The device is intended for multiple use and therefore, it must be cleaned according to the instructions provided in the Instruction For Use. The InMode WMface hand piece comes in contact with the skin surface. All device materials in contact with the skin surface are biocompatible.

Non-Clinical (Bench) Performance Data:

Several performance tests were conducted to evaluate the effectiveness and safety of the InMode WMface device and its equivalence to the predicate device. A bench test was performed to measure the accuracy of the RF output parameters in the InMode WMface device and compare them to the RF output measurements in the predicate device (EndyMed Imagine TC Skin Treatment System). The results of the bench test demonstrated that the InMode WMface device has the same RF output specifications as the predicate device and therefore, is substantially equivalent to the predicate device.

An additional bench test was performed to demonstrate that the InMode WMface device and the predicate device consistently maintain the skin temperature below the specified temperature limit during the recommended treatment period and using different RF output power settings. The results demonstrated that both devices tested at the same RF energy outputs maintain the skin temperature below the specified temperature limit.

An additional ex-vivo test was performed to evaluate and compare the thermal energy distribution generated by the WMface device and the EndyMed Imagine System. The testing performed on a porcine tissue model using different RF output power settings and time intervals demonstrated an identical energy distribution pattern, penetration depth and maximal temperature in both devices.

Clinical Performance Data:

Not Applicable

Substantial Equivalence:

The indications for use and technological characteristics of the InMode WMface device are substantially equivalent to the indications for use and technological characteristics of the EndyMed Imagine TC Skin Treatment System.

The design and components in the InMode WMface device, including the console (with power supply, RF generator, controller and display panel) and the hand piece applicator (with cable and connector to console) are similar to the design and components found in the predicate EndyMed Imagine TC Skin Treatment System. The minor differences are insignificant and do not influence the safety or efficacy of the device as shown in the performance tests provided in section 18. The performance specifications (including frequency, RF output power and pulse duration) of the InMode WMface device are

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

substantially equivalent to those in the EndyMed Imagine TC Skin Treatment System. Both devices demonstrated similar temperature and thermal profiles behaviors as was shown in the performance tests. The safety features and compliance with safety standards in the InMode WMface device are similar to the safety features and compliance with safety standards found in the predicate device. Patient contact materials are also similar. Any minor differences in the technological characteristics do not raise new safety or effectiveness concerns. Furthermore, the new InMode WMface device underwent performance testing, including software validation testing (provided in Section 16) and electrical and mechanical safety testing according to IEC 60601-1 and electromagnetic compatibility testing according to IEC 60601-1-2 (provided in Section 17) and bench tests (provided in Section 18). These performance tests demonstrated that the minor differences in the device specifications meet the system requirements and do not raise new safety or effectiveness concerns.

Consequently, it can be concluded that the InMode WMface device is substantially equivalent to the predicate EndyMed Imagine TC Skin Treatment System, cleared under 510(k) K083461, and therefore, may be legally marketed in the USA.

Conclusions:

Based on the performance testing and comparison to predicate devices, the InMode WMface device is substantially equivalent to the EndyMed Imagine TC Skin Treatment predicate device.
