The description focuses on the physical properties and function of a heat lamp, with no mention of AI or ML capabilities.
Yes
The device is used for the "temporary relief of minor muscle and joint pain and stiffness," and "relaxation of muscles." These uses are therapeutic in nature, aiming to alleviate symptoms and promote well-being.
No.
The device description and intended use indicate that the WS-501 Heat Lamp is used for therapeutic purposes (pain relief, circulation increase, muscle relaxation) by providing topical heating, not for diagnosing medical conditions.
No
The device description explicitly details hardware components such as a ceramic plate, power requirements (110 volt, 20 watts), a hi and low switch, and a table top stand, indicating it is a physical device, not software only.
Based on the provided information, the WS-501 Heat Lamp is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device that applies heat topically to the body for therapeutic purposes (pain relief, circulation, muscle relaxation). This is a physical therapy or medical device function, not an in vitro diagnostic function.
- Device Description: The description details a heat lamp with a ceramic plate and specific power and emission characteristics. This aligns with a device that delivers energy to the body, not a device that analyzes samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any process that would involve testing something in vitro (in glass or outside the living organism).
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. The WS-501 Heat Lamp does not perform any of these functions in an in vitro manner.
N/A
Intended Use / Indications for Use
The WS-501 Heat Lamp may be used for the temporary relief of minor muscle and joint pain and stiffness, the temporary relief of minor joint pain associated with arthritis, the temporary increase in local circulation where applied, and the relaxation of muscles. In addition, the WS-501 Heat Lamp may also help muscle spasms, minor sprains and strains, and minor muscular back pain.

Dear Mrs. Riihimaki:
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. Iisting 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 reguirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
