Summary of Performance Studies
The following nonclinical performance testing has been conducted to support the substantial equivalence of the SofWave System to its predicate device, consistent with FDA's "Class II Special Controls Guidance Document: Focused Ultrasound Stimulator System for Aesthetic Use" (2011). 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
- Software verification and validation was performed, and demonstrated that the software performs as intended
- Electrical Safety and Electromagnetic Compatibility was established in accordance with IEC 60601-1-2: 2014, IEC 60601-1: 2005 (R) 2012 , IEC 60601-1-6: 2010 (R) 2013, and IEC 60601-2-62: 2013
- Ultrasound energy safety was established in accordance with IEC 60601-2-62: 2013
- Functional bench testing was conducted to verify the device performance (acoustic mapping and parameter measurement testing, applicator performance testing, handle acoustic emission measurements, transducers linearity experiment, power control and output, cooling power, etc.)
- In vivo testing in an animal model was performed to evaluate and establish the safety and effectiveness of the subject device
To support the expansion of indications, the Company conducted a clinical study that evaluated the safety and effectiveness of the device for the non-invasive dermatological aesthetic treatment to lift the eyebrow and lift lax submental and neck tissue. A total of 92 subjects were enrolled and 80 subjects were treated at 5 investigational sites in the United States. Each subject was treated on 3 face and neck zones including the forehead and temples for eyebrow lifting (Zone 1), the cheeks (Zone 2), and the submental and the neck (Zone 3). Overall, 467 facial areas were treated during the study course.
For Zone 1, the co-primary effectiveness endpoints were the independent masked evaluators' correction identification of pre-post image sequence for eyebrow lift, and the objective measurement of maximal eyebrow lift according to quantitative 2D imaging. The results demonstrate that the blinded reviewers identified correctly the pre- and post-treatment photographs for 79% (53/67) of the treated subjects (based on the agreement of two blinded reviewers). Objective measurement of eyebrow lift by quantitative 2D imaging demonstrated an average lift of 0.78 mm for maximal eyebrow height (MEH) and 0.69 mm for average eyebrow height (AEH). Therefore, both co-primary endpoints are met. With regard to the secondary endpoints, progressive improvement was noticed along the study course and 80% (51/64) of subjects were improved based on Physician Global Aesthetic Improvement Scale (PGAIS) assessment at the 3-month follow-up visit.
For Zone 3, the co-primary effectiveness endpoints were the independent masked evaluators' correction identification of pre-post image sequence for submental lift, and the objective measurement of lax submental and neck tissue lift according to quantitative 2D imaging. The results demonstrate that the blinded reviewers identified correctly the pre- and post-treatment photographs for 80% (60/75) of the treated subjects (based on the agreement of two blinded reviewers). Objective measurement of lax submental and neck tissue lift by quantitative 2D imaging demonstrated an average lift of 38 mm². Therefore, both co-primary endpoints are met. With regard to the secondary endpoints, progressive improvement was noticed along the study course and 85% (61/72) of subjects were improved based on Physician Global Aesthetic Improvement Scale (PGAIS) assessment at the 3-month follow-up visit.
The patient satisfaction questionnaire demonstrated that 55% of subjects reported improvement and satisfaction for the eyebrow lift. For the question, would you undergo further treatments, 37/64 (58%) said yes. 14/64 (17%) replied no and 13/64 (20%) replied not sure. 55% of subjects reported improvement for submental and neck lift. 50% of subjects reported satisfaction. For the question, would you undergo further treatments, 43/72 (60%) of subjects said yes. 14/72 (19%) subjects said no and 15/72 (21%) subjects said not sure.
The clinical study also demonstrated a favorable safety profile for the SofWave for the proposed use in eyebrow lift and lax submental and neck tissue lift. Throughout the study, only one device related adverse events were reported, which was moderate, transient, and resolved completely with topical cream only. No serious or unanticipated adverse event was reported during the study. The mean pain level during treatment was 6.4 out of 10 for Zone 1 and 5.3 out of 10 for Zone 3. Based on a literature review, the study results were consistent with the predicate device.

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.
Comparison of Technological Characteristics with the Predicate Device
The SofWave System has similar technological characteristics compared to its predicate device, the Ulthera System (K180623). Both the subject device and the predicate device consist of a console that includes the power sources, electrical components, user interface (touchscreen), a cart for storage of system components, and a handpiece that is connected to a transducer.
The technological characteristics of the console of the subject device and the predicate device are similar. The console of both the subject and predicate device are assembled in a mobile cart that comprises of a control unit (or personal computer (PC)) with a touchscreen monitor and Graphical User Interface (GUI). The control unit of both the subject and predicate device allow the operator to adjust the treatment settings, view the system status and receive maintenance notices, fault and safety alerts. Further, the main processor of both the subject and predicate device control and monitor all system components. The computers for both systems receive input from the user via the user interface where treatment parameters can be adjusted accordingly. During the treatment, relevant information is displayed on the screen for both the subject and predicate device such as the operating conditions, equipment activation status, treatment parameters, system messages and prompts, and ultrasound images. Further, both the subject and predicate device consist of a main board that includes all electronic circuits required for operating the system.
Both the subject device and predicate device consist of software that enables the continuous monitoring of the overall applicator and console to ensure safe usage. The software for both devices monitors various parameters including operating conditions, equipment activation status, treatment parameters, system messages and prompts.
The technological characteristics of the applicator of both the SoftWave System and the predicate device are also similar. The applicator of both the subject and predicate device are comprised of ultrasonic transducers that emit continuous acoustic waves and is connected by a flexible cable (umbilical cord) connecting the handle to the control unit (console). The thermal coagulation point of both the subject device and predicate device are similar (confined to a focal zone which is
