    摘要： Methods of braiding using a braiding mechanism are described. The braiding mechanism includes an array of filament engagement elements, a mandrel extending from the center of the circular array, a plurality of actuators disposed operably about the array, and a rotating mechanism adapted to rotate one or more filaments. The plurality of filaments are loaded onto the mandrel by looping a middle portion of each filament of the plurality of filaments over an end of 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 array. The rotating mechanism is operated to move the engaged filaments about the mandrel axis.

    摘要： Devices and methods for treatment of a patient's vasculature are described. Embodiments may include a permeable implant having a radially constrained state configured for delivery within a catheter lumen, an expanded state, and a plurality of elongate filaments that are woven together. The permeable implant may include a stiffer proximal portion that is configured to sit at the neck of an aneurysm. The stiffer proximal portion may include coils, stiffening elements, or reinforcement elements disposed about or associated with the filaments or woven together with the filaments.

    摘要： 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.

    摘要： Devices for treatment of a cerebral aneurysm are described. Embodiments may include a self-expanding permeable shell having a radially constrained elongated state configured for delivery within a catheter lumen, an expanded state with a globular and longitudinally shortened configuration relative to the radially constrained state, and a plurality of elongate filaments that are woven together, which define a cavity of the permeable shell. The permeable shell includes composite filaments. The composite filaments include drawn filled tube wires having an external nitinol tube and a highly radiopaque material concentrically disposed within the external tube. The composite filaments may have a diameter of 0.00075″, 0.001″, 0.0015″, and/or 0.00125″.

    摘要： Devices and methods for treatment of a patient's vasculature with some embodiments configured for delivery with a microcatheter for treatment of the cerebral vasculature of a patient. Embodiments may include a self-expanding resilient permeable shell having a radially constrained elongated state configured for delivery within a catheter lumen, an expanded state with a globular and longitudinally shortened configuration relative to the radially constrained state, and a plurality of elongate filaments which are woven together, which define a cavity of the permeable shell Some embodiments may include at least about 40% composite filaments having a high strength material and a highly radiopaque material. In some embodiments, the total cross sectional area of the highly radiopaque material is between about 11% and about 30% of the total cross sectional area of the plurality of elongate elements.
