ABSTRACT:
An apparatus for mapping the wall of a chamber of the heart. The apparatus includes a flexible elongate tubular member having proximal and distal extremities and at least one lumen extending therethrough. A plurality of longitudinally and radially spaced-apart electrodes are provided. An expandable device is carried by the distal extremity of the flexible elongate tubular member and is movable between a contracted position and an expanded position. The electrodes are mounted on the expandable device so that when the expandable device is moved to its expanded position in the chamber of the heart the electrodes are moved into engagement with the wall forming the chamber of the heart. Leads for conducting electrical energy are in contact with the electrodes and extend into the flexible elongate tubular member. An electrical apparatus is connected to the leads for performing electrical functions with respect to the electrodes and includes at least one semiconductor device carried by the distal extremity of the flexible elongate tubular member in close proximity to the expandable device.
