Detachable aneurysm neck bridge (III)
First Claim
1. A vaso-occlusive system, comprising:
- a vaso-occlusive device for occluding an aneurysm, the vaso-occlusive device having a first shape when being delivered to the aneurysm, and a second shape that is different from the first shape when the vaso-occlusive device is delivered within the aneurysm; and
a retainer assembly for retaining the vaso-occlusive device in the aneurysm, the retainer assembly comprising a core wire, an array element, and a joint between a distal end of the core wire and the array element, wherein the array element has a delivery shape when retained within an elongate tubular delivery device, and a deployed shape when outside the elongate tubular delivery device, and the joint is comparatively more susceptible to electrolytic severability than the core wire and the array element.

Abstract
This is a device for bridging the neck of either a wide-necked or narrow-necked aneurysm in the vasculature. In general, it is a device used to stabilize the presence of vaso-occlusive devices (such as helically wound coils) in the aneurysm. The device preferably is delivered by a core wire which terminates in an electrolytically severable joint. The core wire will often be insulated. The retainer assembly itself is also attached to the electrolytic joint and 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.
