Abstract
A multi-electrode mapping catheter for endocardial contact mapping of a heart chamber includes an expandable basket movable between a contracted configuration and a pre-shaped deployed configuration, the expandable basket including a plurality of flexible splines. Each spline includes a flex circuit and an electrode for mapping. A catheter shaft extending from the basket includes a lumen formed therethrough for receiving an ablation catheter for placement within the expandable basket. Each flex circuit includes a conductor that directly connects the proximal end of the catheter shaft to an electrode as a single continuous piece. In another embodiment, a shaft flex circuit extends along the length of the shaft and is electrically connected to a basket flex circuit. The expandable basket maintains the electrodes in direct contact with the wall of the heart while accommodating wall motion of the beating heart during mapping and can continually map while ablating.
