Patent Images
1. Apparatus for renal neuromodulation, the apparatus comprising:
- a device comprising an electrode, wherein the electrode is configured for percutaneous placement proximate a renal vasculature in a patient;
an electric field generator operatively coupled to the electrode; and
a controller configured to operate instructions that cause the electric field generator to deliver an electric field via the electrode to a renal nerves while the electrode is located proximate the renal vasculature.

Abstract
Methods and apparatus are provided for renal neuromodulation using a pulsed electric field to effectuate electroporation or electrofusion. It is expected that renal neuromodulation (e.g., denervation) may, among other things, reduce expansion of an acute myocardial infarction, reduce or prevent the onset of morphological changes that are affiliated with congestive heart failure, and/or be efficacious in the treatment of end stage renal disease. Embodiments of the present invention are configured for percutaneous intravascular delivery of pulsed electric fields to achieve such neuromodulation.
