Cynosure SculpSure is a diode laser system intended for non-invasive lipolysis of the abdomen and flanks in individuals with a Body Mass Index (BMI) of 30 or less. The device is intended to affect the appearance of visible fat bulges in the abdomen and flanks.
The Cynosure SculpSure is a diode laser system. The main components of SculpSure are a console and four applicators that deliver the laser energy to the patient. Electrically efficient semiconductors generate optical radiation (1060 nm) which is used to deliver laser energy to subcutaneous tissue layers.
This document is a 510(k) summary for the Cynosure SculpSure device, which is a diode laser system intended for non-invasive lipolysis. It focuses on demonstrating substantial equivalence to predicate devices rather than proving specific acceptance criteria through a dedicated study with performance metrics. Therefore, many of the requested details about acceptance criteria, detailed study design, and performance metrics are not explicitly available in this document.
However, based on the information provided, here's what can be extracted and inferred:
1. Table of Acceptance Criteria and Reported Device Performance:
The document does not explicitly present a table of acceptance criteria with numerical performance data for specific clinical outcomes. The clinical performance is described in terms of "affecting the appearance of visible fat bulges."
| Acceptance Criteria (Implied) | Reported Device Performance (Implied) |
|---|---|
| Non-invasive lipolysis of abdomen and flanks | Intended to affect the appearance of visible fat bulges in the abdomen and flanks. |
| Safety within specified operating parameters | Non-clinical tests (electrical safety, EMC, biocompatibility) confirm safety standards are met. |
| Functionality as intended | Software verification and validation confirm software performs as intended. Power output meets specification. |
2. Sample Size Used for the Test Set and Data Provenance:
- Test Set Sample Size: "Not applicable, no change in indication for use." This implies that the current 510(k) submission did not include a new clinical test set to prove device efficacy for the stated indications. Instead, it relies on the previous approvals of its predicate devices.
- Data Provenance: Not applicable for a new clinical test set in this submission. The original predicate devices' approvals would have contained this information. It is not mentioned whether any retrospective or prospective data was used for this specific submission beyond the predicate device references.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications:
- Not applicable as no new clinical test set was submitted for this 510(k) for evaluating efficacy.
4. Adjudication Method for the Test Set:
- Not applicable as no new clinical test set was submitted for this 510(k).
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:
- No MRMC comparative effectiveness study is mentioned in this 510(k) summary. The submission focuses on substantial equivalence based on technological characteristics and safety, not on comparative effectiveness with human readers.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:
- The SculpSure device is a physical laser system, not an AI algorithm. Therefore, the concept of "standalone (algorithm only)" performance is not applicable in this context. The device's performance is inherently linked to its physical output and application by a user.
7. The Type of Ground Truth Used:
- For the intended use of "affecting the appearance of visible fat bulges," the ground truth in previous studies for the predicate devices (or the original SculpSure K150230) would likely have involved clinical assessment of fat reduction (e.g., circumferences, caliper measurements, imaging such as ultrasound or MRI, and potentially patient/physician satisfaction surveys). However, this specific 510(k) does not detail new efficacy studies.
- For non-clinical tests:
- Software verification and validation: Ground truth is the predefined functional requirements and specifications of the software.
- Power output testing: Ground truth is the specified power output range.
- Biocompatibility: Ground truth is ISO 10993-1 standards.
- Electrical safety and EMC: Ground truth is the specified international standards (e.g., IEC 60601-1).
8. The Sample Size for the Training Set:
- Not applicable as this 510(k) is not for an AI/algorithm-based device that requires a training set in the typical machine learning sense. The device is a physical laser system.
9. How the Ground Truth for the Training Set Was Established:
- Not applicable for the same reason as point 8.
Summary of the Study that Proves Device Meets Acceptance Criteria (based on the provided document):
The provided document (K160470) is an administrative change to a previous 510(k) and refers back to the original substantial equivalence determination for SculpSure (K150724 and K150230). This specific submission does not contain new clinical studies to prove efficacy. Instead, it relies on demonstrating substantial equivalence to its own previously cleared versions and other predicate devices, citing "no change in indication for use."
The "studies" that support the device meeting acceptance criteria (in terms of safety and performance for its intended use) are:
- Non-clinical tests:
- Software verification and validation.
- Power output testing.
- Electromagnetic compatibility (EMC) and electrical safety testing (per IEC 60601-1, IEC 60601-1-2, IEC 60601-2-22, IEC 60825-1).
- Biocompatibility assessment (per ISO 10993-1).
These non-clinical tests aimed to ensure the device's technical specifications, safety, and compatibility were met, demonstrating that the device "should perform as intended in the specified use conditions." The efficacy for "non-invasive lipolysis of the abdomen and flanks" was established in the earlier 510(k) submissions for the predicate SculpSure devices.

- Number of Experts: Three blinded evaluators.
- Qualifications of Experts: Board-certified dermatologists.
4. Adjudication Method for the Test Set
- The photographic evaluations were performed individually by three blinded evaluators. The text states, "In 95% of the total individual evaluations the evaluators correctly identified the before and after images." This suggests that the performance was aggregated from individual assessments, but it does not specify a formal adjudication method like a 2+1 or 3+1 consensus. It seems each individual expert's correct identification contributed to the overall 95% figure.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study focusing on human readers improving with AI vs. without AI assistance was not done. This study focused on the effectiveness of the device itself, with experts evaluating photographic outcomes as a primary endpoint.
6. Standalone (Algorithm Only) Performance
- No, a standalone (algorithm only) performance study was not explicitly mentioned or performed as described. The primary endpoint involved human evaluators (dermatologists) assessing photographs. The device itself is a laser system, not an AI diagnostic algorithm.
7. Type of Ground Truth Used
- Expert Consensus/Opinion: For the primary endpoint (photographic evaluation), the ground truth was established by the agreement of board-certified dermatologists on the correct identification of before and after images, implying visual assessment of aesthetic improvement.
- Quantitative Measurement: For the secondary and tertiary endpoints, objective measurements were used:
- Ultrasound Measurements: To determine the change in adipose layer thickness.
- Subject Satisfaction Survey: To gauge patient perception of outcome.

- A table of acceptance criteria and the reported device performance: The document does not specify quantitative acceptance criteria for clinical performance (e.g., specific percentages of wrinkle reduction, hair removal efficacy, or lesion clearance) or report device performance against such criteria.
- Sample size and data provenance for the test set: No clinical test set is described.
- Number and qualifications of experts for ground truth: No ground truth establishment related to clinical outcomes is mentioned.
- Adjudication method: Not applicable as no clinical test set/ground truth is described.
- MRMC comparative effectiveness study: No such study is mentioned. The device is a laser system, not an AI-assisted diagnostic tool.
- Standalone performance: The document deals with a physical medical device, not a standalone algorithm.
- Type of ground truth used: Not applicable as no clinical endpoints are being evaluated against a ground truth.
- Sample size for the training set: No training set for an algorithm is described.
- How ground truth for the training set was established: Not applicable.
The document does include the following relevant information:
- Nonclinical tests submitted: Sterilization Validation.
- Conclusions drawn from non-clinical data: An Autoclave Sterilization Validation of the 10 x 10 and 6 x 6 Focal Guide Assemblies was conducted. The test articles, negative controls, and environmental controls all exhibited no growth of G. stearothermophilus after being subjected to 3 half cycle rounds of specific gravity cycle settings, meeting an SAL of ≤10⁻⁶. Functional testing showed that the sterilization did not affect device function. This indicates the device meets sterilization efficacy standards.
In summary, this document is a regulatory submission for substantial equivalence based on technological similarity and non-clinical safety (sterilization). It does not present a clinical study with acceptance criteria for performance related to its intended aesthetic and dermatological uses.

The PicoSure™ workstation is indicated for tattoo and benign pigmented lesions removal. The PicoSure™ workstation with the 3mm and 6mm hand pieces and the Focus Array are indicated for the treatment of acne scars and wrinkles in Skin Types I-IV.
The PicoSure™ workstation is a high powered Alexandrite system that delivers laser energy in the 755-nm wavelength. The system consists of a console that houses the power supply, control electronics and the laser. Laser energy is delivered to the skin via an articulated arm. The laser is activated using a footswitch.
The provided text describes the Cynosure Picosure™ Workstation and its indications for use. It includes a summary of clinical study findings related to the device.
Here's an analysis of the acceptance criteria and the study that proves the device meets them:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Correct identification of post-treatment photograph in 80% or greater of subjects. | The three blinded evaluators correctly identified the "before" and "after" images in 91% of the 38 subjects who returned for 4-month evaluation. This meets the 80% or greater criterion. |
| Fitzpatrick Wrinkle Severity Scale (FWSS) improvement score of "1" or greater at four months. | The mean improvement score using the Fitzpatrick Wrinkle Severity Scale at four months was 1.2. This meets the "1" or greater criterion. |
| No deaths, serious adverse events (SAEs), or unanticipated adverse device effects (UADEs). | No deaths, serious adverse events (SAEs), or unanticipated adverse device effects (UADEs) were reported in this study. The events that were logged were typical reactions to laser treatments. This criterion was met. |
2. Sample size used for the test set and the data provenance
- Sample Size for the Test Set:
- The study included 40 subjects.
- 38 subjects returned for the 4-month evaluation, which is the test set for the photo and FWSS evaluations.
- Data Provenance: The document does not specify the country of origin. The study was conducted as a prospective clinical trial, as evidenced by "before and after" evaluations and follow-up at 4 months post-treatment.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: Three blinded evaluators were used.
- Qualifications of Experts: The document does not specify the qualifications of these evaluators (e.g., dermatologists, plastic surgeons, years of experience).
4. Adjudication method for the test set
- The document implies a consensus or independent evaluation method, as it states "three blinded evaluators, who were able to identify correctly the before and after images in 91% of the 38 subjects." It doesn't explicitly state an adjudication method like 2+1 or 3+1 for discrepancies, but given the high agreement (91%), it might not have been a significant issue or simply not detailed in this summary. It appears each evaluator made an independent judgment, and the percentage reflects the overall agreement across all three for the majority of cases.
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 involving AI assistance was not done. The study evaluated the effectiveness of the laser device itself, with human evaluators assessing the outcome of the treatment without AI assistance.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
- No, a standalone algorithm-only performance study was not done. The primary focus was on the efficacy of the Picosure™ Workstation when applied to human subjects, with human evaluators determining the success of the treatment.
7. The type of ground truth used
- The ground truth for the effectiveness of the treatment was established by expert assessment of photographs (for correct identification of before/after images) and the Fitzpatrick Wrinkle Severity Scale (FWSS) scores, also assessed by experts, indicating a clinical improvement. Safety ground truth was based on reported adverse events.
8. The sample size for the training set
- This document describes a clinical study to demonstrate the effectiveness of the medical device as a treatment. It is not describing the development or validation of an AI algorithm, so there is no mention of a training set in the context of machine learning. The "training set" for the device's efficacy would be considered the prior research and development that led to the device's design, but this is not a data set in the AI sense.
9. How the ground truth for the training set was established
- As there is no AI algorithm being described, there is no training set ground truth in the context of an AI algorithm. The device's "ground truth" for its intended performance is based on the underlying scientific principles of laser-tissue interaction and prior clinical research on similar technologies, not on a labeled dataset for an algorithm.

755 nm:
The Cynosure Elite+ Laser is indicated for stable long-term, or permanent hair reduction. Permanent hair reduction is defined as long-term stable reduction in the number of hairs regrowting when measured 6, 9, or 12 months after the completion of a treatment regime. It is used for all skin types (Fitzpatrick I-VI) including tanned skin. It is also indicated for the treatment of vascular lesions, benign pigmented lesions, and wrinkles.
1064 nm:
The Cynosure Elite+ Laser is intended for the coagulation and hemostasis of benign vascular lesions such as, but not limited to, port wine stains, hemangiomas, warts, telangectasia, rosacea, venus lake, leg veins, spider veins and poikiloderma of civatte; and treatment of benign cutaneous lesions such as warts, scars, striae and psoriasis. The laser is also intended for the treatment of benign pigmented lesions such as, but not limited to, lentigos (age spots), solar lentigos (sun spots), cafe au lait macules, sebortheic keratoses, nevi, chloasma, verrucae, skin tags, keratosis and plaques. The laser is also indicated for the treatment of wrinkles such as, but not limited to, periocular and perioral wrinkles. Additionally, the laser is indicated for the treatment of pseudofolliculitis barbae (PFB) and for stable long-term, or permanent hair reduction. Permanent hair reduction is defined as long-term stable reduction in the number of hairs regrowing when measured at 6, 9 and 12 months after the completion of a treatment regime.
Cynosure Elite+ laser has an Alexandrite crystal rod as the lasing medium, with a wavelength of 755 nm. The 1064 nm wavelength is generated from the Nd:YAG laser head.
Laser activation is by either by finger or foot switch. The overall weight of the laser is 180 lbs and the size is 41 x 15 x 25 in (HxWxD).
Electrical equipment is 208/240 VAC, single phase, 30A, 50/60 Hz.
The modifications to this device are four handpieces allowing for a larger treatment area; 18 mm, 20 mm, 22 mm and 24 mm. The 1064 Nd:YAG laser did not require any modifications to support the new handpieces. Minor modifications, including rod diameter change and lamp fill pressure change, were made to the Alexandrite laser to increase the energy to support the larger spot sizes. The software continues to control the energy based on the handpiece attached. This prevents the increase in available energy from the laser from increasing the fluence of the existing spot sizes.
This document is a 510(k) premarket notification for the Cynosure Elite+ Laser, seeking clearance for a modified device. It focuses on demonstrating substantial equivalence to a predicate device, not on presenting novel clinical study data to prove the device meets specific acceptance criteria in a clinical setting.
Therefore, the requested information regarding acceptance criteria and a study proving the device meets those criteria, specifically concerning clinical performance metrics, cannot be fully extracted from this document in the way it would be for a direct clinical performance study.
However, based on the provided text, I can infer the acceptance criteria relate to the engineering and software performance specifications and that the study proving acceptance was non-clinical testing.
Here's what can be extracted and inferred:
1. A table of acceptance criteria and the reported device performance
| Acceptance Criteria (Inferred from predicate device specifications) | Reported Device Performance (Elite+ K141425) |
|---|---|
| Laser Type: Alexandrite and Nd:YAG Lasers | Alexandrite and Nd:YAG Lasers |
| Wavelength: 755 nm & 1064 nm | 755 nm & 1064 nm |
| Maximum Fluence (755nm): 60 J/cm² | 60 J/cm² |
| Maximum Fluence (1064nm): 300 J/cm² | 300 J/cm² |
| Repetition Rate (755nm): 1 to 5 Hz | 1 to 5 Hz |
| Repetition Rate (1064nm): 1 to 10 Hz | 1 to 10 Hz |
| Pulse Duration: 0.1-300 ms | 0.1-300 ms |
| Spot Sizes (mm): (Predicate: 3, 5, 7, 10, 12.5, 15) | 3, 5, 7, 10, 12, 15, 18, 20, 22, 24 (The key modification) |
| Software Functionality: Meet software specifications | Testing confirmed that the software specifications were met. |
| Overall Performance: Device performs within the same specifications of the predicate device | Testing confirmed the performance of the Elite+ Laser meets the product system requirements, which is based on the predicate device. |
Important Note: The "acceptance criteria" here are engineering and operational parameters demonstrating equivalence to the predicate device, not clinical efficacy or safety endpoints for the expanded spot sizes. The document explicitly states "None" for clinical tests submitted.
The Study that Proves the Device Meets the Acceptance Criteria:
The document describes non-clinical tests as the study proving the device meets its performance requirements.
2. Sample size used for the test set and the data provenance:
- Sample Size: Not specified. As this was non-clinical engineering and software testing, the "sample size" would refer to the number of devices or test cycles, which is not detailed.
- Data Provenance: Not specified, but it would be internal testing conducted by Cynosure Incorporated.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable as this was non-clinical engineering and software testing. Ground truth was established by engineering specifications and direct measurement/validation against those specifications.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable as this was non-clinical engineering and software testing. Adjudication methods are typically for human interpretation in clinical studies.
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 device is a laser system, not an AI-assisted diagnostic tool for human readers.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- Not applicable. This is a medical laser system, not an algorithm. The "standalone" performance here refers to the laser's physical and software operation, which was tested non-clinically.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For the non-clinical tests, the ground truth was based on engineering specifications, direct physical measurements, and software requirement validations.
8. The sample size for the training set:
- Not applicable. This device is a laser system, not an algorithm that requires a "training set" in the context of machine learning.
9. How the ground truth for the training set was established:
- Not applicable for the reason above.

The PicoSure™ workstation is a high-powered, Q-switched Alexandrite system that delivers laser energy in the 755-nm wavelength. The system consists of a console that houses the power supply, control electronics and the laser. Laser energy is delivered to the skin via an articulated arm. The laser is activated using a footswitch.
The provided document describes the PicoSure™ Workstation, a laser system indicated for tattoo and benign pigmented lesion removal, and for the treatment of acne scars when operating with specific handpieces and the FOCUS lens array. The document presents two clinical studies to support the safety and effectiveness of the device for acne scar treatment. Below is an analysis of the acceptance criteria and study data based on the provided text.
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria / Performance Metric | Reported Device Performance (Acne Scars Study) |
|---|---|
| Efficacy - Improvement in Acne Scars | Mean Improvement Score (scale 0-3): 1.9 |
| Evaluator Identification Rate | Blinded Evaluators' Correct Identification of Before/After Photos: 70% of 17 subjects |
| Physician Satisfaction Rate | Non-blinded Treating Physician Overall Satisfaction: 100% (47% "satisfied", 53% "extremely satisfied") |
| Subject Satisfaction Rate | Subjects' Overall Satisfaction: 87% (53% "satisfied", 27% "extremely satisfied") |
| Safety - Tissue Response | - Immediate Post-treatment: Focal epidermal vacuolization and small foci of degenerated keratinocytes. - 7 and 15 Days Post-treatment: Intact epidermis with mild, superficial dermal lymphocytic infiltrates in peri-vascular pattern. (This indicates localized and transient tissue response, which is generally acceptable for laser procedures.) |
Note: The document does not explicitly state pre-defined acceptance criteria values for these metrics. The reported performance implies these results were considered sufficient to demonstrate substantial equivalence.
2. Sample Size and Data Provenance for the Test Set
-
Acne Scars Study (Clinical Study 1):
- Sample Size (Test Set): 17 patients completed the study, with a total of 46 acne scars treated.
- Data Provenance: The document does not explicitly state the country of origin. It is a prospective clinical study, as it describes treatment and follow-up observations.
-
Tissue Response Study (Clinical Study 2):
- Sample Size (Test Set): 3 subjects (2 on arm, 1 on leg).
- Data Provenance: The document does not explicitly state the country of origin. It is a prospective clinical study, as it describes treatment and subsequent biopsies.
3. Number of Experts and Qualifications for Ground Truth (Test Set)
-
Acne Scars Study:
- Number of Experts: Three blinded evaluators.
- Qualifications: The specific qualifications (e.g., radiologist, years of experience) of these evaluators are not specified in the provided text. They were described as "blinded evaluators."
-
Tissue Response Study:
- Number of Experts: Not explicitly stated for establishing ground truth from biopsies, but biopsies would typically be analyzed by pathologists.
- Qualifications: Not specified.
4. Adjudication Method for the Test Set
- Acne Scars Study: The method for reaching consensus among the three blinded evaluators regarding the "before and after images" or for determining the "mean improvement score" is not explicitly detailed. It can be inferred that their evaluations were aggregated, but the specific adjudication (e.g., voting, expert consensus meeting) is not described.
- Tissue Response Study: For the biopsy analysis, an adjudication method is not detailed. Typically, a qualified pathologist would interpret the biopsies, and potentially a second opinion might be sought for complex cases, but this is not mentioned.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- A formal MRMC comparative effectiveness study, comparing human readers with AI assistance versus without AI assistance, was not performed, nor is it applicable to this device. The PicoSure Workstation is a laser device, not an AI diagnostic or assistance tool for human readers. The study involved human evaluators assessing photographic outcomes of a treatment device.
6. Standalone Performance
- A standalone (algorithm only without human-in-the-loop performance) study was not applicable and therefore not conducted. The PicoSure Workstation is a physical laser device used for treatment, not a standalone AI algorithm.
7. Type of Ground Truth Used
- Acne Scars Study: The ground truth for effectiveness was based on:
- Expert Consensus/Opinion: Evaluations by three blinded evaluators of before/after photographs.
- Subjective Satisfaction: Non-blinded treating physician's satisfaction scores and subjects' self-reported satisfaction.
- Tissue Response Study: The ground truth for safety (tissue response) was based on Pathology via biopsies taken at various time points after treatment.
8. Sample Size for the Training Set
- The document describes clinical studies used to assess the performance of the device, not to train an AI algorithm. Therefore, a "training set" in the context of machine learning is not applicable to this device and its studies. The clinical studies served as validation for the device's efficacy and safety.
9. How the Ground Truth for the Training Set Was Established
- As a training set for an AI algorithm is not applicable, the method for establishing its ground truth is not relevant to the information provided. The "ground truth" discussed in the context of these studies refers to the outcomes measured in the clinical trials themselves by evaluators, physicians, and pathological examination.
