Title
(EN) APPARATUS AND METHOD FOR SEPTAL PUNCH
(FR) APPAREIL ET MÉTHODE DE PERFORATION SEPTALE
Abstract
(EN)
In some embodiments, a method includes a shaft (320) having a side catheter guide (330) attached thereto via a guide coupler (340) into an inferior vena cava and a superior vena cava such that the guide coupler (340) is disposed in a right atrium, and applying a distal force to a proximal portion of the side catheter guide (330) such that a distal end of the side catheter guide (330) deflects laterally about the guide coupler (340) towards a septum. The method further includes extending a side catheter (360) that is disposed within the side catheter guide (330) distally from the side catheter guide (330) towards and into contact with the septum. The method further includes, with the side catheter (360) in contact with the septum, extending a septum penetrator (370) that is slidably disposed within the side catheter (360) distally from the side catheter (360) such that the septum penetrator (370) pierces the septum.

Dans certains modes de réalisation, une méthode comprend un arbre (320) ayant un guide de cathéter latéral (330) fixé à celui-ci par l'intermédiaire d'un coupleur de guidage (340) dans une veine cave inférieure et une veine cave supérieure de telle sorte que le coupleur de guidage (340) est disposé dans une oreillette droite, et appliquant une force distale à une partie proximale du guide de cathéter latéral (330) de telle sorte qu'une extrémité distale du guide de cathéter latéral (330) dévie latéralement autour du coupleur de guidage (340) vers un septum. La méthode comprend en outre l'extension d'un cathéter latéral (360) qui est disposé à l'intérieur du guide de cathéter latéral (330) de manière distale depuis le guide de cathéter latéral (330) vers et en contact avec le septum. La méthode comprend en outre, avec le cathéter latéral (360) en contact avec le septum, l'extension d'un pénétrateur de septum (370) qui est disposé de façon coulissante à l'intérieur du cathéter latéral (360) de façon distale depuis le cathéter latéral (360) de telle sorte que le pénétrateur de septum (370) perce le septum.
