Abstract:
An implantable textile prosthesis comprising:a first woven section comprising an elongate tubular main wall defining a fluid passageway therethrough; and a second woven section comprising a tubular branch wall defining a fluid passageway therethrough, said tubular branch wall including an elongate tubular extent and an asymptotically flared tubular extent, asymptotic with respect to said tubular branch wall, having a first and a second end, said second end of said asymptotically flared tubular extent being contiguous with said elongate tubular extent, said asymptotically flared tubular extent including a weaving pattern having a plurality of warp yarns and fill yarns and incorporating a gradual change in the number of warp yarns with respect to said fill yarns to provide a seamless and substantially fluid-tight transition region along said flared tubular extent; said first end of said asymptotically flared tubular extent being secured to said first woven section to provide said tubular branch wall extending laterally in a substantially perpendicular fashion from said tubular main wall, to establish fluid communication between said tubular main wall and said tubular branch wall and to provide a substantially non-turbulent fluid path therethrough.
