Title (EN) ENDOLUMINAL GRAFT WITH INTEGRAL STRUCTURAL SUPPORT AND METHOD FOR MAKING SAME
(FR) IMPLANT ENDOLUMINAL COMPORTANT UN SUPPORT STRUCTUREL INTEGRAL, ET PROCEDE DE FABRICATION
Abstract: front page image
(EN)A structurally supported graft (10) having a support structure (26) with strain relief sections (30) contained with an internal surface, an external surface, or a wall thickness of a tubular graft member (12). The structurally supported graft (10) may include a beading element (24) which is coextruded with the support structure (26) having strain relief sections (30) and spiraled about the tubular graft (10). The support structure (26) includes differing types of strain relief sections (30) which are capable of allowing for the longitudinal and radial expansion of the structurally supported graft, respectively. The strain relief sections may also include unconnected ends which form outwardly protruding barbs (62) upon expansion of the structurally supported graft for anchoring the graft within a blood vessel or body lumen. The method for making the structurally supported graft includes selecting or preparing a support structure with strain relief sections, co-extruding the structural support with a beading element, forming a spiral about the tubular graft with the co-extruded structure, and securing the co-extruded structure to the tubular graft.
(FR)La présente invention concerne un implant (10) possédant une structure de support (26) qui comporte des sections de relâchement de la tension (30) se trouvant sur la surface interne, sur la surface externe, ou encore dans l'épaisseur de la paroi d'un élément de l'implant tubulaire (12). Cet implant (10) à structure de support peut comporter un élément de bordage (24) qui est co-extrudé en même temps que la structure de support (26) comportant des sections de relâchement de la tension (30), et qui est enroulé en spirales autour de l'implant tubulaire (10). La structure de support (26) comprend différents types de sections de relâchement de la tension (30) qui permettent l'expansion longitudinale et radiale, respectivement, de l'implant à structure de support. Les sections de relâchement de la tension peuvent également comprendre des extrémités libres formant des barbes (62) qui dépassent vers l'extérieur lors de l'expansion de l'implant à structure de support, et permettent d'ancrer l'implant dans un vaisseau sanguin ou une lumière du corps. Le procédé de fabrication de cet implant à structure de support consiste à choisir ou préparer une structure de support comportant des sections de relâchement de la tension, à co-extruder le support structurel en même temps qu'un élément de bordage, à former une spirale autour de l'implant tubulaire à l'aide de la structure co-extrudée, puis à fixer ladite structure co-extrudée à l'implant tubulaire.
