MEDICAL DEVICES FOR RENAL NERVE ABLATION

摘要

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.
