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 measureable 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.

A device for treating a vessel, the device comprising:
- a plurality of wires woven to form a textile structure having a longitudinal axis,
- the textile structure expandable between a radially compressed state and a radially expanded state,
- the textile structure in the radially expanded state comprising:
- a first bulb having a first diameter and a first braid angle,
- a first neck having a second diameter less than the first diameter and having a second braid angle less than the first braid angle,
- a second bulb between the first bulb and the first neck along the longitudinal axis, the second bulb having a third diameter greater than the first diameter,
- a second neck between the first bulb and the second bulb along the longitudinal axis, the second neck having a fourth diameter less than the first diameter and less than the third diameter,
- a lateral neck extending from the first bulb at an angle to the longitudinal axis, the lateral neck having a first length, and
- a medial neck extending from the first bulb at an angle to the longitudinal axis, the medial neck having a second length less than the first length.
A device for treating a vessel, the device comprising:
- a plurality of wires forming a textile structure changeable between a radially compressed state and a radially expanded state,
- the textile structure comprising, in the radially expanded state:
- an anchor bulb having a first braid angle,
- a first neck extending from the anchor bulb, the first neck comprising:
- a first generally cylindrical portion proximate to the anchor bulb,
- a second generally cylindrical portion distant to the anchor bulb, and
- a second bulb between the first generally cylindrical portion and the second generally cylindrical portion,
- a second neck extending from the anchor bulb, the second neck having a second braid angle less than the first braid angle, and
- a third neck extending from the anchor bulb, the third neck having a third braid angle less than the first braid angle.
A device for treating a vessel, the device comprising:
- a plurality of wires forming a textile structure transformable between a radially compressed state and a radially expanded state,
- the textile structure comprising, in the radially expanded state:
- an first bulb having a first braid angle,
- a first neck extending from the first bulb,
- a second neck extending from the first bulb, the second neck having a second braid angle less than the first braid angle, and
- a third neck extending from the first bulb, the second neck having a third braid angle less than the first braid angle.
