Intended Use

The Ulthera System is intended to apply focused ultrasound energy to the body to achieve temporary changes in the physical appearance of the skin. 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. • improve the appearance of skin laxity on the abdomen, anterior arms, and posterior arms. 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

Device Story

Ulthera System uses micro-focused ultrasound to induce thermal coagulation points in dermal/subdermal tissue; results in skin contraction/tightening. System comprises control console, handpiece, and interchangeable DeepSEE transducers. Operator (trained medical professional) uses integrated touchscreen to visualize tissue up to 8mm deep; ensures proper transducer coupling and avoids bone. New version 2.1 adds wireless connectivity via USB Wi-Fi adapter and SEE.PLAN.TREAT. treatment planning mode. Device used in clinical settings. Output is visual feedback for clinician to guide energy delivery; clinical benefit is non-invasive aesthetic improvement of skin laxity and wrinkles.

Clinical Evidence

Bench testing only. Evidence includes electrical safety (IEC 60601-1/1-2), software verification and validation, usability testing per IEC 62366-1 focusing on the SEE.PLAN.TREAT. mode, and cybersecurity assessment. No clinical data provided.

Technological Characteristics

Focused ultrasound stimulator; console with 18.5" touchscreen, handpiece, and interchangeable transducers. Connectivity via USB Wi-Fi adapter. Power: 100-240 VAC. Software version 2.1.6400 running on Windows 10. Imaging mode provides monochromatic, blue-scale (bone), or multicolor (twilight) visualization. Compliant with IEC 60601-1 and 60601-1-2.

Indications for Use

Indicated for adult patients as a non-invasive dermatological aesthetic treatment to lift eyebrows, lift lax submental and neck tissue, improve décolleté lines/wrinkles, and improve skin laxity on the abdomen and arms.

Dear Christopher Lefancheck:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.

# 4 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.

# 5 INTENDED USE / INDICATIONS FOR USE

The Ulthera System is intended to apply focused ultrasound energy to the body to achieve temporary changes in the physical appearance of the skin.

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
- Improve the appearance of skin laxity on the abdomen, anterior arms, and posterior arms

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

# 6 SUMMARY OF TECHNOLOGICAL CHARACTERISTICS

The purpose of this 510(k) notification relates to changes to the software of the Ulthera System to allow for wireless connectivity and implement the new treatment planning mode SEE.PLAN.TREAT.®. Low-intensity, highly focused ultrasound is the main technological principle of both the subject and the predicate device. In both devices, focused ultrasound energy is delivered below the skin and produces discrete points of thermal coagulation that results in contraction of the skin, which produces a lifting or tightening effect and improves appearance of lax tissue, lines, and wrinkles. Both the subject and predicate device share the following similar technological elements:

- Identical ultrasound signal energy.
- Same main components, including a console with integrated touchscreen, connected handpiece, and interchangeable transducers.
- An imaging mode of operation to visualize the treatment area and aid in assuring full/proper skin contact of the transducer to the skin.

The minor software and hardware differences between the subject and predicate systems (see Table 1) do not affect clinical functionality or performance specifications of the system and have been verified and tested.

# 7 PERFORMANCE DATA

The following nonclinical data were provided to support the substantial equivalence of the subject device to the predicate device. In all instances, the subject device functioned as intended.

# 7.1 Electrical Safety

Electrical safety and EMC of the subject device were verified in accordance with IEC 60601-1 and IEC 60601-1-2.

# 7.2 Software Verification and Validation Testing

Software verification and validation testing were conducted, and documentation was provided as recommended by FDA Guidance Content of Premarket Submissions Device Software Functions. A basic documentation level was used, as a failure or flaw of any device software function(s) would not present a hazardous situation with a probable risk of death or serious injury prior to the implementation of risk control measures.

# 7.3 Usability

Usability testing was conducted in accordance with IEC 62366-1 and FDA Guidance, "Applying Human Factors and Usability Engineering to Medical Devices." Testing was focused upon useability of the new SEE.PLAN.TREAT.® mode of the system. Testing demonstrated that clinicians were able to use the device in a representative environment and use conditions. No new risks were identified during the stimulated use study.

# 7.4 Cybersecurity

Cybersecurity testing was conducted, and documentation was provided as recommended by FDA guidance Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions.

# 8 CONCLUSIONS
