"Myolift QT" is indicated for facial and neck stimulation and is indicated for over-the-counter cosmetic use.

Device Description

The MyoliftQT is a microcurrent, handheld, and mobile application-based device which is easy to operate. The mobile application used in the device supports both types of users (iPhone®/Android™). The user has to download the application via Google Play™ store (Android) /App Store® (IOs) and connect the device via Bluetooth of their phone. The users can thereafter make their profiles accordingly.

The purpose of this device is to lift and tone the face and neck. It is a battery-powered device used with conductive gel. The conductive gel is used to reduce the impedance between the electrodes and the skin of the user.

Myolift QT has one channel and two output ports. One output is through the applicator ball and the other output is through the lead wire via the USB port connected through the charging port.

The Lead wire is connected to the device via USB. And electrodes are connected through the lead wire to give skin treatment to the user. The Metal balls and the electrodes are in contact with the user/patient maximum of 60 min, therefore the Surface-contacting, less than 24hour duration.

The Sphere shape applicator balls made up of stainless steel in this device are designed to gently roll over the skin to deliver low-level electrical impulses in the face and neck region. The device delivers current in the range of 350 microamperes and low 160-microampere current.

Note: During treatment, only one output port works.

In skin treatment, the device minimize the fine lines and wrinkles on the skin.

This device delivers two types of waveforms (Erase and Educate) for effective skincare treatment.

It is intended to be used by multiple users (multiple applications). The device can be switched ON|OFF by simple touch on the power button.

The device offers multiple LED indications (Visual) to indicate the different states of the device.

  • -A flashing blue LED light indicates that the device is ON|OFF and when the device is connected to Bluetooth, the flashing blue light becomes steady.
  • -A Red LED indicates battery low while A Green LED indicates the chagrining of the device

lt is a portable device having dimensions 6.65″ x 1.49″ [ L X B X H ]. Its outer case is made up of thermoplastic resin. The device comes with a C-type USB cable for the charging of the device. The device is automatically turned off if it is not connected via Bluetooth or not operated for more than 10 minutes.

AI/ML Overview

This document is a 510(k) Summary for the Myolift QT device, which is a Transcutaneous Electrical Nerve Stimulator for cosmetic use. The summary focuses on demonstrating substantial equivalence to a predicate device (ZIIP+ Device, K212342) rather than presenting a performance study with acceptance criteria in the typical sense for an AI/ML medical device.

Therefore, many of the requested elements for an AI/ML study (e.g., sample size for test set, number of experts for ground truth, MRMC study, standalone performance) are not applicable or not provided in this document. The "acceptance criteria" here are based on meeting various electrical safety, biocompatibility, and quality standards, and demonstrating technological characteristics similar to the predicate device.

Here's a breakdown of the available information based on your request:

1. Table of Acceptance Criteria and Reported Device Performance

In comparison to the predicate device, there is no change or difference in the indications for use, fundamental scientific principles, performance specifications, or operation of the device. The minor differences in the construction of the devices do not raise any questions regarding the safety and effectiveness of the new device (MYOLIFT QT). The electrical values are within the limits as per the "Guidance Document for Powered Muscle Stimulator 510(k)s", issued on June 9, 1999, ANSI/AAMI NS4:2013 (R2017) standard for electrical stimulators.

The fundamental scientific technology is not changed in the new device, and the changes are solely considered for ease of use to the clinician. The Myolift QT generates the same stimulation for the face and neck for cosmetic purposes.

While designing the Myolift QT, complete care and considerable measures have been taken to retain its safety and effectiveness.

{11}------------------------------------------------

Non-clinical Testing

The following bench testing was conducted for design and performance elements deemed appropriate to demonstrate equivalence to the predicate device. The Myolift QT device met the predetermined acceptance criteria ensuring substantial equivalence to the previously cleared device. No new safety or performance issues were raised during testing.

Non-clinical Bench Testing:

  • Reliability Testing
  • Compliance Testing (IEC60601-1, IEC60601-1-2, IEC60601-1-11) ●
  • Quality management systems - Requirements for regulatory purposes (ISO 13485:2016)
  • Quality System Regulation (21CFR820)
  • Application of usability engineering to medical devices (IEC 62366)
  • Application of risk management to medical devices (ISO 14971)
  • Symbols to be used with medical device labels, labelling and information to be supplied (ISO 15233)
  • Biological evaluation of medical devices (ISO 10993-1)
  • 47 CFR Part 15 FCC requirements of the Equipment Authorization - RF Device

CONCLUSION
