Abstract
An implant for treating brain aneurysms, especially terminal aneurysms, comprises a neck cover and elongate shaft removably secured to an embolic delivery catheter. As such, the shaft aids in directing and placing the cover at the aneurysm neck, protecting the delivery catheter from adhesion with the embolic material, and securing the cover in place with connection or adhesion of the shaft to the embolic material delivered through the catheter. The implant can be anchored at the aneurysm either by interface and/or adhesion of the shaft or shaft and cover with the resident embolic materials.
