Patent ID: 8870910

Claim:
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 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, and a 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.
