Abstract

Stent exhibiting a succession of turns around the axis, adjacent turns being connected by connector portions distributed around the circumference of the prosthesis, each of the turns being made up of struts that extend the length of the turn and are interspersed by inflection zones located at the axial ends of each of the turns. When the prosthesis expands radially, gaps open up between adjacent struts of each of the turns, the inflection zones being distributed regularly around the circumference so that the gaps are substantially the same size as each other around the circumference of the turn, characterized in that at least every second turn exhibits a stagger zone within which the said gap between adjacent said struts is of an individual size different from that common to the other gaps of that second turn.
