9. The intraluminal device of claim 1 wherein the plurality of struts and the at least two struts of the mid strut portion are made out of the same piece of material.
10. The intraluminal device of claim 1 wherein the flat plate crush resistance is between approximately 0.1 to 10 Newtons.
11. An intraluminal device comprising:
a first end;
a second end, the first and second ends of the device defining a longitudinal axis; and
a plurality of struts extending from the first end to the second end, wherein the plurality of struts are made from the same piece of material;
wherein at least one of the plurality of struts comprises:
a proximal strut portion adjacent to the first end;
a distal strut portion adjacent to the second end; and
a mid-strut portion between the proximal strut portion and the distal strut portion, the mid-strut portion having at least two struts;
wherein when in an expanded configuration, the plurality of struts are biased away from one another, the at least two struts of the mid-strut portion have an arcuate shape, where the plurality of struts converge towards the longitudinal axis at the second end, and where the device has a flat plate crush resistance that is less than 15 Newtons.
12. The intraluminal device of claim 11 wherein each of the plurality of struts has a rectangular cross section.
13. The intraluminal device of claim 12 wherein each of the plurality of struts has a mid-strut portion having at least two struts.
14. The intraluminal device of claim 11 further comprising a fill material disposed within the device, where the fill material is selected from the group consisting of small intestinal submucosa plugs, nitinol wire, Dacron fibers, and embolization coils.
15. The intraluminal device of claim 14 wherein the width of each of the at least two struts of the mid-strut portion is approximately equal to one half of the width of the proximal strut portion of at least one of the plurality of struts.
16. The intraluminal device of claim 11 wherein the flat plate crush resistance is between approximately 0.1 to 10 Newtons.
17. An intraluminal device comprising:
a first end;
a second end, the first and second ends of the device defining a longitudinal axis; and
a plurality of struts extending from the first end to the second end of the device wherein the plurality of struts are made from the same piece of material;
at least one of the plurality of struts comprising:
a proximal strut portion adjacent to the first end;
a distal strut portion adjacent to the second end; and
a mid-strut portion between the proximal portion and the distal portion, the mid-strut portion having at least two diverging struts made out of the same piece of material as the plurality of struts;
wherein in an expanded configuration the plurality of struts are biased away from one another, the at least two struts of the mid-strut portion have an arcuate shape, where the plurality of struts converge towards the longitudinal axis at the second end, and where the device has a flat plate crush resistance that is less than 15 Newtons.
18. The intraluminal device of claim 17 wherein the flat plate crush resistance is between approximately 0.1 to 10 Newtons.
19. The intraluminal device of claim 18 wherein the length of each of the at least two struts of the mid-strut portion is approximately equal to one half of the overall length of the at least one of the plurality of struts.
