The present invention relates to a self-expanding endoprosthesis intended to support walls of anatomical channels. The endoprosthesis according to the invention comprises 2n external longitudinal elements, and 2n other intermediate longitudinal elements, distributed in a parallel arrangement about the axis of the endoprosthesis, and offset with respect to one another along the axis, and a plurality of rings distributed about the axis of the endoprosthesis, joining the longitudinal elements and each being in the form of a filament of zigzag configuration. According to the invention, the folded-down configuration of the endoprosthesis is obtained by longitudinal traction of the external elements with respect to the intermediate elements. |
