Abstract

Un catéter de ablación por radiofrecuencia que tiene la función de un alambre guía móvil consiste en un soporte eléctrico (1), un cuerpo de catéter (2) y un mango de control (3) ordenados en secuencia. El cuerpo del catéter (2) está provisto allí de una cavidad para el desplazamiento del alambre guía móvil (10) El extremo distal del alambre guía móvil (10) atraviesa el cuerpo del catéter (2) y sobresale del extremo distal del soporte eléctrico (1), un alambre guía blando (12) provisto en el extremo distal del alambre guía móvil (10) siempre se mantiene fuera del soporte eléctrico (1), el extremo proximal del alambre móvil (10) sobresale del extremo proximal del cuerpo del catéter (2) y entra en el mango de control (3), luego, el extremo proximal del alambre móvil (10) se fija a un elemento de control (8) provisto en el mango de control (3) o está fijado a un elemento de control (8) provisto fuera del mango de control (3), Y el alambre guía móvil (10) se empuja para adelante o se retira bajo la acción del elemento de control (8) combinando el alambre guía móvil (10) con el catéter de ablación por radiofrecuencia, el catéter de ablación por radiofrecuencia que tiene la función de un alambre guía móvil (10) ya no requiere la acción de retirar el alambre guía móvil (10) del catéter de ablación por radiofrecuencia, simplificando la operación con el alambre guía móvil (10), y facilitando el movimiento del catéter de ablación por radiofrecuencia durante la intervención quirúrgica.
