A stent delivery system and a method for releasably constraining a stent and a method of implanting a stent are provided. The stent delivery system includes 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. The stent delivery system also includes a stent positioned at the stent receiving portion of the elongate shaft, the stent having a constrained configuration and an expanded configuration. A first biasing member is operably connected to the shaft and the stent and a second biasing member is operably connected to the shaft and the stent. The first and second biasing members have a first configuration cooperatively applying a longitudinal tensioning force to the stent and a second configuration cooperatively releasing the longitudinal tensioning force on the stent.
