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.

Endocardial mapping catheter with movable electrode

A steerable catheter comprising a flexible elongate tubular member having proximal and distal extremities. A handle is secured to the proximal extremity. The tubular member has a lumen extending therethrough. A mandrel is slidably mounted in the lumen and extends into the distal extremity. A pull wire extends through the tubular member for causing bending of the distal extremity with respect to the mandrel disposed therein.
