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.

Claims (5)

THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE
PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A flat-woven tubular implantable prosthesis having warp yarns and fill yarns comprising first and second ends defining a tubular wall therebetween, said tubular wall having a first woven extent with a first selected number of warp yarns therealong to define a first tubular internal diameter, a transitional second woven extent contiguous with said first woven extent with at least a second selected number of warp yarns therealong to define at least a second tubular internal diameter which is different from said first tubular internal diameter, and at least a third woven extent contiguous with said second woven extent with a third selected number of warp yarns which is different from said first and said second selected number of warp yams, said at least third woven extent defining a third tubular internal diameter which is different from said first and second tubular internal diameters.
2. The prosthesis of claim 1 wherein said transition from said first tubular internal diameter to said third tubular internal diameter is seamless and gradual.
3. The prosthesis of claim 2 wherein said gradual transition is defined by a change of no more than 3 of said warp yarns for every 2 of said tubular fill yarns.
4. The prosthesis of claim 3 wherein said third woven extent further comprises at least two tubular members forming a bifurcated arch.
5. The prosthesis of claim 4 wherein said bifurcated arch includes warp yarns from said transitional second woven extent gradually interwoven with warp yarns from each of said two tubular members.
