Abstract
A system for treating uterine tissue comprises an elongated shaft having a proximal end, a distal end, and a longitudinal axis extending between said proximal and distal ends. An energy applicator at the distal end of the elongated shaft is actuatable between a non-expanded shape to be inserted through a patient's cervical canal and an expanded shape to conform to the walls of the patient's uterus. A handle is coupled to a proximal end of the elongated shaft. The handle may include first and second moveable grips coupled to actuate the energy applicator with an upper spring and a lower spring disposed to urge the first and second moveable grips to move apart. An inflatable seal may be located at a distal end of the elongated shaft with a thermally insulating sleeve disposed over the elongated shaft proximal to the inflatable seal. An extension member may be coupled to axially advance and retract the extension member and have a central passage to removably receive an endoscope to enable viewing through the transparent portion of the energy applicator. Alternatively, a tubular sheath may be coupled to the elongated shaft to removably receive an endoscope to enable forward viewing fro…
