A side branch stent graft (1) suitable for the iliac arteries has a main tubular body (3) of a biocompatible graft material and a tubular side branch (5). The tubular side branch is affixed into the main tubular body so that a side branch lumen is in fluid communication with a main lumen. There is at least one external zig-zag stent (13) on the main tubular body proximal of the tubular side branch, one central external stent (14) which also encompasses the side arm, at least one external zig-zag stent (16) on the main tubular body distal of the tubular side branch and one internal zig-zag stent (15) at the distal end of the main tubular body. A reinforcing ring (9) is around the proximal end of the main tubular body and stitched thereto.

L'invention concerne une endoprothèse (1) couverte à ramification latérale, convenant pour les artères iliaques, comprenant un corps tubulaire (3) principal formé d'un matériau de greffon biocompatible, et une ramification (5) latérale. La ramification latérale est fixée dans le corps tubulaire principal de telle manière que la lumière de la ramification latérale communique fluidiquement avec la lumière principale. Cette endoprothèse comprend au moins un tuteur (13) externe en zigzag sur le corps tubulaire principal du côté proximal de la ramification latérale tubulaire, un tuteur (14) externe central qui entoure également le bras latéral, et au moins un tuteur (16) externe en zigzag à l'extrémité distale du corps tubulaire principal. Un anneau (9) de renfort entoure l'extrémité proximale du corps tubulaire principal et est suturé sur ce dernier.
