The summary does not mention AI, ML, or related terms, and the device description and performance studies focus on standard RF technology and safety testing.
Yes
The 'Intended Use / Indications for Use' section states the device is used for "relief of minor muscle aches and pain, muscle spasm, and temporary improvement of local blood circulation," which are therapeutic applications.
No
The device is intended for therapeutic purposes (electrocoagulation, hemostasis, relief of minor muscle aches and pain, muscle spasm, and temporary improvement of local blood circulation), not for diagnosis.
No
The device description explicitly lists hardware components such as a host, trolley, footswitch, power cord, and handpieces, indicating it is not software-only.
Based on the provided information, the Unicorn+ RF System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states the device is for "dermatologic and general surgical procedures for electrocoagulation and hemostasis" and for "relief of minor muscle aches and pain, muscle spasm, and temporary improvement of local blood circulation." These are all therapeutic and surgical applications performed on the patient's body.
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, tissue) taken from the human body to provide information for diagnosis, monitoring, or screening. The Unicorn+ RF System does not perform this function.
- Device Description: The description of the components (host, trolley, footswitch, handpieces, electrodes) aligns with a device used for applying energy to the body, not for analyzing biological samples.
- Performance Studies: The performance studies mentioned (biocompatibility, sterilization, shelf-life, electrical safety, software validation, ex vivo tissue testing, skin temperature testing) are all relevant to a device used for therapeutic or surgical procedures on living tissue, not for analyzing samples.
Therefore, the Unicorn+ RF System is a therapeutic/surgical device, not an In Vitro Diagnostic device.

Dear Hongmei Cao:
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. In addition, FDA may publish further announcements concerning your device in the Federal Register.

4. Device Description
Unicorn+ RF System is consist of a host, a trolley, a footswitch, a power cord, three kinds of handpieces and matched electrodes.
Indications for Use 5.
The Unicorn+ RF System is intended for use in dermatologic and general surgical procedures for electrocoagulation and hemostasis. The RF System is used for the relief of minor muscle aches and pain, muscle spasm, and temporary improvement of local blood circulation.
Technological Characteristics in Comparison to the Predicate Device 6.
Although this subject device has three Predicate devices, they have same fundamental technology theory. Operators control host through touch screen, outputs different amounts of RF energy to handpieces and matched electrodes. These three kinds of electrodes(including invasive or non-invasive electrodes) act on different skin depth to achieve different treatment modes.
The subject device has the same intended use and indications for use and the same fundamental scientific technology as the Predicate devices. The subject device design, technology, and the
5
principles of operation are the same as the predicate devices. Although subject device output has minor differences with some predicate devices, and RF Energy= RF Output power × On Time, subject device conducts treatment duration to achieve same treatment with predicates devices. Therefore, the minor differences do not raise any new safety and effectiveness results because the parameters of the Subject device are similar to those of the predicate device.

Unicorn+ RF System belongs Product Code GEI and PBX in Classification,and does not own Needle-type epilator,so that not belong to KCW. Therefore, Unicorn+ RF System Classification code are all same as three predicate devices code. The Unicorn+ RF System is intended for use in dermatologic and general surgical procedures for electrocoagulation and hemostasis. This description is same as POTENZA and AGNES. The RF System is used for the relief of minor muscle aches and pain, muscle spasm, and temporary improvement of local blood circulation. This description is same as Capenergy C Equipment RF System statement, which Capenergy C equipments RF System -C25, C50, C100, C200, C300, C500 are intended to provide topical heating for the purpose of elevating tissue temperature for treatment of selected medical conditions such as: relief of pain, muscle spasms, increase in local circulation, and dermatological procedures. The Unicorn+RF system owns 3 modes matched 3 different types of tips. MicroRF, is Bipolar RF (Radiofrequency) .which is same as POTENZA Bipolar tips in 1Mhz mode, Moreover, Artist&Pure+ tips are Monopolar RF (Radiofrequency) same as others. Treatment depends on device supplied energy , the energy is affected by treatment duration and power supply. Micro RF tips treatment duration is minimal different from POTENZA ones. Artist tips treatment is 50ms-5000ms, much longer than AGNES treatment duration, however, Artist tips max output power is designed 20W, and AGNES is 46W, thus the influence on energy with tissue is also minimal. Finally on Pure+ tips is not a point of use, this tip is effect on skin area, thus the treatment duration depends on treatment area size. MicroRF tips length is no more than POTENZA tips maximum length; Some of Artist tips lengths are longer than AGNES, but tips lengths is effect on treatment target tissue area under the skin, because all tips divided into non-insulated and insulated part, only non-insulated release energy to target tissue.
Conclusion, Unicorn+RF system is designed similar with predicate devices, they are same indications for use, and the operating principle and technological characteristics. Although there are some differences as output power, treatment duration and tip physical dimensions. the thermal damage tests which is compare with the predicate devices and performance test reports are supported to the safety and effectiveness of the subject device.
