1. A method for treating an aneurism, comprising:

  • providing a patch including a vessel interface side and an opposing non-interface side, the patch being formed of a sufficiently flexible material to provide a patch stowed state when the patch is delivered through the vessel and a patch deployed state when the patch is at least partially positioned over the mouth of the aneurism, the interface side of the patch being configured to form an adherence between the patch and an area of a vessel wall adjacent to the aneurism mouth, and wherein the patch includes an aperture for communication with the aneurism;

    introducing the patch through the vessel in the stowed state;

    positioning the patch at least partially adjacent to the aneurism so that the aperture is substantially adjacent to the mouth of the aneurism;

    deploying the patch from the stowed state to the deployed state; and

    forming an adherence between the patch and an area of a vessel wall adjacent to the aneurism mouth.
