A luminal prosthesis comprises a plurality of radially expandable prosthetic stent segments arranged axially. Two or more of the prosthetic stent segments are separable upon expansion from the remaining prosthetic stent segments and a coupling structure connects at least some of the adjacent prosthetic stent segments to each other. The coupling structure permits a first group of the adjacent prosthetic stent segments to separate from a second group of the prosthetic stent segments upon differential radial expansion of the first group relative to the second group and the coupling structure maintains or forms an attachment between the adjacent prosthetic stent segments in the first group which have been expanded together. A delivery system and methods for deploying the multiple coupled prosthetic stent segments are also disclosed.
Une prothèse luminale comprend une pluralité de segments de prothèse endovasculaire à expansion radiale disposés de façon axiale. Au moins deux de ces segments peuvent se séparer des autres segments lors de la phase d'expansion radiale, une structure de couplage reliant au moins certains des segments adjacents entre eux. Cette structure de couplage permet à un premier groupe de segments adjacents de se séparer d'un second groupe de segments sous l'effet d'une expansion radiale différentielle du premier groupe par rapport au second groupe, la structure de couplage maintenant ou formant un élément de liaison entre les segments adjacents du premier groupe qui ont subi l'expansion ensemble. L'invention concerne également un système et un procédé d'introduction destinés à la mise en place de ces segments de prothèse endovasculaire couplés.
