1. An ablation catheter, comprising:
an elongate body having proximal and distal ends with an inner lumen extending there between; and
an expandable end effector extending distally beyond the distal end of the elongate body and configured to deliver energy to tissue, the expandable end effector having first, second, and third configurations, wherein in the first configuration, the expandable end effector is substantially linear and extends along a longitudinal axis extending through the elongate body and expandable end effector and is configured to form a single point lesion or a linear lesion, in the second configuration the expandable end effector extends radially outward from the longitudinal axis, and in the third configuration a portion of the expandable end effector faces distally and extends in a plane substantially perpendicular to the longitudinal axis.
