A stent delivery system and a method for implanting a stent are provided. The system includes first and second elongate shafts, each shaft including a proximal portion, a distal portion, and a lumen extending at least partially therethrough. The second shaft is longitudinally movable relative to the first shaft. The system also includes a bifurcated stent having a first arm positioned on the first shaft and a second arm positioned on the elongate shaft and a main body positioned on the first and second shafts. Proximal and first and second distal constraining members are releasably connected to the stent. The proximal and the first and second distal constraining members cooperatively apply longitudinal tensile force to at least a portion of the stent with the proximal and first and second distal constraining members each in the first position.
