Abstract
Methods, apparatuses and systems are described for stent delivery and positioning to cover an access site. A stent delivery system may include a tubular member configured to advance through an access site and a primary constrainment member configured to releasably couple the stent to the tubular member. The stent delivery system may further include a secondary constrainment member at least partially disposed around the primary constrainment member, the stent, and the tubular member. In some cases, the tubular member and the primary constrainment member may be configured to reposition the stent within the body lumen after removal of the secondary constrainment member such that at least a portion of the stent covers the access site after withdrawal of the tubular member, the primary constrainment member, and the secondary constrainment member from the body lumen through the access site.
