1. A method of treating a vessel, the method comprising:
- positioning a distal portion of a treatment device in the vessel,the distal portion comprising;
a plurality of filaments, andpores between the filaments,the treatment device comprising a proximal portion comprising;
a wire comprising shape-memory material, the wire comprising;
a distal section including a distal end, the distal section of the wire comprising;
a first shape at a first temperature, and
a second shape at a second temperature different than the first temperature, the second shape being a straightened form of the first shape,a coiling portion proximal to the distal section and proximal to a proximal end of the distal portion, the coiling portion of the wire comprising;
a coil at the first temperature; and
a straightened form of the coil at the second temperature, anda proximal end proximal to the coiling portion,the distal portion coupled to the proximal portion at least by the pores between the filaments being entangled with the wire in the first shape; and
decoupling the proximal portion of the treatment device and the distal portion of the treatment device, wherein, during decoupling, the proximal end of the wire retracts proximally due to straightening of the coil.

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 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.

11. A method of treating a vessel, the method comprising:
-
positioning a distal portion of a treatment device in the vessel, the distal portion comprising; a plurality of filaments, and pores between the filaments, the treatment device comprising a proximal portion comprising; a wire comprising shape-memory material, the wire having a distal section, the distal section of the wire comprising; a first shape at a first temperature, wherein the first temperature is 25°
C.,a second shape at a second temperature, wherein the second temperature is 37°
C., the second shape being an expanded form of the first shape, anda third shape at a third temperature, wherein the third temperature is 18°
C., the third shape being a straightened form of the first shape,the distal portion coupled to the proximal portion at least by the pores between the filaments being entangled with the wire in the first shape; and decoupling the proximal portion of the treatment device and the distal portion of the treatment device, wherein decoupling comprises changing the wire to the third temperature. - View Dependent Claims (12, 13, 14, 15, 16, 17)
