Apparatus and methods for treating biological tissue 200 with RF power delivered from an applicator 240, at least a portion of which mechanically vibrates, are disclosed. In some embodiments, the presently disclosed apparatus includes a vibration generation device 190 operative to cause the at least a portion of the applicator 240 to mechanically vibrate. Typically, the mechanical vibrations have a frequency of between 1 Hz and 100 Hz, and an amplitude of between 0.1-10 mm. In some embodiments, the vibrations primarily include vibrations in a direction substantially perpendicular to a surface of the biological tissue 200 in contact with the applicator 240 through which RF power is delivered. In some embodiments, the vibration parameters (i.e. amplitude or frequency) are determined in accordance with one or more physical parameters associated with the delivering of the RF power to the biological tissue.
