Claim Text:
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, the distal constraining member comprising a distal retaining wire, a first distal loop and a second distal loop, the first distal loop extending through a plurality of peaks of the stent, the distal retaining wire releasably extending through the first and second distal loops, the 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, the proximal and distal constraining members releasably locking the stent to the elongate shaft and allowing the stent to move between the constrained configuration and the expanded configuration, the stent in the expanded configuration is fully expandable and free from constraint by an outer sheath without release from the elongate shaft.
