Abstract
A radio-frequency electrode and handpiece that is specially configured to provide a reasonably uniform electric field distribution at the skin surface of a patient being treated to improve the skin appearance. Harmful burning is avoided by sensing and displaying skin and electrode temperature. Continuous electrode contact and electrode motion relative to the skin is achieved by providing a rolling cap over a dome-shaped electrode, and by spring biasing the electrode for up and down motion, and by providing side-to side motion of the electrode manually or by motor.
