US Patent 11464993 Device including RF source of energy and vacuum system

A method of soft tissue treatment of a patient comprises placing an applicator onto a surface of a soft tissue, with the applicator including an RF electrode and a dielectric material having a vacuum cup and a dielectric material under the RF electrode, with the dielectric material under the electrode having an absolute value of difference between polarization factor below center of the RF electrode and below edges of the RF electrode in a range from to 0.10005 mm to 19 800 mm, and heating the soft tissue via the RF electrode, and applying vacuum into a cavity under the applicator with changing pressure value inside the cavity under the applicator compared to pressure in the room during the treatment in range from 0.01 kPa to 100 kPa.
