ABSTRACT:
Endocardial catheter for introduction into a lumen of a vessel leading to a chamber formed by the wall of a heart of a patient comprising a flexible elongate tubular member having proximal and distal extremities and having a longitudinal axis. An electrode having radially spaced apart electrode portions is provided. An expandable device movable between contracted and expanded positions is secured to the distal extremity of the flexible elongate tubular member. The expandable device has an outer surface upon which the electrode is mounted. An elongate element is secured to the expandable device for moving the expandable device to the expanded position to thereby move the electrode into engagement with the wall forming the chamber of the heart. An additional electrode is mounted on the flexible elongate tubular member in relatively close proximity to the first named electrode. Leads are connected to the electrode and to the additional electrode and extend to the proximal extremity of the flexible elongate member.
