    OTIS-C-PLUS, NEOTIS PLATE, SCREW 06.5

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    NEOTIS Plate is intended to be used in conjunction with bone screws to provide fixation following Proximal Tibial Opening wedge osteotomies.

    Device Description

    The NEOTIS plate is designed for medial approach High Tibial Osteotomy stabilization. Anatomically shaped, thin and short, the NEOTIS plate enables minimally invasive surgery. The changes brought by the NEOTIS plate are as follows (vs. OTIS-C Plus plate):

    • The proximal temporary screw is replaced with a pin that offers a simpler and faster placement of the plate. The area of the cortical bone drilled through the process is also reduced.
    • The distal temporary screw is replaced with an AO screw in order to maintain compression. The compression will be maintained by the 4 permanent 6.5 mm screws (OTIS screws).
    AI/ML Overview

    The provided documentation describes a traditional 510(k) submission for the NEOTIS Plate and Screws, a medical device for bone fixation. Here's a breakdown of the acceptance criteria and the study information as extracted from the text:

    1. Table of Acceptance Criteria and Reported Device Performance

    Acceptance Criteria TypeAcceptance CriteriaReported Device Performance
    Mechanical PropertiesNot explicitly stated as acceptance criteria, but implied to be equivalent to the predicate device."The mechanical properties are the same as for the previous OTIS-C Plus"
    Placement Process (Temporary Screw/Pin)Improved ease and speed of placement, reduced drilled cortical bone area."The proximal temporary screw is replaced with a pin that offers a simpler and faster placement of the plate. The area of the cortical bone drilled through the process is also reduced."
    Compression Maintenance (Distal Screw)Compression to be maintained."The distal temporary screw is replaced with an AO screw in order to maintain compression. The compression will be maintained by the 4 permanent 6.5 mm screws (OTIS screws)."
    Substantial EquivalenceDemonstrate that the modified NEOTIS plate is as safe, as effective, and performs as safely and effectively as its predicate device."Verification and validation tests demonstrate that modified the NEOTIS plate is as safe, as effective, and performs as safely and effectively as its predicate device."
    Confirmation of Compression (Cadaver Study)Not explicitly stated as an acceptance criterion, but the cadaver study's purpose was to confirm this."Non-clinical performance testing includes a cadaver study that confirms the level of compression induced during the placement of the plate."

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

    • Sample Size for Test Set: Not explicitly stated. The document mentions a "cadaver study" but does not provide details on the number of cadavers or specimens used.
    • Data Provenance: The cadaver study is implied to be laboratory-based (non-clinical performance testing). The document does not specify the country of origin for the cadaver data, nor does it explicitly state if it was retrospective or prospective, though "non-clinical performance testing" typically implies prospective experimental testing.

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

    • The documentation does not provide information about experts establishing ground truth for the cadaver study. The study appears to be a mechanical performance test rather than one requiring clinical interpretation by experts to establish ground truth.

    4. Adjudication Method for the Test Set

    • Not applicable/Not mentioned. The study described is a non-clinical performance test, not a study involving human interpretation with adjudication.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

    • No, an MRMC comparative effectiveness study was not done. The device is hardware (plate and screws), not an AI algorithm or diagnostic tool that would typically undergo an MRMC study.

    6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

    • No, this is not applicable. The device is a physical medical implant, not an algorithm.

    7. The Type of Ground Truth Used

    • For the cadaver study, the "ground truth" was the level of compression induced by the device during placement. This is a direct physical measurement/observation in a controlled experimental setting, not expert consensus, pathology, or outcomes data in the clinical sense.

    8. The Sample Size for the Training Set

    • Not applicable. The 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. The device is not an AI/ML algorithm.

    C-PLUS

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    When used as a cervical intervertebral body fusion device (C-Plus), the Interbody Fusion (IBF) / Vertebral Body Replacement (VBR) System ("IBF/VBR System") is indicated for intervertebral body fusion of the spine in skeletally mature patients. Cervical IBFs are intended for use at one level in the cervical spine, from the C2-C3 disc to the C7-T1 disc, for the treatment of cervical disc disease (defined as neck pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies). The cervical device is to be used in patients who have had six weeks of non-operative treatment. IBFs are designed for use with autogenous bone graft to facilitate fusion. IBFs are intended to be used with supplemental spinal fixation cleared for the implanted level, such as Streamline OCT, SlimFuse, Cequence, PAC, Aspect Systems.

    When used as a lumbar intervertebral body fusion device (Rotate, Bullet-Tip, T-Plus, Contact, CrossFuse, CrossFuse II), the Interbody Fusion (IBF) / Vertebral Body Replacement (VBR) System ("IBF/VBR System") is indicated for intervertebral body fusion of the spine in skeletally mature patients. Lumbar IBFs are intended for use at either one level or two contiguous levels in the lumbar spine, from the L2 to S1, for the treatment of degenerative disc disease (DDD) with up to Grade 1 spondylolisthesis. DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. Lumbar IBFs are to be used in patients who have had six months of non-operative treatment. IBFs are designed for use with autogenous bone graft to facilitate fusion. IBFs are intended to be used with supplemental spinal fixation cleared for the implanted level, such as Quantum, Streamline TL, Contact ALP, or Streamline MIS Systems.

    When used as a vertebral body replacement (VBR) device (C-Plus, Rotate. Bullet-Tip, T-Plus, Contact, CrossFuse, CrossFuse II), the Interbody Fusion (IBF) / Vertebral Body Replacement (VBR) System ("IBF/VBR System") is intended for use in the thoracolumbar spine (T1-L5) for partial replacement (i.e., partial vertebrectomy) of a diseased vertebral body resected or excised for the treatment of turnors in order to achieve anterior decompression of the spinal cord and neural tissues, and to restore the height of a collapsed vertebral body. VBRs are also indicated for treating fractures of the thoracic and lumbar spine. VBRs are designed to restore the biomechanical integrity of the anterior, middle and posterior spinal column, even in the absence of fusion for a prolonged period of time. The system must be used with the Quantum Spinal Fixation System or supplemental internal fixation systems cleared for the conditions listed above (i.e., tumor or trauma of T1-L5). Additionally, the VBR device is intended to be used with bone graft.

    Device Description

    The Interbody Fusion (IBF) / Vertebral Body Replacement (VBR) System consists of a variety of different footprints and heights which enable the surgeon to choose the implant best suited to an individual's pathology and anatomical condition. Supplemental anterior and/or posterior fixation is intended for use with the device to ensure stability of the spine and adequate compression of the implant. The IBF/VBR implants may be implanted via a variety or open or minimally invasive approaches, including anterior, lateral, posterior and oblique. The components are manufactured from a radiolucent polymer (PEEK Optima®) in order to allow radiographic imaging inside the implant to evaluate fusion status. The purpose of this submission is a line extension to add an additional design to the currently available C-Plus implants. The subject implants are for Cervical Intervertebral Body Fusion only. Class I (exempt) orthopedic manual surgical instruments are also available.

    AI/ML Overview

    The provided text describes a 510(k) Summary for an Interbody Fusion (IBF) / Vertebral Body Replacement (VBR) System.

    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for mechanical testing is established by physical measurement against ASTM standards, not expert clinical interpretation.
    3. Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable.
    4. 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 device (implant) submission, not an AI/imaging software submission.
    5. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable. This is a medical device (implant) submission, not an AI/imaging software submission.
    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): The ground truth for the mechanical performance testing is established by ASTM standards and measurements of physical properties like compression, torsion, subsidence, and expulsion.
    7. The sample size for the training set: Not applicable. There is no "training set" in the context of mechanical bench testing for a physical implant.
    8. How the ground truth for the training set was established: Not applicable.

    Summary of the Study:

    The study conducted was a pre-clinical mechanical bench testing of the Interbody Fusion (IBF) / Vertebral Body Replacement (VBR) System. This involved performing various tests to assess the device's static compression, static torsion, static subsidence, and static expulsion characteristics. The results of these tests were compared against established ASTM standards (F2077, F2267) and a draft standard (Z8423Z), as well as against a legally marketed predicate device. The conclusion was that the device's mechanical strength is substantially equivalent to the predicate and sufficient for its intended use.

    Intended Use

    OTIS-C Plus is intended to be used in conjunction with bone screws to provide fixation following Proximal Tibial Opening wedge osteotomies

    Device Description

    The OTIS-C Plus plate is designed for the stabilization of High Tibial Osteotomy with a medial approach. Anatomically shaped, thin and short, the OTIS-C Plus plate enables mini-invasive surgery. Its locking system provides immediate compression of the graft as well as stable fixation, thus allowing early weight-bearing. The design of the self-tapping OTIS-C Plus screws (unmodified) allows easy and reliable one step locking, without counter-nut, in a simple and concise approach. With its range of twelve screws lengths, fixation can be either mono or bi-cortical, upon the choice of the surgeon.

    AI/ML Overview

    The provided document is a 510(k) summary for a medical device (OTIS-C Plus) and does not contain information about a study with acceptance criteria often seen for AI/ML-driven devices. Instead, it describes non-clinical performance testing for a traditional metallic bone fixation appliance.

    Therefore, many of the requested categories (e.g., sample size for test set, number of experts, adjudication method, MRMC study, training set information, ground truth types) are not applicable to the information provided in this document excerpt.

    However, I can extract the relevant information regarding the performance claims and the type of testing performed.

    1. Table of acceptance criteria and the reported device performance

    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 is not applicable. The ground truth for mechanical testing is derived from engineering standards and physical measurements, not expert consensus.

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

    This is not applicable. Adjudication methods are typically used for clinical study data, not for non-clinical mechanical 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

    This is not applicable. This document describes a traditional medical device (bone plate and screws), not an AI/ML-driven diagnostic or assistive technology.

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

    This is not applicable. This describes a physical medical device.

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

    For the non-clinical performance testing, the "ground truth" (or reference standard) would be established by engineering standards, material properties, and validated testing methodologies (e.g., ISO, ASTM standards for material testing) to measure the mechanical properties of the device components.

    AI/ML Overview

    The provided text describes the 510(k) summary for the MAGLIFE C/MAGLIFE C Plus patient monitor. It focuses on demonstrating substantial equivalence to predicate devices through non-clinical testing. Here's a breakdown of the requested information:

    Acceptance Criteria and Reported Device Performance

    The device is evaluated based on its ability to function without degradation in performance within an MRI environment and to not interfere with the MRI unit. The reported performance suggests it meets these criteria.

    Acceptance CriteriaReported Device Performance
    1. Maximum magnetic field strength the device can withstand without degradation of performance.Tests were conducted "to determine the maximum field strength that Maglife C can withstand without degradation of performance." (Specific measurement of maximum field strength is not provided, only that it was tested and met the criteria).
    2. Sufficiency of non-ferrous material to prevent movement due to magnetic attraction.Tests were conducted "to verify that the amount of ferrous material in the Maglife C is sufficiently small so that movement of the unit due to magnetic attraction is not possible." (No specific measurement of ferrous material or force is provided, only that it met the criteria).
    3. Effect on the homogeneity of the magnetic field inside the magnet bore without causing visible differences in images. (Tested with a 1.5 Tesla MR unit)."These tests, using a 1.5 Tesla MR unit, showed that the Maglife could be placed as close as 60 cm from the front of the opening from the magnet without causing any visible difference in the images."

    Since this is a 510(k) submission for a patient monitor and the studies are non-clinical tests, much of the requested information regarding clinical studies, ground truth, and expert evaluation is not applicable or explicitly stated in this document.

    Here's an attempt to answer the remaining questions based on the provided text, indicating "Not Applicable" or "Not Stated" where the information is missing:

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

    • Sample Size: Not applicable as these were non-clinical engineering and bench tests, not patient data tests. The "sample" would be the device itself.
    • Data Provenance: Not applicable. The tests were presumably conducted internally by SCHILLER MEDICAL or a contracted testing facility.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

    • Number of Experts: Not applicable. Ground truth for these non-clinical tests would have been established by engineering standards and direct physical measurements/observations by testing personnel, not medical experts.
    • Qualifications of Experts: Not applicable.

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

    • Adjudication Method: Not applicable. This refers to expert review of clinical cases. For non-clinical tests, compliance is typically determined by meeting predefined technical specifications or 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

    • MRMC Study: No, an MRMC study was not done. This type of study involves human readers interpreting cases, often with AI assistance, which is not relevant for a patient monitor's non-clinical validation.
    • Effect Size: Not applicable.

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

    • Standalone Performance: While the "device" itself functions standalone in terms of its monitoring capabilities, the testing described is primarily about its physical and electromagnetic compatibility within an MRI environment, not an AI algorithm's standalone diagnostic performance. No "algorithm only" performance study in the context of AI is described.

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

    • Type of Ground Truth: For the non-clinical tests described, the "ground truth" was established by engineering standards, physical laws, and direct measurement (e.g., whether the device moved, whether images showed visible differences, ability to function at a certain field strength). This is not equivalent to clinical ground truth derived from pathology or expert consensus.

    8. The sample size for the training set

    • Sample Size for Training Set: Not applicable. This device is a patient monitor, and there is no mention of an AI/machine learning component that would require a "training set" in the context of the 510(k) summary provided.

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

    • Ground Truth for Training Set: Not applicable, as there is no mention of a training set.

    Device Name :

    DADE THROMBOPLASTIN C PLUS

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    Dried Rabbit Brain Thromboplastin with Calcium. For use in prothrombin time (PT) determinations and prothrombin time based assays.

    Device Description

    Dade® Thromboplastin C Plus is a lyophilized preparation of dried rabbit brain with calcium and stabilizers. The reagent initiates clotting via the extrinsic common pathway in a global screening test, the prothrombin time (PT). The obtained clotting time detects single or combined deficiencies of the extrinsic coagulation system indicative of hereditary and acquired coagulation disorders, is a sensitive monitoring test for oral anticoagulation therapy and an assay for specific coagulation factors.

    AI/ML Overview

    Here's a summary of the acceptance criteria and study details for the Dade® Thromboplastin C Plus, based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria are implied by the "Max. Error Criteria %CV" column in the precision study. The device performance (Total %CV) is compared against these maximum allowable values. For the method comparison studies, the "Coefficient of Correlation (r)" values suggest that a strong positive correlation (closer to 1) is desired, though a specific threshold for acceptance isn't explicitly stated. However, given the context of demonstrating substantial equivalence, values close to 1.0 are indicative of good performance.

    Study Type / MetricAcceptance CriteriaReported Device Performance
    Method Comparison StudiesImplicit: High Coefficient of Correlation (r)Compared against Multifibren™ U on various analyzers:
    • BCTTM/BCTTM: r = 0.951
    • BCSTM/BCTTM: r = 0.935
    • Sysmex® CA-1500/BCT: r = 0.965
    • Sysmex® CA-6000/BCT: r = 0.943
    • Sysmex® CA-500/BCT: r = 0.975 |
      | Precision Study (Derived Fibrinogen) | %CV should be ≤ Max. Error Criteria %CV (10%) | Control Plasma N (CPN): Total %CV = 5.4% (vs. 10% criteria)
      Control Plasma P (CPP): Total %CV = 1.1% (no criteria specified for this low-level control, but low is good)
      Normal Plasma Pool (NPP): Total %CV = 4.6% (vs. 10% criteria)
      Pathological Plasma Pool (PPP): Total %CV = 4.5% (vs. 10% criteria) |

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

    • Test Set Sample Size: For the method comparison studies, the sample sizes ranged from 103 to 176 specimens, depending on the analyzer used. For the precision study, each control/plasma pool had 40 replicates (n=40).
    • Data Provenance: Not specified in the provided text (e.g., country of origin, retrospective or prospective).

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

    • This information is not applicable as the device is an in vitro diagnostic (IVD) for laboratory testing, not an imaging or diagnostic device requiring expert interpretation for ground truth. The "ground truth" for these studies would be the actual fibrinogen concentration or prothrombin time as measured by an established reference method (the predicate device, Multifibren™ U, in the comparison study).

    4. Adjudication Method for the Test Set

    • Not applicable. As an IVD, an adjudication method by human experts is not typically used for establishing ground truth for chemical/coagulation assays. Ground truth is based on the reference method's results.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    • Not applicable. This device is an IVD for prothrombin time and fibrinogen determination, not an AI-assisted diagnostic tool for human readers.

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

    • Yes, a standalone performance study was done. The studies presented (method comparison and precision studies) demonstrate the performance of the Dade® Thromboplastin C Plus reagent in conjunction with automated coagulation analyzers. These are essentially standalone performance evaluations of the reagent and analyzer system.

    7. The Type of Ground Truth Used

    • For Method Comparison Studies: The ground truth was essentially the measurements obtained using the predicate device, Multifibren™ U. The goal was to show strong correlation and agreement between the new device and the predicate.
    • For Precision Studies: The ground truth for calculating variability (%CV) would be the true/reference value of the control plasmas, which are characterized for their expected fibrinogen levels.

    8. The Sample Size for the Training Set

    • Not applicable. The provided text describes performance validation studies for an IVD reagent. There is no indication of a machine learning model or "training set" in the context of this device's development or regulatory submission.

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

    • Not applicable. (See point 8.)

    Device Name :

    . - HDL/LDL-C-PLUS

    AI/MLSaMDIVD (In Vitro Diagnostic)TherapeuticDiagnosticis PCCP AuthorizedThirdpartyExpeditedreview
    Intended Use

    For the calibration of test systems for the measurement of HDL and LDL Cholesterol in human serum or plasma.

    Device Description

    The Boehringer Mannheim c.f.a.s. - HDL/LDL-C plus calibrator consists of lyophilized human serum with added HDL-Cholesterol and LDL-Cholesterol.

    AI/ML Overview

    The provided text is a 510(k) Summary for a medical device, specifically a calibrator used in diagnostic tests for HDL and LDL cholesterol. This type of document is for regulatory clearance and does not typically include detailed study results, acceptance criteria, or performance metrics in the way a clinical study report would.

    Therefore, the document does not contain the information requested in points 1-9 regarding acceptance criteria and a study proving the device meets those criteria.

    The 510(k) Summary focuses on demonstrating "substantial equivalence" to a predicate device, not on presenting novel performance data from a clinical trial with acceptance criteria. It states:

    • "The Boehringer Mannheim Direct LDL-Cholesterol test is substantially equivalent to other products in commercial distribution intended for similar use."
    • "The intended use of this BM calibrator and the predicate devices is the same..."

    For this type of device (a calibrator), the "performance" demonstrated for regulatory clearance would likely involve analytical studies confirming its accuracy, precision, and stability as a calibrator, ensuring it produces expected values when used with compatible test systems. However, these specific details are not present in the provided text.
