Abstract
A stent-graft including an inner stent having a wall structure including juxtaposed strut-patterns with interconnected struts and connectors connecting the strut-patterns is described. The wall structure of the inner stent has a predetermined length. An outer stent is coaxially arranged around the inner stent and has a wall structure including juxtaposed strut-patterns with interconnected struts and connectors connecting the strut-patterns. The wall structure of the outer stent has a predetermined length and a flexible stretchable material layer arranged between the inner stent and the outer stent. The wall structure of the inner stent has a design differing from the design of the wall structure of the outer stent and the length of the inner stent is equal to the length of the outer stent.
