Abstract
Devices and methods for contactless skin treatment use feedback power control for non-invasive treatment of skin and human tissue. Electromagnetic energy heats skin or tissue. A feedback system measures an output physical quantity before the output of electromagnetic waves from the device into the patient. Alternatively the feedback system scans values of a physical quantity on or near the patient. The devices and methods allow for delivering the optimum amount of energy to the patient while reducing the thermal load of the device.

1-20. (canceled)
A device for contactless skin treatment by electromagnetic waves, comprising:
- a power supply electrically connected to a high frequency generator, and at least two electrodes, each connected to a transmission cable;
- with the high frequency generator generating a high frequency signal which is transmitted by the transmission cables to the at least two electrodes,
- wherein the transmission cables carry a symmetric signal;
- and
- the transmission cables have an outer cylindrical conductor and an internal conductor and a space between the conductors is filled with dielectric material.
