No
The description focuses on microprocessor control for dose selection and targeted light delivery, with no mention of AI or ML capabilities.
Yes
The device is indicated for the treatment of various skin conditions, which directly addresses therapeutic goals.
No
The device is described as a phototherapy system used for the treatment of various skin conditions by delivering UV light. It does not perform any diagnostic functions like analyzing images or patient data to identify or determine the nature of a disease.
No
The device description explicitly states it is a "microprocessorcontrolled, high-intensity ultraviolet light source" with a "flexible Lightguide and Handpiece," indicating it is a hardware device that delivers UV light.
Based on the provided information, the TheraLight UV120-2 UVA / UVB Phototherapy System is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the treatment of skin conditions (psoriasis, vitiligo, atopic dermatitis, seborrheic dermatitis) using UV light. This is a therapeutic application, not a diagnostic one.
- Device Description: The device is described as a light source that delivers UV light to the skin. This aligns with a therapeutic device, not a device used to examine specimens from the human body.
- Lack of IVD Characteristics: There is no mention of the device being used to test samples (blood, urine, tissue, etc.) or to provide diagnostic information about a patient's condition based on such testing.
IVD devices are used to examine specimens from the human body to provide information for the diagnosis, monitoring, or treatment of a disease or condition. The TheraLight UV120-2 is a therapeutic device that directly treats the patient's skin.

Device Description
The TheraLight UV120-2 UVA / UVB Phototherapy System is a microprocessorcontrolled, high-intensity ultraviolet light source. The desired dose of UVA or UVB light is selected using controls on the System front panel. The System provides "targeted" phototherapy, whereby the specified dose of UVA or UVB light is delivered via a flexible Lightguide and Handpiece. The System delivers a homogenous UV light dose to a localized ¼'' square patch of skin without exposure to neighboring, healthy tissues.

Intended Use:
The TheraLight UV120-2 UVA / UVB Phototherapy System is intended for use in PUVA photochemistry and UVB phototherapy for the treatment of psoriasis, vitilizo, atopic dermatitis (eczema), and seborrheic dermatitis.
Substantial Equivalence:
The TheraLight UV120-2 UVA / UVB Phototherapy System emits UVA within a spectral band of 330-380nm, which is the same as that for the predicate HOUVA II UVA device (K885025). The TheraLight System and each of the cited predicate devices emit UVB within a spectral band of 290-330nm, which has been shown to be safe and effective in the treatment of the indicated skin diseases.
The major difference between the TheraLight device and the cited predicate devices is that the TheraLight device will emit either UVA or UVB. The user selects which spectra will be emitted using a switch on the device front panel. However, TheraLight believes that this difference is an added convenience, and does not raise new questions of safety or effectiveness.
Performance Data:
With regard to UVA light emissions, the TheraLight System is the first device to emit light via a small (3/4" square) Handpiece aperture. The predicate device was designed to provide whole body (or limb) exposure. The TheraLight, Inc. design allows for the treatment of lesional skin without exposure to healthy, neighboring tissues.
Performance data were submitted as part of the 510(k) to confirm that the spectral output from the TheraLight System is between 330-380nm for UVA, and between 290-330nm for UVB, which is similar to spectra emitted by predicate devices.
With regard to UVB light emission, the performance specifications for the TheraLight UV120-2 UVA / UVB Phototherapy System are the same as, or very similar to, those claimed by predicate devices.
Conclusion:
On the basis of the information provided in this Summary, TheraLight, Inc. believes the UV120-2 UVA / UVB Phototherapy System is substantially equivalent to legally commercialized predicate devices.

Dear Mrs. Drew:
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 (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. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
