Abstract
A cardiac ablation catheter has an energy emitting surface for thermally destroying tissue. The surface normally presents a compact, low profile for introduction into the heart. Once introduced, the energy emitting surface can be significantly enlarged. The enlarged surface emits ablation energy sufficient to create a lesion that is significantly larger in terms of volume and geometry than the surface's initial low profile would provide.
