摘要：
Methods, apparatuses and systems are described for expandable stent delivery apparatus to cover an access site. The method may include delivering the stent through an access site and deploying a distal portion of the stent from within an outer sheath. In some cases, the method may further include pushing a proximal portion of the stent from the outer sheath such that upon fully exiting the outer sheath, the proximal portion extends proximally to at least partially cover the access site with the stent. The system for delivering the stent into the body lumen may include a stent, a stent delivery apparatus, and an outer sheath. The system may further include an internal pusher configured to push a proximal portion of the stent from the outer sheath and axially compress the stent such that upon fully exiting the outer sheath, the proximal portion extends proximally to cover the access site.
