STENT DELIVERY SYSTEM

Stent delivery device including an inner member having a distal tip, a stent support member, and a stent disposed over a stent receiving region of the stent support member. An elongated outer sheath is slidably disposed over the inner member and the stent. The stent delivery device includes a distal junction removably coupling the distal end of the outer sheath to the distal tip, where the distaljunction is actuatable to decouple the outer sheath from the distal tip. The stent delivery device includes a proximal junction removably coupling a distal portion of the outer sheath to a proximal portion of the outer sheath, where the proximal junction is actuatable to decouple the distal portion of the outer sheath from the proximal portion of the outer sheath. The distal and proximal junctionsmay be separately actuatable by rotating the inner member relative to the proximal portion of the outer sheath. 支架输送装置包括具有远侧末端的内构件，支架支撑构件和设置在所述支架支撑构件的支架接收区域上方的支架。细长的外护套可滑动地设置在所述内构件和所述支架的上方。所述支架输送装置包括远侧接合部，其将所述外护套的所述远端可拆离地联接到所
