In addition, the device is intended for cold-assisted lipolysis of the submental and submandibular areas in individuals with a BMI up to 46.2. The device is intended to affect the appearance of visible fat bulges in the upper arm, bra fat, back fat, banana roll, submandibular areas, thigh, abdomen and flank. When used for cold-assisted lipolysis of the submental area, the device can also affect the appearance of lax tissue in the submental area. Cooling with the device may also be used to minimize pain and thermal injury during laser and dermatoms 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 spassne. 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. ## Device Story Portable thermoelectric cooling/heating system; applies controlled thermal energy to treatment sites. Comprised of control unit, detachable vacuum/surface applicators, and accessories (liners, gel/gelpads, cycle cards, geltraps, gaskets, foam borders). Used in clinical settings by trained operators. Facilitates cryolipolysis for fat reduction and thermal therapy for pain/muscle relief. Input: manual selection of treatment parameters; Output: controlled thermal application to skin. Affects appearance of fat bulges and lax tissue; provides temporary relief of minor aches/pains/spasms. Benefits include non-surgical fat reduction and localized pain management. ## Clinical Evidence Literature review of 228 cryolipolysis treatment cycles in submental/submandibular areas (BMI 22.8–46.2).

DEVICE DESCRIPTION: 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. ### V. INDICATIONS FOR USE: 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, back fat, banana roll, thigh, abdomen, and flank, or "love handles" in individuals with a Body Mass Index (BMI) of 30 or less. In addition, the device is intended for cold-assisted lipolysis of the submental and submandibular areas in individuals with a BMI up to 46.2. The device is intended to affect the appearance of visible fat bulges in the upper arm, bra fat, back fat, banana roll, submentibular areas, thigh, abdomen and flank. When {4}------------------------------------------------ used for cold-assisted lipolysis of the submental area, the device can also affect the appearance of lax tissue in the submental area. 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. # VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE: The ZELTIQ CoolSculpting System is the same as the device cleared in K172144. No changes have been made to the device to accommodate the indication of the submandibular area or clarification of BMI. The CoolSculpting System has been established as safe and effective through many prior clearances (the most recent is K172144). # VII. PERFORMANCE DATA: ### Biocompatibility testing The ZELTIQ CoolSculpting System is the same as the previously cleared predicate device (K172144). # Electrical safety and electromagnetic compatibility (EMC) The ZELTIQ CoolSculpting System is the previously cleared predicate device (K172144). ### Software Verification and Validation Testing The ZELTIQ CoolSculpting System is the previously cleared predicate device (K172144). ### Performance testing The ZELTIQ CoolSculpting System is the same as the previously cleared predicate device (K172144). {5}------------------------------------------------ ## Clinical Performance Data: Clinical publications demonstrated the safety and effectiveness of the CoolSculpting System for treatment of the submandibular area. A review of published literature and clinical studies revealed 228 cryolipolysis treatment cycles during clinical studies of the submental and submandibular areas in a population with a BMI ranging from 22.8 to 46.2. Effectiveness was measured by several techniques including ultrasound measurement, caliper measurement, Magnetic Resonance Imaging (MRI), three-dimensional (3D) quantification of volume reduction, patient satisfaction, and blinded, independent review of clinical photographs. The mean ultrasound measurement of fat layer reduction was 2.4 mm with a range from 2.0 to 2.8 mm. The mean caliper measurement of fat layer reduction was 3.17 mm (around 33%) with a range from 2.3 to 4.0 mm. The single study using MRI imaging showed mean reduction of 17% subcutaneous fat layer reduction. The 3D imaging showed a mean calculated reduction of 8.5 mL fat volume, and calculated reduction in submental laxity by 2.25 mm (Li, DaSilva, Canfield, & McDaniel, Use of 3-Dimensional Imaging in Submental Fat Reduction After Cryolipolysis, 2018). Three-dimensional volumetric measurement showed a fat reduction of 4.82 cm³ (Bernstein & Bloom, 2017). Blinded, independent photo review was conducted in several studies with correct identification of baseline photographs ranging from 60% to 91% averaging 77%. Patient satisfaction ranged from 80% to 93% averaging 85%. There were no procedure or device related serious adverse events reported. Common procedural side effects were transient and resolved without long term effect. The clinical study literature indicates that cryolipolysis is a safe and effective non-surgical procedure for subcutaneous fat reduction in the submental and submandibular areas. Clinical literature review and post-market data have demonstrated the same low-risk safety profile. The published data provided in this submission clearly demonstrate the safety and effectiveness profile of the CoolSculpting System for the indication of treatment of the submandibular and submental areas in a population with a BMI ranging from 22.8 to 46.2. # VIII. CONCLUSION: The ZELTIQ CoolSculpting System is the same as the device cleared in K172144. No changes have been made to the device to accommodate this indication of cold-assisted lipolysis in the submandibular area and clarification of BMI in this patient population. The CoolSculpting System is substantially equivalent to the predicate device for this new indication for use. The clinical data shows results from cryolipolysis in the submandibular area meeting both the safety and effectiveness endpoints. The CoolSculpting System has been established as safe and effective through many prior clearances (the most recent is K172144). The CoolSculpting System has not been changed to accommodate this expanded indication for treatment of the submandibular area and increased BMI for submental and submandibular patients. The {6}------------------------------------------------ clinical data indicates the same safety and effectiveness for the CoolSculpting System for this expanded indications for use for the submandibular area and increased BMI for submental and submandibular treatments. As such, the CoolSculpting System is substantially equivalent to the predicate device (previously cleared CoolSculpting System, K172144). --- **Source:** [https://fda.innolitics.com/submissions/SU/subpart-e%E2%80%94surgical-devices/OOK/K181740](https://fda.innolitics.com/submissions/SU/subpart-e%E2%80%94surgical-devices/OOK/K181740) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
