Abstract
An implantable graft device is disclosed. The device comprises a graft body forming a lumen defining a longitudinal axis and comprising proximal and distal ends. The graft body comprises a woven fabric having warp yarns aligned in a first direction and weft yarns aligned in a second direction. The weft yarns are woven with the warp yarns. A portion of the warp yarns along the longitudinal axis of the graft body are not interwoven with the weft yarns, defining floating yarns having loops aligned in one of the first direction and the second direction. The device further comprises an expandable stent disposed circumferentially about the longitudinal axis and received through the loops of the floating yarns to attach the stent to the graft body.
