Abstract:
1. Endoluminal prosthesis, comprising a tubular body suitable to turn from a collapsed state to an expanded or partially expanded state, said body extending along a longitudinal axis, said tubular body comprising a plurality of serpentines, or closed meander paths, extending along a substantially circumferential direction relative to said longitudinal axis, each of said serpentines comprising arm portions, or arms, of a preset width transverse to the main longitudinal extension thereof, each of said serpentines comprising bend portions, or bends, joining two subsequent arms to form said meander path, at least one bridge having a main longitudinal extension, connecting two adjacent serpentines, thus forming at least two cells between said two adjacent serpentines, wherein the bends facing an adjacent serpentine are circumferentially staggered relative to the opposite bends of the contiguous serpentine, both when the prosthesis is collapsed and when the prosthesis is expanded or partially expanded, wherein the at least one bridge connecting adjacent serpentines extends substantially straight, and wherein the at least one bridge has a width transverse to its main longitudinal extension of a greater value than the arm width, wherein at least one serpentine comprises at least one frame defining a slot located at the bend between two arms in place of at least two arms and one bend compared to a second serpentine, a radiopaque material being provided within said slot.
