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.
Claims20
A method of manufacturing a vascular treatment device, the method comprising:
- arranging a plurality of spools on a yarn wheel, at least some of the spools comprising radiopaque wires and at least some of the spools comprising shape memory wires;
- braiding the radiopaque wires and the shape memory wires in a one-over-one-under-one pattern around a first mandrel to form a textile structure;
- shape setting the textile structure in a substantially cylindrical shape;
- providing a second mandrel comprising bulbs and necks, wherein the second mandrel comprises the bulbs threaded along a strand;
- securing the shape-set textile structure on the second mandrel, wherein securing the shape-set textile structure on the second mandrel comprises wrapping at least one of bangles and c-shaped clamps around the necks of the second mandrel;
- shape setting the shape-set textile structure on the second mandrel;
- and
- removing the shape-set textile structure from the second mandrel.
