Abstract

Un catéter para denervación incluye un cuerpo del catéter que se extiende en una dirección tal que tiene un extremo proximal y un extremo distal, y que tiene un espacio interno formado a lo largo de la dirección longitudinal del mismo, un miembro movible configurado para ser movible en el espacio interno del cuerpo del catéter a lo largo de la dirección longitudinal del cuerpo del catéter, un miembro operante que tiene un extremo distal conectado al miembro movible para mover el miembro movible, una pluralidad de miembros de soporte que tienen un extremo conectado al miembro movible y configurados de tal manera que el otro extremo de los mismos se mueva próximo o más alejado del cuerpo del catéter de acuerdo con el movimiento del miembro movible, una pluralidad de electrodos provistos respectivamente al otro extremo de la pluralidad de miembros de soporte para generar calor, y un hilo conductor respectivamente conectado eléctricamente a la pluralidad de electrodos para brindar un pasaje de suministro de energía para la pluralidad de electrodos, donde el hilo conductor tiene una región variable cuya longitud es cambiable de tal manera que un extremo proximal de la región variable se fija a un lado del cuerpo del catéter y un extremo distal de la región variable se fija al miembro movible.A denervation catheter includes a catheter body that extends in a direction such that it has a proximal end and a distal end, and that has an internal space formed along the longitudinal direction thereof, a movable member configured to be movable. in the internal space of the catheter body 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 an end connected to the movable member and configured such that the other end thereof moves closer or further away from the catheter body according to the movement of the movable member, a plurality of electrodes provided respectively to the other end of the plurality of support members for generate heat, and a conductive wire respectively electrically connected to the plurality of electrodes to provide give a power supply passage for the plurality of electrodes, where the conductive wire has a variable region whose length is changeable such that a proximal end of the variable region is fixed to one side of the catheter body and a distal end of The variable region is fixed to the movable member.
