<p>A stent delivery system (10) includes a stent (28) positioned at a stent receiving portion (29) of an elongate shaft (22), the stent having a constrained configuration (40) and an expanded configuration. A first biasing member (52) is operably connected to the shaft and the stent and a second biasing member (54) 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.</p> |
