A fiber texture presents the shape of a strip extending in a longitudinal direction over a determined length between a proximal portion and a distal portion, and in a lateral direction over a determined width between first and second lateral edges. The fiber texture presents three-dimensional or multilayer weaving. The proximal portion of the fiber texture includes an end portion extending in the lateral direction so as to be set back from at least one of the first and second lateral edges and over a determined width that is less than the width of the fiber texture. The end portion projects in the longitudinal direction from at least one longitudinal edge of the fiber texture, the end portion extending in the longitudinal direction between a first end connected to the fiber texture and a free, second end opposite from the first end.

Provided is a high-density medical fabric that can be suitably used as a graft for a branched stent graft, can accommodate diameter changes, has the burst strength required of a material to be implanted in a body, and has a seamless tubular shape that can narrow in diameter.

Aspects herein are directed to using a space-treating process to apply functional finishes to a yarn and incorporating the treated yarn into a textile and/or a garment to impart engineered functional properties to the textile and/or garment.

A woven prosthesis, such as a woven vascular graft, woven from warp and weft yarns. Velour warp yarns forming the prosthesis are selectively incorporated into a base layer of the prosthesis so as to provide a bulbous section without compromising the porosity of the prosthesis.

The present disclosure provides a method for manufacturing a preform made of reinforcement fibers woven in a longitudinal direction. The preform is impregnated with resin in order to form an elongated element having a variable transverse cross-section. In one form, the method includes the step of simultaneously including a reduction (or increase) in width and an increase (or reduction) in height. The variable cross-section includes, along the length thereof, a consistent number (c) of continuous warp threads arranged in layers. The method for reducing width includes carrying out a change in weave, adding additional weft threads, and simultaneously drawing the teeth of the longitudinal beater reed closer together so as to increase the number of layers.
