1. An aneurysm filling apparatus for treatment of an aneurysm, comprising:
- a self-expandable aneurysm filling device having a compressed undeployed configuration and an expanded three-dimensional deployed configuration, wherein the self-expandable aneurysm filling device transforms from the compressed configuration to the expanded three-dimensional configuration as it is deployed;
a pusher wire; and
a severable deployment junction releasably connecting said self-expandable aneurysm filling device to said pusher wire.

Abstract
The self-expandable aneurysm filling device, system and method provide for placement of the stent into an aneurysm to at least partially fill and stabilize the aneurysm. The self-expandable aneurysm filling device has a compressed undeployed configuration and an expanded three-dimensional deployed configuration, and a severable deployment junction releasably connects the self-expandable aneurysm filling device to a pusher wire. The severable deployment junction can be mechanically, electrolytically, or thermally severed to separate the self-expandable aneurysm filling device from the pusher wire.

12. A self-expandable aneurysm filling system for deploying a self-expandable aneurysm filling device into an aneurysm from a parent vessel for treatment of the aneurysm to at least partially fill and stabilize the aneurysm, comprising:
-
a self-expandable aneurysm filling device having a compressed undeployed configuration and an expanded three-dimensional deployed configuration; a pusher wire; a severable deployment junction releasably connecting said self-expandable aneurysm filling device to said pusher wire; and a microcatheter for delivering the self-expandable aneurysm filling device in the compressed configuration into an aneurysm for treatment of the aneurysm, wherein the self-expandable aneurysm filling device transforms from the compressed configuration to the expanded configuration as it is deployed through the microcatheter. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of deploying a self-expandable aneurysm filling device into an aneurysm from a parent vessel for treatment of the aneurysm to at least partially fill and stabilize the aneurysm, comprising the steps of:
-
providing a self-expandable aneurysm filling device having a compressed undeployed configuration and an expanded three-dimensional deployed configuration, a pusher wire, a severable deployment junction releasably connecting said self-expandable aneurysm filling device to said pusher wire, and a microcatheter for delivering the self-expandable aneurysm filling device in the compressed configuration into an aneurysm for treatment of the aneurysm; delivering the self-expandable aneurysm filling device in the compressed configuration in an undeployed state through the microcatheter to an aneurysm; inserting a distal portion of the microcatheter inside the aneurysm; pushing the self-expandable aneurysm filling device through the microcatheter with the pusher wire until the self-expandable aneurysm filling device exits the microcatheter, wherein the self-expandable aneurysm filling device transforms from the compressed configuration into the expanded configuration as it exits through the microcathether; allowing the self-expandable aneurysm filling device to expand within the aneurysm to achieve a completely deployed state; separating the self-expandable aneurysm filling device from the pusher wire; and withdrawing the microcatheter and pusher wire from the parent blood vessel. - View Dependent Claims (24, 25, 26)
