Featured is a catheter device for ablating tissue that includes an elongated body member having a distal portion and a deflection mechanism operably coupled to the distal portion so as to cause the distal portion to deflect with respect to a longitudinal axis of the elongated body member. Such a catheter device also includes a guide member and a guiding mechanism that is coupled to the elongated body member and is configured so as to guide the guide member. The guiding mechanism includes an exit portion from which the guide member exits during deployment. The exit portion is disposed with respect to the distal portion end so the distal portion deflects from and with respect to the guide member as well as rotating about the guide member. Also featured are systems and methods related thereto.
L'invention concerne un dispositif de cathéter permettant d'ablater un tissu. Ledit cathéter comprend un élément de corps allongé présentant une partie distale et un mécanisme de déflexion accouplé fonctionnel à la partie distale de manière à amener la partie distale à défléchir par rapport à un axe longitudinal de l'élément de corps allongé. Ledit dispositif de cathéter comprend également un élément de guidage et un mécanisme de guidage qui est accouplé à l'élément de corps allongé et conçu de manière à guider l'élément de guidage. Le mécanisme de guidage comprend une partie de sortie à partir de laquelle l'élément de guidage sort lors du déploiement. La partie de sortie est située par rapport à l'extrémité de la partie distale de sorte que la partie distale défléchit à partir de et par rapport à l'élément de guidage et tourne autour de l'élément de guidage. L'invention concerne également des systèmes et des méthodes associées.
