Abstract
A method and apparatus for treatment of heart failure, hypertension and renal failure by stimulating the renal nerve. The goal of therapy is to reduce sympathetic activity of the renal nerve. Therapy is accomplished by at least partially blocking the nerve with drug infusion or electrostimulation. Apparatus can be permanently implanted or catheter based.

44. A method of treating cardio-renal disease, comprising:
-
positioning an electrode proximate to neural fibers that contribute to renal function; and
generating an electric field from the electrode such that at least a portion of the neural fibers are in the electric field, wherein the electric field alters neural function of the neural fibers. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82)

83. An apparatus for treating a patient, comprising:
-
an electrode configured to be percutaneously positioned in the patient so that the electrode is proximate to neural fibers that contribute to renal neural function; and
an energy generator operatively coupled to the electrode, wherein the energy generator comprises a controller and instructions that cause the controller to generate an electric field via the electrode that overlaps a portion of the neural fibers and alters neural activity along the neural fibers. - View Dependent Claims (84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97)
