ABSTRACT:
A system for measuring physiologic characteristics for treating abnormal mucosa in the esophagus comprises a sizing device having an inflatable balloon on a distal end of a catheter that is inflated with an expansion medium to expand the balloon to engage the wall of the esophagus so that the internal cross-section can be calculated or measured. The sizing device may also include an infusion source for delivering the expansion medium and means for measuring the amount and pressure of the expansion medium inside the catheter. The system also comprises one or more energy delivery devices for injuring or ablating the esophageal tissue.
