Variable porosity flow diverting devices
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.
1. An implantable device for treating a vascular cavity, the device comprising:
a plurality of wires woven to form a textile structure expandable from a compressed state to an expanded state,
the textile structure comprising, in the expanded state:
a first bulb comprising a first braid angle, a first diameter, and a first shape,
a second bulb comprising a second braid angle, a second diameter, and a second shape,
a first neck between the first bulb and the second bulb,
a third bulb comprising a third braid angle, a third diameter, and a third shape, the second bulb between the first bulb and the third bulb,
a second neck between the second bulb and the third bulb, and
a lumen configured to allow perfusion of blood through the textile structure,
wherein the first braid angle is greater than the second braid angle and the third braid angle,
wherein the second bulb comprises a first portion having the second braid angle and a second portion having the first braid angle, the second portion proximate to the first bulb.
