  • Patent number: 8820207
    Abstract: A tubular braid and mechanisms for forming the braid are described. The mechanism for braiding includes a disc, a mandrel, a plurality of catch mechanisms, and a plurality of actuators. The disc defines a plane and a circumferential edge. The mandrel extends from a center of the disc and is adapted to hold a plurality of filaments extending radially from the mandrel toward the circumferential edge of the disc. The plurality of catch mechanisms are positioned circumferentially around the edge of the disc and are adapted to engage a filament. The plurality of actuators are configured to move relative to one another and are adapted to move the plurality of catch mechanisms in a substantially radial direction relative to the circumferential edge of the disc.

  • Publication number: 20130239790
    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.

  • Patent number: 8430012
    Abstract: A device and method for forming a tubular braid comprising a plurality of filaments. The braiding machine comprises a disc with a mandrel extending from the center in a perpendicular direction and a plurality of catch mechanisms arranged circumferentially around the edge of the disc. A plurality of filaments are temporarily affixed to the mandrel, each filament extending from the mandrel toward the edge of the disc and engaging the edge of the disc at a discrete point of engagement. The plurality of catch mechanisms are attached to actuators adapted to move the catch mechanisms in a generally radial direction relative to the edge of the disc to allow the catch mechanism to engage a subset of the filaments and move the engaged filaments beyond the circumferential edge of the disc.

  • Publication number: 20130092013
    Abstract: Devices and methods for forming a tubular braid comprising a plurality of filaments. The braiding machine includes a circular array of filament guiding members defining a plane; a mandrel defining an axis and adapted to carry one or more filaments extending from the mandrel to the circular array; a plurality of filaments extending from the mandrel in a radial array; a plurality of actuator mechanisms disposed operably about the disc; and a rotating mechanism adapted to rotate one or more filaments. The actuator mechanisms and rotating mechanism are configured to move each of the one or more filaments about the mandrel axis in a path comprising a series of arcs and radial movements. The braiding machine may alternately first and second annular members, a mandrel, first and second plurality of tubular wire guides, and a plurality of wires extending from the mandrel.
