Abstract:
1. A system for treating a tissue region at or near a sphincter comprising an electrode structure comprising a plurality of tissue-piercing energy delivery devices for forming a lesion pattern in submucosal tissue at or near the sphincter, a housing, a generator integrated in the housing to generate energy capable of heating tissue and adapted to be coupled to the electrode structure to apply the energy to the tissue region, a pumping mechanism integrated in the housing and adapted to be attached to tubing to dispense cooling fluid from a source to the tissue region, a controller integrated in the housing and coupled to the generator and the pumping mechanism, to enable control of the generator in supplying energy to the electrode structure to raise tissue temperature in the tissue region, in concert with operation of the pumping mechanism in supplying cooling fluid to the tissue region to control the tissue temperature, and a user interface including command inputs coupled to the controller, the command inputs including at least one generator control input for receiving from an operator an input affecting operation of the generator and at least one pump control input for receiving from an operator an input affecting operation of the pumping mechanism, the user interface including a first visual image displayed in association with the generator control input and a second visual image displayed in association with the pump control input, the first visual image being different than the second visual image, the first visual image further including a first visual indication of a tissue temperature condition adjacent each of the plurality of tissue-piercing energy delivery devices as energy is supplied to the electrode structure and, simultaneous with the first visual indication, a second visual indication of a running time condition reflecting a time period elapsed and/or remaining for supplying energy to the electrode structure relative to a targeted treatment period.
