Abstract
A tubular graft for use in a stent graft. The tubular graft may include a first woven layer that forms a first side of the tubular graft, where the first woven layer has a set of first warp ends. A second woven layer may forma a second side of the tubular graft, where the second woven layer has a set of second warp ends, and where the second warp ends are distinct from the first warp ends. A woven pocket flap may extend from the first woven layer, where a pocket opening is defined between the woven pocket flap and the first woven layer, and where the woven pocket flap includes at least one common weft yarn with the first woven layer.
Claims14
A tubular graft for use in a stent graft, the tubular graft comprising:
- a first woven layer that forms a first side of the tubular graft, the first woven layer having a set of first warp ends;
- a second woven layer that forms a second side of the tubular graft, the second woven layer having a set of second warp ends, wherein the second warp ends are distinct from the first warp ends;
- and
- a woven pocket flap that extends from the first woven layer, wherein a pocket opening is defined between the woven pocket flap and the first woven layer, and wherein the woven pocket flap includes at least one common weft yarn with the first woven layer,
- wherein the woven pocket flap includes a mouth configured to provide access to the pocket opening, the mouth facing a proximal direction or a distal direction such that the woven pocket flap is configured to receive an apex of a stent through the mouth;
- and
- the woven pocket flap further comprising a first woven pocket flap and a second woven pocket flap, the mouth further comprising a first mouth facing the proximal direction and a second mouth formed by the second woven pocket flap facing the distal direction for receiving a second apex of the stent.
A tubular graft for use in a stent graft, the tubular graft comprising:
- a first woven layer that forms a first side of the tubular graft, the first woven layer having a set of first warp ends;
- a second woven layer that forms a second side of the tubular graft, the second woven layer having a set of second warp ends, wherein the second warp ends are distinct from the first warp ends;
- and
- a woven pocket flap that extends from the first woven layer, wherein a pocket opening is defined between the woven pocket flap and the first woven layer, and wherein the woven pocket flap includes at least one common weft yarn with the first woven layer,
- wherein the woven pocket flap includes a mouth configured to provide access to the pocket opening, the mouth facing a proximal direction or a distal direction such that the woven pocket flap is configured to receive an apex of a stent through the mouth,
- wherein the woven pocket flap includes a set of third warp ends, and wherein within a pocket area, the third warp ends are distinct from the first warp ends and the second warp ends.
A tubular graft for use in a stent graft, the tubular graft comprising:
- a first woven layer that forms a first side of the tubular graft, the first woven layer having a set of first warp ends;
- a second woven layer that forms a second side of the tubular graft, the second woven layer having a set of second warp ends, wherein the second warp ends are distinct from the first warp ends;
- and
- a woven pocket flap that extends from the first woven layer, wherein a pocket opening is defined between the woven pocket flap and the first woven layer, and wherein the woven pocket flap includes at least one common weft yarn with the first woven layer,
- wherein a triangular portion of the woven pocket flap forms an exterior surface of the tubular graft,
- wherein the woven pocket flap includes a mouth configured to provide access to the pocket opening, the mouth facing a proximal direction or a distal direction, and
- wherein the woven pocket flap includes a set of third warp ends, and wherein within a pocket area, the third warp ends are distinct from the first warp ends and the second warp ends.
