The low profile vascular graft (10) of the present invention includes a tube structure (12) having outer and inner surfaces (14, 16), and a support structure (38) having a chamber structure (40) secured to the outer or inner surface. The support structure includes a core structure (62) contained within the chamber structure. The core structure is transformable from a conformance condition to a reinforcement condition. When the core structure is in the conformance condition, it provides insubstantial resistance to deformation of the tube structure. When the core structure is in the reinforcement condition, it provides substantial resistance to deformation of the tube structure.
L~invention concerne un greffon vasculaire ultra-mince (10) comportant une structure de tube (12) présentant des surfaces extérieure et intérieure (14, 16), et une structure support (38) présentant une structure de chambre (40) fixée sur la surface extérieure ou intérieure. La structure support comporte une structure de noyau (62) reçue dans la structure de chambre. La structure de noyau est capable de passer d~un état de conformité à un état de renforcement. Lorsque la structure de noyau occupe l~état de conformité, elle offre une résistance négligeable à la déformation de la structure de tube. Lorsque la structure de noyau occupe l~état de renforcement, elle offre une résistance importante à la déformation de la structure de tube.
