Renal neuromodulation methods and systems for treatment of hyperaldosteronism

A method, comprising:

• percutaneously introducing a neuromodulation assembly at a distal portion of a treatment device proximate to neural fibers innervating a kidney of a human patient diagnosed with hyperaldosteronism;
• partially disrupting function of the neural fibers by applying thermal energy to the neural fibers via the neuromodulation assembly;
• and
• removing the neuromodulation assembly from the patient after treatment;
• wherein partial disruption of the function of the neural fibers therapeutically treats the diagnosed hyperaldosteronism.

A method for treating a human patient with diagnosed hyperaldosteronism, the method comprising:

• positioning an energy delivery element of a renal denervation catheter within a renal blood vessel of the patient and adjacent to post-ganglionic neural fibers that innervate a kidney of the patient;
• and
• at least partially ablating a renal nerve of the patient via the energy delivery element,
• wherein at least partially ablating the renal nerve results in a therapeutically beneficial improvement in one or more physiological conditions associated with hyperaldosteronism of the patient.
