Abstract:
A one-piece medical prosthesis implantable in an anatomical duct, in order to treat a disease of said duct, the prosthesis having:a longitudinal axis, a first radially restricted state or a second radially expanded state, a proximal end and a distal end, first structural elements having meanders extending essentially perpendicular to the longitudinal axis, the first structural elements having first, high apices alternately directed towards the proximal end and the distal end, some of two successive of said first, high apices being separated by second, less high apices, two successive apices being connected together by connecting intermediate lengths so that said first structural elements define a series of meandering cylinders staggered along the longitudinal axis, second and third connecting structural discrete elements connecting two adjacent staggered meandering cylinders together, the second connecting structural discrete elements intersecting said adjacent staggered meandering cylinders at two adjacent, high apices thereof, respectively directed towards the proximal end and the distal end of the prosthesis, and, the third connecting structural discrete elements intersect two adjacent staggered meandering cylinders at connecting intermediate lengths thereof.
