Abstract
Continuously flat-woven implantable tubular prostheses have seamless woven sections which gradually change the number of warp yarns to smoothly transition, i.e., taper, from one diameter to another. Multi-diameter endoluminal grafts having a variety of shapes and configurations are made using a seamless weaving process without unacceptable voids or gaps in the tubular wall.
Claims13
A flat-woven implantable tubular prosthesis comprising:
- a first substantially fluid-tight tubular woven section having a plurality of warp yarns and fill yarns,
- a second substantially fluid-tight tubular woven section having a plurality of warp yarns and fill yarns,
- a third substantially fluid-tight tubular woven section having a plurality of warp yarns and fill yarns and
- a substantially fluid-tight woven crotch section having warp yarns from said first woven section gradually interwoven with warp yarns from each of said second and third woven sections to seamlessly contiguously join said first woven section to said second and third woven sections at said crotch section.

A method of making a flat-woven implantable tubular prosthesis comprising:
- weaving a first substantially fluid-tight tubular woven section by using a plurality of warp yarns and fill yarns,
- weaving a second substantially fluid-tight tubular woven section by using a plurality of warp yarns and fill yarns,
- weaving a third substantially fluid-tight tubular woven section by using a plurality of warp yarns and fill yarns and
- weaving a substantially fluid-tight woven crotch section by gradually interweaving warp yarns from said first woven section with warp yarns from each of said second and third woven sections to seamlessly contiguously join said first woven section to said second and third woven sections at said crotch section.
