Abstract
Methods, apparatuses and systems are described for expandable stent delivery apparatus to cover an access site. The method may include delivering a stent delivery system through an access site, where the stent delivery system comprises a positioning member with a first portion that is rotatable with respect to a second portion, and where the stent is releasably coupled with the first portion of the positioning member. In some cases, the method may further include withdrawing an outer constrainment member from the stent to deploy a proximal portion of the stent within the body lumen and rotating the proximal portion of the stent away from the access site by withdrawing the positioning member proximally and back through the access site. The method may further include covering the access site with the proximal portion of the stent upon fully deploying the proximal portion from the outer constrainment member.
