Lumen repair device with capture structure
First Claim
1. A vascular repair device, comprising:
- a tubular graft body having an upstream end, a downstream end, and an interior surface; and
a clasping stent partially attached to said interior surface of said graft body and covering said clasping stent, said clasping stent having a circumference defining upstream apices, downstream apices, and struts connecting 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 some of said upstream apices adjacent said unattached struts being unattached from said interior surface of said 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.
