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.
Claims31
An electrosurgical 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 extending outward of the outer wall of the housing;
- 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.
2 more elements
A method of treatment, comprising:
- placing an electrosurgical handpiece in contact with a treatment surface;
- causing the electrosurgical handpiece to emit a radio-frequency (RF) signal for a selected duration, wherein the treatment surface is heated in correspondence with the RF signal and the selected duration;
- measuring, with the electrosurgical handpiece, a temperature of the treatment surface;
- communicating the measured temperature to a control system;
- and
- receiving, from the control system, a control signal responsive to the measured temperature.
3 more elements
A method of treatment, comprising:
- causing an electrosurgical handpiece to emit a radio-frequency (RF) signal for a selected duration;
- receiving from the electrosurgical handpiece a temperature of a treatment surface in contact with the electrosurgical handpiece;
- comparing the received temperature to a threshold temperature;
- terminating the RF signal when the received temperature is equal to or higher than the threshold temperature;
- and
- re-engaging or continuing the RF signal emission when the received temperature is lower than the threshold temperature.
