Ultra-thin fabric, devices, and methods |
摘要 |
A 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 cm; and a thickness of less than about 3.2 mil. The fabric can further comprises 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. |

1. A fabric, comprising:
yarns, comprising more than 1 and less than about 30 denier total and more than 0.1 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; wherein the fabric further comprises a water permeability rating of less than about 400 cc/min/cm2 at 120 mm Hg pressure. |
