Indications for Use
The Ulthera® System is indicated for use as a non-invasive dermatological aesthetic treatment to: lift the eyebrow lift lax submental (beneath the chin) and neck tissue; which can also affect the appearance of lax tissue in the submental and neck regions improve lines and wrinkles of the décolleté The Ulthera® System in conjunction with the Ulthera® DeepSEE transducer allows for ultrasonic visualization of depths up to 8 mm below the surface of the skin. The inaging is to visualize the dermal and subdermal layers of tissue to: ensure proper coupling of the transducer to the skin confirm appropriate depth of treatment such as to avoid bone
Device Story
Ulthera System uses High Intensity Focused Ultrasound (HIFU) for non-invasive dermatological aesthetic treatment; directs micro-focused acoustic waves to create controlled thermal coagulation points beneath epidermis; utilizes DeepSEE transducer for real-time ultrasonic visualization of dermal/subdermal layers up to 8 mm; used in clinical/doctor's office settings by trained operators; imaging output allows operators to ensure proper transducer coupling and confirm treatment depth to avoid bone; thermal energy (< 2 J) lifts tissue and reduces lines/wrinkles; benefits patients via non-invasive skin tightening and rejuvenation without requiring surface cooling.
Clinical Evidence
Open-label clinical trial evaluated submental and neck tissue lifting. 70 patients enrolled; 51/70 (72.9%) achieved ≥20 mm² improvement in lift; 84.3% of these identified as improved by masked evaluators. Adverse events were mild, short-lived, and resolved without incident. No serious adverse events or unanticipated adverse device effects reported.
Technological Characteristics
High Intensity Focused Ultrasound (HIFU) system; thermal energy < 2 J; non-sterile; reusable control unit/handpiece; single-use transducers; biocompatible patient-contact materials; software-controlled; compliant with IEC 60601-1-3.1 ed. and relevant EMC standards.
Indications for Use
Indicated for non-invasive dermatological aesthetic treatment to lift eyebrows, lift lax submental and neck tissue, and improve lines/wrinkles of the décolleté. Includes ultrasonic visualization of dermal/subdermal layers up to 8 mm depth for transducer coupling and depth confirmation.

Ulthera® System (K134032)
Applicable Guidance: Class II Special Controls Guidance Document: Focused Ultrasound Stimulator System for Aesthetic Use.
The device also conforms to Guidance for Industry and FDA Staff: Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers and Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.
Device Description: The Ulthera® System consists of the Ulthera® Control Unit (with system software), a handpiece with cable, and interchangeable transducers. The device produces controlled tissue coagulation below the skin surface (epidermis) within the first few millimeters of tissue (dermis) using highly focused, low-energy ultrasound deposition. The Ulthera System directs micro-focused acoustic waves to the treatment area at desired depths without affecting or requiring a secondary action to protect the skin surface. The operator may also use the device's supplemental imaging capability to visualize the treatment area and aid in assuring full/proper skin contact of the Ulthera® System transducer to the skin in the target area.
Indications for Use: The Ulthera® System is indicated for use as a non-invasive dermatological aesthetic treatment to:
- lift the eyebrow
- lift lax submental (beneath the chin) and neck tissue; which can also affect the appearance of lax tissue in the submental and neck regions
- improve lines and wrinkles of the décolleté ●

The Ulthera® System in conjunction with the Ulthera® DeepSEE transducer allows for ultrasonic visualization of depths up to 8 mm below the surface of the skin. The indicated use of the imaging is to visualize the dermal and subdermal layers of tissue to:
- . ensure proper coupling of the transducer to the skin
- confirm appropriate depth of treatment such as to avoid bone ●
Summary of Technological Characteristics: High Intensity Focused Ultrasound (HIFU) is the underlying technological principle for both the subject and predicate devices. The Ulthera System functions by directing ultrasonic energy beneath the outer dermis in localized points at a specified distance and depth between points. The design and performance characteristics of the subject and predicate devices are identical. The only technological differences between the devices are minor and do not raise different questions of safety or effectiveness for the subject device as compared to the predicate.

Performance Data: To support the expanded indication, the Ulthera® System was evaluated in an open-label clinical trial investigating the clinical response following treatment with the Ulthera System to achieve lifting of lax submental (beneath the chin) and neck tissue. Improvement was evaluated through quantitative assessment, qualitative assessment and patient satisfaction questionnaires. There were 51/70 patients that had an improvement of ≥20 mm² in lift, of these patients 84.3% were identified as showing improvement by masked evaluators. The adverse events resulting from treatment with the Ulthera® System during this study were mild, short-lived in duration, and resolved without incident. There were no serious adverse events (SAEs) or unanticipated adverse device effects (UADEs) related to treatment with the Ulthera® System.
Conclusion: The Ulthera® System is as safe and effective as the predicate Ulthera® System cleared by FDA in K134032. The subject device has the same intended use and very similar technological characteristics and principles of operation as its predicate device. The minor differences in indications do not alter the intended therapeutic use of the device, and do not affect its safety and effectiveness when used as labeled. In addition, the minor technological differences between the subject Ulthera® System and its predicate raise no new types of safety or effectiveness questions. Thus, the Ulthera® System with modified indications for use is substantially equivalent to the legally marketed predicate device (K134032).
