Methods for catheter-based renal denervation
First Claim
1. A method for catheter-based renal neuromodulation, the method comprising:
- positioning a catheter having a therapeutic element within a renal artery of a human patient; and
reducing neural traffic to and/or from a kidney of the patient via the therapeutic element,wherein reducing the neural traffic to and/or from the kidney therapeutically treats a diagnosed condition or disease associated with cardio-renal function of the patient.

Abstract
Methods and apparatus are provided for treating end-stage renal disease, e.g., via a pulsed electric field, via a stimulation electric field, via localized drug delivery, via high frequency ultrasound, via thermal techniques, etc. Such neuromodulation may effectuate irreversible electroporation or electrofusion, necrosis and/or inducement of apoptosis, alteration of gene expression, action potential attenuation or blockade, changes in cytokine up-regulation and other conditions in target neural fibers. In some embodiments, neuromodulation is applied to neural fibers that contribute to renal function. In some embodiments, such neuromodulation is performed in a bilateral fashion. Bilateral renal neuromodulation may provide enhanced therapeutic effect in some patients as compared to renal neuromodulation performed unilaterally, i.e., as compared to renal neuromodulation performed on neural tissue innervating a single kidney.

18. A method for catheter-based renal denervation, the method comprising:
-
positioning a catheter having a therapeutic element within a renal artery of a human patient; and ablating nerves that innervate a kidney of the patient via the therapeutic element, wherein ablating the nerves results in a therapeutically beneficial reduction in blood pressure in the patient. - View Dependent Claims (19, 20, 21, 22, 23, 24)
