No
The summary does not mention AI, ML, or any related concepts like deep learning, neural networks, or image processing. The device description focuses on laser technology and app control for monitoring usage, not intelligent data analysis or decision-making.
Yes
The device is indicated for adjunctive use in the temporary relief of low-back pain and wrist pain, which addresses a medical condition, directly supporting its classification as a therapeutic device.
No
The device description and intended use state that it is for temporary pain relief, not for diagnosing medical conditions.
No
The device description explicitly states it uses "semiconductor lasers to generate three wavelengths of light" and "irradiates to the pain area with a laser beam," indicating it is a hardware device that emits light, not solely software. While it mentions a smartphone app for control and monitoring, the core therapeutic function is performed by the laser hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The Pain TB and Pain TJ Laser systems are described as devices that use laser irradiation to relieve pain in the low-back and wrist. They are applied externally to the body.
- Intended Use: The intended use is for the temporary relief of pain, not for diagnosing a disease or condition based on in vitro analysis of biological samples.
- Device Description: The description focuses on the physical characteristics of the device (semiconductor lasers, wavelengths) and its application method (irradiating the pain area).
- Performance Studies: The performance study described evaluates the device's effectiveness in reducing pain based on patient-reported pain levels (VAS score), not on the analysis of biological samples.
Therefore, the Pain TB and Pain TJ Laser systems fall under the category of therapeutic devices, not in vitro diagnostic devices.

Summary of Performance Studies
The PainTB was evaluated in a prospective, rater blind, randomized study that compared the "Active" Laser with a "Mock" Laser. The single-center study was conducted in the South Korea. In the test, 60 adult patients of back pain whose VAS score is 4 or higher are recruited as subiects. PainTB alone test and exercise treatment combined with PainTB use and "Mock" device use are conducted, and VAS measurement has used as pain level scale.
Statistical analyses (one-way ANOVA) were performed by generally accepted statistical techniques to evaluate the differences between the VAS scores before and after treatment follow up for patients in Group B (Active Laser + exercise treatment) and Group C (Mock Laser + exercise treatment).
The statistical analyses of the data demonstrate that the difference between the two treatment groups over time is statistically significant (p-value

8. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
The mechanism for pain treatment using Non-heating Infrared ramp has been studied for a long time, and various products have cleared FDA 510(K) and are being used as medical devices for treatment. Our product have three wavelength's diode laser(670nm, 839nm, 910nm) and they are cross irradiated so don't be overlay to another wavelength when it is working. Also, each wavelength is generally used in pain treatment, and we can easily find similar product in the market.
The following is the result of comparing our product with the similar product in clinical literatures chosen. At the technical aspect, light sources and wavelength optical power were compared. The similar product used diode Laser and its wavelength was 830nm so it is same wave length as ours. Optical power of similar product is 30mW and our 830nm is 24.1mW so it is within the acceptable range. Thus, this product and our product have technical equivalence. In addition, the application range and the effect of the product were compared at the clinical aspect. The predicate device was used at pain treatment and reduced pain so it is same as ours. Thus, this product and our product have clinical equivalence.
There is some gap in comparison with similar products because our product have 2 more wavelength laser used. Although 830nm is major and other 670nm and 910nm laser is lower power for supporting performance of the treatment, it is showing gap with predicate device.

The PainTB was evaluated in a prospective, rater blind, randomized study that compared the "Active" Laser with a "Mock" Laser. The single-center study was conducted in the South Korea. In the test, 60 adult patients of back pain whose VAS score is 4 or higher are recruited as subiects. PainTB alone test and exercise treatment combined with PainTB use and "Mock" device use are conducted, and VAS measurement has used as pain level scale.
Clinical Data Analysis and Results
Statistical analyses (one-way ANOVA) were performed by generally accepted statistical techniques to evaluate the differences between the VAS scores before and after treatment follow up for patients in Group B (Active Laser + exercise treatment) and Group C (Mock Laser + exercise treatment).
The statistical analyses of the data demonstrate that the difference between the two treatment groups over time is statistically significant (p-value
