1. A system for delivering a stent into a body lumen, comprising:
a stent;
a stent delivery apparatus configured to deliver the stent through an access site in a wall of the body lumen;
an outer sheath configured to constrain a proximal portion of the stent in a collapsed configuration within the outer sheath while retracting the outer sheath toward the access site;
a tubular member configured to advance through the access site in the wall of the body lumen, wherein the stent is disposed on the tubular member such that the tubular member is inside the stent along a distal portion of the stent and outside of the stent along the proximal portion of the stent; and
an internal pusher configured to push the proximal portion of the stent from the outer sheath and axially compress the stent within the body lumen such that upon fully exiting the outer sheath, the proximal portion extends proximally to at least partially cover the access site with the stent.
