Abstract: A catheter for denervation includes a catheter body extending in one direction to have a proximal end and a distal end and having an inner space formed along the longitudinal direction thereof, a movable member provided at the distal end of the catheter body to be movable along the longitudinal direction of the catheter body, an operating member having a distal end connected to the movable member to move the movable member, a plurality of support members having one end connected to a terminal of the catheter body and the other end connected to the movable member, wherein when the movable member moves to decrease a distance between the terminal of the catheter body and the movable member, at least a partial portion of the plurality of support members is bent so that the bending portion moves away from the catheter body, a plurality of electrodes respectively provided at the bending portion of the plurality of support members to generate heat, and a lead wire respectively electrically connected to the plurality of electrodes to give a power supply path for the plurality of electrodes.

Abstract translation: 用于去神经支配的导管包括导管主体，所述导管主体在一个方向上延伸以具有近端和远端，并且具有沿着其纵向方向形成的内部空间;可移动构件，设置在导管主体的远端处， 导管主体的纵向方向;操作构件，其远端连接到可移动构件以移动可移动构件;多个支撑构件，其一端连接到导管主体的端子，另一端连接到可动构件 其特征在于，当所述可移动部件移动以减小所述导管主体的端子与所述可动部件之间的距离时，所述多个支撑部件的至少一部分被弯曲，使得所述弯曲部分远离所述导管主体移动， 分别设置在多个支撑构件的弯曲部分处以产生热量的电极，以及引线分别电连接 连接到多个电极以给出用于多个电极的电源路径。
