Intended Use

The CoolSculpting System is a skin cooling or heating device. The device is indicated for cold-assisted lipolysis of the 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 the thigh, abdomen and the 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 Gelpad facilitates thermal contact of the device with a patient's skin by mitigating minor variances in device-to-skin contact.

Device Story

Portable thermoelectric cooling/heating system; applies controlled thermal energy to treatment sites via vacuum or surface applicators. Components include control unit, applicators, liners, gelpads, cycle cards, foam borders, and securement system. Operated by clinicians in clinical settings. Device facilitates lipolysis of subcutaneous fat; provides localized thermal therapy; offers optional massage function. Clinicians use device to affect body appearance, manage procedural pain, and treat minor musculoskeletal discomfort. Patient benefits include non-invasive fat reduction and temporary pain/spasm relief. Mechanism of action relies on controlled thermal transfer to target tissues.

Clinical Evidence

Prospective, IRB-approved, non-significant risk study (n=45) evaluated safety/efficacy of flexible treatment parameters on flanks. Primary endpoint: fat layer thickness reduction (ultrasound) met (p<0.0001). Secondary endpoints: photo identification (86% accuracy) and subject satisfaction (88.37% satisfied) met. Safety: adverse events included numbness, pain, hyperpigmentation, and one first-degree burn; all resolved. No new biocompatibility risks identified.

Technological Characteristics

Thermoelectric cooling/heating device. Features vacuum and non-vacuum surface applicators. Materials identical to previously cleared predicates (DEN090002, K120023, K133212). System includes control unit, applicators, and accessories (gelpads, liners).

Indications for Use

Indicated for cold-assisted lipolysis of thigh, abdomen, and flank (love handles) in individuals with BMI ≤ 30; localized thermal therapy for pain relief post-trauma/surgery, minor aches, pains, and muscle spasms; and optional massage for temporary relief of muscle aches/spasms, improved local circulation, and reduced appearance of cellulite. Used to minimize pain/thermal injury during laser/dermatological procedures.

PREDICATE DEVICES: The ZELTIQ CoolSculpting System (DEN090002, K120023, K133212)

# DESCRIPTION OF THE DEVICE SUBJECT TO PREMARKET NOTIFICATION:

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, gelpads, cycle cards, foam borders and securement system.

# SUBSTANTIALLY EQUIVALENT TO:

The ZELTIQ CoolSculpting System is substantially equivalent to the ZELTIQ Dermal Cooling Device, also known as the ZELTIQ CoolSculpting System, which has been cleared for the indication of cold-assisted lipolysis of the flank (love handle) under DEN090002, for the abdomen under K120023, and for the thighs under K133212.

{4}------------------------------------------------

Clinical testing has demonstrated the ability of the CoolSculpting System to cause lipolysis of the subcutaneous fat in the treatment area with flexible treatment parameter ranges in the same way as the predicate device. The mechanism of action remains the same regardless of temperature or treatment duration. The flexible parameters do not raise new issues of safety or effectiveness.

# INDICATION FOR USE:

The CoolSculpting System is a skin cooling or heating device is indicated for cold-assisted lipolysis of the 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 the thigh, abdomen and the 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 Gelpad facilitates thermal contact of the device with a patient's skin by mitigating minor variances in device-to-skin contact.

# TECHNICAL CHARACTERISTICS:

The CoolSculpting System is a thermoelectric cooling and heating device that applies cooling or heating to a treatment site. This system features vacuum applicators of various sizes and a nonvacuum surface applicator that is intended to provide clinicians with an additional option when treating a flat area of the body. The technological characteristics are the predicate devices. All share the same mechanism of cooling and heating for the same intended use.

# PERFORMANCE DATA:

ZELTIQ conducted an IRB-approved non-significant risk clinical study to evaluate the safety and efficacy of the CoolSculpting System with flexible treatment parameter ranges. The study enrolled 45 subjects who received up to two treatments on the flank in one visit. Follow-up was conducted until 16 weeks post-treatment. Subjects were assessed for efficacy via ultrasound and comparison of before and after photographs.

The primary efficacy endpoint of reduction in fat layer thickness was met. Analysis of ultrasound data showed statistical significance (p<0.0001) for both the as-treated population and per-protocol population. The secondary efficacy endpoint of correct identification of pre- vs 16-week post-treatment images was met. The correct photo pair identification rate was 86% for the per-protocol population, with 85% of all photo pairs being correctly identified by at least two out of three reviewers. The secondary efficacy endpoint of subject satisfaction was also met. For the as-treated population, 88.37%

{5}------------------------------------------------

reported being moderately or very satisfied with the CoolSculpting procedure. The primary safety endpoint of device and/or procedure-related adverse events was met. Adverse events included numbness, pain, and hyperpigmentation. One treatment was not completed due to a first degree burn. Three cases of numbness lasted beyond the 16 week follow-up and all three had resolved within 19 days of their respective 16-week visits. All device and/or procedure-related adverse events were mild or moderate in nature and all have resolved.

The materials used in this device are the same as previously cleared in DEN090002, K120023, and K133212. No new biocompatibility risks have been identified.
