While the provided text describes the CoolSculpting Elite System, its indications for use, and a 510(k) summary, it does not contain any information about acceptance criteria or a study that proves the device meets those criteria, particularly not for AI/ML-based performance parameters.

The document outlines a traditional 510(k) submission for a software update (including Wi-Fi functionality) and a new S180 applicator for the CoolSculpting Elite System. The primary focus of the performance testing mentioned is to demonstrate equivalence to the predicate device and confirm that the modified system functions as intended, without raising new safety or effectiveness concerns.

The 510(k) summary explicitly states: "The modified CoolSculpting Elite System is identical to the predicate device in terms of principle of operation, mechanical features, performance specifications, software, hardware, algorithm, and treatment workflow." This indicates that there isn't a new AI/ML algorithm being introduced with this submission that would require detailed performance metrics against specific acceptance criteria for AI-driven diagnostic or treatment recommendations. The Wi-Fi functionality is for data transfer (logs, errors, diagnostics) and not for achieving the device's intended use.

Therefore, I cannot fulfill your request for the detailed information about acceptance criteria and a study proving the device meets them, as it pertains to AI/ML performance, because this information is not present in the provided document. The document concerns a hardware and minor software update to an existing device, not the validation of a new AI/ML component.

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

No, a standalone algorithm performance study was not done. The CoolSculpting System is a physical device, and its performance relies on its direct application to the patient, not on an algorithm operating independently without human intervention.

7. The Type of Ground Truth Used

The ground truth used for effectiveness was a combination of:

• Quantitative measurements: Ultrasound measurement, caliper measurement, Magnetic Resonance Imaging (MRI), and three-dimensional (3D) quantification of volume reduction.
• Expert assessment: Blinded, independent review of clinical photographs (implicitly by experts).
• Patient-reported outcomes: Patient satisfaction.
• Clinical observation/Adverse Event reporting: For safety outcomes.

8. The Sample Size for the Training Set

The document does not describe a "training set" in the context of an algorithm or AI. The CoolSculpting System is a physical device.

• Sample Size for Effectiveness Analysis: 57 subjects (per-protocol population of an original IDE study, with one exclusion due to excessive hair).
• Data Provenance: The study was a retrospective photo analysis of data from an original IDE approved study. While the country of origin isn't explicitly stated, the context of FDA submission suggests a US-based study or one adhering to US regulatory standards.

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

• For the "original IDE study" (K151179): An "independent panel reviewers" performed photographic identification. The number and specific qualifications of these reviewers are not explicitly stated in this document.
• For the "retrospective photo analysis" of lax tissue: The photographic analysis involved:
  • One board-certified plastic surgeon who identified anatomical points and performed measurements.
  • A "physician panel" (presumably the same "independent panel reviewers" from the original IDE study, but not explicitly confirmed) who reviewed photographs for a visible response. The number and specific qualifications of this panel are not explicitly stated in this document beyond being "physician."

4. Adjudication Method for the Test Set

• For the original IDE study's primary effectiveness endpoint (photographic identification): It was a review by an "independent panel reviewers." No specific adjudication method (e.g., 2+1) is mentioned, only that a "correct baseline photograph identification rate" was reported.
• For the retrospective photo analysis (lax tissue appearance):
  • A single board-certified plastic surgeon performed the quantitative measurements (≥ 20 mm² decrease). This wasn't an adjudication but a direct measurement by an expert.
  • A "physician panel" retrospectively evaluated visible response, and their agreement (or lack thereof) with the quantitative findings was noted. The exact adjudication method used by this panel is not specified.

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

The "performance data" section mentions "Software Verification and Validation Testing" but states it's the same as a previously cleared predicate device and does not involve AI for diagnostic purposes.

7. The Type of Ground Truth Used

• Expert Consensus/Measurement:
  • For the original IDE study's primary effectiveness endpoint, the ground truth was based on the "correct baseline photograph identification" by independent panel reviewers.
  • For the retrospective study on lax tissue, the primary measure of effectiveness (>20 mm² reduction) was derived from measurements performed by a board-certified plastic surgeon on anatomical points. This was then corroborated by an "independent physician review panel" confirming a "visible response."
• Subject Reported Outcomes: For the secondary effectiveness endpoint in the original IDE study, subject satisfaction (agreement that the treatment made their chin look more toned) served as a ground truth measure.

8. The Sample Size for the Training Set

• Not applicable / Not specified. This submission is for an updated indication for a physical medical device. There is no mention of a "training set" in the context of an AI algorithm learning from data. The effectiveness study relies on an independent panel review and expert measurement on a test set, not on a machine learning model trained on a separate dataset. The "original IDE approved study" involved 60 enrolled subjects, but this served as the source for the test set for the retrospective analysis, not a training set.

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

• Not applicable. As there is no training set for an AI algorithm mentioned in this document, the method for establishing its ground truth is not relevant. The ground truth for the test set was established as described in point 7.

Ask a specific question about this device

The CoolSculpting System is a skin cooling or heating device is indicated for cold-assisted lipolysis (breakdown of fat) of the upper arm, bra fat, banana roll, submental area, thigh, abdomen, and flank, or "love handles" 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 upper arm, bra fat, banana roll, submental area, thigh, abdomen and flank.

Cooling with the device may also be used to minimize pain and thermal injury during laser and dermatological treatments and act as a local anesthetic for procedures that induce minor local discomfort.

The CoolSculpting System is also indicated for use to provide localized thermal therapy (hot or cold) to minimize pain post-trauma and post-surgery, and for temporary relief of minor aches, pains, and muscle spasms. The optional massage function can also be used for the temporary relief of minor muscle aches, pain, and spasm and for temporary improvement in local circulation and temporary reduction in the appearance of cellulite.

The ZELTIQ Pretreatment Skin Wipe and Gel/Gelpad facilitate thermal contact of the device with a patient's skin by mitigating minor variances in device-to-skin contact.

The CoolSculpting System is a portable thermoelectric cooling and heating device that applies controlled cooling or heating to a treatment site. The CoolSculpting System is comprised of a control unit, detachable vacuum and surface applicators and supplies such as liners, gel/gelpads, cycle cards, geltraps, gaskets, foam borders and securement system.

As part of the CoolSculpting System suite of applicators, ZELTIQ has developed two new vacuum applicators known as CoolAdvantage Plus and CoolAdvantage Petite. Both applicators feature the curved aluminum cup design with interchangeable silicone contours that is identical to the previously cleared CoolAdvantage applicator (K162050). They have been modified in size to accommodate different sizes of fat bulges. All other technological characteristics, including mechanism of action, and performance remain identical for the CoolAdvantage family of applicators.

The CoolAdvantage family of applicators is also provided with a new gelpad known as CoolAdhesive Pad. The CoolAdhesive Pad is comprised of fructose and glycerin in a pad made of rayon and spandex. This material is commonly used in the garment industry. It has the identical functionality as the previously cleared gelpads and is intended to provide consistent thermal contact during treatments with the CoolAdvantage family of applicators. Fructose and glycerin are considered safe ingredients and are found in commonly used products. Fructose is generally used as a food additive and glycerin is typically found in common cosmetic products such as lotion and soap. Glycerin is generally recognized as safe (GRAS per CFR §182.1320). The CoolAdhesive Pad has been tested for biocompatibility and is considered biocompatible. The performance remains the same for CoolAdhesive Pad as for the previously cleared gelpads.

The provided text describes the 510(k) summary for the ZELTIQ CoolSculpting System, specifically focusing on the introduction of two new applicators (CoolAdvantage Plus and CoolAdvantage Petite) and a new gelpad (CoolAdhesive Pad). The document explicitly states that no clinical studies were performed in support of this specific submission. Therefore, it is impossible to provide information regarding a study that proves the device meets acceptance criteria based on the provided text alone, as such a study was not part of this submission process.

The FDA's decision of substantial equivalence (K171069) for this device relies heavily on its similarity to a previously cleared predicate device (ZELTIQ CoolSculpting System, K162050), which presumably underwent clinical testing for its initial clearance or was cleared through other pathways.

However, based on the information provided, I can construct parts of the answer regarding acceptance criteria and the types of testing performed for this specific submission, even though they do not involve clinical performance data.

Here's an analysis of the provided text in relation to your questions, highlighting where information is absent due to the lack of clinical studies in this specific submission:

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

The document details various tests conducted and generally states that the device "passed successfully by meeting the acceptance criteria." Specific numerical performance data or detailed acceptance criteria from these tests are not provided in this summary.

Acceptance Criteria and Reported Device Performance (Based on provided text, non-clinical):

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

• Sample Size for Test Set: Not applicable for clinical performance as "no preclinical or clinical testing was performed" for this specific submission. For bench testing, sample sizes are not explicitly mentioned.
• Data Provenance: Not applicable for clinical performance. For bench testing, the data origin is from ZELTIQ Aesthetics, Inc.'s internal testing.

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

• Not applicable. As no clinical performance study was conducted for this submission, there was no ground truth established by experts in the context of clinical efficacy or safety.

4. Adjudication method for the test set

• Not applicable. No clinical test set.

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. No clinical studies, let alone MRMC studies, were performed or described for this specific submission. The device is a physical system for aesthetic treatment, not an AI-assisted diagnostic tool.

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

• Not applicable. The device is a physical system, not an algorithm. Bench testing demonstrated the device's technical performance in a standalone manner (without patient interaction) against specifications.

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

• Not applicable for clinical ground truth. For the non-clinical performance and safety data:
  • Biocompatibility: Ground truth is established by the specified ISO 10993 standards and their inherent scientific principles for evaluating biological compatibility.
  • Electrical Safety & EMC: Ground truth is defined by the requirements of IEC 60601-1 and IEC 60601-1-2 standards.
  • Software V&V: Ground truth is adherence to the "General Principles of Software Validation" guidance and internal software requirements.
  • Bench Performance: Ground truth is defined by the internal design specifications and defined performance parameters of the device.

8. The sample size for the training set

• Not applicable. The device is not an AI/ML model that requires a training set in the typical sense.

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

• Not applicable.

Summary of Device Performance Assessment in this Submission:

The ZELTIQ CoolSculpting System's K171069 submission primarily focuses on demonstrating substantial equivalence to its predicate device (K162050) by highlighting that the new applicators and gelpad maintain the same indications for use, mechanism of action, and performance characteristics. The acceptance criteria for this specific submission were met through:

• Biocompatibility testing of the new gelpad.
• Electrical safety and EMC testing of the overall system.
• Software verification and validation (since the software remained unchanged from the predicate, ensuring its continued proper function).
• Bench performance testing to ensure the new applicators and gelpad performed as expected and within previously cleared parameters (e.g., maintaining the target temperature, durability, etc.).

The key takeaway is that for this 510(k) submission, the "study that proves the device meets the acceptance criteria" refers to the non-clinical performance and safety testing outlined, rather than a clinical trial with human subjects. The substantial equivalence argument negates the need for new clinical data if the technological characteristics are sufficiently similar and safety/performance are demonstrated through non-clinical means.
