Abstract
This invention provides a device for mapping and ablating the renal nerves distributed on renal artery, having a guide catheter, a mapping-ablation catheter, a handle and a connector. The guide catheter has at least one lumen and a distal end with adjustable curvature. The mapping-ablation catheter is housed in one of the lumens of the guide catheter and its distal end has one or more electrodes and one or more detecting devices. The distal end of the mapping-ablation catheter is curved, rotatable, and can be extended out of or retracted into the guide catheter. The handle connects the guide catheter and mapping-ablation catheter, and has one or more controlling components for controlling the movement of the guide catheter and mapping-ablation catheter. The connector is designed to supply energy to the electrodes.
