Abstract
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.
Claims20
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, and
- at 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.
A device for facilitating measurement in a vessel, the device comprising:
- a plurality of wires woven to form a self-expanding textile structure, the plurality of wires comprising shape-memory wires and at least two radiopaque wires forming at least two longitudinally offset sine waves visibly distinct from the shape memory wires under x-ray;
- a first section comprising the at least two longitudinally offset sine waves substantially uniformly spaced by a first distance;
- and
- a second section comprising the at least two longitudinally offset sine waves substantially uniformly spaced by a second distance different than the first distance.
