1. A device for treating a vessel, the device comprising:
- a plurality of wires woven to form a textile structure,the textile structure comprising;
a proximal end,a distal end,a longitudinal axis extending from the proximal end to the distal end,a plurality of bulbs, anda plurality of necks,wherein the textile structure is expandable from a radially-compressed state to a radially-expanded state,wherein the plurality of wires comprises a plurality of shape-memory wires and a plurality of radiopaque wires,wherein pairs of bulbs of the plurality of bulbs are spaced along the longitudinal axis of the textile structure by a neck of the plurality of necks,wherein a first neck of the plurality of necks has a different neck parameter than a second neck of the plurality of necks at least when the textile structure is in the radially-expanded state,wherein the different neck parameter includes at least one of;
a neck length along the longitudinal axis, anda neck diameter transverse to the longitudinal axis.

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.
