1. A device for mapping and ablating the renal nerves distributed on the renal artery, comprising a guide catheter, a mapping-ablation catheter, a handle and a connector, wherein
said guide catheter has at least one lumen and a distal end with adjustable curvature;
said mapping-ablation catheter is housed in the at least one lumen of the guide catheter and has a distal end that comprises one or more electrodes and one or more detecting devices, said distal end of the mapping-ablation catheter is curved and can be extended out of or retracted into the guide catheter and is rotatable along the central axis of the open end of the guide catheter;
said handle connects the guide catheter and mapping-ablation catheter and comprises one or more controlling components, said controlling components are for controlling the movement of the guide catheter and mapping-ablation catheter; said handle further comprises an interlock, said interlock prevents said mapping-ablation catheter from: i) rotating when extending or retracting into said guide catheter; ii) extending or retracting into said guide catheter when said one or more controlling components are controlling said mapping-ablation catheter to rotate around the central axis of the open end of the guide catheter; and
said connector is designed to supply energy to the one or more electrodes.
