Abstract
A medical prosthesis implantable in an anatomical duct in order to treat a disease of the 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 along a series of parallel helices coiled around the longitudinal axis, the meanders having apices alternately directed towards the proximal end and the distal end, and second structural discrete elements extending along a series of parallel lines perpendicular to the longitudinal axis, the second structural discrete elements being individually arranged between two adjacent first structural elements and defining connecting struts by intersecting the two adjacent first structural elements, the second structural discrete elements showing changes of slope with at least one shoulder, but not apices.
