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.
Claims9
A flat-woven tubular prosthesis comprising a varying diameter, single tubular wall portion having a first longitudinal expanse portion comprising a number of first warp yarns of a first polymer defining a tubular shape of a first diameter and transitioning therefrom a second longitudinal expanse portion comprising a number of second warp yarns of a second polymer defining a tubular shape of having a second diameter, wherein said first diameter is different from said second diameter.
