First Claim
1. A vascular repair device, comprising:
- a tubular graft body having an upstream end, a downstream end, and an interior surface;
a clasping stent partially attached to said interior surface of said graft body which covers said clasping stent, said clasping stent having a circumference defining upstream apices, downstream apices, and struts that define respective adjacent ones of said upstream and downstream apices, each of said struts having an upstream portion and a downstream portion, said upstream portion of at least some of said struts being unattached from said interior surface of said graft body, and said upstream apices defined by said unattached struts and being unattached from said interior surface of said graft body, whereby at least one continuous length of the clasping stent, the continuous length including adjacent unattached upstream portions of the struts and the upstream apex they define, is unattached from the tubular graft body; and
a crown stent between the clasping stent and the upstream end of the tubular graft body and fixed along the entire length of the crown stent to the tubular graft body, the crown stent being adjacent to the clasping stent and the crown stent including upstream and downstream apices, wherein the upstream apices of the clasping stent are nested between downstream apices of the crown stent and attached portions of the clasping stent extend upstream of portions of downstream apices of the crown stent that are fixed to the tubular graft body, and wherein the at least one unattached continuous length of the clasping stent is upstream of the downstream apices of the crown stent, whereby radial collapse of the at least one unattached continuous length of the clasping stent causes at least partial radial collapse of the crown stent and the graft body.

Abstract
A vascular repair device includes a tubular graft body having upstream and downstream ends, and an interior surface and a clasping stent partially attached to the interior surface. The clasping stent circumference defines upstream and downstream apices, and struts connecting respective adjacent apices. The struts each have upstream and downstream portions. The upstream portion of some of the struts is unattached from the interior surface and some of the upstream apices adjacent the unattached struts are also unattached. A crown stent can be attached circumferentially to the graft body adjacent the upstream end as a part of the support framework. The downstream apices and the downstream portion of the struts can be attached to the interior surface of the graft body with only some of the upstream halves and the upstream apices attached to the interior surface of the graft body.
