The summary describes a standard TENS device with pre-set modes and does not mention any AI/ML capabilities or data processing beyond basic electrical stimulation.
No.
The device is indicated for "over-the-counter aesthetic use," which is not considered therapeutic.
No
The device is indicated for over-the-counter aesthetic use, including facial, neck, or body skin stimulation. It uses transcutaneous electrical stimulation (TENS) for aesthetic purposes and is described as a skin toning device, which is not a diagnostic function.
No
The device description explicitly states it is a "handheld, AA battery-operated portable device" with "built-in electrodes," indicating it is a hardware device that utilizes electrical stimulation.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "over-the-counter aesthetic use including facial and neck stimulation or body skin stimulation." This describes a physical intervention on the body for aesthetic purposes, not a test performed on samples taken from the body to diagnose or monitor a condition.
- Device Description: The device is a "handheld, AA battery-operated portable device" that uses "transcutaneous electrical stimulation (TENS)." This is a physical therapy or aesthetic device, not a device designed to analyze biological samples.
- Lack of IVD Characteristics: The description 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 or markers
- Providing information for diagnosis, monitoring, or prognosis of a disease or condition
The device's function is to apply electrical stimulation to the skin for aesthetic purposes, which falls outside the definition of an In Vitro Diagnostic device.

Dear Ms. Lahutsky:
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.

Comparison of technical characteristics with the predicate devices
Transcutaneous electric nerve stimulation (TENS) is the technological principle for both the subject and predicate devices. It is based on the use of electric stimulation to the skin for aesthetic use.
At a high level, the subject and predicate devices are based on the following same technological elements:
- . Transcutaneous electric nerve stimulation (TENS) to the skin for aesthetic use
- . Quantity of electric stimulation applied to the skin resulting from short, pulsed electrical current that results in only microamperage applications per second, also known as microcurrent.
- . Meet the same medical device general safety requirements IEC 60601-1 and requirements EMC: IEC 60601-1-2.
There are variations between the subject and predicate devices for specific waveform shape, max voltage, phase charge, pulses per second, duty cycle and current.
Rationale that differences in technical performance specifications are within range of equivalence, and therefore, do not raise new questions.
The variations in technical characteristics fall within the range of Agency accepted differences for devices with the same principal of operation and the same intended use. This is consistent with the Agency accepted standard, ANSI/AAMI NS4:2013/ (R)2017 Transcutaneous electrical nerve stimulators, that references combination of current or charge over time for determining safety for Transcutaneous electrical stimulators.
The ANSI/AAMI document established a maximum charge to prevent serious injury or death.
8
page 6
Peak instantaneous maximum voltage and pulse width are considered and included in determination of charge per pulse and the resulting current flow and determining safety.
The candidate devices fall within the same range of equivalence for performance and energy output for meeting the ANSI/AAMI NS4:2013/(R)2017 standard requirements for safety; and therefore, they do not raise new questions of safety.
Nonclinical Tests
Nonclinical bench testing was performed to demonstrate that the candidate device met design specifications and accepted safety standards and requirements.
Performance testing was conducted using a production equivalent of the candidate device. The testing consisted of the evaluation of output waveform and energy characteristics. Results were compared to predicate device performance characteristics.
Additionally, output energy, electrical and constructional safety and EMC testing of the candidate device was conducted in accordance with Medical electrical equipment – Part 1: General requirements for basic safety and essential performance, IEC 60601-1:2005 MOD, Medical electrical equipment - Part 1-2 : General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic disturbances - Requirements and tests, IEC 60601-1-2, Edition 4.0 2014-02, and Medical electrical equipment - Part 2-10: Particular requirements for the basic safety and essential performance of nerve and muscle stimulators, IEC 60601-2-10, 2016.
The software development process and software verification is conducted according to Medical device software – Software life cycle processes, IEC 62304, 2015 and the Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices – Guidance for Industry and FDA Staff – May 11, 2005.
Usability study was performed to assess the candidate device for aesthetic use. The candidate device and accompanying instructions for use met requirements for usability factors for over-the-counter use. No new questions of safety or efficacy were raised. No new risks were raised. The instructions for use support the safe and effective use of the EZZI-LIFT device and accessories for aesthetic use. Reference FDA guidance, "Applying Human Factors and Usability Engineering to Medical Devices, Guidance for Industry and Food and Drug Administration Staff", 2016 and IEC 62366, Medical devices - Part 1: Application of usability engineering to medical devices, 2015.
Results from bench testing and performance tests are compared to that of predicate devices in a comparison table format.
Nonclinical test results and studies, including the performance bench testing, product safety testing, software, usability studies, and risk management activities in conformance with Medical devices — Application of risk management to medical devices, ISO 14971, 2012 were reviewed and evaluated.
The candidate devices fall within the same range of equivalence for output energy characteristics and construction for meeting accepted safety standards for transcutaneous electrical nerve and muscle stimulators; and therefore, they do not raise new questions of safety.
Results confirmed that design and safety requirements were met, and that no new questions of safety or effectiveness were raised. This data was used to determine substantial equivalence.

Safety and Effectiveness
The Avazzia device technological specifications are similar; therefore, they do not pose new questions regarding safety and effectiveness.
Indications for use for TENS OTC for aesthetic use have been established, therefore, indications for use do not pose new questions regarding safety and effectiveness.
Conclusion
The Avazzia EZZI-LIFT device has intended use and technological characteristics that are substantially equivalent to the predicate devices.
