A system for nerve modulation includes a first elongate element (14) having a distal end and a proximal end and having a helical guide (26) having a proximal end and a distal end. The system also includes a second elongate element (12) having a distal end and a proximal end and having a nerve modulation element (22) proximate the distal end. A sheath (16) is disposed about both the first and second elongate elements.
