Claim:
1. A system for ablating uterine tissue comprising: a radio frequency (RF) ablation device comprising an elongate member and expandable applicator head coupled to a distal portion of the elongate member, the applicator head comprising a tissue contacting surface and an expandable-contractible carrying member, the carrying member having a contracted state and an expanded state, the contracted state being configured for transcervical insertion and the expanded state being configured for positioning the applicator head in contact with tissue to be ablated, the applicator head including one or more electrodes for ablating endometrial lining tissue of the uterus, the RF ablation device being configured to determine data related to the uterine cavity based on a degree of expansion of the carrying member when in the expanded configuration; and an RF generator, wherein when the RF generator is operably coupled to the RF ablation device, the RF generator is configured to receive the data from the RF ablation device and to provide an RF signal to the RF ablation device based on the data.
