Abstract

The self-expandable aneurysm filling device (102, 202), system and method provide for placement of the stent into an aneurysm (112) to at least partially fill and stabilize the aneurysm. The self -expandable aneurysm filling device (102) has a compressed undeployed configuration and an expanded three-dimensional deployed configuration, and a severable deployment junction (104, 204) releasably connects the self-expandable aneurysm filling device to a pusher wire (106, 206). The severable deployment junction can be mechanically, electrolytically, or thermally severed to separate the self-expandable aneurysm filling device from the pusher wire.

Description

[0001] Cross references to related patent applications

[0002] This patent application is based on US Provisional Patent Application No. 61 / 096,546, filed September 12, 2008, which is hereby incorporated by reference in its entirety. Background technique

[0003] The present invention generally relates to intravascular devices. More particularly, the present invention relates to endovascular devices for filling vascular conditions such as intracranial aneurysms.

[0004] Current treatment of cerebral aneurysms is by open surgical clipping of the aneurysm or by intervening endovascular access. The mainstay of interventional endovascular therapy involves placement of one or more coils via a microcatheter into the aneurysm sac. One of the drawbacks associated with interventional endovascular treatments is that "wide neck" aneurysms are generally immune to such treatments due to the possibility that the coil, once positioned, will not be successfully retained within the aneurys...
