Zusammenfassung:A deflectable catheter (200) for guiding surgical tools that are passed therethrough includes a tubular structure (215), a sensor coil (213) disposed around an end portion of the tubular structure and a pull wire assembly (211, 212), which is coupled to the end portion of the tubular structure and is configured to cause a distal portion of the tubular structure to deflect when the pull wire assembly is operated. The catheter further includes a coil wire (210) disposed around a portion of the tubular structure and configured to restrain the pull wire. Un cathéter déformable (200) pour guider des outils chirurgicaux qui sont passés à travers celui-ci comprend une structure tubulaire (215), une bobine de capteur (213) disposée autour d'une partie d'extrémité de la structure tubulaire et un ensemble fil de traction (211, 212), qui est couplé à la partie d'extrémité de la structure tubulaire et est conçu pour amener une partie distale de la structure tubulaire à se déformer lorsque l'ensemble fil de traction est actionné. Le cathéter comprend en outre un fil de bobine (210) disposé autour d'une partie de la structure tubulaire et configuré pour retenir le fil de traction.
