This is a device for bridging the neck of either a wide-necked or narrow-necked aneurysm in the vasculature and stabilizing the presence of vaso-occlusive devices (such as helically wound coils) in that aneurysm. The retainer assembly may be delivered from its attachment to the distal end of a tubular member preferably by the severance of by an included electrolytically severable joint. The retainer assembly itself typically has a number of array elements which are intended to be resident within the aneurysm after the device is deployed from the distal end of a catheter. After deployment of this retainer, the aneurysm is at least partially filled with a vaso-occlusive device such as helically wound coils. |
