摘要： 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.

摘要： 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.
