Implantable graft device having treated yarn and method for making same

1. An implantable graft device having treated yarn, the device comprising:

a graft body forming a lumen defining a longitudinal axis and comprising proximal and distal ends, the graft body comprising a woven fabric having warp yarns aligned in a first direction and weft yarns aligned in a second direction, the warp and weft yarns being formed from a material selected from the group consisting of a polyester, a fluorinated polymer, a polyurethane, a polyethylene, a polypropylene, a polyaramid, a polyacrylonitrile, a nylon, a cellulose, and combinations thereof, at least one of the weft yarns and the warp yarns defining the treated yarn, the treated yarn comprising a first strand and a second strand, the first strand and the second strand being twisted together to form the treated yarn, only the first strand having a first agent applied thereto.

2. The device of claim 1 wherein the first agent is one of an anti-microbial agent, antibiotic agent, and an antithrombogenic agent.

3. The device of claim 1 further comprising:

an expandable stent disposed circumferentially on the graft body and about the longitudinal axis; and

an anchor portion extending from the proximal end of the graft body, the anchor portion having a first woven portion and a barb stent attached thereto for reduced migration of the graft device, the first woven portion being comprised of woven yarn; and

an end portion extending from the distal end of the graft body, the end portion having a second woven portion and an end stent attached thereto, the second woven portion being comprised of woven yarn.

4. The device of claim 3 wherein the first woven portion comprises an inner side, the barb stent being attached to the inner side of the first woven portion.

5. The device of claim 4 wherein the barb stent comprises a plurality of loops attached to the first woven portion.
