US Patent 7481809 Handpiece with RF electrode and non-volatile memory

An RF device includes a support structure coupled to an RF electrode that has conductive and dielectric portions. A cooling member is coupled to the support structure and is configured to cool a back surface of the RF electrode. The cooling member is distanced from the back surface of the RF electrode. A memory is coupled to the RF electrode. The memory is configured to store information to facilitate operation of at least one of the RF electrode, the cooling member and an RF energy source.
