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.

Catheter apparatuses having expandable mesh structures and associated systems and methods for intravascular renal neuromodulation are disclosed herein. A catheter treatment device includes an expandable mesh structure configured to position an energy delivery element in contact with a renal artery via an intravascular path. The mesh structure can assume an expanded configuration 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. A collapsed configuration may facilitate insertion and/or removal of the catheter or repositioning of the energy delivery element within the renal artery.

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:
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 including a therapeutic assembly having a central axis and a distal portion and a proximal portion axially spaced along the central axis, the therapeutic assembly including a core element extending from the proximal portion to the distal portion and a heating element disposed along at least a portion of a length of the core element. An energy source provides electrical current to the heating element to cause the heating element to increase in temperature.
