WOVEN RADIOPAQUE PATTERNS

摘要

Vascular treatment and methods include a plurality of self-expanding bulbs and a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Joints between woven structures and hypotubes include solder. Woven structures include patterns of radiopaque filaments measurable under x-ray. Structures are heat treated to include at least shapes at different temperatures. A catheter includes a hypotube including interspersed patterns of longitudinally spaced rows of kerfs. Heat treating systems include a detachable flange. Laser cutting systems include a fluid flow system.

主权项

1. A device for facilitating measurement in a vessel, the device comprising:
a plurality of wires woven to form a self-expanding textile structure, the self-expanding textile structure comprising a plurality of woven bulbs in a non-compressed state, the plurality of wires comprising:
shape-memory wires, andat least two radiopaque wires forming at least two longitudinally offset sine waves visibly distinct from the shape memory wires under x-ray, wherein the at least two longitudinally offset sine waves facilitate length measurement in the vessel.
