Methods and systems for preventing aneurysm rupture and reducing the risk of migration and endoleak are disclosed. Specifically, a hardenable liner is applied directly to treat the interior of the aneurysm site. The hardening agent remains flexible in the pliable mode so that the liner can be collapsed and compressed in a delivery catheter. After deploying in the aneurysm, the flexible liner expands by the hemodynamic force and conforms to the inner surface of the aneurysm. While the liner is still conforming to the aneurysm, the hardening agent in the liner is activated by the body environment and becomes stiff. The liner is thus transformed from the pliable mode to the strengthening mode and providing support for the aneurysm wall. Also disclosed are methods to deliver the hardenable liner directly to treatment sites. |
