Abstract
Electrosurgical systems and components thereof configured to deliver RF energy to a target site of a human or other animal patient with selectable RF energy delivery profiles, temperature sensors and controls, and/or electrodes configured to more uniformly or effectively delivery energy to target tissue.
Claims3
An electrosurgical handpiece for non-invasive aesthetic treatments, the handpiece comprising:
- a housing for a temperature sensor, wherein the housing defines a first patient-contact surface, an inner surface positioned opposite the first patient-contact surface, and an outer wall extending transversely relative to the first patient-contact surface;
- a temperature sensor thermally coupled with the inner surface of the housing;
- an energizable electrode defining a second patient-contact surface positioned outward of the first patient contact surface, wherein the energizable electrode comprises an inner first layer and a second layer coating the inner first layer and defining the second patient contact surface, wherein a thermal mass of the energizable electrode is larger than a thermal mass of the temperature sensor;
- and
- an insulator positioned between the energizable electrode and the housing for the temperature sensor to inhibit thermal conduction between the energizable electrode and the housing for the temperature sensor.
