Method and kit for treatment of tissue

Abstract

Methods 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.

1 . A system configured to transcutaneously treat tissue with electromagnetic energy, the system comprising:
 a first treatment electrode;   a generator coupled with the first treatment electrode, the generator configured to generate the electromagnetic energy; and   a system controller coupled with the generator, the system controller configured cause the electromagnetic energy to be provided from the generator to the first treatment electrode with a power profile having a plurality of differing power levels over a treatment time divided into a plurality of time intervals each associated with a respective one of the power levels.   
     
     
         2 . The system of  claim 1  wherein the differing power levels range from a first power that is at least 20 percent above a nominal power of 200 joules per second to a second power that is at least 20 percent below the nominal power of 200 joules per second. 
     
     
         3 . An apparatus comprising:
 a first treatment electrode having a surface;   a tip frame composed of an electrically-insulating material, the top frame including an opening having an inner edge and an outer peripheral edge, the opening arranged relative to the surface of the first treatment electrode to expose a first portion of the first treatment electrode and to cover a second portion of the surface of the first treatment electrode,   wherein the second portion of the surface of the first treatment electrode is located between the outer peripheral edge of the tip frame and the inner edge of the opening in the tip frame.   
     
     
         4 . The system of  claim 1  further comprising:
 a handpiece. 
 
     
     
         5 . The system of  claim 4  comprising:
 a treatment tip coupled in a removable manner with the handpiece, 
 wherein the treatment tip includes the first treatment electrode. 
 
     
     
         6 . The system of  claim 1  further comprising
 a second treatment electrode coupled with the generator, 
 wherein the system controller is configured cause the electromagnetic energy to be provided from the generator to the second treatment electrode with the power profile. 
 
     
     
         7 . The apparatus of  claim 3  further comprising:
 a second treatment electrode. 
 
     
     
         8 . The apparatus of  claim 7  wherein the first treatment electrode and the second treatment electrode are configured to be individually energized to deliver electromagnetic energy. 
     
     
         9 . The apparatus of  claim 3  further comprising:
 a temperature sensor configured to sense a temperature at the treatment electrode. 
 
     
     
         10 . The apparatus of  claim 9  wherein the temperature sensor is a thermistor or a thermocouple. 
     
     
         11 . The apparatus of  claim 3  further comprising:
 a pressure sensor. 
 
     
     
         12 . The apparatus of  claim 3  wherein the first treatment electrode and the tip frame are comprised of flexible materials.
