The device is a disposable examination glove and the description and performance studies focus on material properties and physical characteristics, with no mention of AI or ML.
No
Explanation: A therapeutic device is designed to treat or alleviate a medical condition. This device, examination gloves, is for preventing contamination, not for treating any condition.
No
The device description clearly states it is a "disposable device intended for medical purposes that is worn on the examiner's hands to prevent contamination between patient and examiner." This indicates its function is protective and preventative, not diagnostic. There is no mention of it being used to identify or analyze diseases, conditions, or injuries.
No
The device is a physical product (gloves) and the summary describes material properties and physical performance tests, not software functionality.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is clearly stated as "worn on the examiner's hands to prevent contamination between patient and examiner." This is a barrier function, not a diagnostic test performed on samples taken from the body.
- Device Description: The description focuses on the physical characteristics of the glove (material, color, size, powder-free) and its purpose as a barrier. There is no mention of analyzing samples or providing diagnostic information.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring specific substances (analytes)
- Providing information for the diagnosis, monitoring, or treatment of a disease or condition.
- Performance Studies: The performance studies focus on the physical integrity and biocompatibility of the glove, which are relevant for a barrier device, not an IVD.
In summary, the device is a medical glove intended for protection and contamination prevention, not for performing diagnostic tests.

Dear Ray Wang:
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. 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 located 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.
