An endoluminal prosthesis comprises a tubular body which can be expanded about a longitudinal axis. A plurality of serpentines extend in a substantially circumferential direction. Each comprises arm portions and bend portions which join two subsequent arms. The bends facing an adjacent serpentine are circumferentially offset relative to the respective opposite bends of the contiguous serpentine, both when the prosthesis is collapsed and when the prosthesis is expanded. A first portion comprises at least two adjacent serpentines interconnected by at least one bridge, and at least two bends situated at the shortest longitudinal distance between the two serpentines is not connected by a bridge. A second portion comprises at least two adjacent serpentines interconnected by a number of bridges equal to the number of pairs of bends of the two serpentines, at the shortest longitudinal distance between the two serpentines. |
