Systems and methods deploy an electrode structure in contact with the tissue region. The electrode structure carries a sensor at a known location on the electrode structure to monitor an operating condition. The systems and methods provide an interface, which generate an idealized image of the electrode structure and an indicator image to represent the monitored operating condition in a spatial position on the idealized image corresponding to the location of the sensor on the electrode structure. The interface displays a view image comprising the idealized image and indicator image. The systems and methods cause the electrode structure to apply energy to heat the tissue region while the view image is displayed on the display screen.
A system for treating gastroesophageal reflux disease comprising a radiofrequency generator, a controller, a fluid delivery device and a treatment device, the fluid delivery apparatus delivering fluid through the treatment device, the treatment device including a basket assembly and a plurality of electrodes for delivering radiofrequency energy to tissue to treat the lower esophageal sphincter for treating gastroesophageal reflux disease, the electrodes extendable from the basket assembly and spaced apart to form a multiple electrode geometry, the treatment device having a first sensor for measuring temperature adjacent each electrode and a second sensor for measuring temperature of a tip of each electrode, the generator applying bursts of radiofrequency energy through selected electrodes to derive an impedance value for the selected electrode to indicate whether the selected electrode is in desired contact with tissue, a graphical user interface coupled to the controller, the graphical user interface including an electrode icon spatially modeling the multiple electrode geometry of the electrodes of the treatment device to visually indicate measured temperature values, the measured temperature values displayed adjacent the associated electrode to display the temperature value associated with the electrode throughout the procedure.
A system for treating gastroesophageal reflux disease comprising a generator and a controller, the controller having an input port to receive a treatment device having a plurality of electrodes for applying energy to the lower esophageal sphincter to treat gastroesophageal reflux disease, a fluid delivery device including a pump for delivering fluid to the tissue to regulate temperature of the tissue, the pump controllable in response to measured tissue temperature, a graphical user interface coupled to the controller, the graphical user interface displaying an array corresponding to the spacial relationship of the electrodes, the array arranged in a spoke like fashion with each electrode represented by a spoke and a measured temperature value indicated along the spoke displaying the represented electrode to display the temperature value associated with the electrode throughout the procedure.
