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 vascular cavity, the device comprising:
- a plurality of wires woven to form a 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, the first bulb having a first braid angle, the first bulb having a first diameter, the first bulb having a porosity configured to decrease flow into and out of the vascular cavity,
- a second bulb, the second bulb having a second braid angle less than the first braid angle, the second bulb having a second diameter,
- a third bulb, the second bulb between the first bulb and the third bulb, the third bulb having a third braid angle less than the first braid angle, the third bulb having a third diameter less than the first diameter,
- a first neck between the first bulb and the second bulb, the first neck having a fourth braid angle less than the first braid angle, the first neck having a fourth diameter less than the first diameter and the second diameter,
- a second neck between the second bulb and the third bulb, the second neck having a fifth braid angle less than the first braid angle, the second neck having a fifth diameter less than the second diameter and the third diameter,
- a third neck extending from the third bulb, and
- a fourth neck extending from the first bulb.
A device for treating a vascular cavity, the device comprising:
- a textile structure changeable between a radially compressed state and a radially expanded state,
- the textile structure comprising, in the radially expanded state, a plurality of bulbs along a longitudinal axis from a proximal end to a distal end, wherein the plurality of bulbs comprises a proximal-most bulb having a first braid angle, at least one bulb distal to the proximal-most bulb having a second braid angle less than the first braid angle,
- each said bulb longitudinally spaced from another said bulb by a neck, at least one neck distal to the proximal-most bulb having a third braid angle less than the first braid angle,
- the proximal-most bulb of the plurality of bulbs having a porosity configured to reduce flow into the vascular cavity;
- and
- a proximal portion coupled to the textile structure at a joint proximal to the proximal-most bulb,
- the textile structure detachable from the proximal portion at the joint.
A device for treating a vascular cavity, the device comprising:
- a structure transformable between a radially compressed state and a radially expanded state,
- the structure comprising, in the radially expanded state, a plurality of bulbs, wherein the plurality of bulbs comprises a proximal-most bulb having a first braid angle, at least one bulb distal to the proximal-most bulb having a second braid angle less than the first braid angle,
- each said bulb longitudinally spaced from another said bulb by a neck, at least one neck distal to the proximal-most bulb having a third braid angle less than the first braid angle,
- the proximal-most bulb having a porosity configured to inhibit flow into the vascular cavity.
