Indications for Use
The SofWave System is indicated for use as a non-invasive dermatological aesthetic treatment to improve facial lines and wrinkles, lift the eyebrow, and lift lax submental (beneath the chin) and neck tissue; which can also affect the appearance of lax tissue in the submental and neck regions for subjects aged 22 and older. The SofWave System is also intended for short-term improvement in the appearance of cellulite and the treatment of acne scars. The SofWave System is indicated to improve the appearance of skin laxity on the upper arms.
Device Story
The SofWave System is a non-invasive aesthetic device using high-intensity, non-focused ultrasound to treat skin laxity and wrinkles. The system comprises a console (power, cooling, UI) and an applicator containing an array of ultrasonic transducers. The applicator emits continuous acoustic waves to heat the dermis, causing controlled thermal damage, while an integrated active cooling element protects the skin surface. Used in clinical settings by trained professionals, the device provides visual feedback via an LCD touchscreen. The output is thermal energy delivered to the dermis; this stimulates tissue response to improve skin appearance. The device is used for facial, submental, neck, and upper arm treatments. Clinical benefits include improved skin laxity, reduced wrinkles, and scar treatment with a favorable safety profile.
Clinical Evidence
Prospective, single-arm, multicenter study (n=46) evaluated upper arm skin laxity improvement. Subjects received 2 treatments (1-3 weeks apart) with 3-month follow-up. Primary endpoint: 93% of treated arms showed improvement via blinded photo review. Secondary endpoints: average improvement from severe to moderate laxity on a 5-point scale; 93% of arms rated 'improved' or 'very much improved' on the Global Aesthetic Improvement Scale. No device-related adverse events reported; anticipated responses (erythema, edema) resolved spontaneously.
Technological Characteristics
High-intensity non-focused ultrasound system. Components: console (power, cooling, UI) and applicator (transducer array). Energy: 3-5 J/PZT (6-10 J/cm²). Treatment area: 15 or 35 mm².

Indications for Use
Indicated for non-invasive dermatological aesthetic treatment in subjects aged 22 and older. Uses include: improvement of facial lines and wrinkles, eyebrow lifting, lifting of lax submental and neck tissue, short-term improvement of cellulite appearance, treatment of acne scars, and improvement of skin laxity on the upper arms.

## Predicate Device
SofWave Medical's SofWave System (K231537)
## Technological Characteristics
The SofWave System is an ultrasound system intended for aesthetic purposes. The system generates high frequency ultrasonic pulses that elevate the temperature in the dermis layer and cause controlled isolated areas of thermal damage.
The SofWave System consists of two main functional components: 1) the console, and 2) the applicator. The console includes the power sources, cooling unit, electrical components, loT, and the user interface. The applicator is comprised of an array of ultrasonic transducers that emit continuous acoustic waves and an active cooling element that is used to cool the skin area in contact with the applicator. The applicator is connected by a flexible cable to the console.

#### Performance Data
#### Nonclinical Testing
The following nonclinical testing was conducted to support substantial equivalence of the SofWave System to its predicate device. In all instances, the SofWave System functioned as intended.
- Biocompatibility of the patient-contacting components of the device was established in accordance with ISO 10993-1.
- Software verification and validation was performed and demonstrated that the software performs as intended.
- Electrical safety and electromagnetic compatibility were established in accordance with IEC 60601-1-2, IEC 60601-1, IEC 60601-1-6, and IEC 60601-2-62.
- . Functional bench testing was conducted to verify that the modifications to the device did not affect the device performance.
## Clinical Testing
To support the expansion of the device's indications for use, a single arm, prospective, selfcontrolled, multicenter study was conducted to evaluate the SofWave device for improving the appearance of skin laxity on the upper arms. A total of 46 subjects were enrolled and treated on both upper arms at 4 sites in the United States. Subjects attended 2 treatment sessions (1-3 weeks apart) and a follow-up visit 3 months after the final treatment visit.
The primary efficacy evaluation found that 93% of treated arms showed improvement in upper arm skin laxity, as assessed by the correct identification of the pre- and post-treatment photographs by at least 2 of 3 blinded reviewers. Consistent with the results for the primary efficacy endpoint, the secondary efficacy endpoint results also supported device effectiveness for the expanded indications for use. As assessed by the blinded reviewers, on average the treated arms improved from severe skin laxity at baseline to moderate skin laxity after treatment, based on a 5-point upper arm skin crepiness/laxity grading scale. Additionally, 93% of the treated arms were improved or very much improved in appearance, as rated by the blinded reviewers using the Global Aesthetic Improvement Scale.
{7}------------------------------------------------
The clinical study also demonstrated a favorable safety profile for the SofWave System for use in improving the appearance of skin laxity on the upper arms. Throughout the study, there were no device-related adverse events. Anticipated tissue responses mostly consisted of erythema and edema that resolved spontaneously after treatment. Most subjects reported none to mild levels of pain during treatment and no discomfort afterward, further confirming that the device was welltolerated.
## Conclusion
SofWave has the same general intended use and similar indications, technological characteristics, and principles of operation as the company's previously cleared SofWave System (K231537). The minor technological differences between the subject and the predicate device do not raise different questions of safety or effectiveness. Performance testing of the device has demonstrated that the device performs as intended and thus is substantially equivalent.
