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, a shaft having a proximal end coupled to the handle assembly, a first expandable member provided at the distal end of the shaft, and a second expandable member positioned adjacent to, but spaced apart from, the first expandable member. The second expandable member has an ablation element that emits energy to a radially surrounding area to ablate tissue

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, a shaft having a proximal end coupled to the handle assembly, a first expandable member provided at the distal end of the shaft, and a second expandable member positioned adjacent to, but spaced apart from, the first expandable member. The second expandable member has an ablation element that emits energy to a radially surrounding area to ablate tissueFile in questo prodotto:
