Abstract

A method and a catheter for passing a therapeutic electric current to, or sensing electric signals from, the body of a patient. The catheter is inserted into the esophagus of the patient, temporarily sealing a space surrounding a portion of the catheter containing one or more electrodes within the esophagus wall. The space is filled with an electrically conductive liquid (electrolyte).
