Abstract:
1. An apparatus for treating an esophagus, comprising: a generator having a source of RF energy connected to an 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) determine a dimension of the esophagus by measuring an amount of expansion medium delivered to the balloon with a mass-flow meter; (ii) inflate the sizing and treatment catheter to a target pressure; and (iii) deliver sufficient energy to the electrode array for treatment of the esophagus based on the dimension of the esophagus determined by the generator.
