STENT WITH DUAL SUPPORT STRUCTURE

摘要

A intraluminal stent comprises a reticulated tube having an un-deployed diameter and expandable to an enlarged diameter. The tube includes a structural beam extending between first and second ends. The structural beam changes from a first geometry to a second geometry when the tube changes from the un-deployed diameter to the enlarged diameter. The structural beam includes first and second longitudinal elements each extending at least partially between the first and second ends and with a spacing between the first and second elements. Each of said first and second elements changes from the first geometry to the second geometry when the tube changes from the un-deployed diameter to the enlarged diameter for the spacing to remain substantially unchanged as the tube changes from the un-deployed diameter to the enlarged diameter.

1. An intraluminal stent comprising:
a reticulated tube having an un-deployed diameter and expandable to an enlarged diameter, said tube having a stent axis; said tube including a structural beam extending between first and second ends; said structural beam changing from a first geometry to a second geometry when said tube changes from said un-deployed diameter to said enlarged diameter; said structural beam including first and second longitudinal elements each extending at least partially between said first and second ends and with a spacing between the first and second elements; each of said first and second elements changing from said first geometry to said second geometry when said tube changes from said un-deployed diameter to said enlarged diameter for said spacing to remain substantially unchanged as said tube changes from said un-deployed diameter to said enlarged diameter.
