The summary describes a radiofrequency device for wrinkle treatment and does not mention any AI or ML components or functionalities. The performance studies focus on electrical safety, power output, and software validation, not on algorithmic performance related to AI/ML.
Yes
The device is intended for the non-invasive treatment of facial wrinkles, which is a therapeutic purpose.
No
The device is described as being for "non-invasive treatment of mild to moderate facial wrinkles," indicating a therapeutic rather than diagnostic purpose.
No
The device description explicitly states that the device consists of hardware components: the applicator unit and the power supply. It also mentions delivering RF current, which is a physical process requiring hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "non-invasive treatment of mild to moderate facial wrinkles." This describes a therapeutic or cosmetic treatment applied directly to the body, not a test performed on a sample taken from the body.
- Device Description: The device delivers RF current into the skin to generate heat. This is a physical interaction with the body, not a process of analyzing biological samples.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing diagnostic information about a disease or condition
IVDs are used to examine specimens from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.
