Abstract:
1. A device for treatment of skin tissues, the device comprising: at least one RF electromagnetic energy generating unit; a plurality of non-invasive electrodes electrically connectable to said at least one RF electromagnetic energy generating unit for applying RF electromagnetic energy to the skin; and at least one controller unit operatively connected to said at least one RF electromagnetic energy generating unit for controlling the application of electromagnetic energy by said at least one RF electromagnetic energy generating unit to at least one group of electrodes controllably selected from said plurality of electrodes and for controllably changing the selected group of electrodes during the operation of said device, wherein the depth of penetration of said RF electromagnetic energy into said tissues is controlled by controlling the distance between electrodes in said group of electrodes to which said RF electromagnetic energy is applied, and wherein at least one electrode of said plurality of electrodes is a spring mounted electrode movable within a corresponding opening and associated with a respective switching element, and wherein when said spring mounted electrode is moved within the corresponding opening in a contracting direction against the biasing force of the spring, its associated switching element is closed to energize the electrode, and when said spring mounted electrode is moved within the opening by the biasing force of the contracted spring in an extending direction to more than a certain extent, its associated switching element is opened to terminate the energizing of the electrode.
