Patent ID: 7115123

Claim:
An apparatus for non-invasively treating tissue beneath a skin surface using radiofrequency energy, the apparatus comprising: a handpiece housing; an energy delivery device removably coupled to the handpiece housing, the energy delivery device including a dielectric portion and a conductive portion disposed on the dielectric portion, the conductive portion configured to deliver the radiofrequency energy to the tissue, and the dielectric portion being arranged between the conductive portion and the skin surface such that the radiofrequency energy is transmitted from the conductive portion through the dielectric portion for capacitively coupling with the tissue to perform the non-invasive tissue treatment; a fluid delivery member coupled mechanically to the energy delivery device, the fluid delivery member adapted to deliver cooling fluidic medium to the energy delivery device; and a non-volatile memory mechanically coupled to the energy delivery device, the non-volatile memory configured to store at least one of a duty cycle for controlling the fluid delivery member, a number of times the energy delivery device has been moved relative to the skin surface, or a number of areas treated by the energy delivery device.
