摘要：
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.
