Claim 20:
21. A method of making an integrally woven tubular graft having a first end, a second end and a length thereinbetween, comprising a first, second, third longitudinal tubular graft portion comprising:
weaving the first longitudinal tubular graft portion using a set of yarns such that the first longitudinal tubular graft portion comprises an inner surface and an outer surface;
weaving a first pouch integrally with a portion of the first longitudinal tubular graft portion from at least a portion of said set of yarns such that (i) the first pouch comprises an inner surface and an outer surface, and (ii) the inner surface of the first pouch faces the outer surface of the first longitudinal tubular graft portion so as to define a first opening that leads to an open inner space between the inner surface of the first pouch and the outer surface of the first longitudinal tubular graft portion;
weaving the second longitudinal tubular graft portion integrally with the first longitudinal tubular graft portion and the first pouch from said set of yarns such that the second longitudinal tubular graft portion comprises an inner surface and an outer surface;
weaving a second pouch integrally with a portion of the first longitudinal tubular graft portion, the first pouch and the second longitudinal tubular graft portion from at least a second portion of said set of yarns such that (i) the second pouch comprises an inner surface and an outer surface, and (ii) the inner surface of the second pouch faces the outer surface of the second longitudinal tubular graft portion so as to define a second opening that leads to an open inner space between the inner surface of the second pouch and the outer surface of the second longitudinal tubular graft portion; and
weaving the third longitudinal tubular graft portion integrally with the first longitudinal tubular graft portion, the first pouch, the second longitudinal tubular graft portion, and the second pouch from said set of yarns such that the third longitudinal tubular graft portion comprises an inner surface and an outer surface;
wherein the set of yarns comprises at least one set of warp yarns or ends and at least one set of weft yarns or picks;
wherein the first longitudinal tubular graft portion, the first pouch, the second longitudinal tubular graft portion, the second pouch, and the third longitudinal tubular graft portion share at least a portion of the same set of yarns; and
wherein the first longitudinal tubular graft portion, the second longitudinal tubular graft portion, and the third longitudinal tubular graft portion form a continuous tube from the first end to the second end of the tubular graft.
