Abstract: Medical devices and methods for making and using the same are disclosed. An example medical device may include a medical device for renal nerve ablation. The medical device may include an elongate shaft having a distal region. An expandable member may be coupled to the distal region. A plurality of electrodes may be coupled to the expandable member and a single conductive member may be coupled to each electrode. Where one of the plurality of electrodes is active, the remaining electrodes may be inactive and act as ground or return electrodes. The electrode of the plurality of electrodes that is active may change over time.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter shaft. An expandable balloon may be coupled to the catheter shaft. The balloon may be capable of shifting between a folded configuration and an expanded configuration. A support structure may be coupled to the balloon. The support structure may be capable of shifting the balloon toward the folded configuration. A plurality of elongate flexible electrode assemblies may be disposed on the balloon. The elongate flexible electrode assemblies may be oriented at an angle relative to a longitudinal axis of the balloon.
