Abstract
An integrally woven or knitted textile, such as a tubular graft or sheet, having a base textile layer, in the case of a graft, it has at least one longitudinal tubular graft portion, and at least one pouch or flap integrally woven from at least a portion of the same set of yarns. Methods of making the same are also disclosed.
Core Innovation
The disclosed invention relates to an integrally woven or knitted medical textile that includes a longitudinal textile portion and at least one pouch or flap integrally woven or knitted from at least a portion of a set of yarns and integrally woven or knitted with the longitudinal textile portion. The textile has a first end, a second end, and a length there between, and the pouch is positioned near one end. The pouch includes an outer wall, an inner tubular wall, and an open inner space.
The medical textile provides a slit opening positioned parallel to a longitudinal axis of the textile, where the slit opening is woven or knitted in the outer wall of the pouch and extends across the pouch. In embodiments with multiple pouches, slit openings in different pouches are also woven or knitted in the outer tubular wall of each pouch and extend across each pouch, including an offset relationship between slit openings.
The set of yarns is defined based on whether the textile is integrally woven or integrally knitted, including warp yarns or ends and weft yarns or picks for woven configurations, or wale yarns and course yarns for knitted configurations. The construction emphasizes an integrally formed, seam-free relationship between the pouch and the longitudinal textile portion by interweaving or interknitting the shared yarn set.
Claims Coverage
The provided document content includes two independent claims for an integrally woven or knitted textile. Across the independent claims, the coverage focuses on a longitudinal textile portion integrally formed with one or more pouches, where each pouch has a slit opening woven or knitted in an outer tubular wall and positioned parallel to the textile’s longitudinal axis, with additional structure defined for multiple pouches near respective ends.
Integrally formed longitudinal textile portion with integrally woven or knitted pouch
An integrally woven or knitted textile having a longitudinal textile portion woven or knitted from a set of yarns and at least one pouch or flap woven or knitted from at least a portion of said set of yarns and integrally woven or knitted with the longitudinal textile portion.
Pouch tubular wall structure with open inner space
The at least one pouch has an outer wall, an inner tubular wall and an open inner space, and is positioned near the first end of the textile.
Longitudinally parallel slit opening woven in the pouch outer wall
The first pouch has a slit opening positioned parallel to a longitudinal axis of the textile, wherein the slit opening is woven or knitted in the outer wall of the first pouch and extends across the first pouch.
Second pouch near second end with slit opening in outer tubular wall
A second pouch having an outer wall, an inner wall and an open inner tubular space is provided near the second end of the textile, wherein each pouch has a slit opening positioned parallel to a longitudinal axis of the textile.
Slit openings in multiple pouches woven or knitted in respective outer tubular walls and extending across each pouch
The slit opening in the first pouch and the slit opening in the second pouch are woven or knitted in the outer tubular wall of each of the pouches and extend across each of the pouches.
Together, the independent claims broadly cover an integrally woven or knitted textile where a longitudinal textile portion and at least one pouch are formed from the same yarn set, and where each pouch includes an outer tubular wall with a longitudinally parallel slit opening woven or knitted through that outer wall and extending across the pouch; in the multi-pouch embodiment, pouches near opposite ends each include such a slit opening.
