Abstract
A catheter for sensing electrical events about a selected annulus region of the heart and for treating tissue in the selected annulus region has a handle assembly, and a shaft having a proximal end coupled to the handle assembly. The catheter also has a mapping element provided adjacent its distal end, and an ablation element positioned spaced apart along the shaft from the mapping element. The mapping element is first positioned at the desired treatment location in the selected annulus region and the desired treatment location is mapped. The ablation element is then positioned at the desired treatment location by moving the mapping element away from the desired treatment location, and the desired treatment location is ablated.
