Systems and methods for manufacturing a woven seamed structure are provided herein. A method includes providing a plurality of threads parallel to a warp axis and providing a weaving thread, and then weaving the weaving thread into the plurality of threads back and forth in directions parallel to a weft axis. The weaving thread, in a machine direction, changes patterns at positions along the weft axis that change gradually or intermittently as the weaving thread is woven in the machine direction such that a first transition line and a second transition line, respectively, are formed at non-zero angles from the warp axis and the weft axis. This forms a woven seamed structure with a central axis that extends along a non-zero angle from the warp axis or the weft axis, such example woven seamed structure exhibiting enhanced stretchability and conformance.

Fabric can comprise yarns comprising less than about 30 denier total and less than about 10 denier per filament; a density of greater than about 177 yarns per cm2; and a thickness of less than about 3.2 mil. The fabric can further comprise a weight of less than about 60 g/m2. The fabric can have performance characteristics equivalent to or greater than those in conventional implantable fabrics. A method of making such a fabric can include twisting together filaments into a multifilament yarn; passing adjacent yarns into a loom in parallel so as to allow the yarns to be woven together more closely; maintaining a consistent tension on the yarns during placement of the yarns on a loom beam and during weaving; and or subjecting the fabric to increased heat and pressure so as to compress the yarns more tightly.

An elongation resistant fabric, devices, and methods can include an elongation resistant yarn laid in a knit structure of the fabric between knit loops in selected adjacent wales and partially about the loop in one adjacent wale in predetermined courses. In this manner, the fabric can be adapted to resist elongation in a walewise direction along the length of the fabric. The elongation resistant fabric can be a mesh fabric. In a mesh fabric, the size and a shape of pores in the fabric can be maintained when the fabric is pulled in the walewise direction. The elongation resistant yarn can have a diameter larger than the individual diameters of other yarns in the fabric. The elongation resistant yarn can be, for example, a monofilament yarn, such as a polypropylene or polyester monofilament yarn.

A compressible resilient fabric can include a ground layer of knitted yarn, and a loop layer comprising a plurality of loops of yarn, each loop having a point knit into the ground layer. The fabric can be compressible from an non-compressed configuration, in which each loop has an apex extending substantially perpendicularly outward from the ground layer, into a compressed configuration, in which each loop is collapsed onto the ground layer. The fabric can further be resilient so as to substantially resume the non-compressed configuration when compression is relieved. The loop layer yarn can include a multifilament yarn having a high denier per filament ratio. The ground layer yarn can include a yarn shrinkable substantially more than the loop layer yarn. The loops can be densely knit so as to support the extension of the loops outward from the ground layer.

A fabric medical device and method of making the device can include warp yarns and fill yarns woven together to form a first tubular extent having a first diameter, a second tubular extent having a second diameter, and a transition tubular extent having a graduated diameter between the first and second tubular extents. A tapered edge can be formed along the transition tubular extent by weaving such that a graduated number of warp yarns are disengaged along the transition tubular extent. A seam can be woven along the tapered edge that is configured to provide a substantially fluid-tight transition between the first and second tubular extents. The device can further include the warp yarns in at least the transition tubular extent having a tenacity higher than the tenacity of the fill yarns. The device can be a bone filler delivery device adapted to deliver bone filler in an internal body region.
