    APERTO Lucent MRI System

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

    The APERTO Lucent System is an imaging device, and is intended to provide the physician with physiological and clinical information, obtained non invasively and without the use of ionizing radiation. The MR system produces transverse, coronal, sagittal, oblique, and curved cross sectional images that display the internal structure of the head, body, or extremities. The images produced by the MR system reflect the spatial distribution of protons (hydrogen nuclei) exhibiting magnetic resonance. The NMR properties that determine the image appearance are proton density, spin lattice relaxation time (T1), spin spin relaxation time (T2) and flow. When interpreted by a trained physician, these images provide information that can be useful in diagnosis determination.

    Device Description

    The APERTO Lucent is a modification of the AIRIS Elite MRI System. The APERTO Lucent has been revised to increase the clinical utility as compared to the AIRIS Elite Magnetic Resonance imaging system. Magnetic Resonance imaging (MRI) is based on the fact that certain atomic nuclei have electromagnetic properties that cause them to act as small spinning bar magnets. The most ubiquitous of these nuclei is hydrogen, which makes it the primary nuclei currently used in magnetic resonance imaging. When placed in a static magnetic field, these nuclei assume a net orientation or alignment with the magnetic field, referred to as a net magnetization vector. The introduction of a short burst of radiofrequency (RF) excitation of a wavelength specific to the magnetic field strength and to the atomic nuclei under consideration can cause a re-orientation of the net magnetization vector. When the RF excitation is removed, the protons relax and return to their original vector. The rate of relaxation is exponential and varies with the character of the proton and its adjacent molecular environment. This re-orientation process is characterized by two exponential relaxation times, called T1 and T2. A RF emission or echo that can be measured accompanies these relaxation events. The emissions are used to develop a representation of the relaxation events in a three dimensional matrix. Spatial localization is encoded into the echoes by varying the RF excitation, applying appropriate magnetic field gradients in the x, y, and z directions, and changing the direction and strength of these gradients. Images depicting the spatial distribution of the NMR characteristics can be reconstructed by using image processing techniques similar to those used in computed tomography.

    AI/ML Overview

    The provided text describes the FUJIFILM Healthcare Corporation's APERTO Lucent MRI System (K233629) and its substantial equivalence to a predicate device, the AIRIS Elite V4.9 MRI system (K032232).

    The document does not describe specific acceptance criteria in terms of numerical thresholds for device performance (e.g., accuracy, sensitivity, specificity). Instead, it focuses on demonstrating substantial equivalence through a comparison of technological characteristics and performance evaluations.

    Here's the information extracted from the document:

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

    As mentioned, explicit numerical acceptance criteria for performance metrics are not provided. The performance evaluation focuses on demonstrating that the new features and coils perform as intended and produce acceptable image quality for clinical use.

    Acceptance Criteria (Inferred from Rationale Analysis)Reported Device Performance (Summary from Performance Evaluation)
    New features perform as intended for diagnostic use.Test data confirmed that new features perform as intended for diagnostic use.
    Clinical images from new features and coils have acceptable image quality for clinical use.A radiologist validated that the clinical images have acceptable image quality for clinical use.

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

    • Test set sample size: Not explicitly stated. The document refers to "clinical image examples" for new features and coils.
    • Data provenance: Not explicitly stated (e.g., country of origin). The study involved "clinical image examples" and validation by a radiologist. It is likely prospective, as it involves evaluating new features and coils.

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

    • Number of experts: One radiologist.
    • Qualifications of experts: "A radiologist." No further details on years of experience or sub-specialty are provided.

    4. Adjudication method for the test set

    • Adjudication method: Not applicable/None mentioned. The document states a single radiologist validated the clinical images for acceptable image quality. There is no indication of multiple reviewers or an adjudication process.

    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. This submission is for an MRI system, not an AI-assisted diagnostic device. The document does not describe any AI component or human-in-the-loop performance evaluation.

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

    • Standalone performance: Not applicable. This is for an MRI system, not an algorithm.

    7. The type of ground truth used

    • Ground truth: Clinical images were validated for "acceptable image quality for clinical use" by a radiologist. This can be considered a form of expert assessment/consensus (from a single expert in this case) on image quality rather than a definitive "ground truth" for specific diagnoses, as the purpose was to evaluate system functionality and image quality.

    8. The sample size for the training set

    • Training set sample size: Not applicable. This document describes an MRI system, not an algorithm that undergoes a "training" phase with a dataset. The software development likely involved internal testing and verification, but not in the context of machine learning training data.

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

    • Ground truth for training set: Not applicable (see point 8).

Additionally, it has teeth located on its superior and inferior external surfaces to help keep the device from migrating once placed in its desired location. There are also screw holes located in the implant body. Each screw hole is lined in its internal surface with a titanium ring insert. Screws pass through screw holes of the implant body and affix to bone to help prevent implant migration. When fully seated, the screw head rests on the titanium insert of the screw hole.

    The Lucent device is an interbody fusion device for use in lumbar spine surgery. Because PEEK is translucent, tantalum pins are placed in various locations of the PEEK device to serve as markers for radiographic visualization of the device orientation. The Lucent devices are of various shapes, heights, width, length and lordosis to suit patient anatomy.

    The Zeus Interbody Fusion Devices are comprised of implants designed to treat the cervical and lumbar spine. The implants are available in a range of sizes and shapes to accommodate variations in surgical approach and patient anatomy. Each cage has a hollow center to allow placement of autograft. Ridges on the superior and inferior surfaces of the device help to grip the endplates and prevent expulsion.

    AI/ML Overview

    This document is a 510(k) Premarket Notification from the FDA regarding several spinal intervertebral body fusion devices manufactured by Spinal Elements, Inc. The document states that the devices are substantially equivalent to previously marketed predicate devices and therefore do not require a premarket approval application.

    Critically, this document is a regulatory approval notice based on the substantial equivalence principle, not a study evaluating the performance of an AI/ML powered medical device. It explicitly states under "Performance Data" that: "No changes were made to the existing devices nor were any new components were added to the systems. Therefore, no additional testing was required or performed."

    As such, this document does not contain the information required to answer the prompt regarding acceptance criteria and a study that proves the device meets those criteria for an AI/ML powered medical device. The device described (intervertebral body fusion devices) is a physical implant, not a software-based AI/ML product.

    Therefore, I cannot provide the requested information based on this document.

    AI/ML Overview

    The provided text is a 510(k) premarket notification summary for the Lucent : IPL device. This document focuses on demonstrating substantial equivalence to predicate devices rather than proving the device meets specific acceptance criteria through a clinical study.

    Therefore, many of the requested elements for describing "acceptance criteria and the study that proves the device meets the acceptance criteria" are explicitly stated as not applicable or not required in this type of submission.

    Here's a breakdown based on the provided document:


    Acceptance Criteria and Device Performance for Lucent : IPL

    The device, Lucent : IPL, did not undergo a de novo clinical study with specific acceptance criteria in the typical sense for this 510(k) submission. Instead, its performance and safety are established by demonstrating substantial equivalence to legally marketed predicate devices. The "acceptance criteria" here are implicitly linked to showing that its technical specifications and indications for use fall within the established range or scope of the predicates, and that any differences do not raise new questions of safety or effectiveness.

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

    Since no specific performance metrics with predefined acceptance criteria from a de novo study are presented, the "acceptance criteria" are the ranges and types of indications provided by the predicate devices. The "reported device performance" is the Lucent : IPL's own specifications.

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

    • Sample Size: Not applicable. A human clinical study (test set) was explicitly not required for this 510(k) submission, as stated in the document ("Results of Clinical Study: A human clinical study was not required as the device is substantially equivalent to the predicate devices.").
    • Data Provenance: Not applicable, as no clinical study was performed.

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

    • Not applicable, as no clinical study was performed and no "ground truth" for a test set was established.

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

    • Not applicable, as no clinical study was performed and no "ground truth" for a test set was established.

    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 IPL system, not an AI-assisted diagnostic tool.

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

    • Not applicable. This is a medical device for treatment, not an AI algorithm.

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

    • Not applicable. The basis for clearance is substantial equivalence to existing legally marketed predicate devices, meaning that the device's technical specifications and indications for use are similar enough not to raise new safety or effectiveness concerns. The "ground truth" in this context is the FDA's prior clearance of the predicate devices based on their established safety and effectiveness.

    8. The sample size for the training set:

    • Not applicable. This refers to AI/ML development, which is not relevant to this type of device and submission.

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

    • Not applicable. This refers to AI/ML development, which is not relevant to this type of device and submission.

    Summary of the Study Proving Device Meets Acceptance Criteria:

    The "study" proving the Lucent : IPL meets acceptance criteria is the 510(k) premarket notification review process, which involved:

    • Comparison to Predicate Devices: The submission meticulously compares the Lucent : IPL's technical specifications (wavelength, intended use, indications for use, pulse width, energy density, spot size) to two predicate devices:
      • Alma Harmony XL Multi-Application Platform (K072564)
      • Lumenis M22 System (K142860)
    • Performance Testing (Non-Clinical): The document states that the following performance data was provided:
      • ES60601-1:2005/(R)2012 and A1:2012 Test for Medical Electrical equipment (General Requirements for basic safety and essential performance)
      • IEC 60601-1-2 Edition 4.0 2014-02 Test for Medical Equipment (General Requirements for basic safety and essential performance: electromagnetic compatibility)
      • IEC 60601-2-57 Edition 1.0 2011-01 (Particular requirements for the basic safety and essential performance of non-laser light source equipment intended for therapeutic, diagnostic, monitoring and cosmetic/aesthetic use)

    The conclusion, explicitly stated in the document, is: "The Lucent : IPL's intended use, indications for use and technical specifications are substantially equivalent to the Harmony XL Multi-Application Platform and the M22 System." This "substantial equivalence" is the "proof" accepted by the FDA for clearance in this case, rather than a de novo clinical study with specific performance metrics.

    Not applicable. This device is not an AI-assisted diagnostic tool.

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

    Not applicable. This is a physical medical device.

    7. The type of ground truth used

    The ground truth for this device's performance is based on engineering specifications, material science, sterility standards, and regulatory requirements (e.g., MRI compatibility standards). For example, "MR-Compatibility" is verified against established standards for how metallic or non-metallic objects interact with MRI fields. "Static load" is verified against a specified weight with a safety factor.

    8. The sample size for the training set

    Not applicable. This is a physical medical device and does not involve AI/machine learning training sets.

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

    Not applicable. As there is no training set for an AI algorithm, no ground truth needs to be established for it.

This 510(k) pertains to line additions to an already cleared device, and the submission primarily focuses on demonstrating substantial equivalence to predicate devices, rather than presenting new performance data against specific acceptance criteria.

    The "Performance Data" section explicitly states: "No clinical testing was found to be necessary. Given the type of changes made to the Lucent device, no additional non-clinical testing was required or performed."

    Therefore, I cannot generate a table of acceptance criteria and reported device performance from this document.

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

    As stated above, no new performance data or clinical testing was conducted for this 510(k) submission. The device's substantial equivalence is based on its similarity to previously cleared devices. Therefore, there is no test set sample size or data provenance to report from this document.

    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):

    Since no new performance data or clinical testing was performed, there was no test set for which ground truth needed to be established by experts.

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

    Not applicable, as no test set was used for new performance evaluation.

    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 intervertebral body fusion device (a physical implant), not an AI-powered diagnostic or assistive tool. Therefore, an MRMC study involving human readers and AI assistance is irrelevant to this submission.

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

    Not applicable. This is not an algorithm or AI device.

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

    Not applicable, as no new performance validation using a specific ground truth was conducted. The ground for substantial equivalence relies on comparison of design, materials, and indications for use with predicate devices.

    8. The sample size for the training set:

    Not applicable. This is a physical medical device, not an AI model requiring a training set.

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

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

    Summary of Device Acceptance and Study proving criteria:

    The document describes the device, Lucent®, as an intervertebral body fusion device. This 510(k) submission is for line additions to an already cleared device. The primary method of demonstrating acceptance and meeting criteria is through substantial equivalence to legally marketed predicate devices.

    The study that "proves" the device meets acceptance criteria, in this context, is the comparison to predicate devices. The submission argues that:

    • The subject device is identical in indications for use, manufacturing method, raw material and operating principles to the predicate devices cleared in K122967 and K150061.
    • It has equivalent technological characteristics to its predicates in areas including labeling/indications for use, general design features, function, material, manufacturing process, and instrumentation.

    Therefore, the "proof" is based on the argument that because the device is sufficiently similar to devices already found safe and effective, no new performance studies are required.
