Catheter assemblies for neuromodulation proximate a renal artery bifurcation and associated systems and methods are disclosed herein. A catheter assembly configured in accordance with a particular embodiment of the present technology can include a shaft having a proximal portion, a distal portion, and two therapeutic arms extending from the distal portion. The shaft can be configured to deliver the distal portion to a treatment site proximate a branch point or bifurcation in a renal blood vessel. The therapeutic arms can include energy delivery elements that are configured to deliver the therapeutically-effective energy to renal nerves proximate the branch point.

Catheter assemblies for neuromodulation proximate a bifurcation of a renal artery and associated systems and methods

Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function or of vascular structures that feed or perfuse the neural fibers.

Catheter apparatuses having multi-electrode arrays for renal neuromodulation and associated systems and methods

The present disclosure relates to devices, systems and methods for evaluating the success of a treatment applied to tissue in a patient, such as a radio frequency ablative treatment used to neuromodulate nerves associated with the renal artery. A system monitors parameters or values generated during the course of a treatment. Feedback provided to an operator is based on the monitored values and relates to an assessment of the likelihood that a completed treatment was technically successful. In other embodiments, parameters or values generated during the course of an incomplete treatment (such as due to high temperature or high impedance conditions) may be evaluated to provide additional instructions or feedback to an operator.
