Dear Lee Rosebush:

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.

{1}------------------------------------------------

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.

#### IV. Description of Device:

The Showa® Medical Exam Glove (Green) Powder-free, Disposable Nitrile Glove is a disposable device intended for medical purposes that is worn on the examiner's hand or fingers to prevent

{4}------------------------------------------------

contamination between patient and examiner. The gloves are single use only, supplied in a nonsterile state, and come in six (6) sizes: XS, S, M, L, XL, and XXL.

The gloves are made of Nitrile Butadiene Rubber, designed, and manufactured in accordance with ASTM D6319-10, Standard Specification for Nitrile Examination Gloves for Medical Application.

Their physical and performance characteristics meet all requirements of ASTM D6319-10. The gloves are powder-free and meet the requirements of ASTM D6124-06. No powder is used during any stage of manufacturing. Rather, the gloves are manufactured using online chlorination - a process wherein the examination gloves are dipped in a dilute chlorine solution to reduce surface friction. More specifically, through the chlorination reaction, the compound is stabilized and further cross-linked and the gloves' surface becomes hardened and smooth, thereby providing the gloves with good donning properties. The gloves then are removed from the chlorination solution and neutralized in an aqueous ammonia solution and washed until any residual chlorine is removed, resulting in the gloves' surface pH being similar to that of water. Once the wash process is completed, the reactive material is removed, thus ceasing the chlorination process.

### Summary of Difference and Comparison of Technological Characteristics- The subject device differs from the predicate in that:

- . The subject device has biodegradation property within landfills tested per ASTM D5526 while the predicate device does not have same technological feature. The difference in biodegradation properties does not affect the subject device's safety and effectiveness; subject device met the requirements for Biocompatibility Testing and ASTM D6319-10 Standard Specification for Nitrile Examination Gloves for Medical Application. The difference in technological feature does not change the performance or affect the intended use of the device.
- Biodegradability is not a medical claim and therefore was not reviewed by FDA. ●
