Abstract

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.

First claim

What is claimed is:

1. A stent comprising:
a stent body; and
a deployable member coupled with the stent body and configured to hinge from inside of the stent body, align with an outer surface of the stent body after hinging from the inside of the stent body, and increase a body lumen contact surface area of the stent, wherein the deployable member is configured to hinge from inside of the stent body to outside of the stent body to increase the body lumen contact surface area of the stent.

2. The stent of claim 1 , wherein the deployable member is configured to extend in length axially in a direction away from the stent body.

3. The stent of claim 1 , wherein the deployable member comprises at least one flap hingedly coupled with the stent body and configured to hinge from inside of the stent body.

4. The stent of claim 1 , wherein the deployable member comprises a plurality of flaps hingedly coupled with the stent body and equidistantly spaced around a circumference of the stent body, wherein the plurality of flaps are configured to hinge from inside of the stent body.

5. The stent of claim 1 , wherein the deployable member is sized to cover a body lumen access hole of a body lumen through which the stent accessed the body lumen.
