Abstract
Helical push wire electrodes are provided. The electrodes may create a continuous helical lesion. One or more electrodes may wind around a support section and create a set of helixes having fixed ends and hitches. Pushing or pulling an end of the electrode transforms the electrodes between a delivery configuration and a deployed configuration such that the set of helixes expand or contract axially. Different portions of the electrodes may be surrounded by sleeves. The sleeves may regulate how the wires transform and provide insulation. Various insulation configurations of the electrodes may provide creations of discrete lesions, efficient energy delivery and reduced power consumption.
