Abstract
An endocardial mapping catheter for introduction into a chamber of a heart formed by a wall. The flexible elongate tubular member has proximal and distal extremities and extends along a longitudinal axis. A plurality of longitudinally-extending spaced-apart members are carried by the distal extremity of the flexible elongate tubular member and have proximal extremities and interconnected distal extremities. Certain of the plurality of longitudinally-extending members are arms of a basket-like assembly and are movable between contracted positions and expanded positions in which the arms bow outwardly from the longitudinal axis. A plurality of longitudinally spaced-apart electrodes are carried by each of the arms. Electrical conductors extend through the flexible elongate tubular member and are connected to the electrodes for performing electrical functions with respect to the electrodes. At least one additional electrode is slidably mounted on one of the longitudinally-extending members.
