STENT GRAFT
First Claim
1. A stent-graft comprising:
- an inner stent having a wall structure including juxtaposed strut-patterns with interconnected struts and connectors connecting the strut-patterns, the wall structure of the inner stent having a predetermined length;
an outer stent coaxially arranged around the inner stent and having a wall structure including juxtaposed strut-patterns with interconnected struts and connectors connecting the strut-patterns, the wall structure of the outer stent having 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 having a design differing from the design of the wall structure of the outer stent, and the length of the inner stent being equal to the length of the outer stent.

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.
