    Intended Use

    The Profound Matrix System is intended for dermatological procedures, as follows:

    The Matrix Pro applicator is indicated for general dermatological procedures for electrocoagulation and hemostasis. The Matrix Pro applicator is indicated for the percutaneous treatment of facial wrinkles in patients with Fitzpatrick Skin Types I-IV.

    The Sublative RF applicator is indicated for dermatological procedures requiring ablation and resurfacing of the skin, and for the treatment of facial wrinkles. At higher energy levels greater than 62mJ/pin, the Sublative RF applicator is limited to Fitzpatrick Skin Types I-IV.

    The Sublime applicator is indicated for non-invasive wrinkle treatment. At higher energy levels, greater than 100 J/cm³, the Sublime applicator is limited to Fitzpatrick Skin Types I-IV.

    Device Description

    Profound Matrix is a system that combines three existing technologies and applications for dermatological procedures. Each respective technology is used in one of the three applicators designed for the Profound Matrix System. These three applicators are named: Matrix Pro, Sublative RF and Sublime.

    The system console consists of a CPU, power supply, RF pulse generator, I/O board, splitter/distribution board and footswitch board. When the system is powered up, the user can select between user mode and service/maintenance mode. After selecting user mode and entering the required password, the user is requested to choose between the Matrix Pro, the Sublative RF or the Sublime applicators. Only one applicator can be used to treat a patient at any given time.

    The user interfaces with the Profound Matrix System and applicators' settings through the 15″ touch screen. Each of the applicators have a finger trigger that can be used to activate the applicator or alternatively the end user can use the footswitch to activate the applicator.

    Matrix Pro: The Matrix Pro applicator is designed to deliver bipolar, non-ablative radiofrequency energy through a 7x7 matrix/grid of sterile microneedles to the skin in a fractional manner. The microneedles can be set up to pulse up to a maximum of three depths during each insertion of the matrix/grid of microneedles with a maximum depth of up to 3.5mm. The Matrix Pro applicator delivers the right amount of energy at the precise depth, every time. The technology of the Matrix Pro applicator combines adjustable depth, energy, and real time impedance monitoring for customizable and consistent results. The Profound Matrix system monitors tissue impedance across the 3 modalities, in real-time, while simultaneously adjusting RF energy pulse duration and power output. The result is an accurate dose of RF energy delivery with every treatment application for consistent treatment outcomes, independent of patient-to-patient, body location, skin hydration, and procedural-related impedance variations.

    Sublative RF: The Sublative RF applicator delivers bipolar radiofrequency (RF) to the skin surface in a fractional manner via an array of multi-electrode pin tips, which results in heating of both the demarcated spots to temperatures that ablate and resurface at contact points of the multi-electrode pins while also delivering heat in a wide diffuse manner to the dermis.

    Sublime: The Sublime applicator uses a combination of an infrared (IR) light source and bipolar radiofrequency (RF) to bulk heat the dermis and affect dermal collagen in order to treat wrinkles. The bulk heating of the dermal layers refers to the gradual and gentle accumulation of heat with each additional pass performed.

    AI/ML Overview

    Here's a breakdown of the acceptance criteria and the study proving the device meets them, based on the provided FDA 510(k) summary for the Profound Matrix System with the Matrix Pro Applicator.

    Device Description

    The Candela Vbeam Family of Pulsed Dye Lasers includes both the Vbeam Prima and Vbeam Perfecta Laser Systems.
    The Vbeam Prima Laser System has been previously cleared for both port wine stains, and hemangiomas under K183452.
    The Vbeam Perfecta (Candela Family of Pulse Laser Systems) has been previously cleared for both port wine stains, and hemangiomas under K050673.
    This 510(k) Premarket Notification is to expand the indications for use for the Candela Vbeam Family of Pulsed Dye Lasers for the Vbeam Prima Laser System and Vbeam Perfecta to include the pediatric population for treatment of cutaneous capillary malformations, also known as port wine stains (PWS), and infantile hemangiomas (IH) / congenital hemangiomas for the 595 nm wavelength. There is no new technology being introduced than what has been previously cleared Vbeam Prima Laser System under its predicate K183452 and Vbeam Perfecta under its predicate K050673.

    AI/ML Overview

    The provided text from the FDA 510(k) summary (K230990 for Candela Vbeam Family of Pulsed Dye Lasers) does not contain information about acceptance criteria or a study proving that the device meets specific performance criteria. Instead, it details the substantial equivalence determination for an expanded indication (treatment of cutaneous capillary malformations and infantile/congenital hemangiomas in the pediatric population) for devices (Vbeam Prima and Vbeam Perfecta) that were previously cleared.

    The 510(k) summary states that:

    • There are no new technologies being introduced.
    • The device is identical in design, function, and intended use to its previously cleared Vbeam Prima Laser System (K183452) and Vbeam Perfecta (K050673) predicates.
    • The expanded indications do not raise any new concerns of safety or effectiveness.

    Therefore, the performance data provided relies on:

    1. Bench testing: "based on the established testing previously cleared under Vbeam Prima Laser System under its predicate K183452 and Vbeam Perfecta under its predicate K050673. There are no changes in the design therefore the subject Candela Vbeam of Pulsed Dye Lasers is based on the established performance testing of the device's predicates." This implies that prior acceptance criteria for the predicate devices are considered met for the new device due to identical design. No specific quantitative acceptance criteria or results from this bench testing are provided in the document.

    2. Clinical Performance: A systematic literature search was conducted to support the expanded pediatric indications. This is not a direct study proving the device meets an acceptance criterion "for the device itself," but rather a review of existing clinical evidence to support the safety and effectiveness of the treatment method (Vbeam 595-nm PDL) for the expanded indications.

    Given this, I cannot fill in a table of acceptance criteria and reported device performance directly from this document, as the document explicitly states there are no changes to the device itself and it relies on the predicate's established performance. The "performance data" presented for the new indication is effectively a literature review.

    However, I can extract information related to the clinical literature review used to support the new indication:

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

    • Acceptance Criteria for Device (Implied): The device (Vbeam Prima and Vbeam Perfecta) must perform identically to its predicate devices, as no design changes were made. The performance is assessed on the safety and effectiveness of the 595-nm PDL for the target conditions based on existing literature. No specific quantitative performance metrics (e.g., laser fluence accuracy, pulse stability) are provided in this summary for the "acceptance criteria" of the device itself for this 510(k) submission, as it relies on the prior clearance of the predicate.
    • Reported Device Performance (from literature review): The studies reviewed "support the intended indications for use of the Vbeam 595-nm PDL to treat cutaneous capillary malformations, also known as port wine stains (PWS), and infantile hemangiomas (IH) / congenital hemangiomas in the pediatric population." Details on specific outcome measures (e.g., percentage improvement in lesion appearance, adverse event rates) from these studies are not summarized or quantified in this 510(k) document, only that the literature generally supports the use.

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

    • Test Set (Literature Review): A total of 33 articles were identified.
      • Total Patients: 7,725
      • Pediatric Patients (Hemangioma): 5,692 (4,782 IH, 910 congenital)
      • Pediatric & Adult Patients (PWS/Capillary Malformation): 1,354 pediatric and 679 pediatric and adult.
    • Data Provenance: The studies were conducted globally, specifically listed as from the USA, UK, Europe, and Asia (including China, Japan, Taiwan, India, and the Middle East). The studies included randomized controlled, prospective, open label, evaluator-blinded clinical trials, or retrospective evaluator-blinded studies. The data is retrospective in the sense that it relies on previously published research.

    3. 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. The ground truth for the efficacy and safety of the treatment would have been established by the methods within each of the 33 individual published studies (e.g., clinical assessment by dermatologists, photographic evaluation, patient-reported outcomes). The 510(k) summary only reviews the conclusions of these studies.

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

    • This information is not provided as it's a literature review, not a de novo clinical study with a central adjudication panel. Adjudication methods would vary by individual study.

    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 MRMC study was performed or referenced in this document. This submission is for a laser device, 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 laser device for treatment, not an algorithm.

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

    • The ground truth for the effectiveness of the treatment, as drawn from the literature review, is based on clinical outcomes data reported in peer-reviewed articles. This would typically include assessments of lesion clearance/improvement, photographic documentation, and safety outcomes (adverse events). Specific types of ground truth would vary by individual study design (e.g., some studies might use standardized scales for improvement, others might rely on subjective expert assessment).

    8. The sample size for the training set:

    • Not applicable. This is a laser device, not a machine learning algorithm requiring a "training set." The clinical literature review serves as the evidentiary basis for the expanded indication.

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

    • Not applicable. As above, no training set for a machine learning model is involved.

    Device Description

    The PicoWay Laser System is a solid-state laser capable of delivering energy at wavelengths of 1064 nm, 532 nm, or 730 nm, at extremely short duration in the range of 240-500 (ps). The laser system contains one 755 nm (Alexandrite) laser head which is used to 'pump' (create) the 1064 / 532nm wavelengths. The outputs of the two lasers are optically combined on the laser rail so that their beam paths are identical as they exit the laser system. This allows the use of a single delivery system which can output either the 532nm or 1064nm wavelengths. The 532nm or 1064nm output energy is delivered to the skin through an Articulated Arm and Zoom Handpiece (HP) delivery system. There are also 3 hand pieces (Resolve), one for 1064nm and two for 532nm (low energy and high energy), which deliver a 10 x 10 array of focused spots to the skin and 1 Axicon hand piece (Resolve Fusion) for 532nm, which delivers a 10 x 10 array of focused and ring spots to the skin.

    AI/ML Overview

    The provided document describes the Candela PicoWay Laser System (K220853) and its substantial equivalence to a predicate device (K191685). The primary difference is the addition of new indications for benign pigmented lesions. The document does not refer to the device as an "AI device" or an "algorithm," but rather a laser system. Therefore, some of the requested information regarding AI device testing (e.g., human-in-the-loop performance, effect size of human improvement with AI, training set details, expert qualifications for ground truth in a test set, adjudication methods) is not directly applicable.

    However, based on the information provided, here's a summary of the acceptance criteria and the study that supports the expanded indications for the PicoWay Laser System, focusing on the clinical evidence for the new indications.

    Acceptance Criteria and Reported Device Performance

    Intended Use

    The PROFOUND MATRIX SYSTEM is intended for dermatological procedures, as follows:

    The MATRIX PRO applicator is indicated for general dermatological procedures for electrocoagulation and hemostasis.

    The SUBLATIVE RF applicator is indicated for dermatological procedures requiring ablation and resurfacing of the skin, and for the treatment of facial wrinkles. At higher energy levels greater than 62mJ/pin, the Sublative RF applicator is limited to Fitzpatrick Skin Types I-IV.

    The SUBLIME applicator is indicated for non-invasive wrinkle treatment. At higher energy levels, greater than 100 J/ cm3, the Sublime applicator is limited to Fitzpatrick Skin Types I-IV.

    Device Description

    The Profound Matrix System combines three existing technologies and applications for dermatological procedures. Each respective technology is used in one of the three applicators designed for the Profound Matrix System. These three applicators are named: Matrix Pro, Sublative RF and Sublime.

    The Matrix Pro applicator is designed to deliver bipolar, non-ablative radiofrequency energy through a 7x7 matrix/grid of sterile microneedles to the skin in a fractional manner. The microneedles can be set up to pulse a maximum of three depths during each insertion of the matrix/grid of microneedles with a maximum depth of up to 3.5mm.

    The Sublative RF applicator delivers bipolar radiofrequency (RF) to the skin surface viaan array of multi-electrode pin tips. The applicator delivers bipolar RF energy to the skin, which results in heating of demarcated spots to temperatures that ablate and resurface at contact points of the multi-electrode pins.

    The Sublime applicator uses a combination of an infrared (IR) light source and bipolar radiofrequency (RF) to bulk heat the dermis and affect dermal collagen in order to treat wrinkles. The bulk heating of the dermal layers refers to the gradual and gentle accumulation of heat with each additional pass performed.

    Important Note: The provided document is a 510(k) Summary, which focuses on demonstrating substantial equivalence to a predicate device rather than providing detailed clinical study results for a novel device. As such, information regarding acceptance criteria for a new clinical performance study, multi-reader multi-case studies, and detailed ground truth establishment for a training set are largely not applicable or not provided in this context. The document explicitly states that "no clinical or animal studies were needed to support this 510(k) Premarket Notification."


    1. Table of Acceptance Criteria and Reported Device Performance

    Since this is a 510(k) submission based on substantial equivalence, there are no explicit "acceptance criteria" for a new clinical performance study with specific metrics like sensitivity or specificity. Instead, the "acceptance criteria" are implied by demonstrating that the device's technical characteristics and performance are comparable to the legally marketed predicate device, and it meets relevant safety and performance standards.

    Acceptance Criterion (Implied by 510(k) for Substantial Equivalence)Reported Device Performance (from Bench Testing)
    Electrical Safety (IEC 60601-1)Passed - Conducted testing and found to be acceptable.
    Electromagnetic Compatibility (EMC) (IEC 60601-1-2)Passed - Conducted testing and found to be acceptable.
    High-Frequency Surgical Equipment Safety (IEC 60101-2-2)Passed - Conducted testing and found to be acceptable.
    Biocompatibility (ISO 10993)Established based on predicate devices and results of ISO 10993 testing.
    Software Verification & Validation (FDA Guidance)Passed - Verification and validation testing conducted, results acceptable for software release, performed per FDA guidance.
    Shelf-life and Transportation TestingPerformed. (Results are not explicitly detailed but are implied to be acceptable for substantial equivalence).
    Human Factors Summative UsabilityPerformed. (Results are not explicitly detailed but are implied to be acceptable for substantial equivalence).
    Thermal Testing (FDA Guidance for Electrosurgical Devices)Performed. (Results are not explicitly detailed but are implied to be acceptable for substantial equivalence).
    Applicator Cleaning and Disinfecting Validation (FDA Guidance)Performed. (Results are not explicitly detailed but are implied to be acceptable for substantial equivalence).
    Ex-Vivo Thermal Damage Equivalence (Matrix Pro vs. Predicate)Showed similar thermal effects (collagen denaturation, voids, and compressed fat cells) at similar depths and (for some settings) widths compared to the predicate (Infini). Noted that Matrix Pro has better energy control due to impedance calculation.

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

    • Test Set Sample Size:
      • For the Ex-Vivo Thermal Damage Evaluation, the sample size was not explicitly specified numerically, but it involved "excised abdominal skin tissue." The samples were treated with "four RF energy levels (1), 2J, 3J and 4J) and included three treatment depths using two depth configurations (dense and spread)."
      • For other bench tests (electrical safety, EMC, software, etc.), the "sample size" refers to the device units tested, which is typically a smaller number to demonstrate compliance with engineering standards.
      • No clinical test set was required or used for this 510(k) submission.
    • Data Provenance:
      • Ex-Vivo Thermal Damage Evaluation: The tissue was "ex-vivo, excised abdominal skin tissue." The country of origin is not specified, but it was likely laboratory bench testing.
      • For other tests like electrical safety, EMC, and software, the data provenance would be internal laboratory testing by Candela Corporation.
      • Retrospective or Prospective: All testing described is prospective bench testing.

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

    • Not Applicable / Not Provided in this context. Since no clinical studies were performed, there was no need for experts to establish ground truth on patient data. The "ground truth" for the ex-vivo thermal damage evaluation would be the observed histological changes, interpreted by the researchers conducting the bench test.

    4. Adjudication Method for the Test Set

    • Not Applicable / Not Provided in this context. As there were no clinical studies and no expert interpretation of patient data for performance metrics, no adjudication method was mentioned.

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

    • No. A Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not performed. The 510(k) summary explicitly states, "Based on the similarities of the device specifications, intended use, indications for use between the Profound Matrix and its predicate device, no clinical or animal studies were needed to support this 510(k) Premarket Notification."

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

    • Yes, in the context of device function. The "performance" described pertains to the standalone device functionality and its components (applicators, software, electrical systems) rather than an AI algorithm. The Ex-Vivo Thermal Damage Evaluation and other bench tests evaluate the device's inherent performance. There is no mention of an AI algorithm in the traditional sense (e.g., for diagnosis or prediction) and therefore no standalone algorithm performance in that context.

    7. The Type of Ground Truth Used

    • For Ex-Vivo Thermal Damage Evaluation: Histological observation of "collagen denaturation consistent with tissue heating" and "voids consistent with broken fat cells membranes and a surrounding layer of compressed fat cells" were the "ground truth" for evaluating the thermal effects. This is a type of laboratory/experimental observation.
    • For other bench tests: The "ground truth" is adherence to established engineering and safety standards (e.g., electrical parameters, software functionality).

    8. The Sample Size for the Training Set

    • Not Applicable. As no clinical or animal studies were performed and no machine learning algorithm for diagnostic or predictive purposes was described, there was no training set in the typical sense for a medical AI device. The device's "training" would be its design and engineering based on existing knowledge and predicate devices.

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

    • Not Applicable. See point 8.

    Device Description

    The GentleMax Pro Plus contains two separate laser heads (Alexandrite and Nd:YAG), which produce laser light outputs of 755 nm and 1064 nm, respectively. The output of each laser head is optically combined on the laser rail, so that their beam paths are identical as they exit the laser system. This allows the use of a single delivery system which can output either 755 nm or 1064 nm wavelengths. The laser system creates a beam of high intensity light that penetrates deep into the skin tissue where it delivers a controlled amount of therapeutic heat. The Dynamic Cooling Device (DCD) protects the upper layers of the skin with a cooling burst of cryogen.

    AI/ML Overview

    This document is a 510(k) premarket notification for the Candela GentleMax Pro Plus laser system, which is a medical device. This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, rather than proving novel effectiveness through clinical studies. As such, the information you're asking for, particularly regarding acceptance criteria and the study that proves the device meets the acceptance criteria in the context of an AI/algorithm-driven medical device, is not directly applicable to this submission.

    This document pertains to a laser surgical instrument, not an AI or algorithm-based diagnostic/therapeutic device. Therefore, the concepts of "test set," "ground truth," "expert consensus," "MRMC studies," and "standalone performance" as they relate to AI model validation are not present here.

    However, I can extract the relevant information about how this device's performance and safety were evaluated to demonstrate substantial equivalence.

    Here's an analysis based on the provided text, addressing your points where applicable and explaining why others are not relevant:


    Device Type: Laser Surgical Instrument for use in General and Plastic Surgery and in Dermatology (Product Code GEX). This is NOT an AI/algorithm-driven device requiring traditional AI model performance evaluation.


    Acceptance Criteria and Reported Device Performance (as relevant for a laser system):

    The "acceptance criteria" for this device are primarily based on demonstrating substantial equivalence to a predicate device (Candela GentleMAX Family of Lasers System, K140122) in terms of design, technological characteristics, intended use, and indications for use. The performance data provided are therefore related to safety and functional equivalency.

    Acceptance Criterion (for Substantial Equivalence to Predicate)Reported Device Performance (GentleMax Pro Plus)
    Technological Characteristics SimilaritySame as Predicate (K140122) for many key features:
    • Wavelengths (755 nm & 1064 nm)
    • Laser Medium (Flashlamp-excited, Solid state Alexandrite and Nd:YAG laser)
    • Aiming Beam (Green diode laser)
    • Maximum Fluence (400 J/cm2 (ALEX), 520 J/cm2 (YAG))
    • Accuracy of Output (± 20%)
    • Operating Modes (Pulse)
    • Energy Delivery (Footswitch & finger switch)
    • Beam Delivery (Lens-coupled optical fiber)
    • Skin Cooling (Cryogen DCD)
    • System Cooling (Ambient Air)
    • Software/GUI/Touch Screen (Yes)
    • Dimensions & Weight
    • Power Supply

    Minor Differences (not raising new safety/effectiveness questions):

    • Maximum Energy (J): Modified: 68 J ALEX; 90 J Nd:YAG (Predicate: 53 J ALEX; 80 J Nd:YAG). This indicates increased power.
    • Spot Size (mm): Modified: 1.5, 3, 3x10, 5, 6, 8, 10, 12, 15, 18, 20, 22, 24, 26 (Predicate: 1.5, 3, 3x10, 5, 6, 8, 10, 12, 15, 18). New, larger spot sizes added.
    • Repetition Rate (Hz): Modified: 1-10 Hz (Predicate: 1-10 Hz). Text notes "faster repetition rate" but table shows same range. This likely refers to increased maximum repetition rate within the 1-10Hz range for specific parameters, not a change in the overall range.
    • Pulse Duration (ms): Modified: 0.25 - 100 ms (new 2ms) (Predicate: 0.25 - 100 ms). This indicates the addition of a specific 2ms pulse setting option. |
      | Same Intended Use & Indications for Use | The Intended Use/Indications for Use Statement is unchanged from the predicate device (K140122). |
      | Compliance with Electrical Safety and EMC Standards | Complies with IEC 60825-1, IEC 60601-1-2, IEC 60601-1, IEC 60601-2-22. |
      | Biocompatibility | Established based on predicate devices and results of ISO 10993-5 and ISO 10993-10 series of testing (acceptable). |
      | Software Verification & Validation | Testing conducted and results were found acceptable for software release, performed per FDA's guidance document "Guidance for the Content of Premarket Submission for Software Contained in Medical Devices". |

    Since this is not an AI/algorithm-driven device, the following points are not applicable and are not discussed in the provided 510(k) summary:

    • 2. Sample size used for the test set and the data provenance: Not applicable. There's no "test set" in the context of an AI model. Performance evaluation for this laser is primarily functional and safety testing.
    • 3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No image-based "ground truth" or expert review process as would be needed for an AI diagnostic algorithm.
    • 4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
    • 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 device.
    • 6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
    • 7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable.
    • 8. The sample size for the training set: Not applicable. There's no AI model involved that requires a "training set."
    • 9. How the ground truth for the training set was established: Not applicable.

    Summary of Device Evaluation for Substantial Equivalence:

    The manufacturer asserted that the GentleMax Pro Plus is substantially equivalent to its predicate (Candela GentleMAX Family of Lasers System, K140122) because:

    • It has the same intended use and indications for use.
    • It shares similar design and technological characteristics. While some specifications like maximum energy, pulse duration (new 2ms option), and spot sizes (new larger ones) have changed, the manufacturer states these "minor differences do not raise any new types of safety or effectiveness questions because the GentleMax Pro Plus parameters are similar to the predicates."
    • It meets all relevant electrical safety and electromagnetic compatibility standards (IEC 60825-1, IEC 60601-1-2, IEC 60601-1, IEC 60601-2-22).
    • Its biocompatibility was established using existing predicate data and ISO 10993 testing.
    • Its software underwent verification and validation testing in accordance with FDA guidance, with acceptable results.
    • No clinical studies were needed to support this 510(k) due to the strong similarities in device specifications, intended use, and indications for use with the predicate device.

    In essence, the "study that proves the device meets the acceptance criteria" for this 510(k) submission is the demonstration, through comparison to a predicate and adherence to relevant safety standards, that the new device is as safe and effective as a device already on the market. This is a common pathway for medical device clearances that are not introducing fundamentally new technologies or indications.

    1064 nm: Removal of tattoos for all skin types (Fitzpatrick I-VI) to treat the following tattoo colors: black, brown, green, blue and purple.

    The PicoWay laser system is also indicated for benign pigmented lesions removal for Fitzpatrick Skin Types I-IV.

    The Resolve handpiece (1064 nm) is also indicated for the treatment of acne scars in Fitzpatrick Skin Types II-V.

    The Resolve handpieces (532 nm HE, 532 nm, 1064 nm) are also indicated for treatment of wrinkles in Fitzpatrick Skin Types I-IV

    The Resolve Fusion handpiece (1064 nm) is indicated for the treatment of wrinkles as well as benign pigmented lessons in Fitzpatrick Skin Types I-IV

    The Resolve Fusion handpiece (532 nm) is indicated for the treatment of benign pigmented lesions in Fitzpatrick Skin Types I-IV

    Device Description

    The PicoWay System has been previously cleared (K170597, K162454, K160607, K150326, K142372 and K153527) for tattoo removal and treatment/removal of benign pigmented lesions as well as treatment of acne scars and wrinkles. There are minor modifications to the current system to add four (4) new handpieces, minor system specifications, and new wavelengths. The additional new handpieces will work in the same way as the currently cleared PicoWay handpieces as in they will operate in the same manner as the predicate devices.

    The PicoWay Laser System is a solid-state laser capable of delivering energy at wavelengths of 1064 nm, 532 nm, 730 nm (new) or 785 nm at extremely short duration in the range of 240-500 ps. The laser system contains one 755 nm (Alexandrite) laser head which is used to 'pump' (create) the 1064 nm picosecond wavelength. The 1064 nm wavelength can be frequency-doubled to 532 nm as desired. The outputs of the two lasers are designed to be co-linear on the laser rail so that their beam paths are identical as they exit the laser system. This allows the use of a single delivery system which can output either the 532 nm or 1064 nm wavelengths. The current 785 nm and new 730 nm wavelength contain a Ti:Sapphire laser rod that is pumped with the 532 nm energy. All these energies are delivered through an articulated arm and corresponding handpiece. Currently there are two cleared Resolve handpieces (1064 nm and 532 nm), a 785 nm handpiece and a Zoom handpiece that works on two wavelengths (532 nm and 1064 nm).

    AI/ML Overview

    The provided document is a 510(k) summary for the Candela PicoWay Laser System (K191685). It focuses on adding new handpieces and wavelengths to an already cleared device. This type of submission relies heavily on demonstrating substantial equivalence to a predicate device rather than presenting a de novo clinical study with specific acceptance criteria for a novel AI device.

    Therefore, the document does not contain the information requested regarding acceptance criteria and a study proving a device meets those criteria, as one would expect for an AI/ML medical device. Specifically, it lacks:

    • A table of acceptance criteria and reported device performance for an AI/ML algorithm. The document primarily addresses the safety and performance of laser hardware.
    • Sample size and data provenance for a test set to evaluate an AI/ML algorithm.
    • Details on experts used to establish ground truth or adjudication methods for an AI/ML test set.
    • Information on MRMC comparative effectiveness studies or standalone AI performance.
    • Details on training set sample size or ground truth establishment for an AI/ML algorithm.

    The document primarily discusses:

    • Device Description: The PicoWay Laser System and the new handpieces/wavelengths.
    • Technological Characteristics: Highlighting their similarity to the predicate device.
    • Performance Data (for hardware safety and function):
      • Electrical Safety and Electromagnetic Compatibility
      • Biocompatibility
      • Software (V&V for updated functionality, not an AI algorithm)
      • Bench Testing (for hardware specifications)
      • Ship Testing (for packaging integrity)
    • Clinical Data: Explicitly states, "The PicoWay Laser System did not require clinical performance data." This further confirms the absence of clinical studies evaluating performance against acceptance criteria for an AI solution.

    In summary, the provided text describes a submission for a laser system where the substantial equivalence argument is based on hardware modifications and engineering verification/validation, not on the performance of a new AI algorithm against pre-defined clinical acceptance criteria.

    AI/ML Overview

    The Vbeam Prima Laser System (K183452) is a laser surgical instrument. As stated in section 9, "no clinical studies were needed to support this 510(k) Premarket Notification." Therefore, no specific acceptance criteria or "study that proves the device meets the acceptance criteria" in terms of clinical performance are provided in the document.

    The document focuses on demonstrating substantial equivalence to predicate devices (Candela Vbeam Prima Laser System (K180593) and Candela GentleMAX Family of Pulse Dye Laser Systems (K140122)) through non-clinical performance data.

    Here's a breakdown of the information requested, based on the provided text:

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

    Since no clinical acceptance criteria or performance metrics were reported for this specific 510(k), this table cannot be populated as requested. The document emphasizes equivalence to predicate devices based on:

    Operating Principles Similarity:Same repetition rate, range of spot sizes as predicate.
    Minor Differences in Parameters:Input voltage, pulse duration, and pulse energy are similar to predicates and do not raise new safety or effectiveness questions.

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

    Not applicable, as no clinical human subject test set was used for this 510(k) submission. Performance data primarily comes from engineering and software testing.

    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, as no clinical human subject test set requiring expert ground truth assessment was conducted.

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

    Not applicable, as no clinical human subject test set was conducted.

    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

    Device Description

    The PicoWay Laser System is a solid state laser capable of delivering energy at wavelengths of 1064 nm, 785 nm, or 532 nm at short durations of 240–750 picoseconds (ps) at repetition rates up to 10 Hz (1064 nm, 532 nm) or 5 Hz (785 nm). The device system is comprised of a system console, an articulated arm, and an attached handpiece. The laser output at each wavelength is generated within the laser chassis and delivered to the skin through an articulated arm delivery system terminated by a handpiece. The light-weight and ergonomic handpieces allow the spot size on the skin to be easily adjusted. A range of spot sizes is available for the PicoWay System (up to 10 mm). The system includes an internal calibration port with an internal meter located on the control panel of the system console, which is used to verify the transmission of the articulated arm. The PicoWay system control panel enables the user to select the desired energy density level and repetition rate. The control panel is also used to obtain feedback from the system, such as the number of pulses delivered or spot size selected.

    AI/ML Overview

    The provided text describes the FDA 510(k) summary for the PicoWay Laser System, primarily focusing on its expansion of indications for use to include the treatment of wrinkles.

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

    Device: PicoWay Laser System
    Expanded Indication: Treatment of wrinkles using the Resolve handpieces (532nm or 1064nm wavelengths)

    Acceptance Criteria and Reported Device Performance

    Acceptance Criteria (Primary Endpoint Criterion)Reported Device Performance
    80% of treated areas showing improvement in wrinkles appearance, as assessed by the correct identification of the post-treatment photograph and assessment of at least one Elastosis Score unit.82% of treated areas showed improvement in wrinkles appearance (exceeding the primary endpoint criterion).
    Additional findings:
    • Investigator assessments: 92% improvement rate at 12-week follow-up.
    • Mean elastosis score improvement: 1.44 ± 0.83.
    • Investigator satisfaction rate: 88%.
    • Subjects' satisfaction rate: 74% at the last visit.
    • Very positive safety profile with no adverse events (though 2 subjects reporting severe pain were counted as AEs out of caution, but resolved next day without intervention).
    • Anticipated treatment responses (erythema, edema, tingling, crusting, acne breakout) observed and resolved within days without medical intervention.
    • Most subjects reported low levels of pain during treatment and discomfort in the week following treatment, indicating good tolerability. |

    Study Details:

    1. Sample Size and Data Provenance:

      • Test Set Sample Size: A total of 74 subjects were enrolled, and 72 subjects were treated.
      • Data Provenance: The study was a "multicenter study conducted at 4 sites in the United States." The data is prospective.
    2. Number and Qualifications of Experts for Ground Truth:

      • Number of Experts: Two blinded evaluators.
      • Qualifications: Not explicitly stated beyond "blinded evaluators." It's common in dermatology/cosmetic studies for these to be board-certified dermatologists or plastic surgeons, but the document does not specify.
    3. Adjudication Method for the Test Set:

      • The assessment was performed by "2 blinded evaluators." The text implicitly suggests consensus or independent agreement was sought for the "correct identification of the post treatment photograph and assessment of at least one Elastosis Score unit." However, a formal adjudication process like 2+1 or 3+1 is not explicitly described. It simply states "as assessed by 2 blinded evaluators," implying their combined assessment formed the ground truth for the primary endpoint.
    4. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

      • No MRMC study was conducted for human readers with and without AI assistance. This device is a laser system, not an AI diagnostic tool that assists human readers. The clinical study was a direct evaluation of the device's effect on wrinkles.
    5. Standalone Performance (Algorithm Only):

      • N/A. This is a hardware device (laser system) used for treatment, not an algorithm for diagnosis or image analysis. The "performance" here refers to the clinical efficacy and safety of the physical device.
    6. Type of Ground Truth Used:

      • The ground truth for the primary endpoint was established by expert assessment ("2 blinded evaluators") based on "correct identification of the post treatment photograph and assessment of at least one Elastosis Score unit." This is a subjective, observer-reported outcome measure in a clinical setting.
      • Additional ground truth indicators included investigator assessments, subject satisfaction, and adverse event reporting.
    7. Sample Size for the Training Set:

      • N/A. This is a medical device (laser system), not a machine learning algorithm that requires a separate training set. The study describes a clinical trial evaluating the device's performance directly on human subjects.
    8. How the Ground Truth for the Training Set Was Established:

      • N/A. (See point 7).
