RENAL NERVE MODULATION CATHETER DESIGN

摘要

Systems for nerve and tissue modulation are disclosed. An example system may an elongate shaft including an expandable frame coupled to the shaft adjacent to a distal end of the shaft. The frame may include a plurality of electrically conductive regions for emitting an electrical current comprising at least a first electrically conductive region and a second electrically conductive region. The system may further include a ground pad and a control unit electrically coupled to the plurality of electrically conductive regions and the ground pad. The control and power unit is configured to operate in unipolar mode and bipolar mode during the same procedure.
