Abstract
Catheters, systems, and methods for achieving renal neuromodulation by intravascular access. A catheter has an energy delivery device positionable in a renal blood vessel and being transformable between a radially constrained low-profile state and a self-expanded deployed state. The energy delivery device includes a first electrode array spaced longitudinally from and flexibly connected to a second electrode array, the arrays being sized and shaped so that the electrode regions contact an interior wall of the renal blood vessel when the energy delivery device is in the deployed state. The electrode regions are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function or of vascular structures that feed or perfuse the neural fibers.
