    Device Description

    The LightScalpel LS-2010 SX, LS-2010 FX, and LS-2010 DX laser systems are mobile platforms that utilize a radio frequency (RF) excited carbon dioxide (CO2) laser tube to produce an infrared beam at a nominal 10.6 µm wavelength. Output parameters are summarized in Table 1. Laser energy is conducted to the point of application by a flexible fiber waveguide and handpiece assembly. Laser system operation is controlled by operator input on a touch-screen display panel.

    A "calibration port" on the side of the laser systems allows checking and setting the power emitted from the distal laser aperture to the internal power meter and serves as a check on fiber waveguide transmission efficiency. Laser system power, rates, and durations are adjustable as tabulated below (7):

    The laser systems have safety features complying with requirements in 21 CFR 1040. Performance Standards for Light Emitting Products.

    Primary safety features are as follows:

    System On-Off Keyswitch, Emergency Stop Switch, Remote Interlock, Fiber Interlock, Beam Blocking Shutter, Internal Laser Power Detector, RF Power Monitor, and required Laser Safety Labels and Labeling.

    AI/ML Overview

    This document is a 510(k) summary for the LightScalpel® LS-2010 SX, LS-2010 FX, and LS-2010 DX CO2 Laser Systems. It establishes substantial equivalence by comparing the device to predicate devices and provides non-clinical performance data.

    Here's the breakdown of the acceptance criteria and the study that proves the device meets them, based on the provided text:

    1. Table of acceptance criteria and the reported device performance:

    The document doesn't explicitly state "acceptance criteria" in a quantitative, measurable table as one might find for a software or diagnostic device. Instead, it relies on demonstrating substantial equivalence to predicate devices in several technological characteristics. The "performance" is implicitly deemed acceptable if these technological characteristics are sufficiently similar to those of legally marketed predicate devices.

    The table below summarizes the technological characteristics compared across the new devices and predicate devices. The "reported device performance" is essentially the listed specifications of the LightScalpel LS-2010 SX, LS-2010 FX, and LS-2010 DX.

    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. The submission is for a laser surgical instrument, and the evaluation relies on a comparison of technological characteristics and non-clinical bench testing, not a clinical study with a patient "test set".
    • Data Provenance: Not applicable in the context of patient data. The non-clinical performance data is generated internally by LightScalpel LLC through "electrical safety and output characteristics" testing (Bench Testing section). The country of origin of the data would be the US, where LightScalpel LLC is located. The data is prospective, generated specifically for this submission.

    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 not an AI/diagnostic device that requires expert-established ground truth on a test set. The "ground truth" for the device's technical specifications is established through internal engineering and testing processes. The FDA's review process itself involves experts in medical device regulation and technology.

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

    • Not applicable. There is no "test set" in the context of clinical images or patient cases 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 a conventional CO2 laser surgical instrument, not an AI-assisted diagnostic or clinical decision support tool. Therefore, an MRMC study related to AI improvement is irrelevant.

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

    • Not applicable. This device has no standalone algorithmic component for performance evaluation without human interaction. Its performance is directly tied to its physical operation and energy delivery.

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

    • For the technical comparison: The "ground truth" for the comparison is the published technical specifications of the predicate devices, which have already gone through regulatory clearance and are considered substantially equivalent for their intended uses.
    • For the new device's performance: The ground truth for the device's own reported performance values (e.g., power output, wavelength) is established through internal "electrical safety and output characteristics" bench testing, as stated in Section 8 of the summary. This would involve calibrated measurement equipment and adherence to recognized standards for laser performance testing.

    8. The sample size for the training set

    • Not applicable. This is not an AI/machine learning device that requires a training set.

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

    • Not applicable. There is no training set for this device.

The RF laser drive is modulated to provide additional pulsed and superpulse emission modes selected from the laser system control panel.

    AI/ML Overview

    The provided document is a 510(k) summary for the LightScalpel LS-1005 CO2 Laser System. This type of document is a premarket notification for new medical devices, demonstrating substantial equivalence to a legally marketed predicate device. It primarily focuses on comparing the new device's technological characteristics and intended use to existing, cleared devices.

    As such, the provided text does not include information about acceptance criteria for device performance in the context of clinical or standalone studies using AI. It describes the device's technical specifications and safety standards, but not performance metrics like sensitivity, specificity, or accuracy that would typically be evaluated in a study demonstrating how well a device meets specific acceptance criteria that are relevant to an image-based AI medical device.

    Therefore, I cannot extract the requested information regarding acceptance criteria, device performance, sample sizes for test/training sets, ground truth establishment, expert adjudication, or MRMC/standalone studies, as these aspects are not part of this 510(k) submission.

    The document states:

    • "Device performance evaluation did not involve Animal of Clinical Testing." (Page 4, Section 9)
    • "The LightScalpel LS-10 CO2 Laser System has been evaluated for performance equivalent to predicate devices through a combination of (1) verification and validation tests per product requirements and specifications and (2) inspections and tests derived from applicable regulations and safety standards as noted below." (Page 4, Section 8)

    This means the evaluation for this medical device primarily focused on meeting engineering and safety standards, and demonstrating substantial equivalence to existing devices through characteristic comparison, rather than through clinical performance studies with specific statistical acceptance criteria for diagnostic accuracy or similar metrics.

    AI/ML Overview

    The provided document is a 510(k) Summary for the LightScalpel LS-10 CO2 Laser System. This document focuses on demonstrating substantial equivalence to predicate devices rather than providing detailed acceptance criteria and a study proving device performance against those criteria in the context typically seen for AI/ML medical devices.

    The information primarily describes the device, its intended use, and a comparison of its technological characteristics to predicate devices. It does not contain the specific type of acceptance criteria and performance study details usually associated with AI/ML device evaluations (e.g., sensitivity, specificity, AUC, etc.).

    Here's an attempt to extract relevant information based on the prompt, acknowledging the limitations of the document:

    1. Table of Acceptance Criteria and Reported Device Performance:

    Based on the document, the "acceptance criteria" appear to be defined by showing similar technological characteristics and performance to predicate devices and compliance with relevant safety and performance standards. The "reported device performance" is essentially the LightScalpel LS-10's specifications and features.

    IEC 60825-1, Safety of laser products Part 1Verified (stated in 510(k) Summary)

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

    The document explicitly states: "Device performance evaluation did not involve Animal or Clinical Testing." This indicates there was no "test set" in the traditional sense of patient or sample data for evaluating clinical performance. The evaluation was based on verification and validation tests per product requirements and specifications, and inspections and tests derived from applicable regulations and safety standards. Details on the specific "sample size" of components tested or the nature of these verification/validation tests are not provided.

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

    Not applicable, as no animal or clinical testing was conducted. The "ground truth" for demonstrating equivalence was based on meeting established engineering specifications and compliance with international standards, which would be assessed by engineers and regulatory experts, not clinical experts establishing ground truth for a medical image or diagnostic output.

    4. Adjudication Method for the Test Set:

    Not applicable, as no animal or clinical testing was conducted that would require an adjudication method by expert reviewers.

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

    No, an MRMC study was not done. The device is a CO2 laser system, not an AI/ML diagnostic or assistive tool that would typically be evaluated with MRMC studies for human reader performance.

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

    The concept of "standalone performance" as it relates to AI algorithms is not applicable here. The device is a surgical instrument. Its "performance" is inherent in its physical operation (e.g., power output, wavelength, safety features) and its ability to achieve the intended surgical effects when operated by a clinician.

    7. The Type of Ground Truth Used:

    The "ground truth" in this context refers to engineering specifications, safety standards, and the established performance characteristics of the predicate devices. For instance, the stated power output (2-10 Watts CW) is verifiable through direct measurement, representing its "ground truth" for that parameter. Compliance with standards like IEC 60601-2-22 serves as a "ground truth" for safety and essential performance requirements.

    8. The Sample Size for the Training Set:

    Not applicable. This is not an AI/ML device that undergoes "training." The device is a manufactured hardware system.

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

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

    The provided text describes a 510(k) submission for the LightScalpel family of handpiece tips for CO2 surgical lasers. The submission focuses on demonstrating substantial equivalence to a predicate device, primarily due to a change in the sterilization method.

    Here's an analysis of the acceptance criteria and supporting study based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance:

    Acceptance CriteriaReported Device Performance
    Sterilization to 10⁻⁶ SAL (Sterility Assurance Level)Validation of sterilization parameters required for obtaining 10⁻⁶ SAL utilizing radiation sterilization was provided.
    Identical construction and performance to predicate deviceThe devices are described as "identical to the predicate products, utilizing the same specifications, materials and methods."
    No new indications for use sought beyond predicate device"No new indications for use are sought beyond those associated with the predicate device."

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

    • Sample size for test set: Not explicitly stated in the provided text. The nonclinical performance data refers to "validation of sterilization parameters," which would involve a specific number of sterilization cycles and tests, but the exact sample size (e.g., number of test units) is not given.
    • Data Provenance: The nature of the study (sterilization validation) suggests a controlled laboratory setting. The origin (e.g., country) of the tests or where the validation was performed is not mentioned. It is an internal study conducted by the manufacturer to support their 510(k) submission.

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

    • Not applicable. This submission does not involve clinical data or expert evaluation of device performance in a diagnostic or treatment context that would require expert-established ground truth. The primary focus is on sterilization efficacy.

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

    • Not applicable. There is no mention of adjudication, as the study is a nonclinical validation of sterilization rather than an assessment of subjective interpretations.

    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

    • No. An MRMC study was not done. The device is a surgical laser handpiece tip, not an AI-assisted diagnostic or treatment system involving human readers.

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

    • No. The device is a physical medical instrument, not a software algorithm.

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

    • The "ground truth" for the sterilization validation would be a predetermined sterility assurance level (SAL), specifically 10⁻⁶ SAL. This is an objective, quantitative standard. The validation demonstrates that the chosen sterilization process consistently achieves this sterility level under defined conditions.

    8. The sample size for the training set:

    • Not applicable. This is a nonclinical validation study for a physical device, not a machine learning model that requires a 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 model.
