Claim:
1. An apparatus for treating an esophagus, comprising: a generator having a source of RF energy connected to a generator electrical connector and a pump connected to a generator pneumatic connector; and a sizing and treatment catheter having a proximal end and a distal end, an electrical connector configured for attachment to the generator electrical connector and a pneumatic connector on the proximal end configured for attachment to the generator pneumatic connector and a balloon on the distal end of the catheter in communication with the pneumatic connector and an electrode array on an exterior surface of the balloon in communication with the electrical connector; wherein, when the sizing and treatment catheter is connected to the generator electrical connector and the generator pneumatic connector, the generator is configured to: (i) measure an internal pressure of the balloon; (ii) inflate the balloon with an expansion medium until the internal pressure is equal to a predetermined target pressure; (iii) measure the expansion medium delivered to the balloon with a mass-flow meter until the predetermined target pressure is reached; (iv) determine a dimension of the esophagus based on the amount of expansion medium in the balloon at the predetermined target pressure; and (v) deliver energy to the electrode array.
