| Primary Safety Endpoint: Freedom from serious adverse events attributable to the Cabochon procedure or device for all subjects (100%). | Achieved for all subjects (100%). (Met) |
2. Sample size used for the test set and the data provenance:
- Sample Size: 55 subjects.
- Data Provenance: Prospective, multi-center, non-randomized open-label safety and effectiveness study conducted in 3 US centers.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- The document implies that the ground truth for the primary and powered secondary endpoints (Cellulite Severity Scale and grade improvement) was established by independent physician assessment of subject photographs.
- The document also refers to independent physician assessment for the overall study success criteria, GAIS, and correct selection of photographs.
- The qualifications of these experts are not explicitly stated beyond being "independent physicians."
4. Adjudication method for the test set:
- The document mentions "independent and blinded review of the photographs." While it specifies "independent physician assessment," it does not explicitly state a formal adjudication method like 2+1 or 3+1 for discrepancies in evaluation. It is implied that the assessment contributed to the reported metrics.
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 Cabochon System (a medical device for cellulite treatment) and its effectiveness, not an AI system.
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 Cabochon System is a powered surgical instrument, not an AI algorithm. Its performance was evaluated through clinical trials involving human subjects, physicians, and their assessments.
7. The type of ground truth used:
- The ground truth was based on expert consensus/assessment (independent physician assessment) of subject photographs against established clinical scales (Cellulite Severity Scale, severity grades, Global Aesthetic Improvement Scale). It was observational and subjective assessment by experts.
8. The sample size for the training set:
- Not applicable. The Cabochon System is a physical medical device, not an AI algorithm that requires a training set in the conventional sense. The "training" for the device would involve physician training on its use, but this is not reflected as a data "training set" for an algorithm.
9. How the ground truth for the training set was established:
- Not applicable, as there is no mention of an algorithm or training set in the context of this device's regulatory submission.

Automatic Class III Designation (de novo Petition) for the Cabochon System. Reclassification to Class II (special controls) was supported by the 3 month clinical data from the pivotal study conducted under IDE G120116. The reason for this submission is to request change in indications for use based on 1 year follow-up and independent evaluation of safety and effectiveness in the pivotal study (IDE G120116). These differences are not critical to the intended use of the device and do not affect the safety and effectiveness of the device when used as labeled.
Performance Testing:
Comprehensive bench testing has been successfully completed for the Cabochon System on multiple lots of aged and time-zero product. Testing was performed on finished, sterile devices that were exposed to environmental and transportation conditioning prior to testing which included simulated use, durability and mechanical integrity. All devices were shown to meet predetermined acceptance criteria.
Animal
Bench
Ex vivo and in vivo studies were conducted in the porcine model to verify the performance of the Cabochon System. The ex vivo studies used sections of porcine tissue excised from the sides of Yucatan pigs. The tissue sections were harvested from euthanized pigs and consisted of the dermis, fat, and muscle layers extending down to the rib cage. Verification of the depth of tissue release and the release area was performed in this model.
The in vivo studies were performed on Yucatan pigs under general anesthesia to verify the safety of the release methodology. Treatment with the Cabochon System was performed at different treatment time points prior to euthanasia to investigate the healing response. Findings included that bleeding was minor at all the treatment sites, the plane and areas of tissue release were within specification and the area of release was as expected. There were no necrotic areas noted in the dermis at any time point, as determined by gross and histological evaluation.
Clinical
The safety and effectiveness of the Cabochon System was evaluated in a pivotal clinical study conducted under IDE G120116. A prospective. multi-center, non-randomized open label, safety and effectiveness study with treatment of 55 subjects was conducted in 3 US centers. All subjects served as their own control and underwent a single treatment with the Cabochon
{2}------------------------------------------------
System. All subjects underwent follow-up assessments at 3 days. 14 days. I month. 3 months. 6 months and I vear post treatment. The subject inclusion/exclusion criteria limited inclusion to female subjects between the ages of 18 and 55 with moderate to severe cellulite and BMI less than 35. The subjects were asked to rate their satisfaction with their appearance and pain. Photographs were taken in accordance with a protocol-specific procedure at baseline and each follow-up. An independent and blinded review of the photographs before treatment and at I year was used to verify the effectiveness of the procedure. A DSMB was formed and independently managed to provide safety oversight for the study.
All study endpoints were achieved. The primary safety endpoint, defined as freedom from serious adverse events attributable to the Cabochon procedure or device was achieved for all subjects (100%). The overall study success criteria was met with a clinically significant, long term improvement in the appearance of cellulite in the treated subjects defined by the following:
- . The primary endpoint was met: achievement of ≥1 point average reduction in the 0-5 point Cellulite Severity Scale as determined by independent physician assessment of subject photographs taken before and l year after treatment.
- The average improvement was 2.0 points (p<0.0001) o with the 97.5% confidence limit of a 1.7 point improvement.
- The powered secondary endpoint was met: improvement e of one grade or more in severity (none, mild, moderate, severe) in >60% of treated subjects as determined by independent physician assessment of subject photographs taken before and 1 year after treatment.
- 94.0% of treated subjects had improvement of I grade o with a 95% confidence limit of 85.9%.
All additional secondary measures were also achieved or acceptable:
- . The average rate of correct selection by independent physician assessment of blinded subject photographs taken before and 1 vear after treatment was 99%.
- . 100% of the subjects had noticeable improvement in the Global Aesthetic Improvement Scale GAIS and 72% were characterized as having marked improvement or better by independent physician assessment of blinded subject
{3}------------------------------------------------
photographs taken before and 1 year after treatment.
- . 94% of the subjects were either satisfied or very satisfied as evaluated by a 5 point Likert type scale at the 1 year follow-up.
- . Subject reported pain on a 0-10 numerical rating scale was 4.5 for the delivery of anesthesia and 3.7 for the tissue release portion of the procedure. For the follow-ups, 71% of subjects rated pain ≤ 3 at 3 days, and over 95% rated pain ≤ 3 thereafter. No subjects reported pain at 1 year.
Conclusion:
The (only) purpose of this 510(k) Premarket Notification is for updated labeling of the Cabochon System based on the completion of the 1 year follow-ups from the pivotal study. This clinical data demonstrates that the Cabochon System is both safe and effective for long term improvement in the appearance of cellulite. Based on the design, materials, principle of operation and intended use, the Cabochon System is substantially equivalent to the legally marketed predicate device.
