Two-way shape memory vascular treatment systems

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.

主权项

1. A device for treating a vessel, the device comprising:
a plurality of wires woven to form a textile structure, the textile structure comprising:
a first shape at a first temperature,
wherein the first shape comprises a spiral and the first temperature is less than about 25° C.,a second shape at a second temperature higher than the first temperature,
wherein the second shape comprises a plurality of bulbs,the second shape different than the first shape, anda third shape comprising stress-induced martensite,
the third shape different than the first shape and the second shape, wherein the textile structure is configured to self-expand from the third shape to the second shape upon deployment from a sheath, and wherein the textile structure is configured to transform from the second shape to the first shape upon exposure to the first temperature or lower.
