摘要：
Described here are devices and methods for closing one or more vascular openings. The devices may include a stent graft comprising a stent framework and a graft material at least partially covering the stent framework. The stent framework may comprise one or more axial segments, and at least one of the axial segments may comprise an access port through which a catheter or treatment device may enter the stent graft. The methods may comprise occluding blood flow upstream of a vascular opening, and delivering a closure device to block, cover, or seal the vascular opening.
