An endoluminal prosthesis (500) comprises a tubular body (502) suitable to turn from a collapsed to an expanded or partially expanded condition which develops along a longitudinal axis (504). A plurality of serpentines (506a-d, 508a-e, 510a-d), or closed meander paths develop in a substantially circumferential direction Each serpentine comprises arm portions, or arms (511), and bend portions or bends (512), which join two subsequent arms (511). The bends facing an adjacent serpentine are circumferentially offset relative to the respective and opposite bends (512) of the contiguous serpentine, both when the prosthesis is collapsed and when the prosthesis is expanded or partially expanded. A first portion (506, 510) comprises at least two adjacent serpentines interconnected by at least one bridge (514a), and at least a pair of bends situated at the shortest longitudinal distance between the two serpentines is not 0 connected by a bridge. A second portion (508) comprises at least two adjacent serpentines interconnected by a number of bridges (514b) equal to the number of pairs of bends of the two serpentines being at the shortest longitudinal distance between the two ser entines. |
