1. A stent delivery system comprising:

  • an elongate shaft including a proximal portion, a distal portion, a lumen extending at least partially therethrough, and a stent receiving portion on the distal portion of the shaft;

    a stent positioned at the stent receiving portion of the elongate shaft, the stent having a constrained configuration and an expanded configuration;

    a proximal constraining member releasably connected to a proximal portion of the stent and having a first position and a second position;

    a distal constraining member releasably connected to a distal portion of the stent and having a first position and a second position;

    the proximal constraining member and the distal constraining member cooperatively apply a longitudinal tensile force to at least a portion of the stent in the constrained configuration with the proximal and distal constraining members each in the first position.
