Claim 0:
1. An electrosurgical system for treating uterine tissue, comprising: an expandable frame for expanding a uterine treatment member between non-expanded and expanded shapes, wherein the uterine treatment member is configured to be coupled to an energy delivery controller for delivering ablative energy to uterine tissue; a handle coupled to the expandable frame to move the uterine treatment member between the non-expanded and expanded shapes, wherein the handle is coupled to the treatment member by a translatable sleeve for actuating the expandable frame to move the treatment member between the non-expanded and expanded shapes, wherein the translatable sleeve includes an indicator mechanism providing an indication of the extent of opening of the treatment member between the non-expanded and expanded shapes, the indicator mechanism configured to track an extent of opening of the treatment member between the non-expanded and expanded shapes based on an axial movement of the indicator mechanism; and a sensor mechanism configured to detect the axial movement of the indicator mechanism and configured to deliver an electrical signal to the energy delivery controller to prevent the energy delivery controller from delivering RF current to the uterine tissue if the treatment member is not opened to a threshold expansion and permitting the energy delivery controller to deliver RF current to the uterine tissue if the treatment member is opened to a threshold expansion.
