Abstract[English]
The invention provides a compliant stent graft for deployment in the descending aorta to reduce the clinical impact of a stiffened aorta. The compliant stent graft includes a tubular body which extends between a proximal end and a distal end and comprises a proximal anchor section ending at the proximal end and a distal anchor section ending at the distal end. Each section is adapted to move from a constricted state to a dilated state. A treatment section is interposed between the proximal and the distal anchor sections, which is adapted to move from an unexpanded state, having a first volume to an expanded state, having a second volume, wherein, in the unexpanded state, the treatment section has an unexpanded diameter which is less than a constricted diameter of the distal and proximal anchor sections in the constricted state and wherein the difference between the first volume and the second volume is sufficient to retain between 20% and 70 % of the volume of blood ejected during systole.[French]
L'invention concerne une endoprothèse couverte souple destinée à être déployée dans l'aorte descendante pour réduire l'impact clinique d'une aorte rigidifiée. L'endoprothèse couverte souple inclut un corps tubulaire qui s'étend entre une extrémité proximale et une extrémité distale et comprend une section d'ancrage proximale se terminant au niveau de l'extrémité proximale et une section d'ancrage distale se terminant au niveau de l'extrémité distale. Chaque section est conçue pour passer d'un état resserré à un état dilaté. Une section de traitement est interposée entre les sections d'ancrage proximale et distale, et est conçue pour passer d'un état non expansé, ayant un premier volume, à un état expansé, ayant un second volume ; dans l'état non expansé, la section de traitement a un diamètre non expansé qui est inférieur à un diamètre resserré des sections d'ancrage distale et proximale dans l'état resserré ; et la différence entre le premier volume et le second volume est suffisante pour retenir entre 20 % et 70 % du volume de sang éjecté pendant la systole.
