    AI/ML Overview

    This FDA 510(k) clearance letter for the Stellar M22 device does not contain any information about acceptance criteria or a study proving the device meets said criteria for an AI/algorithm-driven component.

    The document explicitly states:

    • "No new clinical validation was required to support the Stellar M22 as the clinical validation of the Lumenis predicate device also applies to the subject device." This indicates that no new clinical study was performed for this specific submission to demonstrate performance.
    • The modifications described are "mainly due to the addition of new Hardware to serve marketing, business and serviced purposes," and "to maintain Lumenis' high-level service capabilities to the professional end-users and their patients, through establishment of a secure transmission of technical information to the cloud for further analysis and rapid problem-solving." This strongly suggests the changes are related to connectivity and serviceability, not a new AI/algorithm feature requiring performance validation.

    Therefore, I cannot provide the requested information from the provided text. The document describes a device modification for an existing system (Stellar M22) and asserts substantial equivalence to its predicate based on the fact that the changes are primarily hardware upgrades for service and marketing, and the clinical validation of the predicate device is considered applicable.

    There is no mention of any AI component, performance criteria for such a component, or a study validating its performance in this submission.

    AI/ML Overview

    The provided document is a 510(k) Summary for the Bausch + Lomb Stellaris Elite™ vision enhancement system. It primarily focuses on demonstrating substantial equivalence to a predicate device after software and hardware updates, rather than presenting a study proving a device meets specific acceptance criteria for performance.

    Therefore, many of the requested categories cannot be fully addressed in the traditional sense of a clinical or performance study aimed at defining and meeting specific analytical or clinical performance metrics. The document describes how substantial equivalence was demonstrated, which involves various types of testing, but not a study designed to prove new performance claims against defined acceptance criteria.

    Below is the information extracted and interpreted based on the context of this 510(k) submission, highlighting what is available and what is not.


    Acceptance Criteria and Device Performance Study for K232084

    This 510(k) submission (K232084) is for updates to the Bausch + Lomb Stellaris Elite™ vision enhancement system, not for a new device making novel performance claims. The primary goal is to demonstrate "substantial equivalence" to a legally marketed predicate device (K170052 Stellaris Elite™ vision enhancement system) after changes to the User Interface Computer System on Module (SOM) and an update to the operating system from Windows XP to Windows 10. Consequently, the "acceptance criteria" and "device performance" are framed in terms of meeting regulatory standards and maintaining performance equivalent to the predicate device, rather than achieving specific performance thresholds for a novel diagnostic or therapeutic claim.

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

    Given the nature of this 510(k) for system updates, the "acceptance criteria" are regulatory compliance and maintained functionality, rather than specific numerical performance metrics for a clinical task.

    Acceptance Criteria CategoryReported Device Performance / Assessment
    BiocompatibilityNot required; device does not contain direct or indirect patient-contacting materials.
    Electrical SafetyComplies with IEC 60601-1:2020, IEC 60601-1-2:2020, IEC 60601-1-6:2020, IEC 60601-2-2:2017, IEC 60601-2-22:2019, IEC 80601-2-58:2016.

    Acoustical TestingNo specific acoustical testing performed to support this premarket notification for substantial equivalence.
    Overall Functional EquivalenceThe Stellaris Elite™ vision enhancement system features remain the same as the previously approved system and are described as substantially equivalent to the predicate (K170052).
    Maximum vacuumSubject Device: 660 mmHg. Predicate (K170052): 600 mmHg (This is listed as an "incremental improvement" since the predicate of K170052, indicating a specific performance change that was assessed).
    Operating SystemSubject Device: Windows 10. Predicate (K170052): Windows XP. (Functional equivalence demonstrated via software V&V).
    User Interface SOMSubject Device: Congatec. Predicate (K170052): Kontron. (Functional equivalence demonstrated via software V&V and system testing).

    2. Sample size used for the test set and the data provenance
    The document does not specify a "sample size" in the context of a dataset for AI or clinical study. Instead, it refers to "representative units" for hardware testing (electrical safety, EMC) and software verification/validation.

    • Test Set Sample Size: Not applicable in the context of an AI-driven clinical test set. Testing was performed on the device itself and its software.
    • Data Provenance: Not applicable as no patient data or image data was used for a test set. This submission is for hardware/software updates to an ophthalmic surgical system. The standards cited (IEC standards for electrical safety, EMC, software lifecycle) are international regulatory standards.

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
    Not applicable. No "ground truth" for a test set (e.g., diagnostic labels, disease states) was established by experts in this submission, as it's not a diagnostic AI device.

    4. Adjudication method for the test set
    Not applicable. There was no test set requiring expert adjudication.

    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
    Not applicable. This is not an AI-assisted diagnostic or interpretation device that would involve human readers.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
    Not applicable. This device is an ophthalmic surgical system, not a standalone algorithm.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
    Not applicable in the context of a clinical performance study. For software and hardware validation, the "ground truth" would be the functional requirements and established performance specifications of the predicate device and relevant international standards.

    8. The sample size for the training set
    Not applicable. This device does not use a "training set" in the sense of machine learning for interpretation or diagnosis.

    9. How the ground truth for the training set was established
    Not applicable.

    Intended Use

    STELLAR Knee is a stereotaxic system including an intraoperative software as a medical device and surgical instruments. STELLAR Knee is indicated for primary Total Knee Replacement, to assist the surgeon in determining reference alignment axes in relation to anatomical landmarks, in order to position the cutting guide regarding computed mechanical axis. The STELLAR Knee is installed on a Head Mounted Device (HMD) for displaying information to the user intraoperatively. The HMD should not be relied upon solely and should always be used in conjunction with traditional methods.

    Device Description

    The main purpose of the STELLAR Knee is to assist the surgeon during the primary Total Knee Replacement (TKR) intervention. STELLAR Knee includes software and surgical instruments.

    STELLAR Knee uses established surgical navigation techniques to provide information to help track patient bony landmarks in real time to assist the surgeon in determining resection angles and measurements as required in knee replacement surgery. STELLAR Knee allows the surgeon to adjust the cutting plane orientation and the resection level. This includes means for the surgeon to collect anatomical references during the TKR intervention using the surgical instruments. The software locates in a 3D reference frame the instruments which include marker arrays. All collected coordinates are treated by software algorithms to provide the surgeon with the relevant orientation of the tracked cutting quide. STELLAR Knee software is installed on a wearable Head Mounted Device (HMD) which includes an embedded camera and displays intraoperative information to the user. This near-eye display allows the surgeon to look at the HMD screen or the field of view when needed.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for the STELLAR Knee device, which is a stereotaxic system for Total Knee Replacement. However, the document does not contain the detailed acceptance criteria or the study data that proves the device meets those criteria.

    The "Non-clinical performance testing" section briefly mentions that "Bench testing was conducted in order to demonstrate that STELLAR Knee performs according to its requirements and specifications when installed on the Head Mounted Device. In particular, overall system repeatability and accuracy were tested." It also states, "The results demonstrated that the STELLAR Knee performs according to its specifications and functions as intended."

    However, information regarding specific quantitative acceptance criteria (e.g., accuracy thresholds in mm or degrees), the reported device performance against these criteria, sample sizes used, data provenance, ground truth establishment, or any comparative effectiveness studies (MRMC) is not provided in this document.

    Therefore, I cannot fulfill the request to provide a table of acceptance criteria and reported device performance, nor the details of any study that proves the device meets specific acceptance criteria based on the given input. The document focuses on establishing substantial equivalence with a predicate device based on similar indications for use, operating principles, and general performance testing, without detailing the results of those performance tests in a quantitative manner against predefined acceptance criteria.

    AI/ML Overview

    The provided text describes the regulatory clearance for the "Stella" dental implant system. It does not contain information about acceptance criteria or a study demonstrating the device meets performance criteria in the context of AI/ML or diagnostic applications. The document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a predicate device rather than presenting performance data against specific acceptance criteria for a novel AI/ML algorithm.

    Therefore, most of the requested information regarding acceptance criteria, device performance, sample sizes, ground truth, expert opinions, and MRMC studies for an AI/ML device is not present in the provided document.

    However, I can extract the non-clinical testing performed to support the substantial equivalence claim for the Stella dental implant system.

    Here's the relevant information that is available:

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

    This information is not provided in the context of an AI/ML device's diagnostic performance. The document only lists types of non-clinical tests performed for physical characteristics of the dental implant system, and states that the "Stella" has "similar fatigue testing results to the predicate devices in the market" without providing specific acceptance criteria or quantitative results for these comparisons.

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

    Not applicable to this document. The document describes a medical device (dental implant), not a diagnostic algorithm.

    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 to this document.

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

    Not applicable to this document.

    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 to this document.

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

    Not applicable to this document.

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

    Not applicable to this document. The "ground truth" for a physical device like a dental implant would be engineering specifications and material properties, validated through physical testing, not expert consensus on images or pathology.

    8. The sample size for the training set:

    Not applicable to this document, as it does not describe an AI/ML algorithm.

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

    Not applicable to this document.


    Summary of Non-Clinical Testing (as described in the document for the physical device Stella, not an AI/ML component):

    The document highlights the following non-clinical tests performed to support substantial equivalence of the Stella dental implant system:

    Test TypeBasis for Performance Claim
    Fatigue TestPerformed in accordance with ISO 14801. The document states "similar fatigue testing results to the predicate devices in the market" and that "it was confirmed that there was no strength problem through the fatigue test on the fixture diameter 3.7mm." (No specific acceptance criteria or quantitative results are provided in this summary, but the test was done.)
    SLA Surface TreatmentEvaluated under previous 510(k)s (K123155 and K160106) for SHINHUNG MST CO., LTD.'s Luna Dental Implant System.

    AI/ML Overview

    The provided document is a 510(k) Premarket Notification from FONA S.r.l. to the FDA for their Stellaris dental X-ray systems. It primarily focuses on demonstrating substantial equivalence to predicate devices based on technical specifications and adherence to relevant standards.

    The document does NOT describe the acceptance criteria for an AI/ML powered device, nor does it detail a study proving such a device meets acceptance criteria.

    The Stellaris devices are dental X-ray systems (2D and 3D, with and without cephalometric capabilities). The document explicitly states:

    • "The Stellaris 2D, Stellaris 2D Ceph, Stellaris 3D, Stellaris 3D Ceph devices can be used with the OrisWin DG Suite software for image acquisition and database (not part of this submission)..." (page 8)
    • "...the 3D sensor has been replaced with a 2D sensor." (page 10)
    • "The principle of operation of the Stellaris 2D, Stellaris 2D Ceph, Stellaris 3D, Stellaris 3D Ceph devices remains the same as the predicates. The difference is the type of sensors used which work on similar principles as the sensors found in the predicate devices." (page 7)

    There is no mention of any AI or machine learning components within the device itself for diagnostic or image processing purposes that would require specific performance criteria or a study as outlined in the request. The "reconstruction algorithm" mentioned is standard for CT and panoramic imaging, not an AI/ML algorithm requiring separate clinical performance validation from the device's image acquisition capabilities.

    Therefore, I cannot extract the requested information as it is not present in the provided text. The document describes a traditional 510(k) submission for an imaging device, demonstrating substantial equivalence through technical characteristics, safety standards (IEC, EN), software standards (EN 62304), and biocompatibility (ISO 10993-1).

    In summary, none of the requested information regarding AI/ML acceptance criteria or a comparative study proving device performance against such criteria can be found in this document.

    AI/ML Overview

    This document is a 510(k) summary for the Stella BIO device, which is a neuromuscular electronic stimulator, non-implantable incontinence device, and biofeedback device. The purpose of this summary is to demonstrate that the Stella BIO device is substantially equivalent to a legally marketed predicate device, the Stiwell med4 (K080950).

    Key Acceptance Criteria and Device Performance:

    The document primarily focuses on demonstrating substantial equivalence by comparing the Stella BIO to its predicate device across various "designations" (Powered Muscle Stimulator, Functional Electrical Stimulation, Transcutaneous Electrical Nerve Stimulation, Incontinence Programs, Biofeedback). Instead of defining explicit acceptance criteria with numerical targets as one might for a diagnostic AI, the acceptance criteria here are implicitly met by demonstrating that any differences between the new device and the predicate device, or adherence to relevant voluntary standards (IEC, ANSI/AAMI, FDA guidance), do not raise new questions of safety or effectiveness.

    Therefore, the "acceptance criteria" table below is constructed by extracting the key comparative metrics and the conclusions drawn regarding their impact on safety and effectiveness.

    2. Sample Size and Data Provenance:

    This document is a 510(k) summary for a physical medical device (neuromuscular stimulator) and associated software, not a diagnostic AI/ML model that would typically involve a "test set" of clinical data to establish diagnostic performance. Therefore, the concepts of "sample size used for the test set" and "data provenance" (country, retrospective/prospective) in the context of clinical performance are not directly applicable in the way they would be for an AI/ML diagnostic.

    The "testing" mentioned in this document refers to:

    • Bench Testing / Electrical Safety / EMC Testing: These are engineering and performance verification tests performed in a lab setting to ensure the device meets specified electrical, safety, and electromagnetic compatibility standards (e.g., IEC 60601 series). No specific "sample size" is mentioned for these tests, as they are typically conducted on a limited number of devices to demonstrate design compliance.
    • Software Verification and Validation (V&V): This ensures the software functions as intended and mitigates risks. Again, this is a technical V&V process, not a clinical data-driven "test set."
    • Usability Testing: This assesses the user interface and safety of use.
    • Biocompatibility Testing: For materials in contact with the body.

    The document does not describe a clinical study with patients or a "test set" of clinical data adjudicated by experts to prove diagnostic accuracy or clinical effectiveness for the device's indications for use. The substantial equivalence is argued based on technological characteristics and compliance with recognized standards, assuming that the predicate device's clinical performance and safety profile are well-established.

    3. Number of Experts used for Ground Truth and Qualifications:

    Not applicable, as this is solely based on substantial equivalence to a predicate device and compliance with engineering standards, rather than a clinical study requiring expert adjudication of ground truth for a test set.

    4. Adjudication Method for the Test Set:

    Not applicable for the reasons stated above.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:

    No, an MRMC comparative effectiveness study was not done. The document does not describe any clinical studies involving human readers or the measurement of human reader improvement with or without AI assistance. This device is not an AI diagnostic tool in the typical sense that would necessitate such a study.

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

    No standalone clinical performance study was done. The document focuses on the technical performance of the device's stimulation and biofeedback functions, its safety, and its electromagnetic compatibility through bench testing and compliance with recognized standards. This is not a software-only diagnostic AI that would generally have a "standalone performance" measurement against clinical ground truth.

    7. The Type of Ground Truth Used:

    For the purpose of this 510(k) submission, the "ground truth" is that the predicate device (Stiwell med4) is already legally marketed and presumed safe and effective for its intended uses. The "proof" is the demonstration through engineering tests and comparison of technical specifications that the new device (Stella BIO) is "substantially equivalent" to this established predicate, meaning its differences do not raise new questions of safety or effectiveness. There is no clinical "ground truth" derived from patient outcomes or expert consensus on a test set mentioned.

    8. The Sample Size for the Training Set:

    Not applicable. This device is not an AI/ML model that undergoes "training" on a dataset. The software within the device is validated against its functional requirements and safety specifications, rather than being "trained" on data.

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

    Not applicable, as there is no training set for an AI/ML model for this device.

    AI/ML Overview

    The provided text is a 510(k) summary for the Stellar M22 for Intense Pulsed Light (IPL) and Laser system. This document outlines the device's intended use, technological characteristics, and compares it to a predicate device (M22 System, K170060) to establish substantial equivalence.

    However, the summary does not include specific acceptance criteria or details of a study that proves the device meets those criteria in a quantitative sense as often seen in clinical performance studies with specific endpoints. Instead, it describes "Performance Data" in the context of design verification, compliance with standards, and software validation to demonstrate that modifications to the device do not raise new questions of safety or effectiveness compared to the predicate device.

    Therefore, many of the requested items (e.g., sample size for test set, number of experts for ground truth, MRMC study, standalone performance) are not detailed in this type of regulatory submission, as it focuses on demonstrating substantial equivalence rather than proving a specific diagnostic accuracy or treatment efficacy de novo.

    Below is a summary based on the information provided, with "N/A" for information not present in the document.

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

    The document does not explicitly present acceptance criteria in a quantitative table format that measures specific performance metrics against a defined threshold. Instead, it focuses on demonstrating that the Stellar M22 device's modifications do not introduce new safety or effectiveness concerns compared to its predicate. The "reported device performance" is framed in terms of functional verification and compliance with standards.

    Acceptance Criteria CategoryReported Device Performance/Compliance
    Design Verification & ValidationTests performed to validate modifications to the device (specifics not detailed)
    Risk AnalysisCompliance with ISO 14971
    Electrical SafetyCompliance with IEC 60601-1
    Electromagnetic Compatibility (EMC)Compliance with IEC 60601-1-2
    IPL CompatibilityCompliance with IEC 60601-2-57
    Software Verification & ValidationTests performed (specifics not detailed)
    Technological Characteristics EquivalenceThe device's technological characteristics (wavelength, pulse duration, maximum fluence, etc.) are substantially equivalent to the predicate, with minor modifications not raising new safety/effectiveness questions (see detailed comparison table in the source text).

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

    N/A - The document describes general performance data related to engineering verification and validation, and compliance with standards. It does not refer to a clinical "test set" with a specific sample size of patients or images for diagnostic or therapeutic performance evaluation. The data provenance is also not specified in terms of country of origin or retrospective/prospective nature, as this is not a clinical study report.

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

    N/A - No clinical "test set" requiring ground truth established by experts is described in this regulatory submission for substantial equivalence.

    4. Adjudication method for the test set

    N/A - No clinical "test set" or adjudication method is described.

    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

    N/A - This document does not describe an MRMC comparative effectiveness study or involve AI assistance for human readers. The device is a laser and IPL system for dermatological procedures, not an AI-powered diagnostic tool.

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

    N/A - This device is a medical instrument (laser and IPL system), not an algorithm or AI system. Therefore, standalone algorithm performance is not applicable.

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