摘要：
Methods, apparatuses and systems are described for stent delivery and positioning to cover an access site. The method may include delivering the stent through an access site in a wall of the body lumen. In some cases, the method may include repositioning the stent within the body lumen to at least partially cover the access site with the stent. The stent may be repositioned within the body lumen by retracting the stent towards the access site such that a proximal portion of the stent at least partially covers the access site. The stent may then expand within the body lumen. In some cases, the stent may expand within the body lumen by releasing a primary constrainment member from the stent by pulling the primary constrainment member in a proximal direction away from the stent.
