Abstract

These and other objects of the present invention are achieved in a method for creating a desired tissue effect. An RF electrode is provided that includes a conductive portion. The RF electrode is coupled to a fluid delivery member that delivers a cooling fluidic medium to a back surface of the RF electrode. A dielectric is positioned on a skin surface. The RF electrode is coupled with the dielectric. RF energy is delivered from the RF electrode and the dielectric to the skin surface.

Claims

1. A kit, comprising:

a handpiece;

an RF electrode device including a support structure, first and second engagement members, an RF electrode coupled to the support structure, a first sensor coupled to the RF electrode, and a non-volatile memory coupled to the support structure, the first and second engagement members configured to provide engagement and disengagement with the handpiece;

a fluid delivery member configured to provide an atomizing delivery of a cooling fluidic medium to the RF electrode; and

a dielectric member,

wherein the RF electrode and the dielectric member are configured to capacitively couple RF energy to tissue through the dielectric member to a location beneath a skin surface when at least a portion of the dielectric member is in contact with the skin surface, and the RF electrode is configured to be cooled.

2. The kit of claim 1, wherein the fluid delivery member is configured to deliver a controllable amount of cooling fluidic medium to the RF electrode.

3. The kit of claim 1, wherein the RF electrode includes a back surface and a skin interface surface, and the fluid delivery member is configured to deliver the cooling fluidic medium to the back surface of the RF electrode to evaporatively cool the RF electrode and conductively cool a skin surface in contact with the skin interface surface of the RF electrode.

4. The kit of claim 1, further comprising:

a back plate positioned at a proximal portion of the support structure.

5. The kit of claim 4, further comprising:

a plurality of electrical contact pads coupled to the back plate.

6. The kit of claim 5, wherein each of the first and second engagement members is snap member.

7. The kit of claim 5, wherein each of the first and second engagement members includes an aperture configured to receive a snap member of the handpiece support structure.
