  • Patent number: 10907283
    Abstract: Methods of braiding using a braiding mechanism are described. The braiding machine includes first and second annular members, the second annular member being concentric with the first annular member. A mandrel extends perpendicularly to and intersects a horizontal plane defined by a substantially circular region of the second annular member substantially at the center of the circular region. Each of the annular members has a plurality of tubular guide wires slideably mounted thereon and a plurality of wires extend from the mandrel through each of the tubular wire guides. The first annular member rotates circumferentially relative to the second annular member. The first plurality of tubular wire guides slides radially inward to align with the second annular member, and the second plurality of tubular wire guides slides radially outward so as to align with the first annular member.

  • Patent number: 10260182
    Abstract: Methods of braiding using a braiding mechanism are described. The braiding mechanism includes a circular array of filament engagement elements, a mandrel extending from the center of the circular array, a plurality of actuators disposed operably about the circular array, and a rotating mechanism adapted to rotate one or more filaments. The circular array of filament engagement elements and the plurality of actuators are configured to move relative to one another. The plurality of filaments are loaded onto the mandrel and extend radially toward and contact the circumferential edge of the circular array of filament engagement elements. The plurality of actuators are operated to engage a first subset of the plurality of filaments and move the engaged filaments in a generally radial direction to a position beyond the circumferential edge of the circular array. The rotating mechanism is operated to move the engaged filaments about the mandrel axis.

  • Patent number: 10260183
    Abstract: Methods for forming a tubular braid are described. The method for braiding includes providing a braiding mechanism including a disc, a mandrel, and a plurality of actuators. The disc defines a plane and a circumferential edge and the mandrel extends from a center of the disc. A plurality of filaments are loaded on the mandrel, each extending radially toward the circumferential edge and contacting the disc at a point of engagement. The plurality of actuators are operated to engage and move a first subset of filaments in a generally radial direction to a position beyond the circumferential edge. The disc or the engaged first subset are rotated relative to one another, thereby crossing the first subset over a second subset of filaments. The actuators are then operated to move the first subset to a radial position on the circumferential edge different from its previous point of engagement.

  • Patent number: 8833224
    Abstract: Devices and methods for forming a tubular braid comprising a plurality of filaments. The method for braiding includes the step of loading a plurality of filaments on a mandrel and extending the filaments radially from the mandrel, the plurality of filaments have a first subset and a second subset. Tension is applied to the plurality of filaments using a weight attached to each filament. The first subset of the plurality of filaments is engaged, moved circumferentially relative to the second subset, and then released. The second subset of filaments is then engaged and moved circumferentially relative to the first subset of filaments, such that a tubular braid of filaments is formed.
