    AI/ML Overview

    This document describes the 510(k) Summary Statement for the Coherent ULTRAPULSE Carbon Dioxide Surgical Lasers, and as such, it focuses on demonstrating substantial equivalence to existing predicate devices rather than providing a detailed study proving performance against specific acceptance criteria for a novel device.

    Therefore, many of the requested categories for a study proving device meets acceptance criteria will not be directly applicable or fully available in this type of submission. This is typical for 510(k) premarket notifications.

    Here's an analysis based on the provided text:

    Acceptance Criteria and Device Performance

    The document does not explicitly state "acceptance criteria" in the traditional sense of a specified threshold for a new device's performance (e.g., "sensitivity must be > 90%"). Instead, its primary goal is to demonstrate that the ULTRAPULSE CO2 laser is substantially equivalent to predicate devices. The "performance" is implicitly deemed acceptable if it's comparable to these already cleared devices, and if clinical studies support its safety and effectiveness for various specific applications.

    Therefore, a table of explicit acceptance criteria and corresponding performance metrics, as one might see for a novel diagnostic algorithm, cannot be fully constructed from this text. However, we can infer the "performance" through the stated benefits and comparisons to predicate devices in the clinical studies cited.

    Inferred "Acceptance Criteria" and Reported "Performance"

    Acceptance Criteria (Inferred from Clinical Study Outcomes)Reported Device Performance (Summary from Studies)
    Increased Sub-Epidermal Collagen (Skin Resurfacing)"Clinical study demonstrated that skin resurfacing of wrinkles, rhytids, and furrows with the ULTRAPULSE CO2 laser increases the amount of sub-epidermal collagen."
    Cosmetic Results Equivalent to Cold Steel Blepharoplasty"Clinical studies…demonstrate that CO2 laser blepharoplasty provides cosmetic results that are equivalent to cold steel blepharoplasty..."
    Faster Blepharoplasty Procedure Time"...is up to 33% faster than cold steel blepharoplasty..."
    Improved Hemostasis & Visualization (Blepharoplasty)"...provides good hemostasis and visualization of the surgical field..."
    Reduced Ecchymosis, Edema, Bruising (Blepharoplasty)"...results in less ecchymosis, edema, and bruising when compared to cold steel."
    Faster Operative Times (Hair Transplantation)"Clinical studies…demonstrate that the use of ULTRAPULSE CO2 surgical lasers, as compared to cold steel, results in faster operative times..."
    Reduced Bleeding (Hair Transplantation)"...reduced bleeding..."
    No Compression of Laser Created Sites (Hair Transp.)"...no compression of laser created sites (due to removal of scalp tissue vaporized from laser created sites)..."
    Greater Hair Density (Hair Transplantation)"...and greater hair density (due to removal of scalp tissue vaporized from laser created sites)."
    Overall Safety and Effectiveness"Clinical data was provided to demonstrate that the Coherent ULTRAPULSE Carbon Dioxide Surgical Lasers are safe and effective, when indicated for use for specific applications in the medical specialties of dermatology; plastic surgery; podiatry; neurosurgery; gynecology; otorhinolaryngology (ENT); and general surgery." / "Clinical study results demonstrated Coherent ULTRAPULSE CO2 Surgical Lasers are safe and effective for use in a variety of specific indications for use in a variety of medical specialties..." (This is a general statement rather than a specific metric.)

    Study Details for Demonstrating Safety and Effectiveness (Implied "Test Set" Data)

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

      • The document refers to "Clinical study" (singular) for skin resurfacing and "Clinical studies" (plural) for blepharoplasty and hair transplantation.
      • Specific sample sizes are not provided in this summary.
      • Data Provenance: The studies are published in medical journals (e.g., J Dermatol Surg Oncol, Ophthalmology, Dermatol Surg). The country of origin is not explicitly stated in this summary, but the journals and authors suggest primarily North American (US) origins. These would be considered prospective or retrospective clinical studies, depending on the design of the individual cited papers.
    2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • This information is not provided in the 510(k) summary. These details would typically be found within the individual clinical study publications. The studies are authored by physicians (e.g., dermatologists, plastic surgeons, ophthalmologists), who would be the "experts" performing the procedures and evaluating outcomes, but the number and specific qualifications (years of experience) are not summarized here.
    3. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

      • This information is not provided in the 510(k) summary. Given the nature of surgical outcomes measured (e.g., hemostasis, edema, cosmetic results, hair density), adjudication methods for a "test set" in the context of image interpretation are not directly applicable. Evaluations would have been clinical assessments by the treating physicians and potentially objective measures (e.g., microscopy for collagen, photographic assessment for cosmetic outcome).
    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:

      • No, an MRMC study was not done. This device is a surgical laser, not an AI-assisted diagnostic tool. The comparisons are between the device (CO2 laser) and traditional surgical methods (cold steel), not between human readers with and without AI.
    5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • Not applicable. This is a surgical device, not an algorithm. Performance is inherently tied to human use by a surgeon.
    6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

      • The "ground truth" or primary endpoints for these studies are based on clinical outcomes data and expert assessment.
        • For skin resurfacing: Evidence of "increased sub-epidermal collagen" would likely come from histological analysis (pathology).
        • For blepharoplasty and hair transplantation: "Cosmetic results," "hemostasis," "ecchymosis," "edema," "bruising," "operative times," "bleeding," "compression of sites," and "hair density" are all direct clinical observations and/or quantitative measurements (e.g., time) from actual patient treatment. These outcomes are assessed by the treating surgeons or independent evaluators.
    7. The sample size for the training set:

      • Not applicable. This is a hardware surgical device, not a machine learning algorithm that requires a "training set." The concept of a training set is irrelevant here.
    8. How the ground truth for the training set was established:

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

    AI/ML Overview

    This submission is a 510(k) Summary Statement for a medical device (Coherent VersaPulse Aesthetic Surgical Lasers) and does not contain the detailed study information typically found in a clinical trial report or a comprehensive regulatory submission. The document explicitly states it's a "Rationale for Substantial Equivalence," meaning the primary argument for approval is that the device is similar enough to already marketed devices. Therefore, a formal study with acceptance criteria, sample sizes, ground truth establishment, expert adjudication, or MRMC studies is not described in the provided text.

    Instead, the document focuses on demonstrating substantial equivalence to predicate devices. This approach to regulatory clearance (510(k)) often relies on comparing device features and performance to existing, legally marketed devices, rather than conducting new, elaborate clinical trials to establish de novo safety and effectiveness with specific performance metrics and acceptance criteria.

    However, based on the information provided, here's what can be extracted and inferred, addressing your points where possible:


    1. Table of Acceptance Criteria and Reported Device Performance

    No specific numerical acceptance criteria (e.g., minimum sensitivity, specificity, accuracy percentages) are provided in the document, nor are specific performance metrics like "sensitivity" or "specificity" reported. The acceptance criteria essentially revolve around demonstrating equivalence in design, function, and intended use to predicate devices, and demonstrating acceptable physical test results and biocompatibility.

    Acceptance Criteria (Inferred from Substantial Equivalence Logic)Reported Device Performance (Summary)
    Indications for Use: Same as predicate devicesShares the same indications for use as predicate devices. Intended for photothermolysis of soft tissue (532 nm, 1064 nm, 755 nm) and excision, incision, ablation, vaporization, and coagulation of soft tissue (2940 nm).
    Design Features: Similar to predicate devicesSimilar design features (control system, wavelengths, beam quality, laser tube configuration, active medium, cooling system, controls and displays).
    Functional Features: Similar to predicate devicesSimilar functional features (power, repetition rate, energy, spot sizes, treatment areas).
    Laser Energy Equivalence: Equivalent to currently marketed surgical lasersIn-vivo testing performed to demonstrate that the laser energy provided is equivalent to that provided by currently marketed surgical lasers. (No specific metrics or thresholds reported).
    Biocompatibility: New delivery device materials are biocompatibleTesting performed to establish the biocompatibility of new delivery device materials that could potentially contact patient tissue. (No specific metrics or thresholds reported).
    Safety and Effectiveness: Assumed equivalent to predicate devicesFound to be substantially equivalent to similar currently marketed surgical laser devices. Physical test results demonstrated acceptable performance characteristics.

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

    • Test Set Sample Size: Not specified. The document mentions "In-vivo testing" and "Testing is performed to establish biocompatibility," but it does not provide any details on the number of subjects, animals, or test cases involved in these tests.
    • Data Provenance: Not specified. It's highly likely this was internal company testing, but no country of origin is mentioned. The description "In-vivo testing" suggests prospective testing, but without further detail, it's impossible to confirm.

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

    • This information is not provided. Given the nature of a 510(k) for a laser device, "ground truth" as it would be understood in an AI/diagnostic study (e.g., expert consensus on image interpretation) is not directly applicable. The "ground truth" here would likely relate to objective measurements of laser output and observed tissue effects, or standard biocompatibility assessments, rather than expert judgment on complex cases.

    4. Adjudication Method for the Test Set

    • Not applicable/Not provided. There's no indication of any expert adjudication process for the "in-vivo testing" or biocompatibility assessments mentioned. These typically involve objective measurements and established scientific protocols rather than subjective consensus.

    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 comparative effectiveness study was not done. This type of study is relevant for diagnostic devices that assist human interpretation (e.g., AI for radiology). This device is a surgical laser, and its primary function is to deliver energy for therapeutic purposes, not to provide diagnostic information or assist human "readers." Therefore, the concept of "human readers improving with AI assistance" is not relevant to this device's regulatory submission as described.

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

    • Not applicable/Not provided. This device is a physical surgical laser, not a software algorithm. Its "performance" is inherent in its physical output and functional capabilities (e.g., laser power, wavelength, tissue effects). Its operation requires a human operator, so an "algorithm-only" or "standalone without human-in-the-loop" performance is not a relevant concept for this type of device.

    7. The Type of Ground Truth Used

    • For "in-vivo testing" to demonstrate laser energy equivalence, the ground truth would likely be objective measurements of laser parameters (e.g., power output, energy density, pulse duration) and possibly observed tissue effects (e.g., depth of photocoagulation, ablation rates) against established benchmarks or the performance of predicate devices.
    • For "biocompatibility testing," the ground truth would be established through standardized testing protocols (e.g., ISO standards for cytotoxicity, irritation, sensitization) which involve specific assays and observational criteria to determine if a material is biologically compatible.
    • The document does not explicitly state these, but these are the standard "ground truths" for such tests.

    8. The Sample Size for the Training Set

    • Not applicable/Not provided. This device is a hardware surgical laser, not an AI or machine learning algorithm. Therefore, there is no "training set" in the context of AI development. The device's design and engineering are based on established physics and medical knowledge, rather than being "trained" on data.

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

    • Not applicable/Not provided for the same reasons as point 8. There is no training set for this type of device.
