Abstract
A catheter probe comprising a flexible elongate tubular member having proximal and distal extremities. An expandable assembly capable of moving from a contracted position to an expanded position is secured to the distal extremity of the flexible elongate tubular member and is formed from at least two elongate members movable between contracted and expanded positions. The elongate members have extremities which are joined so that the elongate members extend at an angle relative to each other to form a vee therebetween. A plurality of longitudinally and radially spaced-apart electrodes are carried by the expandable assembly so that they can be moved into engagement with the wall of the heart when the expandable assembly is expanded into the expanded position. Electrical conductors extend through the elongate tubular member and are connected to the electrodes for performing electrical functions with respect to the electrodes. An elastomeric material is adhered to the joined extremities of the elongate members and is disposed within the vee for inhibiting the formation of thrombus on the elongate members while the expandable assembly is disposed within the blood of the heart.
