The stent delivery device also includes a collapsible frame attached to the distal region of the elongate shaft. The collapsible frame includes a plurality of arms configured to surround a stent such that the plurality of arms define a stent containment region. The stent delivery device also includes an inner member extending within a least a portion of the stent containment region and an actuation member configured to actuate the plurality of arms of the collapsible frame from an expanded configuration to a collapsed configuration.
