Moisture transport system for contact electrocoagulation

A method of ablating walls of a uterus using an ablation device, the ablation device comprising a tubular member coupled to a working end, the working end comprising a first electrode and a second electrode, the method comprising:

• positioning the first electrode within the uterus;
• delivering ablation energy through the first and second electrodes to the walls of the uterus, wherein the delivering step causes moisture to be released from the walls;
• and
• removing the released moisture through a continuously open flow path through the tubular member during the delivering step, wherein the first and second electrodes are bipolar electrodes, and wherein the delivering step delivers RF energy to the bipolar electrodes.
