Catheter for denervation

A catheter for denervation, comprising:

• a catheter body extending in one direction to have a proximal end and a distal end and having an inner space formed along a 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 and fixed to a terminal of the catheter body and another end connected and fixed 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,
• wherein at least one of the catheter body and the movable member is connected and fixed to at least two of the plurality of support members at points which are spaced apart from each other by a predetermined distance in the longitudinal direction of the catheter body,
• wherein at least one of the catheter body and the movable member has stepped surfaces to which the plurality of support members are connected and fixed,
• wherein at least two of the plurality of support members are connected and fixed to different stepped surfaces of the at least one of the catheter body and the movable member such
• that connection points of the at least two of the plurality of support members with respect to the catheter body are spaced apart from each other by a predetermined distance in the longitudinal direction of the catheter body, and/or
• that connection points of the at least two of the plurality of support members with respect to the movable member are spaced apart from each other by a predetermined distance in the longitudinal direction of the catheter body.
