METHODS OF MANUFACTURING SLOTTED VASCULAR TREATMENT 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 vascular treatment device, the method comprising:
holding a hypotube using at least one bushing and at least one collet; cutting a pattern comprising a plurality of kerfs into the hypotube, wherein cutting the pattern comprises:
directing a focused laser beam at the hypotube, the focused laser creating a heat impact puddle, the heat impact puddle being less than a width and a length of each of the plurality of kerfs, andlongitudinally and rotationally moving the hypotube in a design such that the focused laser beam cuts the hypotube to form the plurality of kerfs; and during cutting the pattern, flowing fluid through the hypotube.
