Abstract
An improved aneurysm liner is used for treating an aneurysm in a parent vessel. The parent vessel defines a lumen. The aneurysm includes a neck and an inner wall defining a cavity in fluid communication with the lumen. The liner device is configured for deployment within the cavity. The device includes an extender inside an expandable aneurysm liner. The proximal pusher end of the extender receives force from a distal end of a delivery catheter for maneuvering the device into a deployment position. The device is arranged such that, when deployed within the cavity, the liner is expanded to fill the cavity. In treating an aneurysm, the liner device is directed to the aneurysm site by a guidewire that extends through the extender. Upon removal of the guidewire, the extender is released within the liner and the liner is expanded to fill the cavity.
