SECTIONAL CRIMPED GRAFT |
摘要 |
The present invention provides a sectional crimped graft that allows graft flexibility where required and limits the overall longitudinal extension. Th e present invention overcomes the disadvantage of fully crimped grafts by controlling the number of crimps per unit length, crimp height, crimp geomet ry and their location along the graft wall, dependent on the particular end-use application. In so doing, flexibility and elongation can be controllably tailored only in areas where significant anatomical angulation is present. I t may also be useful in applications other than stent grafts such as surgical grafts for aortic and peripheral areas. Limiting the overall graft longitudinal extension also facilitates the deployment of the stent-graft in to the blood vessel. |
