Device Description

The Tyece OTC TENS Device EM26, EM27, EM28 and EM29 powered by 4.5V (3 x 1.5V AAA /Alkaline batteries), is similar to the predicate device, LT3060 (K130802), with the following features:
a. It is a portable single-channel, battery operated Transcutaneous Electrical Nerve Stimulator stimulation system. The predicate is a dual-channel TENS device.
b. It contains 4 programs, similar to the predicate device which has 12 programs
c. The output strength is adjustable from 0-110mA, similar to the predicate device at 0-96mA, via regulated voltage.
d. The LCD display is provided for the indication of operation status including operation mode, output program mode, output intensity, time to cut-off, and battery low indication.

AI/ML Overview

The provided document is a 510(k) Premarket Notification from the FDA regarding the Tyece OTC TENS Devices (Models EM26, EM27, EM28, and EM29). This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than proving clinical effectiveness through novel studies.

Therefore, the document does not contain the information requested regarding acceptance criteria and a study proving a device meets those criteria, as it relates to a typical AI/ML device submission's performance evaluation.

Specifically, it lacks data on:

  1. A table of acceptance criteria and reported device performance: The document compares technical specifications of the Tyece TENS devices to a predicate device, but this is not an "acceptance criteria" table in the context of an AI/ML device's performance (e.g., sensitivity, specificity, AUC).
  2. Sample size and data provenance for a test set: No specific test set for evaluating AI/ML algorithm performance is mentioned.
  3. Number and qualifications of experts for ground truth: Not applicable, as there's no AI/ML algorithm requiring expert ground truth for interpretation.
  4. Adjudication method: Not applicable.
  5. Multi-Reader Multi-Case (MRMC) comparative effectiveness study: Not conducted. The TENS device is a physical product, not an AI.
  6. Standalone (algorithm only) performance: Not applicable.
  7. Type of ground truth: Not applicable.
  8. Sample size for training set: Not applicable.
  9. How ground truth for training set was established: Not applicable.

Instead, the document details the technical comparisons of the Tyece TENS devices to a predicate TENS device (LT3060, K130802) and a reference device (Savia OTC TENS Model EM-38, K113321). The "study" mentioned here refers to non-clinical testing performed to validate design conformance with voluntary standards (e.g., IEC 60601 series for electrical safety and electromagnetic compatibility) and software validation. These tests are intended to demonstrate that the Tyece devices maintain the same safety and effectiveness as the predicate device despite some differences in specifications (e.g., single vs. dual channel, different battery types, output parameters). The "discussion of differences" in the tables explains why these differences do not adversely impact safety and effectiveness, leading to the conclusion of substantial equivalence.

Dear Maria Griffin:

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 (OS) 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). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

Conclusion

The Tyece OTC TENS Device EM26, EM27, EM28 and EM29 has the same intended use and similar technological characteristics as the cleared predicate device. Moreover, verification and validation tests demonstrate that the differences in the submitted models maintain the same safety and effectiveness as that of the cleared device. Therefore, we conclude that the subject device is substantially equivalent to the predicate device.
