Stabilized fabric material for medical devices
11547557 · 2023-01-10 · ·

A stabilized fabric composed of a mesh or a woven fabric is disclosed as are methods of their manufacture, the manufacture of medical devices made using a stabilized fibers and stabilized medical devices are all disclosed. Fabrics can be stabilized by several techniques including: using mechanical, chemical and/or energetic fasteners at warp and weft intersections in the weave; by using various weaving techniques and fibers. Meshes can be stabilized when properly dimensioned and arranged junctions and struts of the necessary properties are used. All of these stabilized fabrics can be made of synthetic polymer materials such as ultrahigh molecular weight PE or PP and expanded PTFE.

Method for weaving three-dimensional preform having gradient structure

A method for weaving a three-dimensional preform includes the following steps: decomposing and determining performance requirements of different functional locations of the parts; selecting guide sleeves and fibers of each of the functional locations and designing a parameter; selecting guide sleeves and fibers of a transition area and designing a parameter, thereby implementing smooth transition of the transition area; determining a weaving sequence according to layouts of the guide sleeves and winding manners of the fibers in the functional locations and the transition area to generate a fiber iterative instruction for layer-by-layer weaving; arranging guide sleeves according to design requirements of the functional locations and the transition area to generate a guide sleeve array; and driving a weaving mechanism to select different fibers for subarea weaving layer by layer to obtain the three-dimensional preform having a gradient structure.

Woven breathable textile

Aspects herein are directed to a woven, breathable textile. The textile comprises a first woven zone and a second woven zone, where the first and second woven zones are integrally woven such that a particular warp yarn extends through both the first woven zone and the second woven zone of the textile. The first woven zone comprises a first woven layer and a second woven layer with a space or void formed between the first and second woven layers. The second woven zone comprises a single woven layer comprising a plurality of apertures formed through the weaving process, where each aperture is located at the center of a repeating pattern of interlacings.

Graft having a pocket for receiving a stent and woven graft material, forming a pocket

A tubular graft for use in a stent graft. The tubular graft may include a first woven layer that forms a first side of the tubular graft, where the first woven layer has a set of first warp ends. A second woven layer may forma a second side of the tubular graft, where the second woven layer has a set of second warp ends, and where the second warp ends are distinct from the first warp ends. A woven pocket flap may extend from the first woven layer, where a pocket opening is defined between the woven pocket flap and the first woven layer, and where the woven pocket flap includes at least one common weft yarn with the first woven layer.

Ultra-thin fabric, devices, and methods

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.sup.2; and a thickness of less than about 3.2 mil. The fabric can further comprises a weight of less than about 60 g/m.sup.2. 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.

Zoned fabric systems and methods

A garment may include a first woven component, a second woven component, a space between the first and second woven components defining a channel filled with a fill material, and a third woven component extending such that the first and second woven components are woven together where there is no channel. The channel may be filled with a filler material. Multiple channels may be provided such that they form a zoned pattern in the garment.
