Beschreibung
Zusammenfassung:	Stent delivery device includes an inner member having a distal tip, a stent disposed over a stent receiving region of the inner member, an outer sheath slidable over the inner member, a stent sheath removably coupled to both the distal tip and a distal end of the outer sheath, and a stent expanding element attached to the distal tip and/or the distal end of the outer sheath. The stent expanding element is biased in an elevated position and aids expansion of the stent when the stent sheath is removed. The stent delivery device includes a proximal junction removably coupling the distal end of the outer sheath to the stent sheath, and a proximal junction removably coupling the stent sheath to the distal tip. Each of the proximal and distal junctions are separately actuatable to decouple the stent sheath from either the distal tip or the outer sheath.
