Dear You-Jhe Lin:

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. 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); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

The device is equipped with a keypad composed of push buttons which are located below the LCD that control the program selection, strength, channel, and power.

The TENS and EMS Stimulator (Model No .: AK3-20, AK3-25 and AK3-50) is the comination unit with the TENS and EMS functions; the function can be selected by press buttons. The range of settings is identical in models AK3-20 and AK3-25 while model AK3-50 provides 10 types of output modes.

#### 5.7 Non-clinical Testing

A series of safety and performance tests were conducted on the subject device, TENS and EMS Stimulator, TENS Stimulator.

- . Shelf life test
- . Software validation
- EMC and Electrical Safety test ●
- Performance test

All the test results demonstrate that TENS and EMS Stimulator, TENS Stimulator meets the requirements of its pre-defined acceptance criteria, and is substantially equivalent to the predicate device.

{6}------------------------------------------------

#### 5.8 Clinical Testing

No clinical test data was used to support the decision of substantial equivalence.

### 5.9 Substantial Equivalence Determination

The TENS and EMS Stimulator, TENS Stimulator has the same intended use, and technological characteristics with the predicate device (K113010). A series of tests were performed and demonstrated substantial equivalence between the subject and the predicate device. Differences between the devices cited in this section do not raise any new issues of substantial equivalence.
