Abstract

A vascular endoprosthesis (100, 200, 300, 400, 500, 600) includes a radially-expandable first segment and a radially expandable second segment. The vascular endoprosthesis further includes first and second coupling elements. The first coupling element extends from the proximal end of the first segment toward the distal end of the second segment, and the second coupling element extends from the distal end of the second segment toward the proximal end of the first segment. The first and second coupling elements cooperate one with another to couple the first and second segments together when the vascular endoprosthesis is in a delivery configuration and to decouple the first and second segments when the vascular endoprosthesis is in a deployed configuration.
