摘要： 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.

摘要： Woven structures and associated systems for weaving such structures are disclosed. Some disclosed innovations pertain to braided structures, such as braided wire structures, with axially asymmetric woven structures (or “directional meshes”) being examples. Other innovations disclosed herein pertain to methods of manufacturing woven structures, with automated methods of braiding directional meshes being examples. Some directional mesh embodiments can be configured and used as energizable electrodes for electrosurgical therapies, for example, bipolar vaporization therapies.

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： A braiding machine and methods of braiding are described. The braiding machine includes first and second annular members having inclined surfaces, the second annular member being concentric with the first annular member. The inclined surfaces are inclined at a non-zero angle formed between an axis of the outer ring and a horizontal axis that lies perpendicular to the longitudinal axis of the mandrel. 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. One of the first and second annular members rotates circumferentially relative to the other. The first plurality of tubular wire guides slides radially inward so as 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.
