Renal nerve modulation devices and methods for making and using renal nerve ablation devices are disclosed. An example renal nerve modulation device may include elongate catheter shaft having a distal portion. One or more tubular shafts may be disposed within the catheter shaft. Each of the tubular shafts may include a proximal portion, a distal portion, and a lumen extending therebetween. Each of the tubular shafts may also include a slotted portion having a plurality of slots formed therein. The slots may define a preferential zone of bending in a predetermined direction. Each of the tubular shafts may also an actuation member that is configured to shift the tubular shaft between a first configuration and a bent configuration. An ablation member may be coupled to the distal portion. |
