Abstract A swallowable electrode or an esophageal catheter are formed with a porous or roughened region capable of receiving a cream or jell form of topical anesthetic. The anesthetic can be covered with a dissolvable medium. Located on each side of the anesthetic is a metal conductor coupled to a flexible wire extending from the device. Upon positioning of the metal members in an individual's esophagus, adjacent a posterior heart surface, the protective medium dissolves exposing the topical anesthetic to portions of the esophagus adjacent to the two conducting members. A lumen in the catheter can be provided to deliver the anesthetic to the esophagus. The exposed anesthetic can be absorbed by the adjacent region of the esophagus thereby providing for more comfortable esophageal cardiac pacing.
