Definitions

  • the present invention has been made in consideration of such problems, and in the case of adjusting the axial position of the stent graft, it is possible to reduce the possibility of damaging the inner wall of the blood vessel and to shift the axial position when the stent graft is expanded.
  • An object of the present invention is to provide a stent graft delivery device capable of suppressing the above.
  • the first slider and the second slider have a first shape in which axial displacement with respect to the shaft is allowed and a second shape in which axial displacement with respect to the shaft is restricted. It is elastically deformable, and the fixing mechanism includes a flexible driving member that spans between the first slider and the second slider, and the first slider and the second slider are moved by the driving member. The first slider and the second slider may be deformed from the first shape to the second shape by being pressed toward the shaft.
  • FIG. 7 is a partially omitted cross-sectional view of a centering mechanism in a movement-permitted state of a stent graft delivery device according to a second embodiment of the present invention and its peripheral portion. It is a partially omitted sectional view of the centering mechanism in the movement restricted state of the stent graft delivery device according to the second embodiment of the present invention and its peripheral portion.
  • 11A is a cross-sectional view taken along the line XIA-XIA in FIG. 9, and FIG. 11B is a cross-sectional view taken along the line XIB-XIB in FIG. FIG.
  • FIG. 9 is a partially omitted cross-sectional view of the centering mechanism 80 of the stent-graft delivery device 10B (hereinafter, also simply referred to as “delivery device 10B”) according to the second embodiment and its peripheral portion.
  • the delivery device 10B differs from the delivery device 10A according to the first embodiment mainly in that it does not include the above-described detachment mechanism 22 and includes a fixing mechanism 82.
  • the configuration of the delivery device 10B is the same as that of the delivery device 10A unless otherwise specified below.
  • the delivery device 10B includes the fixing mechanism 82, thereby displacing the sheath 16 in the proximal direction and expanding the centering mechanism 80, and then displacing the sheath 16 in the distal direction again, thereby providing a centering mechanism.
  • 80 can be housed within the sheath 16. That is, when the sheath 16 is displaced in the distal direction in a state where the centering mechanism 80 is fixed in the axial direction with respect to the shaft 14 under the action of the fixing mechanism 82 from a state where the centering mechanism 80 is expanded (see FIG. 13A), As shown in FIG. 13B, the second flexible member 40 is moved toward the shaft 14 by the distal end of the sheath 16, and the second slider 36 is accommodated in the sheath 16 to maintain the position in the axial direction with respect to the shaft 14. Is done.

Abstract

La présente invention concerne un dispositif de mise en place d'endoprothèse vasculaire (10A) doté : d'une endoprothèse vasculaire (12) ; d'une tige (14) sur laquelle est placée l'endoprothèse vasculaire (12) ; d'une gaine tubulaire (16) pour recevoir l'endoprothèse vasculaire (12), la gaine tubulaire (16) étant capable de coulisser dans le sens longitudinal relativement à la tige (14) ; et un mécanisme de centrage (20) disposé plus proche de l'extrémité distale que ne l'est l'endoprothèse vasculaire (12) dans la tige (14). Le mécanisme de centrage (20) comprend un corps d'extension (32) qui s'étend lorsque la gaine (16) est déplacée dans la direction de l'extrémité proximale relativement à la tige (14), et centre la tige (14) dans la direction radiale relativement à un vaisseau sanguin par extension du corps d'extension (32).
