1. A method, comprising:
- percutaneously introducing an energy delivery element at a distal portion of a treatment device proximate to neural fibers innervating a kidney of a female human patient diagnosed with polycystic ovary syndrome or infertility; and
at least partially disrupting function of the neural fibers innervating the kidney by applying thermal energy to the neural fibers via the energy delivery element,wherein at least partially disrupting the function of the neural fibers innervating the kidney therapeutically treats the diagnosed polycystic ovary syndrome or infertility of the female human patient.

Abstract
Apparatus, systems, and methods for achieving thermally-induced renal neuromodulation by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a treatment device comprising an elongated shaft. The elongated shaft is sized and configured to deliver a thermal element to a renal artery via an intravascular path. Thermally-induced renal neuromodulation may be achieved via direct and/or via indirect application of thermal energy to heat or cool neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers.

9. A method of treating a human patient diagnosed with polycystic ovary syndrome, the method comprising:
-
intravascularly positioning a neuromodulation assembly within a renal blood vessel of the patient and adjacent to sympathetic nerves proximate to the renal blood vessel of the patient; and reducing central sympathetic drive in the patient by delivering energy to the sympathetic nerves via the neuromodulation assembly, wherein reducing central sympathetic drive therapeutically treats the diagnosed polycystic ovary syndrome. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of treating a human patient diagnosed with polycystic ovary syndrome, comprising:
-
intravascularly positioning an electrode within a renal artery of the patient and adjacent to a renal nerve of the patient; and attenuating neural traffic along the renal nerves proximate the renal artery via energy from the electrode, wherein attenuating neural traffic along the renal nerves results in a therapeutically beneficial improvement in one or more physiological conditions associated with the diagnosed polycystic ovary syndrome. - View Dependent Claims (18, 19, 20)
