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.
Claims22
A device for treating a vessel, the device comprising:
- a plurality of wires,
- the plurality of wires woven to form a textile structure,
- the textile structure comprising:
- a proximal end,
- a distal end,
- at least three woven bulbs, and
- a longitudinal axis,
- wherein the distal end of each of the plurality of wires is trimmed along a plane substantially transverse to the longitudinal axis of the textile structure, thereby generating cut distal ends of the plurality of wires that are configured to provide at least one of flexibility and reduced risk that the vessel will be punctured by the device.
A device for treating a vessel, the device comprising:
- a plurality of wires,
- the plurality of wires woven to form a textile structure,
- the textile structure comprising:
- a longitudinal axis,
- a lumen parallel to the longitudinal axis, and
- a plurality of woven bulbs,
- wherein the textile structure comprises a proximal end and a distal end,
- the distal end of the textile structure comprising a distal end of each of the plurality of wires trimmed along a plane substantially transverse to the longitudinal axis of the textile structure,
- the distal end of the textile structure comprising an end treatment selected from the group consisting of:
- a polymer coating at least the distal ends of the plurality of wires, and
- a radiopaque marker coupled to the distal ends of the plurality of wires,
- the end treatment maintaining the lumen of the textile structure.

(canceled)
A device for treating a vessel, the device comprising:
- a plurality of wires woven to form a textile structure,
- the textile structure comprising a distal end comprising a polymer coating,
- the polymer coating comprising radiopaque particles, wherein the distal end of the textile structure is at least partially defined by distal ends of the plurality of wires trimmed along a plane substantially transverse to a longitudinal axis of the textile structure.
