WALL-SPARING RENAL NERVE ABLATION CATHETER WITH SPACED ELECTRODE STRUCTURES

摘要

Systems and methods for performing tissue modulation are disclosed. A nerve modulation assembly may include a guide sheath having a proximal end, a distal end, and a lumen extending therebetween. An actuation member, also having a proximal end and a distal end, extends along a central elongate axis disposed within the lumen. Further, the ablation member disposed at the distal end of the actuation member is configured to be actuated from the proximal end of the guide sheath. In particular, the ablation member includes a radiofrequency based electrode member, and an insulation member disposed circumferentially around the radiofrequency based electrode member.
