  • Patent number: 11504222
    Abstract: A branched graft method includes securing a first end of a branch graft into a first conduit and subsequently moving the second end into a second conduit. The first conduit may be a branch vessel, such as a renal artery and the second conduit may be a main graft that extends over an aortic aneurysm. The branch graft may be deployed starting at an offset distance from the first end, thereby preventing the deployed portion from insertion into the first conduit and predetermining the insertion length into the target vessel. The first end may then be deployed to secure the first end to the first conduit. A branch graft may be a self-expanding stent graft having one or more ripcords, and/or a serpentine ripcord that enables non-linear deployment of the branch graft, or deployment that does not progress from one end to the opposing end.

  • Publication number: 20140260437
    Abstract: A skin-contacting fabric underlay for use beneath a therapeutic or prosthetic device on a human or animal body part is formed as a tube of knitted fabric. The yarns forming the fabric have a core of elastic material surrounded by moisture-transporting filaments of substantially non-elastic material, the yarn having elasticity, the fabric having a warp-knitted structure characterized by an artificial terry surface on an inner skin-contacting surface of the tube. The artificial terry surface is formed by underlaps of the yarn, in which the elasticity of the yarn causes the underlaps to draw up and form artificial terry loops that contact the skin of the body part about which the tube is sleeved. The artificial terry loops serve to space overlaps of the yarn from the skin and to move moisture away from the skin.

  • Patent number: 7739888
    Abstract: The invention relates to a method and related equipment for manufacturing shaped fabrics or anatomically shaped tubular hosiery and knitwear items, obtained with Raschel looms having preferably two parallel needle beds and automatic latch needles. During the knitting process, by gradually varying the height of the needle bed and of the sinking plane lying above with respect to the needles sliding in the same bed, knitting density can also be suitably changed. As a consequence, concerned anatomic parts such as the bodice and ankles of a pair of tights or a stockings as well as the waist and sleeves of a sweater can be shaped with higher accuracy and effectiveness.

  • Patent number: 7285505
    Abstract: The present disclosure relates to a tape that comprises a weft-inserted warp knit fabric, which utilizes a combination stitch to secure the wales of the fabric. The combination stitch comprises a majority of successive chain stitches that are used with a minority of subsequent successive tricot stitches, such that the stitch follows the expression x+y, where x is the number of successive chain stitches and y is the number of subsequent successive tricot stitches. Contemplated x values are in the range of 5 to 15, and contemplated y values are in the range of 1 to 4. Multiple stitch formations can also be used (e.g., following an x+y/m+n/etc. configuration). The resulting weft-inserted warp knit fabric possesses superior dimensional stability and internal geometry, while maintaining the tearability requisite for a hand-tearable tape product.

  • Patent number: 7269978
    Abstract: The invention relates to a mesh for bags or packaging, produced by knitting technology by warping in a circular loom of simultaneous mesh formation. The mesh constitutes a uniform tubular mesh structure wherein the warp yarns or bands form mesh chains parallel to the longitudinal axis of the tubular mesh and the weft yarns or bands perpendicular to said axis are interwoven between at least two adjacent mesh chains so that each weft yarn or band traverses the meshes of said chains, constituting a uniform tubular mesh without longitudinal seams or perpendicular mesh bonds.

  • Patent number: 6092395
    Abstract: In a high speed circular warp thread knitting machine latch needles are reciprocated in respective, vertical tricks in a stationary cylinder by a cam rotating around the cylinder thereby to engage warp threads drawn down from above. A presser plate rotating with the cam deflects each warp thread in turn across a needle while the latch of the latter is open. According to the invention each warp thread descends uninterruptedly to a respective needle trick from an eyeleted disc at an acute angle to the vertical and the presser plate has a leading surface which extends forwardly and toward the cylinder at an acute angle to a radius of the cylinder. In a preferred embodiment a wire latch guard extends forwardly from and moves with the presser plate so that its free end is positioned to obstruct closing movement of the latch of a rising needle just as the latch is released by casting off the previously formed loop of thread onto the shank of the needle.

  • Patent number: 6035668
    Abstract: A shaped (multi-sided), circular warp-knit cord construction is provided with localized distributions of yarns on selected sides of the cord by selectively positioning and rotating yarns on a yarn guide. The yarns are positioned and rotated in such a manner that yarns of the same type of material are repeatedly located in the same knitting position or a closely spaced or adjacent position for each knitted course. Shaping of the cord is provided by selectively locating interlace yarns around the circumference of the cord construction. For example, four equally circumferentially spaced interlace yarns will form a square knit configuration having four distinct sides when viewed in cross-section. By selectively grouping and rotating yarns of the same type of material, yarns can be localized on a selected side or side of the cord construction.

  • Patent number: 4977759
    Abstract: Improved drive means is provided for imparting clockwise and counterclockwise reciprocal movements to the yarn guides of a circular warp knitting machine including a plurality of vertically reciprocated needles. The improved drive means includes an endless timing belt drivingly connected to the yarn guides and a crank arm drivingly connected at one end to the endless timing belt. A rotary drive wheel is connected to the opposite end of the crank arm for imparting continuous longitudinal reciprocation to the crank arm and to thereby impart reciprocating movement to the endless timing belt and the yarn guide drivingly connected thereto. The yarn guide may include a first yarn guide for directing a base or ground yarn to the needles and a second yarn guide for directing an inlay yarn to the needles. Endless timing belts are utilized in driving each of the base yarn guide and the inlay yarn guide and the timing belt drive permits the circular warp knitting machine to be operated at an increased operating speed.
