Methods for thermally-induced renal neuromodulation
First Claim
1. A method for thermally affecting renal nerves proximate renal vasculature of a human patient, the method comprising:
- delivering a catheter having an infusion needle to a renal blood vessel of the patient and adjacent the renal nerves;
delivering a thermal fluid to the renal nerves via the infusion needle;
thermally modulating a function of the renal nerves via the thermal fluid; and
removing the catheter from the patient after delivering the thermal fluid to conclude the therapy.

Abstract
Methods and apparatus are provided for thermally-induced renal neuromodulation. 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. In some embodiments, parameters of the neural fibers, of non-target tissue, or of the thermal energy delivery element, may be monitored via one or more sensors for controlling the thermally-induced neuromodulation. In some embodiments, protective elements may be provided to reduce a degree of thermal damage induced in the non-target tissues.
