Primary purpose: TREATMENT

Brief summary: This study evaluates the effectiveness and safety of externally applied lower frequency ultrasound to the waist/abdominal region of adults to achieve a reduction of fat cells/tissues below the skin, evidenced by a reduction in patient waist circumference.

Detailed description: This study is to evaluate principally the effectiveness, and secondarily the safety, of external application of lower frequency ultrasound to the waist/abdominal region of adults to achieve a reduction of adipose cells/tissues in the subcutaneous region. The application of higher frequency (200kHz to 3MHz) ultrasound for this purpose has previously been demonstrated and such devices have received clearance for treatment in the United States. The question remains whether application of ultrasound at a lower frequency (35kHz to 45kHz) can achieve comparable results without introducing any new or elevated risks to the patient. This study will apply 3 treatments of the ultrasound energy and evaluate the change in patient's waist circumference, which would be evidence of reducing sub-cutaneous adipose cells/tissues.

* Diabetes or blood-glucose sensitivity
* Any prior invasive cosmetic surgery to the waist or abdominal area, such as liposuction.
* Hernias or diastasis recti within the treatment area.
* Concurrent, or within the last 6 months, participation in any clinical trial for another device or drug.
* Existing bacterial or viral infections (influenza, rhinovirus, hepatitis, pneumonia, tuberculosis, and the like)
* Presence of acne vulgaris, herpes zoster, psoriasis vulgaris, or similar skin conditions in the treatment area.
* Any type of cosmetic treatment to the target area within the last 6 months.
* Implanted active medical device anywhere in the subject, or metallic or polymeric implants in the vicinity of the treatment area.
* Currently undergoing, or recently underwent, chemotherapy or radiation treatment.
* Per the investigator's discretion, any physical or mental condition which may compromise the patient's safety or welfare.
* Failure to complete the study as outlined.

Primary outcomes:
measure: Waist Circumference Change
timeFrame: The difference between the circumference measurement immediately prior to the first treatment (Baseline) to immediately after the 4-week follow-up assessment (approximately 6 weeks from Baseline).
Secondary outcomes:
measure: Number of Participants With Pain
timeFrame: Assessed during and immediately after (up to 15 minutes after use ceased) each application of the device, and at 1 week, 4 weeks, and 12 weeks post-treatment.
