1. A method for positioning a device for performing a therapeutic procedure in the vasculature of a patient, the method comprising:
extending a corewire distally relative to an overtube of an integrated guide structure within the vasculature to extend a distal reach of the device in a vessel, the corewire and overtube comprising torque coupling structure defining a range of extension achievable through the relative motion of the corewire and overtube, and the overtube having a distal end; and
guiding a therapeutic treatment device over the integrated guide structure to a treatment position at least a portion of which extends beyond the distal end of the overtube.
