1. 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, including extending the tubular member through a cervical opening and substantially sealing the cervical opening around the tubular member;

    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.
