Methods of manufacturing flow diverting 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 measurable 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 first mandrel extension on a bulbous mandrel, wherein arranging the first mandrel extension comprises coupling the first mandrel extension to a first sprocket in a first retainer in the bulbous mandrel; arranging a second mandrel extension on the bulbous mandrel, wherein arranging the second mandrel extension comprises coupling the second mandrel extension to a second sprocket in a second retainer in the bulbous mandrel; arranging a third mandrel extension on the bulbous mandrel, wherein arranging the third mandrel extension comprises coupling the third mandrel extension to a third sprocket in a third retainer in the bulbous mandrel; after arranging the first mandrel extension, the second mandrel extension, and the third mandrel extension, removing sprockets that are not coupled to the first mandrel extension, the second mandrel extension, or the third mandrel extension from other retainers in the bulbous mandrel; and braiding a plurality of wires over the bulbous mandrel, the first mandrel extension, the second mandrel extension, and the third mandrel extension to form a textile structure comprising:
a first bulb,a first neck,a second bulb between the first bulb and the first neck,a second neck between the first bulb and the second bulb, the first neck, the second bulb, and the second neck extending from the first bulb along a longitudinal axis,a lateral neck extending from the first bulb at a first angle to the longitudinal axis, anda medial neck extending from the first bulb at a second angle to the longitudinal axis.
