Abstract:
1. A vascular endoprosthesis comprising: a radially expandable first segment having a proximal end and a distal end; a radially expandable second segment having a proximal end and a distal end; a first spiral coupling element extending from said proximal end of said first segment toward said distal end of said second segment; and a second spiral coupling element extending from said distal end of said second segment toward said proximal end of said first segment, wherein said first spiral coupling element and said second spiral coupling element couple said first segment and said second segment when in a delivery configuration, and wherein said first spiral coupling element and said second spiral coupling element decouple when said first segment and said second segment are in a deployed configuration, wherein the first segment is deployed before the second segment and wherein the first spiral coupling element and the second spiral coupling element remain coupled during deployment of the first segment, wherein said first spiral coupling element uncoils and disconnects to release from said second spiral coupling element by a distance in a longitudinal direction of the vascular endoprosthesis.
