devices can securely anchor in the bone. Two springs are provided as part of the CranioXpand system for anterior and posterior placement on the osteotomies. The springs are removed after adequate bone formation or after the bone consolidation phase is complete. These devices are typically left in the implanted location for 3 - 6 months before explantation. The CranioXpand Instruments are accessories used to facilitate spring size selection, and spring insertion and positioning.
The provided text is a 510(k) Premarket Notification from the FDA, specifically concerning the KLS-Martin L.P. CranioXpand device. This document focuses on demonstrating substantial equivalence to a predicate device, rather than proving the device meets clinical performance acceptance criteria through the types of studies you've queried (e.g., MRMC studies, standalone AI performance, expert ground truth adjudication).
The CranioXpand device is a physical implant (spring system) used for cranial conditions in pediatric patients, not an AI or software-based diagnostic tool. Therefore, the types of studies and acceptance criteria you've asked about, which are common for AI-driven image analysis or diagnostic devices, are not applicable to the information contained within this 510(k) submission.
The "studies" conducted for this device are non-clinical performance bench testing and biocompatibility testing, designed to show that the CranioXpand is as safe and effective as its predicate device.
However, I can extract the information relevant to their acceptance criteria and performance studies for this type of medical device:
Here's a breakdown based on the provided document:
1. Acceptance Criteria and Reported Device Performance
The acceptance criteria for the CranioXpand device, as reported in this 510(k), are focused on bench testing to demonstrate performance equivalence to the predicate device and biocompatibility.
Acceptance Criteria Category | Specific Criteria | Reported Device Performance |
---|---|---|
Biocompatibility | Compliance with ISO 10993-1:2018 for long-term implants in contact with tissue/bone for the springs, and external communicating devices with limited contact for the instruments, covering endpoints such as cytotoxicity, sensitization, irritation, pyrogenicity, carcinogenicity, implantation, acute/subacute/subchronic/chronic toxicity. | The CranioXpand device and accessories were evaluated per FDA guidance "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management Process" and found to comply with the requirements of ISO 10993-1:2018 thus are considered biocompatible. |
Spring Testing (Performance Bench Test) | Force measurements during cyclical testing (compressing to 10mm, holding 5s, decompressing, repeated 6 times) must show performance comparable to the predicate device. The exact quantitative criteria for "comparable" are not explicitly stated, but the conclusion is a "Pass." | "A comparison of the performance of the subject and predicate springs via force measurements during cyclical testing was conducted... The acceptance criteria of the test were met, thus demonstrating that the performance of the subject device is substantially equivalent to that of the predicate device." Concluded: Pass |
Insertion Instruments Testing | Instrument must appropriately open, close, and pick up the spring. Measurements to verify the instrument could compress spring legs sufficiently ( |

This document is a 510(k) summary for the KLS Martin LINOS Wrist System. It outlines the device's characteristics, intended use, and compares it to legally marketed predicate devices to demonstrate substantial equivalence.
Here's an analysis of the provided text in relation to acceptance criteria and study proving device performance:
Crucially, this document does not describe an AI/ML medical device. It describes a traditional Class II orthopedic implant (metallic bone fixation appliance). Therefore, many of the typical acceptance criteria and study aspects for AI/ML devices (like MRMC studies, ground truth establishment for algorithms, training/test set sizes for algorithms, expert adjudication methods for AI performance, etc.) are not applicable to this submission.
The acceptance criteria and study described here are for the mechanical and biocompatibility performance of a physical medical device.
Acceptance Criteria and Device Performance (for a physical orthopedic implant)
Since this is a physical medical device and not an AI/ML algorithm, the "acceptance criteria" table below reflects the types of performance metrics that would be relevant for such a device, and how its performance is typically proven.
Acceptance Criteria Category | Specific Acceptance Criteria (Generalized for Orthopedic Implants) | Reported Device Performance (from the document) |
---|---|---|
Mechanical Performance | Equivalent or superior static and dynamic strength compared to predicate device. | "Comparative head-to-head static and dynamic bench testing was conducted on the subject and predicate...to determine that the subject device has equivalent performance to the primary predicate." "Mechanical test results demonstrate that the KLS Martin LINOS Wrist System's performance is substantially equivalent to the primary predicate device." |
Screw Performance | Equivalent or superior torsional strength, drive torque, and pullout strength compared to predicate. | "Additionally, comparative screw testing was performed to evaluate torsional strength, drive torque, and pullout strength in accordance with ASTM F543." (Implicitly, the results met the equivalence standard for substantial equivalence). |
Biocompatibility | Device materials are biocompatible and appropriate for intended use. | "Biological safety risk assessments in compliance with ISO 10993-1:2018 were completed on the subject devices and concluded the devices are biocompatible and appropriate for their intended use." |

Shelf Life | Proven shelf life for sterile components. | "Shelf life for all gamma sterilized components is five (5) years from the date of sterilization." |
Study Information (as applicable to a non-AI/ML medical device 510(k))
Since the provided document is a 510(k) summary for a physical orthopedic implant, not an AI/ML device, many of the requested points below (especially those related to AI/ML specific studies like MRMC or standalone algorithm performance) are not applicable or are addressed by the foundational regulatory framework for traditional medical devices.
-
Sample size used for the test set and the data provenance:
- Test Set (for mechanical testing): The document states "Comparative head-to-head static and dynamic bench testing was conducted on the subject and predicate...". It doesn't specify the exact sample size (N number of implants tested), but standard mechanical testing for medical devices typically involves a statistically robust number of samples to demonstrate equivalence or superiority according to relevant ISO/ASTM standards.
- Data Provenance: The studies are bench tests conducted in a laboratory setting, not on patient data. Thus, "country of origin of the data" or "retrospective/prospective" clinical study design are not relevant in this context. The "data" are mechanical test results.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not Applicable. For a physical implant device proving mechanical performance, "ground truth" is established by adherence to recognized engineering standards (ASTM, ISO) for material properties, mechanical strength, and biocompatibility. Experts involved would be engineers, material scientists, and toxicologists conducting the tests and interpreting results against these standards, not clinicians establishing "ground truth" on patient images or outcomes.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not Applicable. This concept is critical for establishing ground truth in clinical data, especially for AI/ML devices where reader variability exists. For mechanical bench testing, results are objective measurements against defined criteria and standards; adjudication of "readings" is not relevant.
-
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 type of study specifically for evaluating the performance of AI/ML diagnostic or prognostic tools when used by human readers (e.g., radiologists interpreting images). The KLS Martin LINOS Wrist System is a surgical implant; it does not involve diagnostic image interpretation or AI assistance for human readers.
- The document explicitly states: "Clinical testing was not necessary for the determination of substantial equivalence." This reinforces that the evaluation was based on non-clinical (bench) testing.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not Applicable. Again, this pertains to an AI/ML algorithm's performance. The device is a physical implant.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For this physical medical device, "ground truth" for proving substantial equivalence relies on:
- Standardized Mechanical Test Results: Comparing the device's measured mechanical properties (strength, torque, pullout) to those of the predicate device, as defined by ASTM and ISO standards.
- Biocompatibility Standards (ISO 10993-1:2018): Ensuring the materials meet safety criteria for biological interaction.
- Sterilization Standards (ISO 11137, ISO 17665): Demonstrating the effectiveness of the sterilization process.
- Packaging Standards (ISO 11607, ASTM D4169): Verifying package integrity and shelf life.
- For this physical medical device, "ground truth" for proving substantial equivalence relies on:
-
The sample size for the training set:
- Not Applicable. This concept is for AI/ML models. This device does not use a training set.
-
How the ground truth for the training set was established:
- Not Applicable. This concept is for AI/ML models. This device does not use a training set.

The KLS Martin Level One Rib Fixation System is indicated for use in the stabilization and rigid fixation of rib fractures in the chest wall including reconstructive procedures, trauma, or planned osteotomies in patients 18 years of age or older.
The KLS Martin Level One Rib Fixation System is comprised of PEEK plates and titanium locking screws intended to provide rigid fixation of bone in the thoracic anatomy. The PEEK plates are pre-contoured to accommodate patient anatomy and are offered in plate thicknesses of 2 mm - 3 mm. The PEEK plates are compatible with the Ti-6Al-4V (ASTM F136) 2.3 mm x 7 mm multidirectional locking screws offered in the system. The plates are manufactured from PEEK (ASTM F2026). The system includes the necessary instrumentation
The provided text describes a 510(k) premarket notification for the KLS Martin Level One Rib Fixation System. It focuses on establishing substantial equivalence to predicate devices based on non-clinical performance data and discussions of intended use and technological characteristics.
However, the provided document DOES NOT contain information regarding a study involving AI/algorithm performance for a diagnostic or AI-assisted device. Therefore, I cannot extract the specific details requested in your prompt regarding acceptance criteria and performance studies for an AI device.
The document primarily addresses the substantial equivalence of a physical medical device (rib fixation system) based on mechanical and biological safety testing, rather than a diagnostic or AI-driven system.
Therefore, many of the requested points, such as "table of acceptance criteria and the reported device performance" (for an AI device), "sample size used for the test set and the data provenance," "number of experts used to establish the ground truth," "adjudication method," "MRMC comparative effectiveness study," "standalone performance," "type of ground truth," "sample size for the training set," and "how the ground truth for the training set was established," are not applicable to the content provided.
The non-clinical performance data mentioned refers to:
- Comparative head-to-head bench testing: To determine if the subject device performs equivalently to or better than the primary predicate device in pull-out system testing.
- Comparison to a reference device (Synthes MatrixRIB Fixation System): For pull-out system testing.
- Biological safety risk assessments: In compliance with ISO 10993-1:2018, concluding the devices are biocompatible.
The document explicitly states: "Clinical testing was not necessary for the determination of substantial equivalence." This further confirms that no human-in-the-loop or standalone diagnostic performance studies were conducted or reported in this 510(k) summary.

KLS Martin L.P.
The KLS Martin Pure Pectus System is indicated for use in surgical procedures to repair pectus excavatum. It is indicated for use in adult and pediatric (children and adolescents) populations.
The KLS Martin LP Pure Pectus system consists of metallic implants comprised of straight and angled pectus bars and connector bars that provide support to the thoracic cavity undergoing repair for pectus excavatum. The implants are provided non-sterile in multiple sizes and are manufactured using tradition methods. Pectus bars are manufactured from CP Titanium. Connector bars are manufactured from Ti-6Al-4V. The system also instruments to facilitate placement of the implants.
The KLS Martin Pure Pectus System is a metallic implant system designed for surgical repair of pectus excavatum in both adult and pediatric populations. The submission K221938 received FDA clearance. Given the information provided, here's a detailed breakdown of the acceptance criteria and the study that proves the device meets those criteria:
1. Table of Acceptance Criteria and Reported Device Performance
Since this is a 510(k) submission and not a standalone algorithm, the "acceptance criteria" are not reported as specific performance metrics like sensitivity, specificity, or AUC, as would be the case for an AI/ML device. Instead, the acceptance criteria are related to mechanical and biological performance designed to demonstrate substantial equivalence to an existing predicate device.
Acceptance Criteria Category | Specific Acceptance Criteria (Inferred from Report) | Reported Device Performance (as stated in the document) |
---|---|---|
Mechanical Performance (Static Load) | Equivalent or superior static 4-point bending performance compared to the primary predicate device (Lorenz Pectus Support Bar K972420). Detailed thresholds for deflection, failure load, or stiffness would have been defined in test protocols, but are not explicitly reported in this summary document. | "Comparative head-to-head bench testing was conducted to determine substantial equivalence to the primary predicate device in static and dynamic 4-point bending. The testing met all predetermined acceptance criteria and the results demonstrate that the subject device's performance is substantially equivalent to the primary predicate device." |
Mechanical Performance (Dynamic/Fatigue Load) | Equivalent or superior dynamic (fatigue) 4-point bending performance compared to the primary predicate device. Detailed thresholds for fatigue life or fracture mechanics would have been defined. | Same as above. |
Biocompatibility | Biocompatible for its intended use, complying with ISO 10993-1:2018 standards for medical devices with prolonged tissue contact. No unacceptable cytotoxic, genotoxic, sensitization, irritation, or systemic toxicity effects. | "Biological safety risk assessments in compliance with ISO 10993-1:2018 were completed on the subject devices and concluded the devices are biocompatible and appropriate for their intended use." |
Material Properties | Acceptable material composition (CP Titanium and Ti-6Al-4V) that does not adversely affect safety and effectiveness compared to the predicate's stainless steel. | "The subject device is manufactured from CP titanium (ASTM F67:2017) and Ti-6Al-4V (ASTM F136:2013) and the predicate device is manufactured from stainless steel. Performance testing demonstrated that the differences in material does not affect the safety and effectiveness of the subject devices and can be determined substantially equivalent." |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: Not explicitly stated as a number of "cases" or "patients" because this was bench testing on physical devices, not a clinical trial or algorithm evaluation with data. The sample size would refer to the number of bars tested for each mechanical test (static and dynamic bending). While not specified, these types of tests typically involve a statistically significant number of samples per variant (e.g., 5-10 samples per size/configuration for fatigue, 3-5 for static).
- Data Provenance: The data provenance is from non-clinical "bench testing" conducted by the manufacturer, KLS Martin L.P. This is not patient data; it's laboratory test data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. For this type of submission (mechanical and biocompatibility testing for a medical device), "ground truth" is not established by human experts in the way it would be for an AI diagnostic algorithm. Ground truth is established by validated laboratory testing procedures and international standards.
4. Adjudication Method for the Test Set
Not applicable. This was not an expert review/adjudication of clinical images or patient cases. The "adjudication" in this context is the comparison of test results against pre-defined acceptance criteria per established test protocols and standards.
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 type of study is relevant for AI/ML diagnostic tools that assist human readers in interpreting medical images or data. The KLS Martin Pure Pectus System is a metallic implant; its evaluation focused on its physical and biological performance, not its interpretive capabilities.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
No, a standalone performance evaluation was not done. This is also not relevant for an implantable medical device. Standalone performance is assessed for algorithms that provide diagnostic or prognostic outputs without human oversight.
7. The Type of Ground Truth Used
For the mechanical testing, the "ground truth" is the measured physical properties and performance of the subject device compared against the measured physical properties and performance of the predicate device, with both tested under standardized conditions. The benchmark for "ground truth" for biocompatibility is conformance to ISO 10993-1:2018 standards.
8. The Sample Size for the Training Set
Not applicable. This device is not an AI/ML algorithm that requires a "training set."
9. How the Ground Truth for the Training Set Was Established
Not applicable. This device is not an AI/ML algorithm that requires a "training set" or ground truth for training.

KLS Martin L.P.
KLS Martin IPS Distraction includes devices intended as bone stabilizers and lengthening (and or transport) devices for correction of congenital deficiencies or post traumatic defects of the mandible (including ramus, body, alveolar ridge, palate, and symphysis) and mid-face bones that require gradual distraction in adults, adolescents, children and infants weighing more than 2.5 kg.
KLS Martin IPS Distraction System is comprised of patient-specific models, guides and distraction footplates used in conjunction with previously cleared distractor bodies and metallic bone screws for internal fixation and reconstruction of maxillofacial / midface and mandibular bones. The devices are manufactured based on medical imaging (CT scan) of the patient's anatomy with input from the physician during virtual planning and prior to finalization of the device. The physician only provides input for model manipulation and interactive feedback by viewing digital models of planned outputs that are modified by trained KLS Martin personnel during the planning session. For each design iteration, verification is performed by virtually fitting the generated device model over a 3D model of the patient's anatomy to ensure its dimensional properties allow an adequate fit.
Implants are provided sterile or non-sterile, range in thickness from 0.6 - 10 mm, and are manufactured using additive or traditional (subtractive) methods from either CP Titanium (ASTM F67) or Ti-6A1-4V (ASTM F136) materials. These patient-specific devices are fixated with previously cleared KLS Martin screws.
This document describes the 510(k) summary for the KLS Martin IPS Distraction device. It provides information regarding the device's indications for use, technological characteristics, and a comparison to predicate and reference devices to support a claim of substantial equivalence.
Based on the provided text, the device in question is a medical implant (bone plates) designed for cranial and facial bone distraction. Therefore, the acceptance criteria and study proving its performance will relate to its mechanical properties, biocompatibility, sterilization, software validation, and clinical safety and effectiveness for its intended patient population.
Here's an analysis of the provided text to extract the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not present a formal table of acceptance criteria with corresponding performance metrics in a pass/fail format. Instead, it describes various tests performed and their outcomes in narrative form to demonstrate substantial equivalence. I will infer the "acceptance criteria" from the types of tests conducted and the "reported device performance" from the stated results.
Acceptance Criteria (Inferred) | Reported Device Performance |
---|---|
Mechanical Strength (Weld Strength): Withstand forces reflecting clinical use for different material combinations. | A direct comparison weld strength test was performed. The titanium alloy/titanium alloy material combination (subject device) was able to withstand a greater tensile load than the CP titanium alloy material combination (predicate/reference devices). |
Biocompatibility: Meet ISO 10993 standards for biological safety (cytotoxicity, sensitization, chemical analysis, material characterization). | Biocompatibility testing (cytotoxicity, chemical analysis, sensitization, and chemical/material characterization) was leveraged from K191028 (reference device) for titanium devices. The subject devices are similar in final finished form, material formulations, manufacturing methods, and sterilization methods. The report states this adequately addresses biocompatibility. |
Sterilization: Achieve a specified sterility assurance level (SAL). | Steam sterilization validations were performed according to ISO 17665-1:2006 to a sterility assurance level (SAL) of 10^-6 (standard is 10^-6, not 10^-9 as written, likely a typo in the document or a more stringent internal target) using the biological indicator (BI) overkill method. All test method acceptance criteria were met. Validations for titanium devices were leveraged from the reference device K191028, as subject devices are similar. |
Pyrogenicity: Ensure endotoxin levels are below specified limits. | LAL endotoxin testing was conducted according to AAMI ANSI ST72:2019. The results demonstrate that the subject devices contain endotoxin levels below the USP allowed limit for medical devices and meet pyrogen limit specifications. This testing was leveraged from the reference device K191028 due to similar materials and processes. |
Software Verification and Validation: Ensure software used for planning and design functions correctly and meets requirements. | Software verification and validation was performed on each individual software application. Quality and on-site user acceptance testing provide objective evidence that all software requirements and specifications were implemented correctly and completely and are traceable to system requirements. Risk analysis and impact assessments showed conformity with pre-defined specifications and acceptance criteria. Software documentation demonstrates mitigation of potential risks and performance as intended. |
Clinical Performance (Pediatric Subpopulations): Demonstrate safety and effectiveness in pediatric patients. | Risk mitigation assessments based on FDA guidance "Premarket Assessment of Pediatric Medical Devices" were completed. 5 clinical studies were analyzed as supporting evidence. The conclusion is that the device can be used for infants (>2.5 kg), children, and adolescents (29 days through 21 years) if additional precautions are taken into account (e.g., avoiding permanent implants in skeletally immature patients, low-dose CT protocols). |
2. Sample Size Used for the Test Set and the Data Provenance
- Mechanical Testing (Weld Strength): The document does not specify the exact sample size for the weld strength test. It states "A direct comparison weld strength test was performed," implying sufficient samples for a comparative analysis, but no number is given.
- Biocompatibility, Sterilization, Pyrogenicity: These tests leveraged data from a previously cleared device (K191028). No new sample sizes are explicitly mentioned for these, as the substantial equivalence hinges on the similarity to the already-tested reference device. If new samples were tested for verification, their numbers are not stated.
- Software V&V: No specific sample size (e.g., number of cases or simulations) is mentioned for software testing. It refers to "all software requirements and specifications" and "on-site user acceptance testing."
- Clinical Performance (Pediatric): 5 clinical studies were analyzed to support the pediatric indications. The document lists the studies, but does not state how many patients were in the "test set" for the KLS Martin device specifically. These appear to be literature reviews, not new clinical trials conducted for this device clearance.
- Data Provenance: The provenance of the data for the 5 analyzed clinical studies is implied to be from published literature ("Based on published literature findings"). Specific country of origin is not mentioned, nor is whether the studies were retrospective or prospective, though typical clinical trials are prospective, and reviews can be of either.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
- Mechanical, Biocompatibility, Sterilization, Pyrogenicity, Software V&V: The document does not mention the use of external "experts" to establish ground truth for these non-clinical performance tests. These are typically assessed against pre-defined engineering and biological standards by internal or contract testing labs.
- Clinical Performance (Pediatric): The "ground truth" for the pediatric clinical performance is based on "published literature findings" and risk assessments performed based on FDA guidance. There is no mention of a specific number of experts used to establish a new ground truth for this 510(k) submission's test set. The experts are implicitly the authors of the peer-reviewed clinical literature analyzed and the regulatory/clinical affairs personnel conducting the risk assessment. Qualifications of these implied experts are not detailed in this document.
4. Adjudication Method for the Test Set
- No adjudication method (e.g., 2+1, 3+1) is described for any of the tests, as these are technical performance tests or literature reviews, not studies involving human interpretation of medical images or data requiring reader consensus.
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 mentioned or performed. This device is a passive implantable device, not an AI-assisted diagnostic tool.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
- This question is not applicable. The device is a surgical implant, not a software algorithm. The software mentioned (for planning and design) is a tool for manufacturing patient-specific implants, not a diagnostic algorithm in itself that would have standalone performance.
7. The Type of Ground Truth Used
- Mechanical Testing: Ground truth is implicitly defined by engineering standards for tensile strength and material properties.
- Biocompatibility: Ground truth is established by the accepted international standard ISO 10993 series.
- Sterilization: Ground truth is defined by the accepted international standard ISO 17665-1:2006 and a target SAL of 10^-6.
- Pyrogenicity: Ground truth is defined by AAMI ANSI ST72:2019 and USP allowed limits for endotoxins.
- Software V&V: Ground truth is established by pre-defined software requirements, specifications, and risk assessment outcomes.
- Clinical Performance (Pediatric): Ground truth for the safety and effectiveness in pediatric applications is based on peer-reviewed clinical literature and FDA guidance on pediatric medical devices, interpreted through a risk assessment. This is a form of outcomes data and expert consensus derived from previous studies, rather than a new "ground truth" adjudicated for this submission.
8. The Sample Size for the Training Set
- This question is not applicable to an implantable device like KLS Martin IPS Distraction. "Training set" usually refers to data used to train a machine learning algorithm.
- For the patient-specific design, the "training" data is the individual patient's CT scan. Each device's design is unique to the patient's anatomy. The "training" for the process comes from accumulated experience, validated software, and adherence to design specifications described in the section about patient-specific manufacturing.
9. How the Ground Truth for the Training Set was Established
- This question is not applicable for the reasons stated above. For the individual patient design process, the "ground truth" (the patient's anatomy for which the device is being designed) is established directly from the patient's CT scan data. The "virtual planning" involves interactions between the physician and trained KLS Martin personnel to refine the design, with "verification" performed by virtually fitting the generated device model over a 3D model of the patient's anatomy to ensure adequate fit.

KLS-Martin L.P.
KLS Martin Individual Patient Solutions (IPS) is intended as a pre-operative software tool for simulating / evaluating surgical treatment options as a software and image segmentation system for the transfer of imaging information from a medical scanner such as a CT based system. The is processed by the IPS software and the result is an output data file that may then be provided as digital models or used as input in an additive manufacturing portion of the system that produces physical outputs including implants, anatomical models, guides, splints, and case reports for use in maxillofacial, midface, & mandibular surgery.
KLS Martin Individual Patient Solutions (IPS) implant devices are intended for use in the stabilization, fixation, and reconstruction of the maxillofacial / midface and mandibular skeletal regions in children (2 years of age), adolescents (12 years of age - 21 years of age), and adults.
KLS Martin Individual Patient Solutions (IPS) is comprised of a collection of software and associated additive manufacturing equipment intended to produce various outputs to support reconstructive and orthognathic surgeries. The system processes the medical images to produce various patient-specific physical and/or digital output devices which include implants, anatomical models, guides, splints, and case reports.
Patient-specific metallic bone plates are used in conjunction with metallic bone screws for internal fixation of maxillofacial, midface, and mandibular bones. The devices are manufactured based on medical imaging (CT scan) of the patient's anatomy with input from the physician during virtual planning and prior to finalization and production of the device. The physician provides input for model manipulation and interactive feedback by viewing digital models of planned outputs that are modified by trained KLS Martin engineers during the planning session. For each design iteration, verification is performed by virtually fitting the generated output device over a 3D model of the patient's anatomy to ensure its dimensional properties allow an adequate fit.
Implants are provided non-sterile and are manufactured using traditional (subtractive) or additive manufacturing methods from either CP Titanium (ASTM F67) or Ti-6AI-4V (ASTM F136). These patient-specific devices are fixated with previously cleared KLS Martin screws.
