摘要：
Methods, apparatuses and systems are described for delivering a stent through an access hole of a body lumen and covering up the access hole after deploying the stent. Stents are described that include a stent body defining a body lumen contact surface area and a deployable member configured to deploy from the stent body and increase the body lumen contact surface area of the stent. Deployable members that hinge, unroll, extend, expand, and coaxially translate with respect to the stent body are described. A system for delivering a stent into a body lumen are described that may include a coverage member configured to at least partially cover the hole in the wall of the stent upon withdrawing a tubular member through the hole in the wall of the stent. Coverage members may include a self-sealing membrane, a flap valve, or a hinged valve.
