ABSTRACT:
An apparatus for mapping the wall of a chamber of the heart having blood therein. The apparatus includes a flexible elongate tubular member having proximal and distal extremities and at least one lumen extending therethrough. A basket assembly is carried by the distal extremity of the flexible elongate tubular member and is movable between contracted and expanded positions. The basket assembly has a plurality of elongate flexible circumferentially spaced-apart arms with proximal and distal extremities. A plurality of longitudinally spaced-apart electrodes are carried by each arm for engaging the wall of the heart. Spacing members coupled to the arms and extending between the arms are provided for establishing a desired substantially uniform circumferential spacing between the arms when the basket assembly is in expanded position in engagement with the wall of the heart. Openings are provided between the arms and the spacing members through which blood can flow.
