    AI/ML Overview

    This document is a 510(k) summary for a medical device (Renovis Surgical Hip Replacement System), not a clinical study report. Therefore, it does not contain the information required to answer your questions regarding acceptance criteria and a study proving device performance in the context of an AI/human-in-the-loop system.

    The document discusses the substantial equivalence of an expansion to an existing device (Extended Lateral Offset Femoral Stems) to previously cleared predicate devices. It relies on bench performance testing and material equivalence, rather than a clinical study with human subjects or AI-assisted diagnostic performance.

    Here's why the requested information cannot be extracted from this document:

    • AI/Machine Learning Context: The document is about a physical medical device (hip prosthesis components), not a software or AI-driven diagnostic/decision support system. Therefore, concepts like "acceptance criteria" for AI performance, "test set," "training set," "ground truth," "experts," or "MRMC studies" are not applicable in this context.
    • Study Type: The "study" mentioned is "Performance Testing - Bench," which refers to laboratory tests of the device's physical properties and durability, not clinical trials or comparative effectiveness studies involving human readers or AI.
    • Device Performance: The "reported device performance" refers to successful completion of specific ISO and ANSI/AAMI standards for physical and sterilisation properties, not diagnostic accuracy metrics (e.g., sensitivity, specificity, AUC).

    Summary of what can be extracted, and why the rest cannot:

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

      • Acceptance Criteria (implicit): Compliance with ISO 7206-4, ISO 7206-6, ANSI/AAMI/ISO 11137-1, ANSI/AAMI/ISO 11137-2, ANSI/AAMI ST72:2011(R)2016 for bacterial endotoxin testing, and material standards like ASTM F136-13, ASTM A564-13, ASTM A276-17.
      • Reported Device Performance: "Renovis successfully completed the following performance tests." (Lists the standards). "endotoxin limits are in compliance with ANSI/AAMI ST72:2011(R)2016." The results indicate the device met the requirements of these standards.
      • Why partial: These are engineering and material performance criteria for a physical implant, not diagnostic performance metrics for an AI system.
    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

      • Cannot be provided. This refers to bench testing of physical components, not a clinical study or AI model evaluation. There is no "test set" of patient data in the sense you're asking about.
    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):

      • Cannot be provided. This is not relevant to a physical device's bench testing. "Ground truth" in this context would be physical measurements and material properties confirmed by engineering and quality control experts, not clinical diagnosis.
    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

      • Cannot be provided. This is for clinical or AI performance evaluation, not bench testing.
    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:

      • Cannot be provided. This type of study is for AI-assisted diagnostic tools, not physical implants.
    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • Cannot be provided. This is about an algorithm's performance, which is not applicable to this device.
    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

      • Cannot be provided (in the AI/clinical sense). For bench testing, the "ground truth" is adherence to established engineering standards (e.g., fatigue limits, material composition specifications).
    8. The sample size for the training set:

      • Cannot be provided. There is no "training set" for a physical device in this context, as there is no AI model being trained.
    9. How the ground truth for the training set was established:

      • Cannot be provided. Not applicable.

    In conclusion, the provided FDA document is for a traditional medical device (hip prosthesis) and focuses on engineering, material, and sterilization compliance, not AI algorithm performance or clinical diagnostic accuracy.

    Intended Use

    The Renovis S141 Lumbar Interbody Fusion is indicated for intervertebral body fusion procedures in skeletally mature patients with degenerative disc disease (DDD) of the lumbar spine at one or two contiguous levels from L2-S1. Degenerative disc disease is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These DDD patients may have up to Grade 1 spondylolisthesis at the involved level(s). Renovis S141 System implants are to be used with autogenous bone graft. Patients should be skeletally mature and have at least six months of non-operative treatment. The Renovis S141 System must be used with supplemental fixation cleared by FDA for use in the lumbar spine.

    Device Description

    The Renovis S141 Lumbar Interbody Cage System is FDA cleared as K143126. This application describes a manufacturing change to the K143126 S141 Ti6Al4Vcages; internal dimensional changes; additional cages geometries; and a packaging change. The new name of the system is the Renovis S141 Lumbar Interbody Fusion System (S141 System).

    The S141 System includes cages of a variety of lengths, widths, heights, and lordosis to suit the individual pathology and anatomical conditions of the patient. The different shape of the footprint allows for different surgical approaches for insertion.

    The Ti6Al4V is compliant with ASTM F136-13 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications.

    The system also includes instruments which are manufactured from stainless steel in compliance with ASTM A564-13 Standard Specification for Hot-Rolled and Cold-Finished Age-Hardening Stainless Steel Bars and Shapes.

    AI/ML Overview

    This document describes the Renovis S141 Lumbar Interbody Fusion System, a medical device, and primarily focuses on its substantial equivalence to a predicate device, rather than providing details on a study that proves its performance against acceptance criteria in the context of algorithm-based device performance. The information provided is for a 510(k) premarket notification, which establishes substantial equivalence to a legally marketed predicate device, not necessarily a performance study against predefined acceptance criteria for an AI/algorithm-driven device.

    Therefore, many of the requested sections related to acceptance criteria for algorithmic performance, sample sizes for test sets, expert ground truthing, MRMC studies, and standalone algorithm performance cannot be extracted from this document, as they are not applicable to the type of information presented.

    However, I can provide information based on what is available in the document regarding the device's characteristics and the types of testing performed for substantial equivalence.

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

    The document does not explicitly state acceptance criteria for the device in the format of a clinical or algorithmic performance study with specific metrics (e.g., sensitivity, specificity, AUC). Instead, it relies on substantial equivalence to a predicate device and bench testing results. The "performance" reported relates to the mechanical and biological safety of the modified device components.

    Acceptance Criteria CategorySpecific Test/Performance MetricReported Performance/Outcome
    Material ComplianceASTM F136-13Compliant (for Ti6Al4V)
    Instrument MaterialASTM A564-13Compliant (for stainless steel)

    Bacterial endotoxin testingSuccessfully conducted
    Pyrogenicity testingSuccessfully conducted
    Standard ComplianceAdherence to various ASTM, AAMI/ANSI, ISO standards for materials, testing, and biocompatibility, and FDA Guidance.Compliant

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

    This information is not provided in a way that aligns with an algorithmic device test set. The document refers to "testing" that was "successfully conducted" for mechanical and biological properties. No sample size for a "test set" in the context of data for an algorithm is mentioned. Data provenance (country of origin, retrospective/prospective) is also not applicable or mentioned.

    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)

    Not applicable. This device is a physical implant, not an AI/algorithm-driven diagnostic or prognostic tool that would require expert ground truthing of data.

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

    Not applicable, as there is no "test set" in the context of an algorithm's performance and associated ground truth 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 document is for a physical medical implant (lumbar interbody fusion system), not an AI-assisted diagnostic or therapeutic device. Therefore, MRMC studies are not relevant.

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

    Not applicable. This device is a physical implant, not an algorithm.

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

    Not applicable. The "ground truth" for this device would relate to its physical properties, material composition, and biological safety as measured by laboratory tests and adherence to standards, which are inherently objective measurements rather than interpretations requiring expert consensus on imaging or clinical data.

    8. The sample size for the training set

    Not applicable. This device does not involve a training set as it is not an AI/algorithm-driven system.

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

    Not applicable, as there is no training set for this device.

    Intended Use

    The Renovis Tesera SC Stand-alone Anterior Cervical Fusion (ACF) System is indicated for intervertebral body fusion procedures in skeletally mature patients with cervical degenerative disc disease at one level from C2-T1. Renovis Tesera SC Stand-alone Anterior Cervical Fusion (ACF) System implants are to be used with autogenous bone graft. Patients should be skeletally mature and have at least six weeks of non-operative treatment prior to implantation.

    The Renovis Tesera SC ACF System is a stand-alone system when used with the cover plate and screws provided, and requires no additional supplemental fixation. When used as a stand-alone system, the cages require the use of three (3) screws and the cover plate assembly.

    When used without the cover plate and three screws the Renovis Tesera SC ACF System is a non-stand-alone system and requires additional supplemental fixation cleared by the FDA for use in the cervical spine to augment stability.

    Device Description

    The Renovis Tesera SC Stand-alone Anterior Cervical Fusion (ACF) System includes the Tesera Trabecular Titanium (T3) cages, bone screws (self-drilling and self-tapping options) and anterior cover plate assembly. When used with the cover plate and screws, the Tesera SC ACF System requires no supplementary fixation systems. The screws protrude through the interbody portion of the device into the adjacent vertebral bodies, stabilize the vertebral body and reduce the likelihood of expulsion of the implant. The Tesera Trabecular Titanium (T3) cages have windows in the side for visualization of the bone graft. The accompanying cover plate is designed to resist screw back-out and must be used when the screws are implanted. When used without the cover plate and screws, the Tesera SC ACF cages require supplemental fixation.

    The Renovis Tesera SC ACF System cages are available in a variety of sizes (widths, height, depths, and bone screw sizes) to suit the individual pathology and anatomical conditions of the patient. The cages are additively manufactured then machined from Titanium alloy (Ti-6A1-4V). The bone screws are manufactured from Titanium alloy (Ti-6Al-4V) and the cover plate assembly is manufactured from Titanium alloy (Ti-6Al-4V) and Nitinol alloy. The implants are provided to the end user sterilized through gamma irradiation.

    The system also consists of reusable instrumentation used to implant the cages, screws, and cover plate assembly.

    AI/ML Overview

    This document describes the Renovis Tesera SC Stand-alone Anterior Cervical Fusion (ACF) System, a medical device. The information provided focuses on its substantial equivalence to predicate devices rather than detailing specific acceptance criteria and study results for device performance against those criteria in a tabular format. The FDA 510(k) summary typically assesses substantial equivalence based on similar intended use, design, materials, and performance testing to legally marketed devices, rather than establishing new, specific performance acceptance criteria for each submission.

    However, based on the provided text, I can infer the types of performance criteria addressed through mechanical testing and report the nature of these studies.

    Here's an analysis of the provided information:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not present a formal table of acceptance criteria with corresponding performance results in the way one might see for a diagnostic AI algorithm. Instead, it lists the mechanical performance tests conducted and asserts that "Differences between the Renovis Tesera SC ACF System and the predicate devices do not raise new issues of safety or effectiveness." This implies that the device met the performance expectations established by the predicate devices and relevant ASTM standards.

    Type of Performance TestAcceptance Criteria (Inferred from Standard/Predicate)Reported Device PerformanceComments
    Subsidence (without screws)Meet requirements of ASTM F2267-04Implied to meet requirementsPerformed to demonstrate sufficient resistance to vertical displacement when in service.
    Static CompressionMeet requirements of ASTM F2077-14Implied to meet requirementsAssesses the device's ability to withstand sustained axial forces without failure.

    Finite Element Analysis (cage)Support structural integrity and performanceData used to analyze structural behaviorComputational analysis to predict stress, strain, and deformation under various loads.

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

    The document describes bench testing, meaning the "test set" consists of physical devices subjected to mechanical and material property tests.

    • Sample Size for Test Set: Not explicitly stated for each test, but standard ASTM methods typically define minimum sample sizes for such tests.
    • Data Provenance: This is not applicable in the usual sense for clinical data, as this is mechanical bench testing of devices (not human data). The tests were conducted to evaluate the physical and mechanical properties of the device itself.

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

    Not applicable. For mechanical bench testing, "ground truth" is established by the standardized test methods (e.g., ASTM standards) themselves, which define the conditions, measurements, and interpretation of results. Experts are involved in designing and conducting the tests according to these standards, but there isn't a "ground truth" established by expert consensus on, for example, an image reading.

    4. Adjudication Method for the Test Set

    Not applicable. Adjudication methods (like 2+1 or 3+1) are typically used in clinical studies or expert reviews where there's variability in interpretation (e.g., of medical images) that needs to be resolved to establish a robust ground truth. For mechanical tests, the results are quantitative measurements against predefined standards.

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

    Not applicable. This is a medical device for surgical implantation, not a diagnostic AI algorithm. Therefore, an MRMC study comparing human readers with and without AI assistance is irrelevant to this submission.

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

    Not applicable. This device is a physical implant, not an algorithm.

    7. Type of Ground Truth Used

    For the performance testing mentioned:

    • Mechanical Performance: The "ground truth" is established by adherence to recognized ASTM (and ISO) standards for material properties and mechanical performance. These standards define acceptable ranges for strength, fatigue life, corrosion resistance, etc., for intervertebral body fusion devices.

    8. Sample Size for the Training Set

    Not applicable. This is a physical medical device. There is no "training set" in the context of machine learning algorithms. The design and manufacturing process are refined through engineering principles, material science, and iterative testing, not through a "training set" of data.

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

    Not applicable, as there is no training set for a physical device. The design and manufacturing are based on established engineering principles, material science, and adherence to relevant industry standards for safety and efficacy of medical implants.

    AI/ML Overview

    The provided document describes a 510(k) premarket notification for the Renovis Anterior Cervical Plate System. This is a medical device submission, and the content focuses on demonstrating substantial equivalence to a predicate device rather than describing a study with acceptance criteria and device performance in the way one might for an AI/algorithm-based diagnostic product.

    Therefore, many of the requested categories (e.g., sample size for test set, number of experts, adjudication method, MRMC study, standalone performance, training set details) are not applicable or not provided in this type of document. This document details the physical and mechanical performance of an implantable medical device, not the diagnostic performance of a software or AI.

    However, I can extract the relevant information from the performance testing section.

    Acceptance Criteria and Study for Renovis Anterior Cervical Plate System

    The Renovis Anterior Cervical Plate System is a physical medical device. Its "performance" refers to its mechanical and material properties, not diagnostic accuracy. The "acceptance criteria" are implicitly met by passing the specified ASTM standards and internal protocols.

    Here's a breakdown of the available information:

    1. Table of Acceptance Criteria and Reported Device Performance

    Test PerformedAcceptance Criteria (Implicitly met by standard)Reported Device Performance (as stated in document)
    Static Axial Compression Bending (ASTM F1717)Acceptable (as per ASTM F1717)Found to be acceptable
    Static Torsion (ASTM F1717)Acceptable (as per ASTM F1717)Found to be acceptable
    Dynamic Axial Compression Bending (ASTM F1717)Acceptable (as per ASTM F1717)Found to be acceptable
    Corrosion Testing (ASTM F2129)Acceptable (as per ASTM F2129)Found to be acceptable
    Auger Emission Spectroscopy (AES) analysis of nitinol clipAcceptable (as per internal protocol/standard)Found to be acceptable
    Screw Push-out Testing (per protocol)Acceptable (as per internal protocol)Found to be acceptable

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

    • Sample Size: Not specified. For mechanical testing of medical devices, sample sizes are typically determined by statistical methods for engineering testing (e.g., to achieve a certain confidence level or power for a material property) but are usually much smaller than clinical study sample sizes.
    • Data Provenance: Not applicable in the context of this device's performance testing. These are laboratory-based mechanical and material tests.

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

    • Not Applicable. This is a mechanical device, and "ground truth" as it relates to expert consensus for diagnostic performance does not apply. The "truth" is determined by standardized laboratory measurements.

    4. Adjudication method

    • Not Applicable.

    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done

    • No. This is a mechanical device, not a diagnostic tool requiring human interpretation.

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

    • Not Applicable. This is a physical medical device, not an algorithm.

    7. The type of ground truth used

    • N/A (for "ground truth" in diagnostic terms). The "truth" is established by adherence to specified ASTM standards and internal engineering protocols for mechanical and material properties. For example, for corrosion testing, the "ground truth" is that the device passes or fails the specified electrochemical impedance parameters defined by ASTM F2129.

    8. The sample size for the training set

    • Not Applicable. This is a physical medical device. There is no "training set" in the context of machine learning or algorithms. Its design and manufacturing process are validated, but not "trained."

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

    • Not Applicable.

    AI/ML Overview

    The document provided is a 510(k) premarket notification decision letter from the FDA to Renovis Surgical Technologies, Inc., regarding their "Renovis Surgical Hip Replacement System." This document primarily focuses on the regulatory clearance of a medical device and describes its intended use, design, and comparison to a predicate device.

    It does not contain information about acceptance criteria or a study proving the device meets those criteria in the context of an AI/ML algorithm's performance. The document is for a traditional surgical implant (hip replacement system), not a software device or an AI/ML-driven diagnostic or therapeutic tool.

    Therefore, I cannot extract the requested information based on the provided text. The questions posed in your prompt (e.g., sample size for test set, data provenance, number of experts for ground truth, adjudication method, MRMC studies, standalone performance, training set size, ground truth for training set) are relevant to the evaluation of AI/ML-based medical devices, which this document does not cover.

    The "Non-clinical Testing" section (G) refers to bench testing of the femoral stems according to ISO 7206-4 and coating characterization, but this directly relates to the mechanical performance and material properties of the physical implant, not the diagnostic accuracy or performance of a software algorithm.

Two radiographic markers made of tantalum per ASTM F650 are included in the PLIF and OLIF PEEK implants, and three radiographic markers made of tantalum per ASTM F560 are included in the TLIF PEEK implant to allow radiographic visualization.

    AI/ML Overview

    This document is a 510(k) summary for the Renovis S141 Lumbar Interbody Cage System. It primarily focuses on demonstrating substantial equivalence to predicate devices based on indications for use, materials, dimensions, function, and mechanical testing. It is not a study that proves a device meets acceptance criteria in the sense of a clinical trial or an AI/software performance study.

    Therefore, many of the requested items related to AI/software performance, ground truth, expert adjudication, and clinical study details are not applicable or cannot be extracted from this type of regulatory submission. This document describes mechanical performance testing against established standards, not a clinical study with human subjects, AI algorithms, or expert readers.

    Here's a breakdown of what can be extracted and what cannot:

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

    Acceptance CriteriaReported Device Performance
    Testing Standards:The Renovis S141 Lumbar Interbody Cage System was tested according to:
    ASTM F2077- Static and dynamic axial compression
    ASTM F2267- Subsidence
    - Expulsion
    Outcome:Test results demonstrate that the Renovis S141 Lumbar Interbody Cage System is substantially equivalent to the predicate devices.

    Note: The document states the device was tested to these standards and found substantially equivalent, but it does not provide specific numerical acceptance criteria or performance metrics for each test (e.g., "subsidence must be less than X mm, and observed subsidence was Y mm"). It only states the overall conclusion of substantial equivalence.

    Regarding the other requested information:

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

      • Not Applicable / Not Provided. This document describes mechanical testing of physical devices, not a study involving human patient data or software/AI. The "test set" here refers to the physical samples of the interbody cage system tested mechanically. The sample size for these mechanical tests is not specified, nor is data provenance in the context of clinical/patient data.
    • 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)

      • Not Applicable. Ground truth in the context of expert review applies to diagnostic devices or AI, not mechanical orthopedic implants. The "ground truth" for mechanical testing is defined by the physical properties and performance characteristics measured against engineering standards.
    • 4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

      • Not Applicable. Adjudication is relevant for expert review or clinical event assessment, not for mechanical testing of physical devices.
    • 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 mechanical device, not an AI or diagnostic imaging device. Therefore, no MRMC study, human readers, or AI assistance is involved.
    • 6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

      • Not Applicable. This is a physical medical device (lumbar interbody cage system), not an algorithm or software. No standalone algorithm performance was assessed.
    • 7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

      • Not Applicable. For mechanical testing, the "ground truth" is defined by the established engineering standards (ASTM F2077 and ASTM F2267) and the measured physical performance (axial compression, subsidence, expulsion).
    • 8. The sample size for the training set

      • Not Applicable. This document does not describe a machine learning algorithm, so there is no "training set."
    • 9. How the ground truth for the training set was established

      • Not Applicable. As there is no training set for a machine learning algorithm, this question is not relevant.
