Methods of manufacturing variable porosity devices

摘要

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. A method of manufacturing a device for treating a vessel, the method comprising:
arranging a plurality of spools on a yarn wheel, each of the spools comprising wire; braiding the wire from each of the plurality of spools for a first duration to form a first segment of a textile structure, wherein braiding the wire during the first duration comprises pulling a ring away from the yarn wheel at a first speed; after forming the first segment, rearranging at least some of the plurality of spools on the yarn wheel, wherein rearranging at least some of the plurality of spools forms empty spindle pairs; and after rearranging at least some of the plurality of spools, braiding the wire from each of the plurality of spools for a second duration to form a second segment of the textile structure, wherein braiding the wire during the second duration comprises pulling the ring away from the yarn wheel at a second speed different than the first speed, wherein the second segment has a different porosity than the first segment, wherein at least one of the first duration and the second duration comprises:
a third duration, anda fourth duration after the third duration, wherein braiding the wire during the third duration comprises rotating the yarn wheel for 180° at a third speed, and wherein braiding the wire during the fourth duration comprises rotating the yarn wheel for 180° at a fourth speed different than the third speed.
